v0.3.13 switched ENTRYPOINT to ["webclaw"] to make `docker run IMAGE https://example.com` work. That broke a different use case: downstream Dockerfiles that `FROM ghcr.io/0xmassi/webclaw` and set their own CMD ["./setup.sh"] — the child's ./setup.sh becomes arg to webclaw, which tries to fetch it as a URL and fails: fetch error: request failed: error sending request for uri (https://./setup.sh): client error (Connect) Both Dockerfile and Dockerfile.ci now use docker-entrypoint.sh which: - forwards flags (-*) and URLs (http://, https://) to `webclaw` - exec's anything else directly Test matrix (all pass locally): docker run IMAGE https://example.com → webclaw scrape ok docker run IMAGE --help → webclaw --help ok docker run IMAGE → default CMD, --help docker run IMAGE bash → bash runs FROM IMAGE + CMD ["./setup.sh"] → setup.sh runs, webclaw available Default CMD is ["webclaw", "--help"] so bare `docker run IMAGE` still prints help.

# Behaves like the real binary when the first arg looks like a webclaw arg
|
|
# (URL or flag), so `docker run ghcr.io/0xmassi/webclaw https://example.com`
|
|
# still works. But gets out of the way when the first arg looks like a
|
|
# different command (e.g. `./setup.sh`, `bash`, `sh -c ...`), so this image
|
|
# can be used as a FROM base in downstream Dockerfiles with a custom CMD.
|
|
#
|
|
# Test matrix:
|
|
# docker run IMAGE https://example.com → webclaw https://example.com
|
|
# docker run IMAGE --help → webclaw --help
|
|
# docker run IMAGE --file page.html → webclaw --file page.html
|
|
# docker run IMAGE --stdin < page.html → webclaw --stdin
|
|
# docker run IMAGE bash → bash
|
|
# docker run IMAGE ./setup.sh → ./setup.sh
|
|
# docker run IMAGE → webclaw --help (default CMD)
|
|
#
|
|
# Root cause fixed: v0.3.13 switched CMD→ENTRYPOINT to make the first use
|
|
# case work, which trapped the last four. This shim restores all of them.
