new images fails with Permission denied

[yaitskov]

Hi,

I use mysql:5.6 image. Yesterday after rebuilding db image the container fails to start with error

docker logs bbaaf7335e96
/usr/local/bin/docker-entrypoint.sh: line 21: /dev/null: Permission denied

I use

docker --version
Docker version 1.11.1, build 5604cbe

I didn't updated docker but noticed that docker-entrypoint.sh is different from the working image.

docker inspect 64792228c966

What does your docker run look like?

[broth-eu]

I'm having the same issue with this image. It occurs with all mariadb images as well. However, other images (e.g. the one for Neo4j) work without any problems.
I simply try to start the container using following command: docker run mysql

[kowalk]

Same here:
mysql_1 | /usr/local/bin/docker-entrypoint.sh: line 21: /dev/null: Permission denied

[yosifkit]

Can you give any extra info? docker version, docker info, docker-compose.yml contents or docker run line?

I'm having the same problem.

@dcardosods, I would venture to guess that mysql is failing for you? Have you tried to tell it to run as a different user? Something like MariaDB/mariadb-docker#58 (comment)? So that it runs as the owner of the ./.data/db directory from the host that is shared through VirtualBox shared folders.
