Documented steps
Author a Containerfile (or Dockerfile) in a build directory.
Run podman build -t myimage:latest . from that directory; an image name without a registry is stored locally under a localhost-style reference.
Point at a non-standard filename with -f and control the context (defaults to the Containerfile's parent directory).
For multi-stage builds select the desired stage with --target <stageName>.
For multi-architecture output pass --platform linux/amd64,linux/arm64 combined with --manifest <name> (multiple platforms require a manifest list instead of a single -t) and ensure emulation such as qemu-user-static for RUN steps.
Known gotchas
podman build is implemented with Buildah code; intermediate image caching (--layers) is on by default, disable with --no-cache. If a build crashes, leftover Buildah containers may remain — check podman ps --all --external.
The OCI image format is the default; produce Docker schema2 with --format docker or the BUILDAH_FORMAT environment variable.
Only files named exactly Containerfile or Dockerfile are auto-recognized; any other name requires -f.
--cache-from and --cache-to (remote cache) are ignored unless --layers is enabled.
podman buildx build is an alias of podman build for scripting compatibility, but not all buildx features are available.
