Cannot connect to the Docker daemon
We are using gitlab-ci-mutirunner with amazonec2 machine driver. Everything worked great until a few days ago. I know that docker-machine installs the last version docker-engine when creating instances, Is there something wrong with the last docker version?
The build stage just never connects to the runner and gitlab-ci-multi-runner keeps on launching runners to address the stage...
This is the log from the gitlab multirunner:
