# inn2 Docker container

This repository holds files neccessary to build inn2 (InterNet News 2), a NNTP server.

This container is based on [greenbender's image](https://github.com/greenbender/inn-docker).

## Usage

Configuration files are described on [inn official site](https://www.eyrie.org/~eagle/software/inn/) (select proper version from right sidebar).

Using this container with compose:

```yaml
---
services:
  inn:
    image: "code.pztrn.name/containers/inn2"
    restart: always
    ports:
      - 119:119
      - 563:563
    volumes:
      - "./data/db:/inn2/db"
      - "./data/etc:/inn2/etc"
      - "./data/log:/inn2/log"
      - "./data/run:/inn2/run"
      - "./data/spool:/inn2/spool"
      - "./data/tmp:/inn2/tmp"
    ulimits:
      nofile:
        soft: 65535
        hard: 65535
```

## Cronjobs

There is a section in documentation about cron jobs you should configure. This docker image currently isn't supporting these, so configure it separately with lines like:

```shell
0 3 * * * docker compose run inn news.daily expireover lowmark
```

## Versioning

Image versioning follows official inn2 versions with additional optional version postfix added to indicate image fixes for particular version.

Examples:

* 2.7.4-3 - inn version 2.7.4 and 3 additional fixes applied to container.
* 2.7.6 - inn version 2.7.6 without additional container fixes.

## Data directories and permissions

Configuration is kept in `/inn2/etc`, mount it in your local filesystem. Entrypoint script will copy default configuration for you if missing.

This container exposes `/inn2/db`, `/inn2/spool`, `/inn2/log` as volumes, so you may either:

* Leave as is, Docker will create separate volume for your data.
* Mount volume somewhere, like in compose example above.

inn2 is launched as UID/GID 600 in container, so chown directories properly according to your Docker configuration:

* If you're not using userns isolation - use `chown 600:600`.
* If you're using it - use `600 + id from /etc/subuid`, e.g. if you're using default Docker remapping this could be `chown 100600:100600`.
