I got an home server that is running docker for all my self hosted apps. But sometimes I accidentally trigger Earlyoom by remotely starting expensive docker builds, which kill docker.

I don’t have access to my server outside of my home network, so I can’t manually restart docker in those situations.

What would be the best way to restart it automatically? I don’t mind doing a full system restart if needed

    The other person may have responded with a fair amount of hostility, but they’re absolutely correct. I run Kubernetes clusters hosting millions of containers across hundreds of thousands of VMs at my job, and OOMKills are just a fact of life. Apps will leak memory, and you’re powerless to fix it unless you’re willing to debug the app and fix the leak. It’s better for the container to run out of memory and trigger a cgroup-scoped OOM kill. A system-wide OOM kill will murder the things you love, shit in your hat, and lick your face like David Tennant licked Krysten Ritter.

      Oh that’s not a problem to let a container get killed. It’s perfectly fine. What I want is just not crippling my whole server because one container did a funny.

      If it keeps docker and the portainer VM I’ll be 100% ok, because I can just restart it. I don’t want to have remote access to my server outside of my home for security reasons, so this is just the bare minimum

        What are your security concerns?
