# Container image


## Chatbot release

The [chatbot containerfile](../../containers/chatbot.containerfile) intend to
be the smaller possible in order to ease and reduce the storage needed in
registries.

In order to provide a minimal image, the rust-alpine container image is used.
This image uses the `x86_64-unknown-linux-musl` target that provides static
linking with `musl`.

However, the `olm-sys` couldn't be linked statically[^oml-sys-static-error].
The workaround have been to introduce the
`RUSTFLAGS=-Ctarget-feature=-crt-static` environment variable that disables
static linking.

The following lines have been added to copy the needed libraries.

```containerfile
COPY --from=build /usr/lib/libstdc++.so.6 /usr/lib/libstdc++.so.6
COPY --from=build /usr/lib/libgcc_s.so.1 /usr/lib/libgcc_s.so.1
COPY --from=build /lib/ld-musl-x86_64.so.1 /lib/ld-musl-x86_64.so.1
```

## Development

An image aimed at providing a development environment for developers may
be added later.
