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 `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 | ## Usage Here are some example snippets to help you get started creating a container from this image. ### docker ``` docker create \ --name=healthchecks \ -e PUID=1000 \ -e PGID=1000 \ -e SITE_ROOT= \ -e SITE_NAME= \ -e DEFAULT_FROM_EMAIL= \ -e EMAIL_HOST= \ -e EMAIL_PORT= \ -e EMAIL_HOST_USER= \ -e EMAIL_HOST_PASSWORD= \ -e EMAIL_USE_TLS= \ -e ALLOWED_HOSTS= \ -e SUPERUSER_EMAIL= \ -e SUPERUSER_PASSWORD= \ -p 8000:8000 \ -v :/config \ --restart unless-stopped \ linuxserver/healthchecks ``` ### docker-compose Compatible with docker-compose v2 schemas. ```yaml --- version: "2.1" services: healthchecks: image: linuxserver/healthchecks container_name: healthchecks environment: - PUID=1000 - PGID=1000 - SITE_ROOT= - SITE_NAME= - DEFAULT_FROM_EMAIL= - EMAIL_HOST= - EMAIL_PORT= - EMAIL_HOST_USER= - EMAIL_HOST_PASSWORD= - EMAIL_USE_TLS= - ALLOWED_HOSTS= - SUPERUSER_EMAIL= - SUPERUSER_PASSWORD= volumes: - :/config ports: - 8000:8000 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 `:` 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=` | The site's top-level URL (e.g., https://healthchecks.example.com) | | `SITE_NAME=` | The site's name (e.g., "Example Corp HealthChecks") | | `DEFAULT_FROM_EMAIL=` | From email for alerts | | `EMAIL_HOST=` | SMTP host | | `EMAIL_PORT=` | SMTP port | | `EMAIL_HOST_USER=` | SMTP user | | `EMAIL_HOST_PASSWORD=` | SMTP password | | `EMAIL_USE_TLS=` | Use TLS for SMTP (`True` or `False`) | | `ALLOWED_HOSTS=` | array of valid hostnames for the server `["test.com","test2.com"]` or `"*"` | | `SUPERUSER_EMAIL=` | Superuser email | | `SUPERUSER_PASSWORD=` | Superuser password | ### Volume Mappings (`-v`) | Volume | Function | | :----: | --- | | `/config` | database and healthchecks config directory volume mapping | ## 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: ``` $ id username uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup) ``` ## Application Setup Access the WebUI at :8000.
