Description Victor Grousset/tuxayo 2020-06-06 03:19:24 UTC 
I just started koha-testing-docker with ES7 (ran ku-es7)
Comment 1 Victor Grousset/tuxayo 2020-06-06 03:23:26 UTC 
Odd, ES6 doesn't do a deprecation warning about this. I though it worked like that so there would never be a bad surprise when upgrading to a major version.
Comment 2 Kevin Carnes 2021-06-22 09:03:52 UTC 
Adding "- discovery.type=single-node" under environment in docker-compose.es7.yml fixed the problem for me.

Bug 25684: ElasticSearch 7 start crash: at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

With Elasticsearch 7 it is necessary to specify if using a single node

To test:
1) run ku-es7
2) Observe that Elasticsearch stops with an error
3) Apply patch
4) run ku-es7
5) Observe that Elasticsearch starts successfully
6) Sign off

Great so it's not a Koha problem!

It's about koha-testing-docker, the repository is there: https://gitlab.com/koha-community/koha-testing-docker

So the patch must be submitted there

Confirmed to be working :)
