linuxserver/grav

Grav is a Fast, Simple, and Flexible, file-based Web-platform.

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 ghcr.io/linuxserver/grav 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

For more information check out the Grav documentation. Our image includes the grav-admin plugin.

There is a known issue where the admin plugin scheduler reports Cron Not Available for user: abc however this is purely cosmetic and the scheduler will function normally.

Usage

Here are some example snippets to help you get started creating a container from this image.

docker-compose (recommended)

Compatible with docker-compose v2 schemas.

---
version: "2.1"
services:
  grav:
    image: ghcr.io/linuxserver/grav
    container_name: grav
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=America/New_York
    volumes:
      - /path/to/appdata/config:/config
    ports:
      - 80:80
    restart: unless-stopped

docker cli

docker run -d \
  --name=grav \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=America/New_York \
  -p 80:80 \
  -v /path/to/appdata/config:/config \
  --restart unless-stopped \
  ghcr.io/linuxserver/grav

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
80	Port for web frontend

Environment Variables (-e)

Env	Function
PUID=1000	for UserID - see below for explanation
PGID=1000	for GroupID - see below for explanation
TZ=America/New_York	Specify a timezone to use EG America/New_York

Volume Mappings (-v)

Volume	Function
/config	Contains all relevant configuration files.

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-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 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:

  $ id username
    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 grav /bin/bash
• To monitor the logs of the container in realtime:
  • docker logs -f grav
• Container version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' grav
• Image version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' ghcr.io/linuxserver/grav

Versions

• 09.04.21: - Initial Release.
