Docker

cache

docker:cache

Docker Cache, builds a Docker image as a cache to be reused in future builds.

It helps avoid redundant downloads of network resources such as dependencies.

Parameters

dockerfile

type: String
required: true

The path to the Dockerfile used to build the cache image.

To avoid excessively long build times, the Docker image build timeout is controlled by the job.timeout parameter.

by

type: Array<String> | String
required: false

Specifies the list of files that the cache image build process depends on.

Note: Files not listed in by, except for the Dockerfile, are treated as non-existent during the image build process.

Supports array format
Supports string format, with multiple files separated by commas.

versionBy

type: Array<String> | String
required: false

Used for version control. If versionBy is not provided, it defaults to the value of by.

When the content of the file pointed to by versionBy changes, a new version is considered. The calculation logic is based on the expression:

sha1(Dockerfile + versionBy + buildArgs + target + arch)

Supports array format
Supports string format, with multiple files separated by commas.

buildArgs

type: Object
required: false

Inserts additional build arguments during build (--build-arg $key=$value). If the value is null, only the key is added (--build-arg $key).

target

type: String
required: false

Corresponds to the --target parameter in docker build, allowing selective building of specific stages in the Dockerfile instead of the entire Dockerfile.

sync

type: Boolean
required: false
default: false

Specifies whether to operate in synchronous mode. If true, it waits for the cache image to be successfully pushed before proceeding with subsequent tasks.

ignoreBuildArgsInVersion

type: Boolean
required: false
default: false

Specifies whether to ignore buildArgs in version calculation.

See Version Control

Output Results

{
  // The docker image name corresponding to the cache
  name;
}

Configuration Examples

.cnb.yml
main:
  push:
    - docker:
        image: node:14
      stages:
        - name: build cache image
          type: docker:cache
          options:
            dockerfile: cache.dockerfile
            # by supports two formats: array, string
            by:
              - package.json
              - package-lock.json
            versionBy:
              - package-lock.json
          exports:
            name: DOCKER_CACHE_IMAGE_NAME
        - name: use cache
          image: $DOCKER_CACHE_IMAGE_NAME
          commands:
            - cp -r "$NODE_PATH" ./node_modules
        - name: build with cache
          script:
            - npm run build

Where cache.dockerfile is a Dockerfile used to build the cache image, for example:

# Choose a Base image
FROM node:14

# Set working directory
WORKDIR /space

# Copy the file list from 'by'
COPY . .

# Install dependencies based on the copied files
RUN npm ci

# Set the required environment variables
ENV NODE_PATH=/space/node_modules

cnb

await-resolve

cnb:await
cnb:resolve

await waits for the execution of resolve, which can pass variables to await.

Through await-resolve, multiple concurrent pipelines can cooperate with each other, enabling more flexible sequence control.

Tips

Difference between await-resolve and apply, trigger:

The former refers to a pipeline in a build that waits at an await task until it receives a resolve notification from another pipeline corresponding to the key before continuing.

The latter triggers a new pipeline from an existing one. It can be asynchronous, synchronous, and can even span repositories.

Usage Limitations

Can only await and resolve pipelines triggered by the same event.
A key can only be resolved once but can be awaited multiple times.
Group await and resolve operations using a key.
Await-resolve tasks can only run in the 'stages' of the pipeline, not in the 'endStages' and 'failStages'.

Deadlock Detection

While await and resolve can provide flexible flow control, they can introduce complex edge cases such as:

Deadlocks
- Pipeline-1 and Pipeline-2 await each other
- Multiple pipelines form an await loop
Infinite waiting
- Awaiting a non-existent key or a key without a corresponding resolve
- Failure in the pipeline where resolve is executed
Duplicate resolves
- Multiple resolve tasks associated with the same key

The deadlock detection mechanism automatically detects these anomalies, terminates the await's waiting state, and throws a dead lock found. exception.

