Drone gcr plugin not working

Drone Support
1

We are running drone 1.6.5 on GKE cluster and trying to use gcr plugin but there are some issues.
On the first add command in the Dockerfile it fails with error:
rpc error: code = Unknown desc = Error: No such container: 2695c06191d6f47ae8a8565ae7abfaa2e3ade5d439a5c11541e81d071af663ce

  • name: build_lein_deps_saver
    image: plugins/gcr
    settings:
    repo: xxxx/lein_deps_saver

one thing that jumps out is you are mounting the host socket …

this plugin is meant to run docker-in-docker for isolation and circumventing the isolation by mounting the host machine socket can cause race conditions. For example the plugin runs a docker prune that, when mounting the host machine socket, will clear your entire host machine cache which can be problematic if other processes are relying on objects in the cache. If two instances of this plugin run at the same time with the host socket mounted they will clash with one another.
