linuxserver/diskover ¶

diskover is an open source file system indexer that uses Elasticsearch to index and manage data across heterogeneous storage systems.

Supported Architectures¶

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/diskover: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	✅	amd64-<version tag>
arm64	✅	arm64v8-<version tag>
armhf	❌

Application Setup¶

This application is dependent on an ElasticSearch instance. Please see the example compose file for additional information.

The default username is diskover with the password of darkdata, access the container at http://<host-ip>/. The UI may be unusable until a valid index has been created.

The default diskover-web Constants.php file located at /config/diskover-web.conf.d/Constants.php will need to be edited to allow diskover-web to communicate with the ElasticSearch container. The following entries will need to be edited: * const ES_HOST = 'elasticsearch'; * const ES_PORT = 9200;

The application doesn't start an index by default. A crontab is created inside of the /config directory and can be set up to run automated indexes of /data. Changes to this crontab file require a restart to apply. You can also manually run an index by executing /app/diskover/diskover.py either in interactive or detached mode:

docker exec -u abc -d diskover python3 /app/diskover/diskover.py -i diskover-my_index_name /data Will run an index in the background
docker exec -u abc -it diskover python3 /app/diskover/diskover.py -i diskover-my_index_name /data Will run an index in the foreground

Usage¶

To help you get started creating a container from this image you can either use docker-compose or the docker cli.

docker cli (click here for more info)¶

docker run -d \
  --name=diskover \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Etc/UTC \
  -e ES_HOST=elasticsearch \
  -e ES_PORT=9200 \
  -e ES_USER=elastic \
  -e ES_PASS=changeme \
  -p 80:80 \
  -v /path/to/diskover/config:/config \
  -v /path/to/diskover/data:/data \
  --restart unless-stopped \
  lscr.io/linuxserver/diskover:latest

Parameters¶

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.

Ports (`-p`)¶

Parameter	Function
`80`	diskover Web UI

Environment Variables (`-e`)¶

Env	Function
`PUID=1000`	for UserID - see below for explanation
`PGID=1000`	for GroupID - see below for explanation
`TZ=Etc/UTC`	specify a timezone to use, see this list.
`ES_HOST=elasticsearch`	ElasticSearch host (optional)
`ES_PORT=9200`	ElasticSearch port (optional)
`ES_USER=elastic`	ElasticSearch username (optional)
`ES_PASS=changeme`	ElasticSearch password (optional)

Volume Mappings (`-v`)¶

Volume	Function
`/config`	Persistent config files
`/data`	Default mount point to crawl

Miscellaneous Options¶

Parameter	Function

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__MYVAR=/run/secrets/mysecretvariable

Will set the environment variable MYVAR based on the contents of the /run/secrets/mysecretvariable 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 your_user as below:

id your_user

Example output:

uid=1000(your_user) gid=1000(your_user) groups=1000(your_user)

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 diskover /bin/bash
```
To monitor the logs of the container in realtime:
```
docker logs -f diskover
```

Container version number:

docker inspect -f '{{ index .Config.Labels "build_version" }}' diskover

Image version number:

docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/diskover:latest

Updating Info¶

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:

Via Docker Compose¶

Update images:

All images:
```
docker-compose pull
```
Single image:
```
docker-compose pull diskover
```

Update containers:

All containers:
```
docker-compose up -d
```
Single container:
```
docker-compose up -d diskover
```

You can also remove the old dangling images:
```
docker image prune
```

Via Docker Run¶

Update the image:

docker pull lscr.io/linuxserver/diskover:latest

Stop the running container:
```
docker stop diskover
```
Delete the container:
```
docker rm diskover
```
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
```

Image Update Notifications - Diun (Docker Image Update Notifier)¶

Tip

We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.

Building locally¶

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-diskover.git
cd docker-diskover
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/diskover:latest .

The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static

docker run --rm --privileged multiarch/qemu-user-static:register --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.
