We’re migrating our apps from Distillery to mix release. It has been going well so far, but one thing that has been confusing us is that files placed in
rel/overlays don’t seem to be copied to anywhere in the release (we also have the
:tar step in the release). The following is a minimum reproduction:
def project do [ # ... releases: [ demo: [ include_executables_for: [:unix], steps: [:assemble, :tar] ] ] ] end
We placed a
Dockerfile under the
But when I grep the whole folder after running
MIX_ENV=prod mix release, the
Dockerfile still only exists in one copy, in
rel/overlays, but not anywhere in the release itself.
demo-0.1.0.tar.gz also doesn’t contain this file anywhere.
We tried to manually specify `overlays: “some_other_dir” but it didn’t work either.
The Elixir version is 1.9.4
Did we do something wrong?
