Not sure if topic support / docker is correct or it should be installation or fulltextsearch. This is a question as suggested by daita on the github issue [Elasticsearch\Common\Exceptions\NoNodesAvailableException] 路 Issue #256 路 nextcloud/fulltextsearch 路 GitHub
I have nextcloud, postgres, elastic search and only office document server running each in their docker container, sharing one docker network. Nextcloud, postgres and only office can communicate, the last piece in the puzzle missing is elastic search.
When I try to create the initial index using
docker exec nextcloud su -l www-data -s /bin/sh -c "php -d memory_limit=10G -f /var/www/html/occ fulltextsearch:index -v"
Then I see the following output:
indexing.
[Elasticsearch\Common\Exceptions\NoNodesAvailableException]

fulltextsearch:index [--output [OUTPUT]]
However, when I try to access elastic search from that container using curl it works:
docker exec nextcloud su -l www-data -s /bin/sh -c "curl http://nextcloud_elastic_search:9200/_cat/indices"
gives me the following response:

I created the nextcloud index manually, I didn鈥檛 install readonlyrest, because my elastic search instance doesn鈥檛 expose the port outside of the docker container on a machine which itself isn鈥檛 directly publicly accessible.
Below you can see a screenshot of the full text search admin configuration.
I鈥檓 really puzzled as to what could be wrong, since I couldn鈥檛 find any additional logs what so ever.
I even tried enabling readonlyrest but also that didn鈥檛 seem to help
I鈥檓 using the following docker images:
nextcloud:12.0.5docker.elastic.co/elasticsearch/elasticsearch:6.1.2
any ideas?
