This section contains information about registering clients running Amazon Linux operating systems.

Amazon Linux repository URLs are available from SUSE Customer Center

For supported products, see the support table and the release notes

When created at AWS, Amazon Linux 2 instances always have the same machine-id id at /etc/machine-id. If you are creating Amazon Linux 2 instances, make sure you regenerate the machine-id after the instances are created. For more information, see Troubleshooting Registering Cloned Clients.

1. Add Software Channels

Before you register Amazon Linux clients to your SUSE Manager Server, you need to add the required software channels, and synchronize them.

The architectures currently supported are: x86_64 and aarch64. For full list of supported products and architectures, see Supported Clients and Features.

In the following section, descriptions often default to the x86_64 architecture. Replace it with other architectures if appropriate.

For example, when working with x86_64 architecture, you need this product:

Table 1. Amazon Linux Products - WebUI
OS Version	Product Name
Amazon Linux 2	Amazon Linux 2 x86_64

Procedure: Adding Software Channels

In the SUSE Manager Web UI, navigate to Admin Setup Wizard Products.
Locate the appropriate products for your client operating system and architecture using the search bar, and check the appropriate product. This will automatically check all mandatory channels. Also all recommended channels are checked as long as the include recommended toggle is turned on. Click the arrow to see the complete list of related products, and ensure that any extra products you require are checked.
Click Add Products and wait until the products have finished synchronizing.

Alternatively, you can add channels at the command prompt. The channels you need for this procedure are:

Table 2. Amazon Linux Channels - CLI
OS Version	Base Channel
Amazon Linux 2	amazonlinux2-core-x86_64

Procedure: Adding Software Channels at the Command Prompt

At the command prompt on the SUSE Manager Server, as root, use the mgr-sync command to add the appropriate channels:

mgr-sync add channel <channel_label_1>
mgr-sync add channel <channel_label_2>
mgr-sync add channel <channel_label_n>

Synchronization starts automatically. If you want to synchronize the channels manually, use:
```
mgr-sync sync --with-children <channel_name>
```
Ensure the synchronization is complete before continuing.

2. Check Synchronization Status

Procedure: Checking Synchronization Progress from the Web UI

In the SUSE Manager Web UI, navigate to Admin Setup Wizard and select the Products tab. This dialog displays a completion bar for each product when they are being synchronized.
Alternatively, you can navigate to Software Manage Channels, then click the channel associated to the repository. Navigate to the Repositories tab, then click Sync and check Sync Status.

Procedure: Checking Synchronization Progress from the Command Prompt

At the command prompt on the SUSE Manager Server, as root, use the tail command to check the synchronization log file:
```
tail -f /var/log/rhn/reposync/<channel-label>.log
```
Each child channel generates its own log during the synchronization progress. You need to check all the base and child channel log files to be sure that the synchronization is complete.

3. Create an Activation Key

You need to create an activation key that is associated with your Amazon Linux channels.

For more information on activation keys, see Activation Keys.

4. Manage GPG Keys

Clients use GPG keys to check the authenticity of software packages before they are installed. Only trusted software can be installed on clients.

Trusting a GPG key is important for security on clients. It is the task of the administrator to decide which keys are needed and can be trusted. Because a software channel cannot be used when the GPG key is not trusted, the decision of assigning a channel to a client depends on the decision of trusting the key.

For more information about GPG keys, see GPG Keys.

5. Register Clients

To register your clients, you need a bootstrap repository. By default, bootstrap repositories are automatically created, and regenerated daily for all synchronized products. You can manually create the bootstrap repository from the command prompt, using this command:

mgr-create-bootstrap-repo
