Unable to connect to docker daemon on GitLab worker
Starting from yesterday we started to observe:
“Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?” error.
We haven’t touched anything around setup (uploaded below)
I have tried to remove the old docker installation and install it again but every time when “docker” command is invoked it states that daemon is not running,
Here is the error:
$ docker version
Client: Docker Engine - Community
Version: 20.10.7
API version: 1.41
Go version: go1.13.15
Git commit: f0df350

OS/Arch: linux/amd64
Context: default
Experimental: true
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
gitlab-ci.yaml
- apt-get -yqq update
- apt-get -yqq install apt-transport-https ca-certificates curl gnupg2 software-properties-common
- curl -fsSL https://download.docker.com/linux/debian/gpg | apt-key add -
- curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
- add-apt-repository “deb [arch=amd64] Index of linux/debian/ $(lsb_release -cs) stable”
- echo “deb https://apt.kubernetes.io/ kubernetes-xenial main” | tee -a /etc/apt/sources.list.d/kubernetes.list
- apt-get update -yqq
- apt-get -yqq install docker-ce
- apt-get update -yqq
- service docker start
- docker version
Docker version has started to fail as well as each command that uses docker as keyword.
We are using Debian for workers and workers are provided from GitLab.
P.S. The same question I’ve posted in StackOverflow with a bit more details:
Thanks in advance!
