Overview

This Docker container makes it easy to get an instance of SSHD up and running with RHEL.

Based on Official RHEL Docker Image with some minor hack:

  • Packaging by Packer Docker builder and Ansible provisioner in single layer
  • Handle ENTRYPOINT with catatonit
  • Handle CMD with SSHD

Quick Start

Start SSHD:

# Pull latest image
docker pull alvistack/rhel-8

# Run as detach
docker run \
    -itd \
    --name rhel \
    --publish 2222:22 \
    alvistack/rhel-8

Success. SSHD is now available on port 2222.

Because this container DIDN'T handle the generation of root password, so you should set it up manually with pwgen by:

# Generate password with pwgen
PASSWORD=$(docker exec -i centos pwgen -cnyB1); echo $PASSWORD

# Inject the generated password
echo "root:$PASSWORD" | docker exec -i centos chpasswd

Alternatively, you could inject your own SSH public key into container's authorized_keys by:

# Inject your own SSH public key
(docker exec -i centos sh -c "cat >> /root/.ssh/authorized_keys") < ~/.ssh/id_rsa.pub

Now you could SSH to it as normal:

ssh root@localhost -p 2222
