How to grant permission to docker user write on /var/? - docker

Question

I'm trying to run confluence image on a docker container. This behavior is Intermittent - most of the time I can't run it, but at sometimes I can.
After downloading the image I run these commands in order put confluence online:
sudo chown -R daemon /data/confluence
sudo chown -R daemon /var/atlassian/application-data/confluence
docker run -v /data/your-confluence-home:/var/atlassian/application-data/confluence --name="confluence" -d -p 8090:8090 -p 8091:8091 atlassian/confluence-server
But then, I get this error on docker logs confluence
If you encounter issues starting up Confluence, please see the Installation guide at http://confluence.atlassian.com/display/DOC/Confluence+Installation+Guide

What am I doing wrong?

Answer 1

Have you tried via named volume (if using a docker version >= 1.9)?
$ sudo docker volume create --name confluenceVolume
$ sudo docker run -v confluenceVolume:/var/atlassian/application-data/confluence --name="confluence" -d -p 8090:8090 -p 8091:8091 atlassian/confluence-server

Answer 2

Add ENTRYPOINT script and use it. Example - https://github.com/AfsmNGhr/dockemacs/blob/master/Dockerfile#L34. See also - http://www.johnzaccone.io/entrypoint-vs-cmd-back-to-basics/.
