Usage in Workspaces

1. Configure dotnet development environment in .cnb.yml

.cnb.yml

$: 
  vscode:
    - docker:
        image: mcr.microsoft.com/dotnet/sdk:9.0

2. Configure nuget repository address, username, and password

Replace <REPO_URL> with the Artifact Registry address, <TOKEN_NAME> with the credential name, <YOUR_TOKEN> with the credential

dotnet nuget add source <REPO_URL> --name <TOKEN_NAME> --username cnb --password <YOUR_TOKEN> --store-password-in-clear-text
dotnet pack xxx.csproj --configuration Release --output nupkgs
dotnet nuget push "nupkgs/*.nupkg" --source <TOKEN_NAME>

• Example: Add credential cnb-nuget-repo, build nuget artifact, and push it to CNB

dotnet nuget add source https://nuget.cnb.cool/cnb/nuget-repo/-/packages/v3/index.json --name cnb-nuget-repo --username cnb --password <YOUR_TOKEN> --store-password-in-clear-text
dotnet pack mynupkg.csproj --configuration Release --output nupkgs
dotnet nuget push "nupkgs/*.nupkg" --source cnb-nuget-repo

FAQ

Q1: Encountered 401 Forbidden error

Possible cause: Insufficient permissions for the credential.

Solution: Reconfigure the access token with the required permissions. Token acquisition: Personal Settings -> Access Tokens -> Add Access Token -> Select the appropriate permissions for the Artifact Registry.

Q2: Encountered 403 Forbidden error

Possible cause: Incorrect credential configuration.

Solution: Configure the correct access token for the Artifact Registry. Token acquisition: Personal Settings -> Access Tokens -> Add Access Token -> Select the appropriate permissions for the Artifact Registry.

Q3: Encountered 409 Forbidden error

Possible cause: Package already exists and overwriting is not allowed.

Solution: To overwrite the package, go to the corresponding Artifact Registry -> Artifact Registry Settings -> Policy Management -> Select "Allow Overwriting Existing Versions".

Q4: How to support HTTP

Possible cause: Client only supports HTTPS by default.

Solution:

Client/Tool	HTTP support
dotnet CLI	Specify --allow-insecure-connections when adding the repository credential
nuget.exe	Specify -AllowInsecureConnections when adding the repository credential
