Mass Configuration

Mass configuration is possible with branch servers and terminals.

Mass configuration tool was not yet adapted for containerized saltboot workflow.

1. Branch Server Mass Configuration

Branch servers are configured individually using formulas. If you are working in an environment with many branch servers, it often helps to configure branch servers automatically with a pre-defined configuration file, rather than configuring each one individually.

Before working with the mass configuration tool, back up the existing branch servers configuration.

The mass configuration tool overwrites the existing configuration with data specified in the provided YAML file.

The mass configuration tool does not support all possible formula configurations. Always make sure on a small sample that the mass configuration tool can configure systems as expected.

1.1. Configure Multiple Branch Servers

Configuring multiple branch servers requires the python-susemanager-retail package, which is provided with Uyuni for Retail. Install the python-susemanager-retail package on the Uyuni server.

Procedure: Configuring Multiple Branch Servers

  1. Create a YAML file describing the infrastructure you intend to install. For an example YAML file, see Example YAML File for Mass Configuration.

  2. On a clean Uyuni for Retail installation, import the YAML file you have created:

    retail_yaml --from-yaml filename.yaml

    See the retail_yaml --help output for additional options.

  3. In the Uyuni Web UI, check that your systems are listed correctly. Also check that the formulas you require are available.

  4. Create activation keys for each of your branch servers, register them using bootstrap, and configure them as proxy servers.

  5. In the States tab, click Apply Highstate to deploy your configuration changes for each branch server.

If you need to change your configuration, you can edit the YAML file at any time, and use the retail_yaml --from-yaml command to upload the new configuration.

Use empty profiles together with activation keys to onboard all the systems of your infrastructure. Use an activation key to assign the channels listed in Set Up the Uyuni for Retail Environment.

2. Terminal Mass Configuration

If you are working in an environment with many terminals, it often helps to configure terminals automatically with a pre-defined configuration file, rather than configuring each one individually.

You will need to have your infrastructure planned out ahead of time, including the IP addresses, hostnames, and domain names of branch servers and terminals. You will also require the hardware (MAC) addresses of each terminal.

The settings specified in the configuration file cannot always be successfully applied. In cases where there is a conflict, Uyuni will ignore the request in the file. This is especially important when designating hostnames. You should always check that the details have been applied as expected after using this configuration method.

2.1. Configure Multiple Terminals

Procedure: Configuring Multiple Terminals

  1. Create a YAML file describing the infrastructure you intend to install, specifying the hardware address for each terminal. For an example YAML file, see Example YAML File for Mass Configuration.

  2. On a clean Uyuni installation, import the YAML file you have created:

    retail_yaml --from-yaml filename.yaml

    See the retail_yaml --help output for additional options.

  3. In the Uyuni Web UI, check that your systems are listed and displaying correctly, and the formulas you require are available.

  4. Create activation keys for each of your branch servers, connect them using bootstrap, and configure them as proxy servers.

  5. In the States tab, click Apply Highstate to deploy your configuration changes for each branch server.

  6. Connect your terminals according to your infrastructure plan.

If you need to change your configuration, you can edit the YAML file at any time, and use the retail_yaml --from-yaml command to upload the new configuration.

3. Export Configuration to Mass Configuration File

If you already have a configuration that you would like to export to a YAML file, use:

retail_yaml --to-yaml filename.yaml

This can be a good way to create a basic mass configuration file. However, it is important to check the file before using it, because some mandatory configuration entries may be missing.

When you are designing your configuration and creating the YAML file, ensure the branch server ID matches the fully qualified hostname, and the Salt ID. If these do not match, the bootstrap script could fail.
