连接容器失败

Question

I ran a command like this in a docker-in-docker (dind) scenario:

docker daemon --host=unix:///var/run/docker.sock --host=tcp://0.0.0.0:2375 --storage-driver=overlay

And I got this in the logs:

INFO[0000] libcontainerd: new containerd process, pid: 18
FATA[0000] Failed to connect to containerd. Please make sure containerd is installed in your PATH or you have specificed the correct address. Got error: write /proc/18/oom_score_adj: permission denied

Answer 1

Be sure to run the container in privileged mode.

docker run --privileged ...

This should fix the problem; you should now be able to install and run Docker inside this Docker image.
