Here's what went wrong:

The problem here is that the docker_logs source inside a container doesn't have permissions to read the Docker/Containerd socket or use the daemon API. You need to run Docker something like so:

docker run                                                                                                                                               
  -v ~/vector.toml:/etc/vector/vector.toml:ro \
  -v /run/containerd/containerd.sock:/run/containerd/containerd.sock \
  -e DOCKER_HOST="unix:///run/containerd/containerd.sock" \
  -p 8383:8383 \
  timberio/vector:0.11.X-alpine

This works for my (ubuntu vm):

docker run -d \
    -v ~/vector.toml:/etc/vector/vector.toml:ro \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -e DOCKER_HOST="unix:///var/run/docker.sock" \
    -p 8383:8383 timberio/vector:0.13.X-debian

Try docker.sock vs containerd.sock

Thanks JoseIbanez. Your snippet works for me. Ubuntu 20.04.

Closing since the socket needs to be mounted, as noted above, for the docker_logs source to work in the container.

so, vector does not support containerd.sock？ if runtime is containerd not docker
