Container stoppen
docker.io stop cc65f386f2d5

Docker Container finden
docker.io search gitlab
Benutzung
docker.io attach cc65f386f2d5
Special Gitlab
docker run --name=mysql-gitlab -d \
--env='DB_NAME=gitlabhq_production' \
--env='DB_USER=gitlab' --env='DB_PASS=password' \
--volume=/srv/docker/gitlab/mysql:/var/lib/mysql \
sameersbn/mysql:latest
The above command will create a database named gitlabhq_production and also create a user named gitlab with the password password with full/remote access to the gitlabhq_production database.
docker run --name=gitlab -d --link=mysql-gitlab:mysql \
--volume=/srv/docker/gitlab/gitlab:/home/git/data \
sameersbn/gitlab:7.11.4-1
Here the image will also automatically fetch the DB_NAME, DB_USER and DB_PASS variables from the mysql container as they are specified in the docker run command for the mysql container. This is made possible using the magic of docker links.
