Note: If docker daemon does not start at boot, you might want to enable the docker service
|
1
|
systemctl enabledocker.service |
Here are the steps.
Create the file /etc/systemd/system/docker_demo_container.service

Now I can start the service
|
1
|
systemctl start docker_demo_container |
And I can enable the service so it is executed at boot
|
1
|
systemctl enabledocker_demo_container |
That’s it, my container is started at boot.

#!/bin/bash
exec "$@"
and I have the following in my Dockerfile:
ADD entrypoint.sh /entrypoint.sh
RUN chmod +x /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]
