# act_runner — Gitea Actions self-hosted runner
# Runs on arrsstack (10.0.0.104). Gitea is on a separate machine (10.0.0.102).
# Registers at instance level — services all repos.
#
# host mode: jobs run inside the act_runner container.
# docker and node binaries + their ARM64 shared libraries are mounted from
# arrsstack's host filesystem so workflow steps can call docker build/push etc.
#
# Setup:
#   1. Gitea → Site Administration → Actions → Runners → Create Runner → copy token
#   2. Add RUNNER_TOKEN to Portainer stack environment variables
#   3. Deploy stack
