Package: buildah
Severity: important
X-Debbugs-Cc: e...@sil.org
It looks like the version of buildah included in Debian (and Ubuntu) doesn't
support heredocs although this has been fixed for a while in upstream. It looks
like that patch got intentionally reverted in Debian.
This greatly reduces the compatibility with Docker as well as with Podman on
other systems.
To reproduce:
Create a `Dockerfile`:
```
FROM alpine
ARG FOO=bar
COPY <<-EOT /script.sh
echo "hello ${FOO}"
EOT
ENTRYPOINT ash /script.sh
```
and build with `buildah build -f Dockerfile`. This fails with:
```
$ buildah build -f Dockerfile
STEP 1/6: FROM alpine
STEP 2/6: ARG FOO=bar
STEP 3/6: COPY <<-EOT /script.sh
Error: building at STEP "COPY <<-EOT /script.sh": checking on sources under
"/tmp": copier: stat: "/<<-EOT": no such file or directory
```
