# Development Containers

## Authentication
Before updating development images, authenticate to the registry:

```sh
docker login registry.tomastm.com
```

## Updating Development Images
Follow these steps to update development images:

### Step 1: Update and Commit Changes
- Modify the Dockerfile or install script as needed.
- Ensure that each commit updates only a single development image.
- Commit the changes to version control.

### Step 2: Build the Image
- Run the following command to build the image:

  ```sh
  ./build-image.sh <image>
  ```

- Since `dockerx` does not function properly inside `qemu`, execute this command separately on machines with different CPU architectures.
- Build the image on both `amd64` and `arm64` architectures.
- Once both architectures are built, the script will automatically generate a manifest.
