This internal tool is used as a desktop sandbox in our CI process to grab a screenshot of a hopefully functional endpoint

## 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/tester` 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 | latest |


## Usage

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

### docker

```
docker create \
  --name=tester \
  -e URL=http://google.com \
  -p 3000:3000 \
  --restart unless-stopped \
  linuxserver/tester
```


### docker-compose

Compatible with docker-compose v2 schemas.

```yaml
---
version: "2.1"
services:
  tester:
    image: linuxserver/tester
    container_name: tester
    environment:
      - URL=http://google.com
    ports:
      - 3000:3000
    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 |
| :----: | --- |
| `3000` | WebUI |


### Environment Variables (`-e`)

| Env | Function |
| :----: | --- |
| `URL=http://google.com` | Specify an endpoint, the container will automatically determine the correct protocol and program to use |

### Volume Mappings (`-v`)

| Volume | Function |
| :----: | --- |



## Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend `FILE__`.

As an example:

```
-e FILE__PASSWORD=/run/secrets/mysecretpassword
```

Will set the environment variable `PASSWORD` based on the contents of the `/run/secrets/mysecretpassword` file.

## Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional `-e UMASK=022` setting.
Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up [here](https://en.wikipedia.org/wiki/Umask) before asking for support.



## Docker Mods
[![Docker Mods](https://img.shields.io/badge/dynamic/yaml?color=94398d&labelColor=555555&logoColor=ffffff&style=for-the-badge&label=mods&query=%24.mods%5B%27tester%27%5D.mod_count&url=https%3A%2F%2Fraw.githubusercontent.com%2Flinuxserver%2Fdocker-mods%2Fmaster%2Fmod-list.yml)](https://mods.linuxserver.io/?mod=tester "view available mods for this container.")

We publish various [Docker Mods](https://github.com/linuxserver/docker-mods) to enable additional functionality within the containers. The list of Mods available for this image (if any) can be accessed via the dynamic badge above.


## Support Info

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

## Versions

* **18.04.20:** - Initial release.
