linuxserver/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 and our announcement here.

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=<SITE_ROOT> \
  -e SITE_NAME=<SITE_NAME> \
  -e DEFAULT_FROM_EMAIL=<DEFAULT_FROM_EMAIL> \
  -e EMAIL_HOST=<EMAIL_HOST> \
  -e EMAIL_PORT=<EMAIL_PORT> \

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 `e.g., [https://healthchecks.example.com](https://healthchecks.example.com)`
`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"]` or `"*"`
`SUPERUSER_EMAIL=<SUPERUSER_EMAIL>`	Superuser email
`SUPERUSER_PASSWORD=<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. For more information, check out Healthchecks.

Docker Mods

We publish various 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 healthchecks /bin/bash
To monitor the logs of the container in realtime:
- docker logs -f healthchecks
Container version number
- docker inspect -f '{{ index .Config.Labels "build_version" }}' healthchecks
Image version number
- docker inspect -f '{{ index .Config.Labels "build_version" }}' linuxserver/healthchecks
