CentOS (from Community Enterprise Operating System) was a Linux distribution that provided a free, community-supported computing platform functionally compatible with its upstream source, Red Hat Enterprise Linux (RHEL). In January 2014, CentOS announced the official joining with Red Hat while staying independent from RHEL, under a new CentOS governing board.

This Docker container makes it easy to get an instance of SSHD up and running with CentOS.
Based on Official CentOS Docker Image with some minor hack:
- Packaging by Packer Docker builder and Ansible provisioner in single layer
- Handle
ENTRYPOINTwith catatonit - Handle
CMDwith SSHD
Start SSHD:
# Pull latest image
docker pull alvistack/centos-10-stream
# Run as detach
docker run \
-itd \
--name centos \
--publish 2222:22 \
alvistack/centos-10-stream
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
Release tags could be find from GitHub Release of this repository. Thus using these tags will ensure you are running the most up to date stable version of this image.
Version tags ended with .0.0 are rolling release rebuild by GitLab
pipeline in
weekly basis. Thus using these tags will ensure you are running the
latest packages provided by the base image project.
