To create the image centos7_sshd
, execute the following commands on the centos7_sshd
repository folder:
docker build -t centos7_sshd .
Run a container from the image you created earlier:
docker run -d centos7_sshd
The first time that you run your container, a random password will be generated
for user centos
. To get the password, check the logs of the container by running:
docker logs <CONTAINER_ID>
You will see an output like the following:
=> no authorized keys provided
=> Setting a random password to the centos user
=> Done!
========================================================================
You can now connect to this CentOS container via SSH using password:
ssh -p <port> centos@172.17.0.3
and enter the 'centos' password 'WlDtTZKCT5' when prompted
Please remember to change the above password as soon as possible!
========================================================================
In this case, WlDtTZKCT5
is the password allocated to the centos
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 -e ROOT_PASS="mypass" centos7_sshd
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 -e AUTHORIZED_KEYS="`cat ~/.ssh/id_rsa.pub`" centos7_sshd
