Lost a Docker host but still have the EBS snapshot? This step-by-step playbook shows how to recover a Dockerized app without a running daemon: locate the right container, map mount IDs, pull files from overlay2//diff, extract env/config (safely), and spin up a minimal replacement. Includes volume handling and security gotchas.
Choosing the right storage for Docker can make or break your app’s reliability. This guide explains volumes, bind mounts, and tmpfs, how storage drivers like overlay2 affect performance, and exactly how to inspect a running container to see where its data lives—plus backups, security, and Compose tips.
Container log bloat is a hidden culprit behind full disks on Docker hosts. Learn how to spot oversized logs, clean them up, and configure rotation so they never grow out of control again.
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.
