Docker Engine 26 + RHEL 9: Supported; Podman Is the RHEL Default
Docker Engine 26+RHEL 9
Docker Engine 26 is available for RHEL 9 via Docker's official repository. RHEL 9 defaults to Podman and Buildah — Docker Engine is supported but not Red Hat's recommended approach for enterprise RHEL deployments. For development and CI on RHEL 9, Docker Engine works correctly.
Workarounds & Fixes
Install via Docker repo: https://docs.docker.com/engine/install/rhel/
Alternative: use Podman with `podman-docker` compatibility shim