The order of await and resolve in the configuration file does not affect the execution result. The final await task will always wait for the corresponding resolve to complete, and this scenario will not be terminated by the deadlock detection mechanism.

Applicable Events

All Events

Await Parameters

key

type: String
required: true

Pairing ID

Resolve Parameters

key

type: String
required: true

Pairing ID

data

type: object
required: false

Object to be passed

In key: value format, supports multiple levels. Example:

- name: resolve a json
  type: cnb:resolve
  options:
    key: demo
    data:
      a: 1
      b:
        c: 2

The result of the await task is the data object declared by resolve. This object can be accessed through exports. Example:

- name: await a json
  type: cnb:await
  options:
    key: demo
  exports:
    a: VAR_A
    b.c: VAR_B
- name: show var
  script:
    - echo ${VAR_A} # 1
    - echo ${VAR_B} # 2

Alternatively, you can simply indicate a waiting action without passing any content:

- name: ready
  type: cnb:resolve
  options:
    key: i-am-ready

- name: ready
  type: cnb:await
  options:
    key: i-am-ready

Output Results

{
  // Content returned by resolve
  data
}

Pass business-defined environment variables visible to the current job in the new pipeline.

Default values include the following environment variables that cannot be overridden by users:

APPLY_TRIGGER_BUILD_ID (similar to CNB_BUILD_ID in default CI environment variables)
APPLY_TRIGGER_PIPELINE_ID (similar to CNB_PIPELINE_ID in default CI environment variables)
APPLY_TRIGGER_REPO_SLUG (similar to CNB_REPO_SLUG in default CI environment variables)
APPLY_TRIGGER_REPO_ID (similar to CNB_REPO_ID in default CI environment variables)
APPLY_TRIGGER_USER (similar to CNB_BUILD_USER in default CI environment variables)
APPLY_TRIGGER_BRANCH (similar to CNB_BRANCH in default CI environment variables)
APPLY_TRIGGER_COMMIT (similar to CNB_COMMIT in default CI environment variables)
APPLY_TRIGGER_COMMIT_SHORT (similar to CNB_COMMIT_SHORT in default CI environment variables)
APPLY_TRIGGER_ORIGIN_EVENT (similar to CNB_EVENT in default CI environment variables)

Config Value Priority

Values are retrieved in the following order until a value is found:

config
configFrom
.cnb.yml in the current repository
If apply is called in the pull_request.merged event, the merged configuration file is used
If apply is called in the pull_request.target or pull_request.mergeable events, the configuration file of the target branch is used
Otherwise, the configuration file of the current branch is used

The configFrom parameter only supports local files like ./test/.cnb.yml. If you need to use a remote file, you should download it locally first.

}

Configuration Examples

Basic Usage

Trigger a pipeline in the main branch of a specified repository in the current repository.

The pipeline configuration file uses the .cnb.yml file from the main branch of the repository.

Use the access token $TOKEN to check if the user has permission to trigger the target repository pipeline.

cnb.yml
main:
  push:
    - stages:
        - name: trigger
          type: cnb:trigger
          imports: https://cnb.cool/<your-repo-slug>/-/blob/main/xxx/envs.yml
          options:
            token: $TOKEN
            slug: a/b
            branch: main
            event: api_trigger_test

read-file

cnb:read-file

Reads the content of a specified file, which can be exported as an environment variable for use in subsequent tasks.

Using the ##[set-output key=value] command to output variables is more convenient but will display the content in the logs, making it unsuitable for sensitive information.

For sensitive information that is predetermined, you can use imports for importing, and for sensitive information generated during the build process, you can write it to a file and use this built-in task to read it.

imports only supports files existing in remote repositories, while this built-in task only supports reading files that exist locally.

The file type is determined by the suffix, currently supporting .json, .yml, .yaml, and plain text (key=value structure).

