 **Add container** (`#add-container-view`, `libs/addContainer.js`) is a blank create form separate from **Deploy** templates: name, image, **Always pull the image**, ports (manual + publish-all-exposed), auto-remove, and advanced sections (command, volumes, network, env, labels, restart, runtime/resources). Submit uses `deployContainer` via the job tray.
 
+**Duplicate / Edit** (`#duplicateModal`, `libs/templateDeploy.js`) reuses the same deploy path with a full config editor (name, image, **Always pull the image**, ports, volumes, env, resources, security, health, etc.). When always-pull is off, the server uses a local image if present.
+
 Deploy templates form remains under the Deploy tab for catalog-driven deploys.
