# Wrapper to run a one-off `docker run` INSIDE the infinito host container
# (which already provides nested Docker-in-Docker). Used for inner-loop
# debugging where you need to spin up a sidecar image (e.g. the Playwright
# runner) against the same docker daemon the deployed stack lives on,
# without re-running an Ansible playbook.
#
# Required env:
#   IMAGE              Image reference passed to `docker run` (e.g. alpine,
#                      mcr.microsoft.com/playwright:v1.59.1-noble)
#
# Optional env:
#   cmd                Command to execute inside the sidecar container.
#                      When omitted, the image's default entrypoint runs.
#   INFINITO_RUN_FLAGS          Extra flags forwarded verbatim to `docker run`
#                      (e.g. "--env-file /tmp/x.env -v /tmp/y:/y -w /e2e").
#   INFINITO_DISTRO    arch|debian|ubuntu|fedora|centos — selects which
#                      infinito host container we exec into.
#   INFINITO_CONTAINER Optional explicit override of the host container name.
#
# Examples:
#   IMAGE=alpine make compose-inner-run
#   IMAGE=alpine cmd='env | grep PATH' make compose-inner-run
#   IMAGE=mcr.microsoft.com/playwright:v1.59.1-noble \
#     INFINITO_RUN_FLAGS='--env-file /tmp/test-e2e-playwright/web-app-friendica/.env \
#                -v /tmp/test-e2e-playwright/web-app-friendica:/e2e -w /e2e' \
#     cmd='npx playwright test --grep dashboard' \
#     make compose-inner-run