            - echo $ENV_DEEP_MY_VAR
            - echo $ENV_ENV_KEY_MY_VAR

destroy-token

cnb:destroy-token

A CNB_TOKEN is created before the pipeline starts and is destroyed after it ends. Use this task to proactively destroy the CNB_TOKEN and remove this environment variable.

Applicable Events

Parameters

None

Output

None

Configuration Examples

Proactively destroy the CNB_TOKEN after use in the pipeline to reduce the risk of CNB_TOKEN misuse.

        - name: use CNB_TOKEN
          script: echo "Make API calls using the CNB_TOKEN."
        - name: destroy token
          type: cnb:destroy-token

vscode

go

vscode:go

Difference in configuring this built-in task for Workspaces:

Using this task: When starting cloud-native development, you need to wait for this task to complete before the WebIDE and VSCode/Cursor client entry points appear.
Not using this task: After the pipeline's prepare stage completes (code-server code service starts), the WebIDE and VSCode/Cursor client entry points will appear before the stages tasks are executed.

The difference in the timing of the appearance of the entry points mentioned above refers to the transition from the loading waiting page to the entry point selection page. In reality, whether or not this task is used, Workspaces is already available once the code-server code service has started.

Note: Using this task will increase the waiting time. If you need to delay developers' entry into the environment until certain tasks are completed, you can use this task.

Parameters

mergeType

mergeType

type: merge | squash | rebase | auto
required: false
default: auto

Merge strategy, defaulting to auto: merges by merge if multiple people contribute, otherwise uses squash.

mergeCommitMessage

type: String
required: false

Commit message for the merge.

When the merge strategy is rebase, this information is not required.
When the merge strategy is merge, the default message is chore: merge node(merged by CNB), automatically appending PR references, reviewers' names, and contributors' names. For example:

chore: merge node(merged by CNB)

PR-URL: !916
Reviewed-By: tom
Reviewed-By: jerry
Co-authored-by: jack

When the merge strategy is squash, the default value is the first commit message of the PR. It also appends PR references, reviewers' names, and contributors' names. For example:

.cnb.yml
main:
  pull_request.mergeable:
    - stages:
        - name: automerge
          type: git:auto-merge
          options:
            mergeType: squash

This configuration will result in the following effect:

Suppose a PR (feat/model-a -> main) has two commit records:

Commit 1: Submitted on October 1, 2023

feat(model-a): Add a new feature to module A

Due to some reason, add a certain feature

close #10

Commit 2: Fixed some issues pointed out during code review, submitted on October 2, 2023

fix(model-a): Fix issues pointed out during review

After automatic merging, a commit node like this will appear on the main branch, where the subsequent commit record (Commit 2) will be erased:

feat(model-a): Add a new feature to module A

Due to some reason, add a certain feature

close #10

Here’s the translation of your Chinese text into English:

It can also be directly specified

For example, specifying it as the title of the current PR through an environment variable:

.cnb.yml
main:
  pull_request.mergeable:
    - stages:

          type: git:auto-merge
          options:
            mergeCommitMessage: $CNB_PULL_REQUEST_TITLE

mergeCommitFooter

type: String
required: false

Footer information to be set for the merge, with multiple footers separated by \n, effective only for merge and squash.

When the merge strategy is rebase, this information is not required.

When the merge strategy is merge or squash, the provided information will be added as footers line by line, followed by PR references, reviewers' names, and contributors' names. For example:

.cnb.yml
main:
  pull_request.mergeable:
    - stages:

removeSourceBranch

type: Boolean
required: false
default: false

Whether to delete the source branch after merging.

This value is irrelevant when the source branch and target branch are in different repositories.

ignoreAssignee

type: Boolean
required: false
default: false

Whether to ignore the assignee.

When a PR has a specified assignee, this task will not automatically merge the PR because the assignee is meant to assign someone to handle it manually.

Setting this to true allows for forcibly merging the PR even if there is an assignee.

