Job for docker.service failed because the control process exited with error code

So I installed docker engine on RHEL 7

Now when I do a 

service docker start

I get the following error:

Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

and when I go to "systemctl status docker.service" and "journalctl -xe" I get:

I tried to search solution for this but could not find any.

I got this error after changing the docker config file:

/etc/docker/daemon.json

and I found the json I typed was in wrong format, after correcting it, the problem was solved.

I came across same issue in my Linux VM(virtual machine). System details : ubuntu 18.04 I had to just delete my daemon.json and then do a service docker start this worked for me.

Note: I had put insecure registry in my daemon.json file and i didn't want that as well hence i deleted it. I don't know it's usage though.

Check your OS logs files for warning or error messages.
Probably you have made a mistake in the config files of docker and when the service starts it gets an error.

The log's location depends on your OS. On Linux system logs are often in:

  • /var/log/daemon.log
  • /var/log/docker
  • /var/log/messages
  • /var/log/syslog
  • /var/log/upstart/docker.log

Some useful linux console commands to inspect docker logs:

  • sudo systemctl status docker.service
  • sudo journalctl -fu docker.service
  • cat /var/log/daemon.log | grep docker
  • cat /var/log/messages | grep docker

If you are using Windows this article might be helpful
Here are more details

There are many reasons for docker service failing to run. One of them that I encountered is using single quotes instead of double quotes for the key value pairs in the json file.

It fails

sudo cat > /etc/docker/daemon.json << '_EOF'
{
    'registry-mirrors': ['https://docker.io'] 
}
_EOF

It works!

sudo cat > /etc/docker/daemon.json << '_EOF'
{
    "registry-mirrors": ["https://docker.io"] 
}
_EOF

Just Remove Docker Lib and restart it again with:

sudo rm -rf  /var/lib/docker

then

sudo systemctl enable docker
sudo systemctl start docker

Fixing the Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details. problem, for me this worked:

  • create daemon.json in /etc/docker/

  • put this in it:

    {
    "exec-root": "/path/to/docker/run",
    "storage-driver": "overlay",
    "graph": "/path/to/docker/lib"
    }

  • then try: docker daemon
  • reboot
  • docker run hello-world should succeed now

What version of Docker do you use? If you are not locked to the elder one, consider use of the most recent version (currently it's 1.12). Here's my startup options (Debian 8, /etc/systemd/system/docker.service): 

[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network.target docker.socket
Requires=docker.socket

[Service]
Type=notify
ExecStart=/usr/bin/docker daemon -H fd:// --dns=10.240.116.7 --dns 8.8.8.8  --bip=172.17.42.1/24
MountFlags=slave
LimitNOFILE=1048576
LimitNPROC=1048576
LimitCORE=infinity
TimeoutStartSec=0

[Install]
WantedBy=multi-user.target

Also try to start Docker in debug mode (-D) without systemd, just like if it was a common program. This will help to find out why daemon doesn't start.
