Production Cluster: Migrating from Search Guard 53 and before
This chapter describes how to migrate a cluster running legacy Search Guard configuration to the new structure with minimal outage.
- You should do a test run on a test cluster before doing the actual migration.
- Users that were logged into Kibana while the update is performed, will need to log in again after the update is finalized.
In order to perform the migration, you need the following:
- The file
sg_config.ymlfrom the existing Elasticsearch setup.
sg_config.ymlreferences further files, such as PEM files. You need these as well.
- If you are also using Kibana, you need the file
configdirectory of the existing Kibana setup.
- You need to download the
sgctltool. It does not require any special installation, just copy it to a suitable place and execute it.
Migrating the Configuration
Open a shell and perform the following steps:
- Create a work directly
sgctl migrate-config /path/to/legacy/sg_config.yml /path/to/legacy/kibana.yml -o /path/to/your/work/directory. Be sure to specify the correct paths to the files
kibana.yml. If you are using Elasticsearch 7.11 or newer, additionally specify the option
--target-platform es711. If you are not using Kibana, just omit the path to
sgctlwill now create new configuration files and print additional information to the console. Carefully review the printed information and the produced configuration.
- The new Search Guard version requires that users who shall be allowed to log into Kibana have a certain privilege. If your users are mapped to the role
SGS_KIBANA_USER(which was already a recommended practice before), the users will automatically have that privilege. If your users are not mapped to the role, you need to edit your role mapping accordingly.
Applying the Configuration
To execute the update, follow this process:
- Perform a rolling update of the Search Guard Elasticsearch plugin.
sgctlto upload the
sg_frontend_authc.ymlfile produced by
- Perform an update of the Search Guard Kibana plugin. Also, copy the new
kibana.ymlfile to the
configdirectory of the Kibana installation.
- Restart the Kibana instance.
- Now also upload the other generated files (
sg_authc.yml, and possibly
sg_license_key.yml) file using
The update is now finished. Users which were logged in before, will now have to login again once.
