diskover

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	✅	arm32v7-<version tag>

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.

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

  • 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