Output Results

Configuration Examples

Stand-alone Usage

.cnb.yml
main:
  pull_request.mergeable:
    - stages:
        - name: automerge
          type: git:auto-merge
          options:
            mergeType: merge

When a PR on the main branch triggers the pull_request.mergeable event, the PR will be automatically merged using the merge strategy.

Used with Target Branch `push` Event

.cnb.yml
main:
  push:
    - stages:
        - name: build
          script: npm run build
        - name: publish
          script: npm run publish
  pull_request.mergeable:
    - stages:
        - name: automerge
          type: git:auto-merge
          options:
            mergeType: merge

When a PR on the main branch triggers the pull_request.mergeable event, the PR will be automatically merged using the merge method.

After the merge, the last reviewer who approved the review will act as the trigger, initiating the push event on the target branch (main), and the declared build and publish processes will continue to execute.

Best Practices

Using `squash` Auto-Merge

Utilize squash merging to create only one commit node on the target branch for each PR and optionally delete the source branch if permissions allow.

.cnb.yml
main:
  review:
    - stages:
        - name: automerge
          type: git:auto-merge
          options:
            mergeType: squash
            removeSourceBranch: true

Automatically Selecting Merge Type with `auto`

Automatically determine the merge type based on whether multiple people are contributing (use merge) or if it's a single contributor (use squash).

.cnb.yml
main:
  review:
    - stages:
        - name: automerge
          type: git:auto-merge
          options:
            mergeType: auto

Establishing a Dedicated CR Group for Cross-Review Auto-Merge

Automatically merge after code review approval.
Include reviewer information in the commit message.

.cnb.yml
main:
  pull_request.mergeable:
    - stages:
        - name: Auto-Merge after CR Approval
          type: git:auto-merge
          options:
            mergeType: squash
            mergeCommitMessage: $CNB_LATEST_COMMIT_MESSAGE
          exports:
            reviewedBy: REVIEWED_BY

All Events

Work Mechanism

Check if the issue exists -> Check if it meets the when condition (optional) -> Check if it meets the lint condition (optional) -> Update issue status or labels

Issue Retrieval Method

1. When fromFile or fromText parameters are provided:

Retrieve and parse from the provided text file or text. fromFile takes precedence over fromText.

2. When neither fromFile nor fromText parameters are provided:

Issue-related events:
Retrieve the current Issue.
PR-related events:
Retrieve and parse from the commit logs of the PR's commits.
commit.add event:
Retrieve and parse from the commit logs of the newly added commits.
push event for non-new branches:
Retrieve and parse from the commit logs of the pushed commits.
Other cases:
Retrieve and parse from the commit log of the latest commit.

Tips

If you need to use this in a branch.delete event, since the branch has already been deleted and cannot be retrieved from the context, you must provide the parsing content using the fromText or fromFile parameter.

Retrieval Method: Extract the following two formats from the above text:

#IssueID: Represents an Issue in the current repository. For example, #123 refers to Issue ID 123 in the current repository.
groupName/repoName#IssueID: Represents a cross-repository (other repository) Issue. For example, test/test#123 refers to Issue ID 123 in the test/test repository.

Note: #123 or test/test#123 must be preceded by a space.

Including Issue in Commit Logs

When committing code, you can include the associated IssueID in the commit log, which can be automatically extracted when using the current built-in task to update the associated issue for updating labels and status.

It is recommended to include the IssueID in the body of the commit log. Here are two command-line methods:

Method 1: Use shift + enter for a new line, and it's recommended to add a blank line between the title and body.

git commit -m "fix(Cloud-Native Build): Fix an error

cnb/feedback#123"

Method 2: Using this method will create two new lines between the title and body.

git commit -m "fix(Cloud-Native Build): Fix an error" -m "cnb/feedback#123"

Parameters

fromText
fromFile
state
label
assignee
when
lint
defaultColor
prefix

fromText

Type: String
Required: false

Parses IssueId from the provided text.

