Documented steps
Pull an image with podman pull quay.io/org/app:latest; the docker transport is the default and you can pull by digest with image@sha256:...
Authenticate first with podman login <registry>; credentials are stored in the containers auth.json authfile (falling back to the docker config json).
Push a locally built image with podman push localhost/app:1.0 quay.io/org/app:1.0, ensuring the destination has a registry prefix.
Control pull behavior with --policy always, missing, never, or newer; the latest tag is assumed when omitted.
Write the pushed digest to a file with --digestfile and set compression with --compression-format gzip or zstd.
Known gotchas
Short-name references such as podman pull alpine trigger registry resolution and an interactive prompt on a tty; unqualified short names risk squatted registry namespaces, so prefer fully-qualified references.
Remote clients (macOS/Windows excluding WSL2) only support the docker transport.
The authfile defaults to ${XDG_RUNTIME_DIR}/containers/auth.json on Linux; set REGISTRY_AUTH_FILE to override.
--disable-content-trust is a no-op kept for docker compatibility only; pull and push retry defaults to 3 attempts with exponential backoff.
Push defaults to gzip compression; the zstd:chunked format is incompatible with image encryption and falls back to zstd with a warning.
