Full Description

tutum-centos

Simple CentOS docker image with SSH access

Usage

To create the image tutum/centos with one tag per CentOS release, execute the following commands on the tutum-ubuntu repository folder:

docker build -t tutum/centos:latest .
docker build -t tutum/centos:centos5 centos5
docker build -t tutum/centos:centos6 centos6
docker build -t tutum/centos:centos7 centos7

Running tutum/centos

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!

Setting a specific password for the root account

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

Adding SSH authorized keys

If you want to use your SSH key to login, you can use the AUTHORIZED_KEYS environment variable. You can add more than one public key separating them by ,:

docker run -d -p 2222:22 -e AUTHORIZED_KEYS="`cat ~/.ssh/id_rsa.pub`" tutum/centos