If not specified, it automatically parses from the commit records in the context. You can specify a text containing IssueId references to declare the target, such as when used in conjunction with a changelog generation plugin to automatically extract IssueId from the changelog.

fromFile

type: String
required: false

Reads content from a text file and parses IssueId. This takes precedence over fromText.

When the content is too large, it is recommended to use this parameter to pass the content via a file to avoid exceeding limits.

state

type: IssueStateMap
required: false

Corresponds to the state attribute. When set to close, it can close the Issue.

label

type: UpdateLabel
required: false

Description of the operation on labels.

assignee

type: UpdateAssignee

lint

type: IssueUpdateStatus
required: false

Check if the Issue meets the conditions. If not met, an exception is thrown. Multiple conditions are connected by or, and when empty, no checks are performed.

defaultColor

type: String
required: false

Default color for added labels, effective only when the label.add parameter is provided.

prefix

type: String[]
required: false

The issue prefixes that need to be processed, for example, if close and closed is passed, it will handle all issues prefixed with close and closed. For instance, close #123 or closed #123 #456.

}

Permission Check

If the issue that needs to be updated belongs to the repository to which the pipeline belongs, and the event is not pull_request, pull_request.update, pull_request.approved, or pull_request.changes_requested, then the permission of the pipeline triggerer to modify the issue will not be checked.

Configuration Examples

After merging into main, update labels

.cnb.yml
main:
  push:
    - stages:
        - name: update issue
          type: git:issue-update
          options:
            # Remove the "In Progress" label and add the "Pre-release" label
            label:
              add: Pre-release
              remove: In Progress
            # Perform the above label operations only when there are "feature" or "bug" labels
            when:
              label:
                - feature
                - bug

When a tag is pushed, close the issue and update labels

.cnb.yml
$:
  tag_push:
    - stages:
        - name: release operation
          script: echo "Use release tasks instead of the current task"
        # Perform issue update operation after release operation
        - name: update issue
          type: git:issue-update
          options:
            # Close the issue
            state: close
            # You can specify prefixes for issues that need to be closed. If set, only those containing "close #123" or "closed #123" will be closed.
            # prefix:
            #   - close
            #   - closed
            # Remove the "Pre-release" label and add the "Released" label
            label:
              add: Released
              remove: Pre-release
            # Perform the above operations only when there are "feature" or "bug" labels
            when:
              label:
                - feature
                - bug

When tag is pushed, find IssueId included in the changes between the current tag and the previous tag, and add labels

Configuration Examples
Best Practices

Applicable Events

pull_request
pull_request.target
pull_request.update

Under pull_request and pull_request.update events, the trigger will check if the initiator has permission to operate on reviewers/assignees. This check is not performed under the pull_request.target event. For PRs submitted across repositories, there may be cases where the initiator lacks permission. In such cases, it is recommended to use the pull_request.target event.

How to Get PR ID

1. When fromFile or fromText parameters are provided:

Parse the PR from the provided text file or text. fromFile takes precedence over fromText.

2. When fromFile or fromText parameters are not provided:

PR-related events:
Parse from the commit logs of the PR's commits. Additionally, include the current PR.
commit.add event:
Parse from the commit logs of the newly added commits.
Non-new branch push event:
Parse from the commit logs of the current push.
Other cases:
Parse from the commit log of the latest commit.

Tips

If you need to use this in a branch.delete event, since the branch has been deleted and cannot be retrieved from the context, you must provide the content to parse using the fromText or fromFile parameters.

Parsing method: Extract the following two formats from the text:

PR-URL: <your-repo-slug>#<number>
PR-URL: #<number>

Where:

your-repo-slug is the repository path, e.g., cnbcool/cnb.
number is the PR number, found after the PR page URL.

To distinguish from an Issue, the prefix PR-URL: is required.

Note: Ensure there is a space before #123 or test/test#123.

Parameters

fromText

type: String
required: false

Parse the PR from the provided text.

