Category: Elastic Search

Running Elasticsearch inside Docker on a Plesk server gives you fast, relevant search without exposing your cluster to the public internet. This step-by-step guide walks through host prep, deploying the official images, and proxying safely through a domain so TLS terminates at Plesk while Elasticsearch and Kibana speak HTTP internally. We cover the gotchas you’ll actually hit—vm.max_map_count, path-prefix proxying, why Kibana needs a service account token (not the elastic user), and sizing memory limits so MySQL and PHP-FPM stay happy. The result is a tidy, single-node setup that supercharges WordPress search (e.g., via ElasticPress), keeps management simple, and leaves you room to grow.
