CentOS docker image with SSH access along with Puppet Client
To create the image tutum/centos with one tag per CentOS release, execute the following commands on the tutum-ubuntu repository folder:
git checkout master
docker build -t tutum/centos:latest .
git checkout centos5
docker build -t tutum/centos:centos5 .
git checkout centos6
docker build -t tutum/centos:centos6 .
git checkout centos7
docker build -t tutum/centos:centos7 .
Run a container from the image you created earlier binding it to port 2222 in all interfaces:
sudo docker run -d -p 0.0.0.0:2222:22 tutum/centos
The first time that you run your container, a random password will be generated
for user root. To get the password, check the logs of the container by running:
docker logs <CONTAINER_ID>
You will see an output like the following:
========================================================================
You can now connect to this CentOS container via SSH using:
ssh -p <port> root@<host>
and enter the root password 'U0iSGVUCr7W3' when prompted
Please remember to change the above password as soon as possible!
========================================================================
In this case, U0iSGVUCr7W3 is the password allocated to the root user.
Done!
If you want to use a preset password instead of a random generated one, you can
set the environment variable ROOT_PASS to your specific password when running the container:
docker run -d -p 0.0.0.0:2222:22 -e ROOT_PASS="mypass" tutum/centos
