[Healthchecks](https://github.com/healthchecks/healthchecks) is a watchdog for your cron jobs. It's a web server that listens for pings from your cron jobs, plus a web interface.

## 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 `lscr.io/linuxserver/healthchecks` 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 | arm32v7-latest |

## Application Setup

Access the WebUI at <your-ip>:8000. For more information, check out [Healthchecks](https://github.com/healthchecks/healthchecks).

## Usage

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

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 |
| :----: | --- |
| `8000` | will map the container's port 8000 to port 8000 on the host |

### Environment Variables (`-e`)

| Env | Function |
| :----: | --- |
| `PUID=1000` | for UserID - see below for explanation |
| `PGID=1000` | for GroupID - see below for explanation |
| `SITE_ROOT=<SITE_ROOT>` | The site's top-level URL and the port it listens to if differrent than 80 or 443 (e.g., https://healthchecks.example.com:8000) |
| `SITE_NAME=<SITE_NAME>` | The site's name (e.g., "Example Corp HealthChecks") |
| `DEFAULT_FROM_EMAIL=<DEFAULT_FROM_EMAIL>` | From email for alerts |
| `EMAIL_HOST=<EMAIL_HOST>` | SMTP host |
| `EMAIL_PORT=<EMAIL_PORT>` | SMTP port |
| `EMAIL_HOST_USER=<EMAIL_HOST_USER>` | SMTP user |
| `EMAIL_HOST_PASSWORD=<EMAIL_HOST_PASSWORD>` | SMTP password |
| `EMAIL_USE_TLS=<True or False>` | Use TLS for SMTP (`True` or `False`) |
| `ALLOWED_HOSTS=<ALLOWED_HOSTS>` | array of valid hostnames for the server `["test.com","test2.com"]` (default: `["*"]`) |
| `SUPERUSER_EMAIL=<SUPERUSER_EMAIL>` | Superuser email |
| `SUPERUSER_PASSWORD=<SUPERUSER_PASSWORD>` | Superuser password |
| `REGENERATE_SETTINGS=True/False` | Defaults to False. Set to true to always override the `local_settings.py` file with values from environment variables. Do not set to True if you have made manual modifications to this file. |
| `SITE_LOGO_URL=<SITE_LOGO_URL>` | Custom site logo URL |
| `SECRET_KEY=<SECRET_KEY>` | A secret key used for cryptographic signing. docker-healthchecks will generate a secure value if one does not exist |
| `APPRISE_ENABLED=True/False` | Defaults to False. A boolean that turns on/off the Apprise integration (https://github.com/caronc/apprise) |

### Volume Mappings (`-v`)

| Volume | Function |
| :----: | --- |
| `/config` | database and healthchecks config directory volume mapping |

#### Miscellaneous Options

| Parameter | 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:

```bash
-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.

## 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:

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