Static Linux Binary Build

The repository includes a GitHub Action (.github/workflows/build-linux-binary.yml) that automatically builds a static Linux binary when a version tag is pushed. This action:

• Purpose: Creates a completely static Linux binary using Alpine Linux for maximum portability
• Use Cases:
  • Provides an easy-to-use binary for Linux users without Crystal dependencies
  • Serves as a dependency for the Build CLI CNB Buildpack
• Trigger: Automatically runs when pushing tags like v1.1.6
• Build Process: Uses Docker with Alpine Linux base image to create a fully static binary with all dependencies compiled in
• Output: Releases a bld-linux-amd64.zip file containing the static binary

To trigger a new release:

git tag v1.1.7
git push origin v1.1.7

The action will create a GitHub release with the Linux binary attached, which can be downloaded and used on any Linux AMD64 system without requiring any runtime dependencies.

Using a Custom API URL

You can specify a custom API endpoint for the CLI by setting the BUILD_API_URL environment variable. This is useful for development or testing against a local or alternative Build API instance.

The URL should include the scheme (http or https) and the port if necessary.

Example:

To run the CLI against a local server running on http://localhost:3000:

BUILD_API_URL='http://localhost:3000' bld login

When BUILD_API_URL is set, the CLI will direct all API requests to this URL, and it will store a separate entry in your .netrc file for this custom host, ensuring your regular Build credentials are not overwritten.

If BUILD_API_URL is not set, the CLI defaults to https://app.build.io.
