Config

List any changed config values here!!!

/etc/elasticsearch/elasticsearch.yml:

network.host: localhost
discovery.type: single-node
xpack.security.enabled: true

/home/mastodon/.env.production

idk if we should put this part online but there is some config here too

Memory

the ES docs say to allocate half your available memory to the heap. At the moment (23-10-26) we are using 2.5G/8G memory at rest. Going to try allocating 3GB and see what happens

/lib/systemd/system/elasticsearch.service

[Service]
Environment=ES_HEAP_SIZE=3g

• (pretty old at this point and also ES says not do to the JVM memory size thing) https://github.com/felx/mastodon-documentation/blob/master/Running-Mastodon/Elasticsearch-guide.md

Since we are running on a small VPS, we might need to configure it for a low memory environment!
