Error committing Oracle tablespace in Docker

Question

I tried to "docker commit" the tablespace I created on a container that is based on alexeiled's oracle xe 11g container.

But I got this error:

FATA[0027] Error response from daemon: ApplyLayer exit status 1 stdout:  stderr: write /u01/app/oracle/oradata/XE/usr.dbf: read-only file system

Why is it trying to write usr.dbf to a read-only filesystem?

Docker command: sudo docker commit d74005e729bd oracle-simou

Docker version: Docker version 1.5.0, build a8a31ef

Host OS: archlinux

sudo docker run -d -p 49160:22 -p 49161:1521 -p 49162:8080 alexeiled/docker-oracle-xe-11g — simou, Mar 11 '15 at 14:35
So you started the container and added a tablespace within it. After that, you tried to commit the changes into a new image? — Bohne, Mar 16 '15 at 12:52

Please ensure that you have enough free disk space for Docker container in docker graph, usually it's /var/lib/docker/graph.

If your /var space is limited, you can change docker root location by specifying -g option

-g, --graph="/var/lib/docker"          
Path to use as the root of the Docker runtime

I ended up using wnameless' container (wnameless/docker-oracle-xe-11g) and with your hint I had no problems commiting the tablespace. – simou May 26 '15 at 06:56
