# This Compose file provides the overrides needed to develop Labspace content.
#
# This variant will mount in the source content into the configurator, where it will then be
# copied into the volume that is shared with the rest of the labspace. This allows you to run through
# the lab, making changes to files, running startup scripts, and more without polluting the actual
# content. Compose Watch will monitor the content directory for changes and sync them into the
# workspace, which shares the volume with the interface.
#
# The CONTENT_PATH environment variable is being used here because we are unable to simply use
# a relative path (such as "./"). When running the Compose stack via a published OCI artifact,
# the working directory is not the same as the location of the Compose files, which is its cached
# location on the host filesystem. Therefore, the paths would not resolve correctly.

# This Compose file extends the default Labspace setup by adding the following elements:
#
# - A Traefik reverse proxy to route traffic to Gitea and k3s
# - A Gitea server for Git hosting and CI/CD
# - A Gitea self-hosted runner for executing CI jobs
# - A k3s Kubernetes cluster
#
# This provides a "SDLC-in-a-box" environment for end-to-end labs.
#
# Additional documentation is found in the docs/sdlc-labspace.md file.
