- Containers are the standard for application deployment, with Kubernetes often used for large-scale orchestration.
- Podman with systemd integration offers a simpler, secure alternative for single-host or small-scale deployments.
- Podman's advantages include daemonless architecture, rootless containers, and OCI compliance.
- Quadlets provide declarative configuration and native service management with systemd.
- Network segmentation enhances security by isolating frontend and backend traffic.
- The example deployment includes Forgejo, PostgreSQL, and Traefik for a self-hosted Git service.
- Podman secrets ensure secure credential storage without hardcoding passwords.
- Quadlet files define container configurations with auto-update capabilities.
- Traefik handles TLS termination and routing with dynamic configuration via Docker provider labels.
- Systemd manages container lifecycle, enabling familiar service commands and automatic updates.
- SELinux integration and resource limits enhance security and performance.
- Health checks and monitoring tools like journald provide observability.
- This approach is ideal for self-hosted services, development environments, and simpler operational models.
- Security layers include network segmentation, rootless containers, and automatic updates.
- The setup is scalable into Red Hat's broader container ecosystem, including OpenShift and Fedora CoreOS.