If not declared, it will automatically parse from the commit logs in the context. You can specify a text containing a PR ID reference to declare the target, such as using it with a changelog generation plugin to automatically extract the PR ID from the changelog.

fromFile

type: String
required: false

Read and parse the PR from a text file. Takes precedence over fromText.

label

type: UpdateLabel
required: false

Labels to be added or removed.

title

type: String
required: false

The title of the PR.

defaultColor

type: String
required: false

The default color for the added label. This is only applicable when the label.add parameter is provided.

Output Results

{
    pullRequests // List of modified PRs
}

Permission Check

If the PRs to be updated belong to the pipeline's repository, and the events are not pull_request, pull_request.update, pull_request.approved, or pull_request.changes_requested, the pipeline triggerer's permissions to modify the PR will not be checked.

Configuration Examples

The following pipeline implements the following functionalities:

When the pull_request pipeline fails: Add the label To be modified.
When the pull_request pipeline succeeds: Add the label Pending review and remove the label To be modified.
When the pull_request.merged pipeline runs: Add the label To be released and remove the label Pending review.

.cnb.yml
main:
  pull_request:
    - stages:
        - name: check
          script: echo "do some check"
        - name: Add PR label - Pending review
          type: git:pr-update
          options:
            label:
              add:
                - Pending-review
              remove:
                - To-be-modified
      failStages:
        - name: Add PR label - To be modified
          type: git:pr-update
          options:
            label:
              add:
                - To-be-modified

  pull_request.merged:
    - stages:
        - name: check
          script: echo "do some check"
        - name: Add PR label - To be released
          type: git:pr-update
          options:
            label:
              add:
                - To-be-released
              remove:
                - Pending-review

Testing

Coverage

testing:coverage

Unit Test Coverage, calculates the coverage based on unit test result reports and reports badge data.

You can view the coverage badge data of the latest 100 commits by branch in the repository's Insights page in the form of charts.

Tips

For coverage data uploaded by pipelines triggered by events related to Pull Requests (except pull_request.merged), switch to the pull request view to see the unit test insights curve.

Applicable Events
Full Coverage
Incremental Coverage
Parameters
Output Results
Configuration Examples

Applicable Events

All Events

Full Coverage

Parsed from local coverage report files, currently recognizing the following report formats:

json(js) (recommended)
json-summary
lcov (recommended)
jacoco
golang

Incremental Coverage

Parameters

key
name
pattern
lines
diffLines
allowExts
lang
breakIfNoCoverage

key

type: String
required: false

Coverage data key values, used to distinguish between different types of coverage data, such as frontend, backend, etc.

name

type: String
required: false

Coverage data names, used for display in badges, correspond one-to-one with coverage data keys. When a key does not exist, the name will be ignored.

For example: key: frontend, name: frontend coverage

pattern

type: String
required: false

In Glob format, specifies the location of the coverage report file relative to the current working directory. If not provided, it will try to find the following files in the current directory (including subdirectories): coverage.json, jacoco*.xml, lcov.info,*.lcov.

lines

type: Number
required: false

Specifies the full coverage red line. If the full coverage percentage is less than this value, the workflow will be blocked from exiting the pipeline.

diffLines

type: Number
required: false

Specifies the incremental coverage red line. If the full coverage percentage is less than this value, the workflow will be blocked from exiting the pipeline. Events like pull_request, pull_request.update, pull_request.target support calculating incremental coverage results, while other events only calculate full coverage.

allowExts

type: String
required: false

Whitelist of code file types to be included in coverage calculation, separated by commas, e.g., .json, .ts, .js. If not provided, all files in the report will be included in the calculation.

lang

type: String
required: false

When the coverage report target format is golang, specify this parameter as go to avoid calculation errors. This parameter can be ignored in other cases.

breakIfNoCoverage

type: Boolean
required: false

Whether to throw an error and terminate the process if no coverage report file is found.

