我想知道是否有可能在runghcr.io/synesthesiam/homeassistant-satellite上使用的docker-compose中添加健康检查。特别是,有时容器停止工作,我可以在日志中看到以下内容:

字符串
我尝试添加以下内容,但不起作用:

healthcheck:
      test: ["CMD-SHELL", "docker logs homeassistant-satellite 2>&1 | grep -i 'ERROR' || exit 1"]
      interval: 1m # How often to run the check
      timeout: 10s # Maximum time allowed for the check
      retries: 1 # Number of failures before marking unhealthy
      # Add this line to trigger restarts on failures
      start_period: 60s # Delay before restarting after failure


你能给我指个方向吗?

kmpatx3s

kmpatx3s1#

命令在容器内执行。容器内是否有dockerdocker.sock是否已挂载?
你可以用一个进程来启动容器,该进程将日志写入文件。看看https://github.com/synesthesiam/homeassistant-satellite/blob/master/Dockerfile

command: bash -c "python -m homeassistant_satellite | tee /logfile"

字符串
然后检查日志文件是否有错误。我会截断日志文件,所以只考虑新行。

grep -qi 'ERROR' /logfile; ret=$((!$?)); truncate -s 0 /logfile; exit "$ret"
