I'm working through the docker installation guide. Running CentOS 7. I ran:
curl -sSL https://get.docker.com/ | sh
warning: /var/cache/yum/x86_64/7/docker-main-repo/packages/docker-engine-1.8.2-1.el7.centos.x86_64.rpm: Header V4 RSA/SHA1 Signature, key ID XXXXXX: NOKEY Public key for docker-engine-1.8.2-1.el7.centos.x86_64.rpm is not installed. Importing GPG key
There's a little more after that about Userid, Fingerprint, from.
Next I ran:
sudo service docker start
Starting docker (via systemctl): Job for docker.service failed. See 'systemctl status docker.service' and 'journalctl -xn' for details. [FAILED]
I don't know what this message is referring to. How can I fix this?
systemctl status docker.service result:
docker.service timed out. Terminating. Failed to start docker application container engine Unit docker.service entered failed state