Output Results

{
  // Code line coverage, e.g., 100. Value is NA if calculation fails.
  "lines": 100,
  // Incremental code line coverage, e.g., 100. Value is NA if calculation fails.
  "diff_pct": 100
}

TAPD

When submitting code, you can add TAPD source code keywords in the commit message or PR description. The cloud-native build system will automatically recognize and associate commits, PRs, and TAPD work items.

In pipelines triggered by code pushes, PRs, and tags, you can update the information of TAPD-associated items through the following tasks.

Prerequisites

The TAPD feature must be enabled in the root organization.
The pipeline triggerer must have a bound TAPD account.

TAPD Association Item Filtering Rules

The pipeline will filter associated TAPD work items based on the following rules:

1. When the fromFile or fromText parameters are provided:

Parse the commit IDs from the provided text file or text, and query the associated TAPD work items.

The fromFile parameter takes precedence over fromText.

2. When neither the fromFile nor fromText parameters are provided:

PR-related events:
Query the TAPD work items associated with the commits and PR description of the PR.
commit.add event:
Query the TAPD work items associated with the newly added commits.
push event for non-new branches:
Retrieve the associated TAPD work items from the commit logs of all commits in this push.
Other cases:
Query the TAPD work items associated with the latest commit.

Through the above rules, ensure systematic and efficient association between code changes and TAPD work items.

TAPD Association Item Types
The type in the TAPD work item source code keyword is the work item type, such as: story, task, bug.

Note: The source code keyword for TAPD tasks may be either story or task. Please distinguish carefully.

npc

go

npc:go

Executes an AI coding agent task in a specified Docker image when an NPC role is mentioned in an Issue or PR comment. You can install CLI tools and Skills required by the NPC at runtime in the image, such as CNB Skill. For more NPC configuration, see NPC Events.

Applicable Events

issue.comment@npc, pull_request.comment@npc, api_trigger, crontab

Parameters

Warning

The following parameters only take effect in api_trigger and crontab events. No configuration is needed for other events.

role

type: String
required: true

NPC role name. It must be defined in the roles field of the NPC section in the .cnb/settings.yml file. See UI Customization(Open in new window) for reference.

systemPrompt

type: String
required: true

NPC system prompt.

userPrompt

type: String
required: true

NPC user input, mainly used for the user to describe tasks to the NPC.

Configuration Examples

.cnb.yml
$:
  issue.comment@npc:
    - docker:
        # Specify image containing CLI tools and Skills required by the NPC
        image: ${CNB_DOCKER_REGISTRY}/${CNB_NPC_SLUG_LOWERCASE}:latest
      stages:
        - name: npc go
          type: npc:go

# Build and push Docker image
main:
  push:
    - services:
        - docker
      stages:
        - name: Docker build
          script: docker build -t ${CNB_DOCKER_REGISTRY}/${CNB_REPO_SLUG_LOWERCASE}:latest .
        - name: Docker push
          script: docker push ${CNB_DOCKER_REGISTRY}/${CNB_REPO_SLUG_LOWERCASE}:latest

Install the Skills and CLI tools required by the NPC in the Dockerfile. The following example installs cnb-skill and cnb-cli.

Dockerfile
FROM node:22-bookworm-slim

RUN apt-get update \
    && apt-get install -y --no-install-recommends ca-certificates git git-lfs curl jq ripgrep \
    && rm -rf /var/lib/apt/lists/* \
    && git lfs install \
    && npm install -g @cnbcool/cnb-cli skills \
    && npx skills add https://cnb.cool/cnb/skills/cnb-skill.git -g -y

Skills are automatically loaded from the following directories: ~/.agents/skills, ~/.codebuddy/skills and their project-level counterparts: .agents/skills, .codebuddy/skills.

Project-level Skills take priority over user-level Skills. A project-level Skill with the same name will override its user-level counterpart.

The NPC role prompt is defined in the .cnb/settings.yml file. See NPC Events for details.
