# docker-images
> Dockerfiles and scripts to build various Docker images I rely on.
## System Requirements
- Linux
- Bash
- Docker
## Getting started
The script that does the magic is called `imagebuilder.sh` in the root of this repository. Run it to get usage information:
```bash
./imagebuilder.sh
```
## Development Notes
At present, 3 image types are present:
- **`base`:** A base image - a script is called with an auto-generated output directory as the 1st and only argument. When the script exits the directory is checked for a `.tar.gz` file
- **`base-nopush`:** A variant of the above that doesn't automatically much to the docker registry on completion.
- **`docker`:** A `Dockerfile` is is built with `docker build` before being pushed to the docker registry.
Image | Purpose
----------------|----------------
`minideb` | Our main base image for (most) other images. Built from [minideb](https://github.com/bitnami/minideb), but customised to use our [[Wopplefox/apt-cacher-ng|apt-cacher-ng]] instance.
`docker-registry-ui`| [docker registry ui](https://github.com/Joxit/docker-registry-ui), dockerised
`jellyfin` | Dockerised [jellyfin](https://jellyfin.org/)
`etherpad` | Dockerised [etherpad](https://etherpad.org/)
