## Usage
Here are some example snippets to help you get started creating a container.
To help you get started creating a container from this image you can either use docker-compose or the docker cli.
### docker-compose (recommended, [click here for more info](https://docs.linuxserver.io/general/docker-compose))

## Parameters
Container 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.

## 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.

### Via Docker Compose
* Update all images: `docker-compose pull`
* or update a single image: `docker-compose pull plex`
* Let compose update all containers as necessary: `docker-compose up -d`
* or update a single container: `docker-compose up -d plex`
* You can also remove the old dangling images: `docker image prune`
* Update images:
* All images:
```bash
docker-compose pull

* Update containers:
* All containers:
```bash
docker-compose up -d
```
* Single container:
```bash
docker-compose up -d plex

* You can also remove the old dangling images:

### Via Docker Run
* Update the image: `docker pull lscr.io/linuxserver/plex:latest`
* Stop the running container: `docker stop plex`
* Delete the container: `docker rm plex`
* Update the image:
```bash
docker pull lscr.io/linuxserver/plex:latest
```
* Stop the running container:
```bash
docker stop plex

* Delete the container:
```bash
docker rm plex

* Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your `/config` folder and settings will be preserved)

**Note:** We do not endorse the use of Watchtower as a solution to automated updates of existing Docker containers. In fact we generally discourage automated updates. However, this is a useful tool for one-time manual updates of containers where you have forgotten the original parameters. In the long term, we highly recommend using [Docker Compose](https://docs.linuxserver.io/general/docker-compose).
