Amster Usage Examples

In this section, you can find examples of tasks you can do with Amster.

Tip

For Amster examples in Docker and Kubernetes deployments, see the ForgeRock DevOps Guide.

Cloning an Access Management Instance

This example shows the high-level steps required to clone an AM instance, from exporting the configuration of the original instance, to installing the new instance and importing the configuration into it.

To Clone an AM Instance

Perform the following steps to clone an AM instance using Amster:

Create a transport key in the original AM instance, if one does not exist already. For more information, see Create Transport Keys to Export Configuration Data.
Keep the transport key safe by exporting it to another keystore. The key is required to import the configuration into the new AM instance. For more information, see "To Duplicate and Install a Transport Key".
Connect to the original AM instance using the amster command. For more information, see Connect to AM.
Export all the configuration of the original AM instance using the export-config command. For more information, see Export Configuration Data.
Take note of the value of the Password Encryption Key field on the original AM, for example, O6QWwHPO4os+zEz3Nqn/2daAYWyiFE32.
To locate it, log in to the original AM instance and navigate to Deployment > Servers > Server Name >Security > Encryption.
In the new server, deploy the AM .war file in a web container, but do not configure it.
Install the new AM instance using the install-openam command, specifying the original AM password encryption key with the --pwdEncKey option. For example:
```
am> install-openam \
> --serverUrl https://openam.example.com:8443/openam \
> --adminPwd forgerock \
> --pwdEncKey O6QWwHPO4os+zEz3Nqn/2daAYWyiFE32 \
> --acceptLicense
```
For more information, see Install AM with Amster.
Import the transport key of the original AM instance into the keystore of the new AM instance. For more information, see "To Duplicate and Install a Transport Key".
Connect to the new AM instance using the amster command. For more information, see Connect to AM.
Import the configuration of the original AM instance using the import-config command. For more information, see Import Configuration Data.

Amster Sample Scripts

This section covers sample scripts and files found in the /path/to/amster/samples directory:

transport-key.sh

Shell script to help managing transport keys. You can use it as a template for your own scripts to create, delete, and export the key to another keystore.

Invoke the script's help for a list of possible actions:

$ ./transport-key.sh help

For more information about the transport key, see Create Transport Keys to Export Configuration Data.

realm.amster
