Summary

  • Add 2G swap on runner to prevent OOM crashes
  • Limit job container memory to 1536MB
  • Restrict runner concurrency to 1 job at a time
  • Disable cache to avoid Docker network connectivity issues (ETIMEDOUT 172.17.0.2)
  • Configure job containers with --add-host for private network gitea resolution

Test plan

  • Runner survives Go builds that previously OOM-killed the server
  • Verify swap is active after fresh provision (swapon --show)
  • Confirm job containers respect memory limit
