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.
We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.
Simply pulling lscr.io/linuxserver/healthchecks:latest
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 | Available | Tag |
---|---|---|
x86-64 | âś… | amd64-<version tag> |
arm64 | âś… | arm64v8-<version tag> |
armhf | ❌ |
Access the WebUI at :8000. For more information, check out Healthchecks.
See here for a complete list of available environment variables.
To help you get started creating a container from this image you can either use docker-compose or the docker cli.
Note
Unless a parameter is flaged as 'optional', it is mandatory and a value must be provided.

lscr.io/linuxserver/healthchecks:latest
Containers 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.
Parameter | Function |
---|---|
-p 8000:8000 |
Healthchecks Web UI |
-p 2525 |
Port for inbound SMTP pings |
-e PUID=1000 |
for UserID - see below for explanation |
-e PGID=1000 |
for GroupID - see below for explanation |
-e TZ=Etc/UTC |
specify a timezone to use, see this list. |
-e SITE_ROOT= |
The site's top-level URL and the port it listens to if different than 80 or 443 (e.g., https://healthchecks.example.com:8000). |
-e SITE_NAME= |
The site's name (e.g., "Example Corp HealthChecks"). |
-e SUPERUSER_EMAIL= |
Superuser email. |
-e SUPERUSER_PASSWORD= |
Superuser password. |
-e ALLOWED_HOSTS= |
A comma-separated list of valid hostnames for the server. Default is: * . |
-e APPRISE_ENABLED=False |
Set to True to enable the Apprise integration (https://github.com/caronc/apprise). |
-e CSRF_TRUSTED_ORIGINS= |
A list of trusted origins for unsafe requests (e.g. POST). Defaults to the value of SITE_ROOT . |
-e DEBUG=True |
Set to False to disable. Debug mode relaxes CSRF protections and increases logging verbosity but should be disabled for production instances as it will impact performance and security. |
-e DEFAULT_FROM_EMAIL= |
From email for alerts. |
-e EMAIL_HOST= |
SMTP host. |
-e EMAIL_PORT= |
SMTP port. |
-e EMAIL_HOST_USER= |
SMTP user. |
-e EMAIL_HOST_PASSWORD= |
SMTP password. |
-e EMAIL_USE_TLS= |
Use TLS for SMTP (True or False ). |
-e INTEGRATIONS_ALLOW_PRIVATE_IPS= |
Defaults to False. Set to True to allow integrations to connect to private IP addresses. |
-e PING_EMAIL_DOMAIN= |
The domain to use for generating ping email addresses. Defaults to localhost . |
-e RP_ID= |
If using webauthn for 2FA set this to match your Healthchecks domain. Webauthn will only work over https. |
-e SECRET_KEY= |
A secret key used for cryptographic signing. Will generate a random value if one is not supplied and save it to /config/local_settings.py . |
-e SITE_LOGO_URL= |
Full URL to custom site logo. |
-v /config |
Persistent config files. |
You can set any environment variable from a file by using a special prepend FILE__
.
As an example:
-e FILE__MYVAR=/run/secrets/mysecretvariable
Will set the environment variable MYVAR
based on the contents of the /run/secrets/mysecretvariable
file.
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 before asking for support.
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 your_user
as below:
id your_user
Example output:
uid=1000(your_user) gid=1000(your_user) groups=1000(your_user)
We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.
-
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" }}' lscr.io/linuxserver/healthchecks:latest
Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (noted in the relevant readme.md), we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.
Below are the instructions for updating containers:
-
Update images:
-
All images:
docker-compose pull
-
Single image:
docker-compose pull healthchecks
-
-
Update containers:
-
All containers:
docker-compose up -d
-
Single container:
docker-compose up -d healthchecks
-
-
You can also remove the old dangling images:
docker image prune
-
Update the image:
docker pull lscr.io/linuxserver/healthchecks:latest
-
Stop the running container:
docker stop healthchecks
-
Delete the container:
docker rm healthchecks
-
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
Tip
We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.
If you want to make local modifications to these images for development purposes or just to customize the logic:
git clone https://github.com/linuxserver/docker-healthchecks.git
cd docker-healthchecks
docker build \
--no-cache \
--pull \
-t lscr.io/linuxserver/healthchecks:latest .
The ARM variants can be built on x86_64 hardware and vice versa using lscr.io/linuxserver/qemu-static
docker run --rm --privileged lscr.io/linuxserver/qemu-static --reset
Once registered you can define the dockerfile to use with -f Dockerfile.aarch64
