Request for Examples of Using systemd in Docker Containers with AlmaLinux

Dear AlmaLinux Communities,

I hope this message finds you well.

I am currently working with Docker containers and am interested in running services using systemd inside containers, particularly when using AlmaLinux and Rocky Linux images. I have found useful examples for CentOS-based Docker images, specifically the official CentOS systemd Docker container available at https://hub.docker.com/r/centos/systemd/. This example demonstrates how to run services like httpd within a container using systemd.

However, I have not come across similar examples or documentation for AlmaLinux and Rocky Linux images.

For context, the CentOS-based example is as follows:

1. The base image centos/systemd is used.
2. Services, such as httpd, are installed and enabled through systemctl inside the container.
3. The container is then run with specific Docker flags to allow systemd to operate.

I would greatly appreciate it if you could provide:

1. Any similar official examples or best practices for using systemd within AlmaLinux or Rocky Linux Docker containers.
2. Guidance on how to properly set up systemd-based services within these images (e.g., enabling HTTPD, networking services, etc.).
3. Suggestions for Dockerfile configurations or Docker run commands that would facilitate running systemd inside these containers.

I understand that systemd might not always be directly supported in some containerized environments, but I am hoping the community could share some insights or recommendations on how to achieve this effectively with AlmaLinux and Rocky Linux.

Thank you in advance for your time and support. I look forward to your guidance.

Best regards,
