GitHub Container Registry
Pros
- + Free storage and bandwidth for public images with anonymous pulls — strongest OSS distribution offer
- + Images live with the code: one account, one permission model, GITHUB_TOKEN in Actions
- + OCI-compliant (Docker V2 manifests, foreign layers), internal visibility and fine-grained package permissions
- + Container image storage currently free even for private images, with a one-month notice policy before changes
- + Spending limits available to cap overage; metered billing beyond plan quotas
Cons
- - Private plan quotas are small (500 MB on Free) and shared with GitHub Actions artifacts
- - Free private container storage is a policy, not a contract — changeable with one month's notice
- - No published SLA or regional placement for ghcr.io
- - Retention and promotion tooling lag purpose-built registries like Harbor or Artifactory
Podman
Pros
- + Rootless by default — containers run without root, cutting the blast radius of a container escape
- + Daemonless architecture removes the privileged Docker socket and the daemon single point of failure
- + Docker CLI and Docker API compatibility keeps migration cheap for most workflows
- + Free under Apache 2.0 with CNCF governance — no licensing terms to audit
- + Quadlet/systemd integration gives clean boot and restart semantics for server workloads
Cons
- - Compose workflows are the weak spot — podman-compose is third-party and not always drop-in
- - Thinner third-party ecosystem; plenty of tooling still hardcodes Docker
- - macOS and Windows support runs through a VM and trails Docker Desktop on polish
- - Rootless networking and user-namespace edge cases need real investigation per workload
