Goal: determine whether rootless Podman containers started in the same pod receive separate user namespaces or share a single namespace, because UID mapping controls file ownership and access permissions. Podman's rootless mode depends on user namespaces, but documentation does not consistently specify whether each container in a pod receives its own UID ran
Determine whether Podman should enable journald logging by default for rootless containers to improve integration with the systemd journal. Rootless containers run without elevated privileges, which may prevent them from writing to the system journal; relying on a manual --log-driver=journald flag can lead to inconsistent logging, while preserving the existi
Goal Expose a container service on a host port 80 while running Podman in rootless mode on RHEL. Current Constraints Rootless containers run in a user namespace; kernel capability checks still apply. The boundary is defined by net.ipv4.ip_unprivileged_port_start (1024 by default). The value cannot be overridden per container. Podman’s --privileged flag in ro
Goal Determine the least‑privilege approach for handling authentication in rootless Podman when credentials become stale. Constraints Rootless mode relies on user namespaces and stores credentials in ~/.config/containers/auth.json . Credential helpers can offload tokens to system keyrings, but their integration with rootless authentication is unclear. Expire
