Build a Container Image
=======================
This container image includes ejabberd as a standalone OTP release built using Elixir.

## Package build for `arm64`
By default, `.github/container/Dockerfile` builds this container by directly compiling ejabberd,
it is a fast and direct method.
However, a problem with QEMU prevents building the container in QEMU using Erlang/OTP 25
for the `arm64` architecture.
Providing `--build-arg METHOD=package` is an alternate method to build the container
used by the Github Actions workflow that provides `amd64` and `arm64` container images.
It first builds an ejabberd binary package, and later installs it in the image.
That method avoids using QEMU, so it can build `arm64` container images, but is extremely
slow the first time it's used, and consequently not recommended for general use.
In this case, to build the ejabberd container image for arm64 architecture:
```bash
docker buildx build \
--build-arg METHOD=package \
--platform linux/arm64 \
-t personal/ejabberd:$VERSION \
-f .github/container/Dockerfile \
.
```
