## 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`.
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:

## Updating Info
@ -179,38 +199,83 @@ Below are the instructions for updating containers:
### Via Docker Compose
* Update all images: `docker-compose pull`
* or update a single image: `docker-compose pull syslog-ng`
* Let compose update all containers as necessary: `docker-compose up -d`
* or update a single container: `docker-compose up -d syslog-ng`
* You can also remove the old dangling images: `docker image prune`
* Update images:
* All images:
```bash
docker-compose pull
```
* Single image:
```bash
docker-compose pull syslog-ng
```
* Update containers:
* All containers:
```bash
docker-compose up -d
```
* Single container:
```bash
docker-compose up -d syslog-ng
```
* You can also remove the old dangling images:
```bash
docker image prune
```
### Via Docker Run
* Update the image: `docker pull lscr.io/linuxserver/syslog-ng:latest`
* Stop the running container: `docker stop syslog-ng`
* Delete the container: `docker rm syslog-ng`
* Update the image:
```bash
docker pull lscr.io/linuxserver/syslog-ng:latest
```
* Stop the running container:
```bash
docker stop syslog-ng
```
* Delete the container:
```bash
docker rm syslog-ng
```
* 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)
* You can also remove the old dangling images: `docker image prune`
* You can also remove the old dangling images:
```bash
docker image prune
```
### Via Watchtower auto-updater (only use if you don't remember the original parameters)
* Pull the latest image at its tag and replace it with the same env variables in one run:
```bash
docker run --rm \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower \
--run-once syslog-ng
```
```bash
docker run --rm \
-v /var/run/docker.sock:/var/run/docker.sock \
containrrr/watchtower \
--run-once syslog-ng
```
* You can also remove the old dangling images: `docker image prune`
**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).

* We recommend [Diun](https://crazymax.dev/diun/) for update notifications. Other tools that automatically update containers unattended are not recommended or supported.
