​diskover is a file system crawler and disk space usage software that uses Elasticsearch to index and manage data across heterogeneous storage systems.

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 linuxserver/diskover 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:

Usage

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

  -e ES_HOST=elasticsearch \
  -e ES_PORT=9200 \
  -e ES_USER=elastic \
  -e ES_PASS=changeme \
  -e INDEX_NAME=diskover- \
  -e DISKOVER_OPTS= \
  -e WORKER_OPTS= \
  -e RUN_ON_START=true \
  -e USE_CRON=true \
  -p 80:80 \
  -p 9181:9181 \
  -p 9999:9999 \
  -v </path/to/diskover/config>:/config \
  -v </path/to/diskover/data>:/data \
  --restart unless-stopped \

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)

Environment Variables (-e)

Volume Mappings (-v)

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)

Application Setup

Once running the URL will be http://<host-ip>/ initial application spinup will take some time so please reload if you get an empty response. We highly reccomend using Docker compose for this image as it includes multiple database backends to link into. If you are looking to mount the elasticsearch and redis data to your host machine for access neither of them currently support setting a custom UID or GID they will run by default as:

• Redis - UID=999 GID=999

• Elasticsearch - UID=1000 GID=1000

ElasticSearch also requires a sysctl setting on the host machine to run properly. Running sysctl -w vm.max_map_count=262144 will solve this issue. To make this setting persistent through reboots, set this value in /etc/sysctl.conf.

If you simply want the application to work you can mount these to folders with 0777 permissions, otherwise you will need to create these users host level and set the folder ownership properly.

By default this compose example is pointed to a single directory and the UID and GID you pass to the diskover container needs to match that folders ownership. If these are shared folders with many owners the indexing will likely fail.

For specific questions or help setting up diskover in your environment please refer to the project's Github page Diskover.
