### Build
To build the conduwuit image with docker-compose, you first need to open and
modify the `docker-compose.yml` file. There you need to comment the `image:`
option and uncomment the `build:` option. Then call docker compose with:
Official conduwuit images are built using Nix's
[`buildLayeredImage`][nix-buildlayeredimage]. This ensures all OCI images are
repeatable and reproducible by anyone, keeps the images lightweight, and can be
built offline.
```bash
docker compose up
```
This also ensures portability of our images because `buildLayeredImage` builds
OCI images, not Docker images, and works with other container software.
This will also start the container right afterwards, so if want it to run in
detached mode, you also should use the `-d` flag.
The OCI images are OS-less with only a very minimal environment of the `tini`
init system, CA certificates, and the conduwuit binary. This does mean there is
not a shell, but in theory you can get a shell by adding the necessary layers
to the layered image. However it's very unlikely you will need a shell for any
real troubleshooting.
The flake file for the OCI image definition is at [`nix/pkgs/oci-image/default.nix`][oci-image-def].
To build an OCI image using Nix, the following outputs can be built:
- `nix build -L .#oci-image` (default features, x86_64 glibc)
- `nix build -L .#oci-image-x86_64-linux-musl` (default features, x86_64 musl)
- `nix build -L .#oci-image-aarch64-linux-musl` (default features, aarch64 musl)
- `nix build -L .#oci-image-x86_64-linux-musl-all-features` (all features, x86_64 musl)
- `nix build -L .#oci-image-aarch64-linux-musl-all-features` (all features, aarch64 musl)
