# Replaces the image's own /etc/s6/act_runner/run. Two waits, both of which the
|
|
# stock script gets wrong for this deployment.
|
|
#
|
|
# 1. The nested Docker daemon. Upstream waits for it through s6's readiness
|
|
# notification. On a cold start with a warm image store dockerd takes longer
|
|
# than s6-notifyoncheck's window, the notification never arrives, s6 marks
|
|
# the service permanently failed, and act_runner sits blocked in
|
|
# `s6-svwait -U` for two to four minutes before s6 gives up and lets it past
|
|
# anyway. The runner shows "offline" in the forge for that whole time and
|
|
# picks up no jobs. Asking the daemon directly is the same wait without the
|
|
# guesswork.
|
|
#
|
|
# 2. The registration token. It is minted by an init step that runs after the
|
|
# stack is up, so on a first install it does not exist yet when this
|
|
# container starts — and the stock entrypoint reads the token file exactly
|
|
# once, before its retry loop, so a token that arrives late is never seen.
