[duplicate] Plugins/docker unable to access docker socket

Drone Support
1

Hello,

I recently scaled-up my kube cluster and removed my old small nodes (this was a bad idea without testing Drone first, but let’s not go there for a moment)

Previously I had been using the plugins/docker image to build images and it worked flawlessly. However after I upgraded, now I’m getting the following error on all builds using plugins/docker:

  • /usr/local/bin/dockerd --data-root /var/lib/docker --host=unix:///var/run/docker.sock

  • /usr/local/bin/docker version
    Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

It was my understanding that Drone runs the plugins/docker image as privileged by default, and thus I shouldn’t be having this issue. I’m sure there’s a simple answer but I can’t find it after many hours of googling and I’m starting to get stressed out. Can you help me figure out why this is happening? I haven’t changed my pipeline config at all.

For reference, here’s my yaml:
