/usr/share/elasticsearch/data isn't in-line with the FHS (filesystem hierarchy standard)?

Elastic Stack Elasticsearch

As per Filesystem Hierarchy Standard

The /usr/share hierarchy is for all read-only architecture independent data files.

The example from elasticsearch at Install Elasticsearch with Docker | Elasticsearch Guide [8.11] | Elastic does not adhere to the guidance in the FHS?

For example, in other cases:

  • the default for elasticsearch (running on a host, not a container) was /var/lib/elasticsearch?
  • the default for the official mqsql container is /var/lib/mysql?

So I'd argue a good and compliant example might be -v /var/lib/elasticsearch/container/data:/var/lib/elasticsearch instead of /usr/share/elasticsearch/data

While this is a smallish issue, note examples like:

Specifically, when using Red Hat Enterprise Linux Atomic Host, the operating system content is mounted in read-only mode. There are only two writable directories for local system configuration: /etc/ and /var/.

The other interesting piece is docker-lvm-plugin, but probably only applicable to RHEL / CentOS / Fedora.

You could open an enhancement request in the ES docker repo, as it is really an issue there (how ES is started).

Thanks, will do now
