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)
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
ALLOWED_HOSTS=<ALLOWED_HOSTS>
array of valid hostnames for the server ["test.com","test2.com"] (default: ["*"])
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

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.
As an example:
1
-e FILE__PASSWORD=/run/secrets/mysecretpassword
Copied!
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 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:
1
$ id username
2
uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Docker Mods

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.

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" }}' lscr.io/linuxserver/healthchecks:latest
