Paketo Buildpack for Rackup

gcr.io/paketo-buildpacks/rackup

The Rackup CNB sets the start command for a given rack-compliant ruby application.

Integration

This CNB writes a start command, so there's currently no scenario we can imagine that you would need to require it as dependency. If a user likes to include some other functionality, it can be done independent of the Rackup CNB without requiring a dependency of it.

To package this buildpack for consumption:

$ ./scripts/package.sh

This builds the buildpack's source using GOOS=linux by default. You can supply another value as the first argument to package.sh.

buildpack.yml Configurations

There are no extra configurations for this buildpack based on buildpack.yml.

Logging Configurations

To configure the level of log output from the buildpack itself, set the $BP_LOG_LEVEL environment variable at build time either directly (ex. pack build my-app --env BP_LOG_LEVEL=DEBUG) or through a project.toml file If no value is set, the default value of INFO will be used.

The options for this setting are:

• INFO: (Default) log information about the progress of the build process
• DEBUG: log debugging information about the progress of the build process

$BP_LOG_LEVEL="DEBUG"
