Container builds incompatible with podman

[gmemstr]

What versions & operating system are you using?

wrangler 4.21.2

Please provide a link to a minimal reproduction

https://github.com/cloudflare/templates/tree/main/containers-template

Describe the Bug

When attempting to deploy a container with podman rather than Docker, it fails to build as podman does not have the --provenance flag.

It appears that the flag is set to false anyways (

workers-sdk/packages/containers-shared/src/build.ts

Line 17 in 2bdc3bb

"--provenance=false",

), so I wonder if either that flag can be dropped (I am not sure why it's set to false in the first place), or just drop it if podman is detected.

Please provide any relevant error logs

Building image hello-containers:0d302a66
Error: unknown flag: --provenance
See 'podman build --help'

Getting the same issue, our org can't use docker because of the change in license - requires a paid subscription.

workaround for now:

mkdir -p ~/bin && cat <<'EOF' > ~/bin/docker
#!/bin/bash
# Shim to replace Docker CLI with Podman and strip unsupported flags
ARGS=()
for arg in "$@"; do
  if [[ "$arg" != --provenance* ]]; then
    ARGS+=("$arg")
  fi
done
exec podman "${ARGS[@]}"
EOF
chmod +x ~/bin/docker && grep -q 'WRANGLER_DOCKER_BIN' ~/.zshrc || echo 'export PATH="$HOME/bin:$PATH"' >> ~/.zshrc && echo 'export WRANGLER_DOCKER_BIN=docker' >> ~/.zshrc && echo "export WRANGLER_DOCKER_HOST=unix://$(podman info --format '{{.Host.RemoteSocket.Path}}')" >> ~/.zshrc && source ~/.zshrc

BUT.. it doesnt help me because docker.com (where pulling image from) is blocked on our network, guessing other orgs would have the same:

production.cloudflare.docker.com

why not just pre-build your image using "podman build" then push that image directly to registry.cloudflare using method below?
https://developers.cloudflare.com/containers/image-management/#using-pre-built-container-images
you can refer that image in wrnagler.jsonc
