SUMMARY

GOAL: I just want to start a container to be in macvlan network which i have already configured on my host.
I tried setting up DOCKER_HOST to some suggested values online but didnt work.
I AM RUNNING EVERYTHING LOCALLY
issue: Everything was working fine untill i added these lines in my roles/base/tasks/main.yml file. Now the ansible-container build fails...

• name: Add a container to a network, leaving existing containers connected
  docker_network:
  name: ocs_network
  #connected:

  - container_a

  appends: yes

STEPS TO REPRODUCE

root@nabeel-pc:/home/nabeel/Desktop/node5may# ps -aux | grep docker
root     13841  4.5  1.0 657476 83144 ?        Ssl  12:07   0:26 /usr/bin/dockerd -H fd:// -H unix:///var/run/docker.sock -H tcp://localhost:2375
root     13848  0.3  0.3 680600 23840 ?        Ssl  12:07   0:02 docker-containerd --config /var/run/docker/containerd/containerd.toml


===========================

Also the contents of my etc/docker/daemon.json file 

{

  "experimental": true

}

{
  "hosts": ["fd://", "unix:///var/run/docker.sock" ,"tcp://localhost:2375"]
}

I am running into the same issue. Any help appreciated ! https://stackoverflow.com/questions/51407444/ansible-container-docker-errors-dockerexception-error-while-fetching-server-api

That's quite confusing

You are adding that in the role for the container build, which looks erroneous

name: Add a container to a network, leaving existing containers connected
docker_network:
name: ocs_network

You should try whether the Docker daemon is really started.

For example with

$ sudo systemctl status docker

In my case Docker setup was broken in general (and therefore not related to ansible)

uggg can't believe this was my problem. Ansible seems to bomb out with a completely misleading error... but still i should have ensured docker was running!
