[Znc](http://wiki.znc.in/ZNC) is an IRC network bouncer or BNC. It can detach the client from the actual IRC server, and also from selected channels. Multiple clients from different locations can connect to a single ZNC account simultaneously and therefore appear under the same nickname on IRC.

## Supported Architectures

Our images support multiple architectures such as `x86-64`, `arm64` and `armhf`. We utilise the docker manifest for multi-platform awareness. More information is available from docker [here](https://github.com/docker/distribution/blob/master/docs/spec/manifest-v2-2.md#manifest-list) and our announcement [here](https://blog.linuxserver.io/2019/02/21/the-lsio-pipeline-project/).

Simply pulling `linuxserver/znc` should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

| Architecture | Tag |
| :---: | :--- |
| x86-64 | amd64-latest |
| arm64 | arm64v8-latest |
| armhf | arm32v6-latest |

## Usage

Here are some example snippets to help you get started creating a container from this image.

### docker

```text
docker create \
  --name=znc \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -p 6501:6501 \
  -v <path to data>:/config \
  --restart unless-stopped \
  linuxserver/znc
```

### docker-compose

Compatible with docker-compose v2 schemas.

```yaml
---
version: "2"
services:
  znc:
    image: linuxserver/znc
    container_name: znc
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
    volumes:
      - <path to data>:/config
    ports:
      - 6501:6501
    restart: unless-stopped
```

## Parameters

Docker images are configured using parameters passed at runtime \(such as those above\). These parameters are separated by a colon and indicate `<external>:<internal>` respectively. For example, `-p 8080:80` would expose port `80` from inside the container to be accessible from the host's IP on port `8080` outside the container.

### Ports \(`-p`\)

| Parameter | Function |
| :---: | :--- |
| `6501` | Port ZNC listens on. |

### Environment Variables \(`-e`\)

| Env | Function |
| :---: | :--- |
| `PUID=1000` | for UserID - see below for explanation |
| `PGID=1000` | for GroupID - see below for explanation |
| `TZ=Europe/London` | Specify a timezone to use EG Europe/London. |

### Volume Mappings \(`-v`\)

| Volume | Function |
| :---: | :--- |
| `/config` | Where local ZNC data is stored. |

## User / Group Identifiers

When using volumes \(`-v` flags\), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user `PUID` and group `PGID`.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance `PUID=1000` and `PGID=1000`, to find yours use `id user` as below:

```text
  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)
```

## Application Setup

To log in to the application, browse to https://:6501.

* Default User: admin
* Default Password: admin

  `change password ASAP.`

## Support Info

* Shell access whilst the container is running: 
  * `docker exec -it znc /bin/bash`
* To monitor the logs of the container in realtime: 
  * `docker logs -f znc`
* Container version number 
  * `docker inspect -f '{{ index .Config.Labels "build_version" }}' znc`
* Image version number
  * `docker inspect -f '{{ index .Config.Labels "build_version" }}' linuxserver/znc`
