elastic version

[mrwunderbar666]

Amcat4 documentation suggests using elastic8, but the docker compose files here still use elastic7.

This also makes the "volumes" parameter confusing, because the directory mapping differs between the versions (see: https://stackoverflow.com/questions/65668188/elastic-search-accessdeniedexception-usr-share-elasticsearch-data-nodes-0-a)

elastic8:

  - /path/to/elastic-data:/usr/share/elasticsearch/data # [local path]:[container path]

elastic7:

  - /path/to/elastic-data:/var/lib/elasticsearch/data # [local path]:[container path]

Hi, thanks for bringing this up. We talked about updating to elasticsearch 8 some time ago and weren't sure if everything is compatible and whether there were any licensing issues introduced with the new version. elasticsearch 7 is also still maintained, so we opted to support both and recommend elasticsearch 7. But since version 8 has proven to be a good and stable replacement (and the license is apparently the same for later versions of elasticsearch 7), sticking to the old version makes less sense now. So I just changed the default.

The path issue you describe makes less sense to me. We've always used /usr/share/elasticsearch/data as far as I can tell.

I assume this is resolved.
