Chapter 7. Managing Application Life Cycles This chapter outlines the application life cycle in Satellite and how to create and remove application life cycles for Satellite and Capsule. 7.1. Introduction to Application Life Cycle The application life cycle is a concept central to Satellite's content management functions. The application life cycle defines how a particular system and its software look at a particular stage. For example, an application life cycle might be simple; you might only have a development stage and production stage. In this case the application life cycle might look like this: Development Production However, a more complex application life cycle might have further stages, such as a phase for testing or a beta release. This adds extra stages to the application life cycle: Development Testing Beta Release Production Satellite provides methods to customize each application life cycle stage so that it suits your specifications. Each stage in the application life cycle is called an environment in Satellite. Each environment uses a specific collection of content. Satellite defines these content collections as a Content View. Each Content View acts as a filter where you can define what repositories, and packages to include in a particular environment. This provides a method for you to define specific sets of content to designate to each environment. For example, an email server might only require a simple application life cycle where you have a production-level server for real-world use and a test server for trying out the latest mail server packages. When the test server passes the initial phase, you can set the production-level server to use the new packages. Another example is a development life cycle for a software product. To develop a new piece of software in a development environment, test it in a quality assurance environment, pre-release as a beta, then release the software as a production-level application. Figure 7.1. The Satellite Application Life Cycle 7.2. Promoting Content across the Application Life Cycle In the application life cycle chain, when content moves from one environment to the , this is called promotion . Example Content Promotion Across Satellite Life Cycle Environments Each environment contains a set of systems registered to Red Hat Satellite. These systems only have access to repositories relevant to their environment. When you promote packages from one environment to the , the target environment's repositories receive new package versions. As a result, each system in the target environment can update to the new package versions. Development Testing Production example_software -1.1-0.noarch.rpm example_software -1.0-0.noarch.rpm example_software -1.0-0.noarch.rpm After completing development on the patch, you promote the package to the Testing environment so the Quality Engineering team can review the patch. The application life cycle then contains the following package versions in each environment: Development Testing Production example_software -1.1-0.noarch.rpm example_software -1.1-0.noarch.rpm example_software -1.0-0.noarch.rpm While the Quality Engineering team reviews the patch, the Development team starts work on example_software 2.0. This results in the following application life cycle: Development Testing Production exampleware-2.0-0.noarch.rpm exampleware-1.1-0.noarch.rpm exampleware-1.0-0.noarch.rpm The Quality Engineering team completes their review of the patch. Now example_software 1.1 is ready to release. You promote 1.1 to the Production environment: Development Testing Production example_software -2.0-0.noarch.rpm example_software -1.1-0.noarch.rpm example_software -1.1-0.noarch.rpm The Development team completes their work on example_software 2.0 and promotes it to the Testing environment: Development Testing Production example_software -2.0-0.noarch.rpm example_software -2.0-0.noarch.rpm example_software -1.1-0.noarch.rpm Finally, the Quality Engineering team reviews the package. After a successful review, promote the package to the Production environment: Development Testing Production exampleware-2.0-0.noarch.rpm exampleware-2.0-0.noarch.rpm exampleware-2.0-0.noarch.rpm For more information, see Section 8.3, "Promoting a Content View" . 7.3. Creating a Life Cycle Environment Path To create an application life cycle for developing and releasing software, use the Library environment as the initial environment to create environment paths. Then optionally add additional environments to the environment paths. Procedure In the Satellite web UI, navigate to Content > Lifecycle Environments . Click New Environment Path to start a new application life cycle. In the Name field, enter a name for your environment. In the Description field, enter a description for your environment. Click Save . Optional: To add an environment to the environment path, click Add New Environment , complete the Name and Description fields, and select the prior environment from the Prior Environment list. CLI procedure To create an environment path, enter the hammer lifecycle-environment create command and specify the Library environment with the --prior option: Optional: To add an environment to the environment path, enter the hammer lifecycle-environment create command and specify the parent environment with the --prior option: To view the chain of the life cycle environment, enter the following command: 7.4. Removing Life Cycle Environments from Satellite Server Use this procedure to remove a life cycle environment. Procedure In the Satellite web UI, navigate to Content > Life Cycle Environments . Click the name of the life cycle environment that you want to remove, and then click Remove Environment . Click Remove to remove the environment. CLI procedure List the life cycle environments for your organization and note the name of the life cycle environment you want to remove: Use the hammer lifecycle-environment delete command to remove an environment: 7.5. Removing Life Cycle Environments from Capsule Server When life cycle environments are no longer relevant to the host system or environments are added incorrectly to Capsule Server, you can remove the life cycle environments from Capsule Server. You can use both the Satellite web UI and the Hammer CLI to remove life cycle environments from Capsule. Procedure In the Satellite web UI, navigate to Infrastructure > Capsules , and select the Capsule that you want to remove a life cycle from. Click Edit and click the Life Cycle Environments tab. From the right menu, select the life cycle environments that you want to remove from Capsule, and then click Submit . To synchronize Capsule's content, click the Overview tab, and then click Synchronize . Select either Optimized Sync or Complete Sync . CLI procedure Select Capsule Server that you want from the list and take note of its id : To verify Capsule Server's details, enter the following command: Verify the list of life cycle environments currently attached to Capsule Server and take note of the Environment ID : Remove the life cycle environment from Capsule Server: Repeat this step for every life cycle environment that you want to remove from Capsule Server. Synchronize the content from Satellite Server's environment to Capsule Server: 7.6. Adding Life Cycle Environments to Capsule Servers If your Capsule Server has the content functionality enabled, you must add an environment so that Capsule can synchronize content from Satellite Server and provide content to host systems. Do not assign the Library lifecycle environment to your Capsule Server because it triggers an automated Capsule sync every time the CDN updates a repository. This might consume multiple system resources on Capsules, network bandwidth between Satellite and Capsules, and available disk space on Capsules. You can use Hammer CLI on Satellite Server or the Satellite web UI. Procedure In the Satellite web UI, navigate to Infrastructure > Capsules , and select the Capsule that you want to add a life cycle to. Click Edit and click the Life Cycle Environments tab. From the left menu, select the life cycle environments that you want to add to Capsule and click Submit . To synchronize the content on the Capsule, click the Overview tab and click Synchronize . Select either Optimized Sync or Complete Sync . For definitions of each synchronization type, see Recovering a Repository . CLI procedure To display a list of all Capsule Servers, on Satellite Server, enter the following command: Note the Capsule ID of the Capsule that you want to add a life cycle to. Using the ID, verify the details of your Capsule: To view the life cycle environments available for your Capsule Server, enter the following command and note the ID and the organization name: Add the life cycle environment to your Capsule Server: Repeat for each life cycle environment you want to add to Capsule Server. Synchronize the content from Satellite to Capsule. To synchronize all content from your Satellite Server environment to Capsule Server, enter the following command: To synchronize a specific life cycle environment from your Satellite Server to Capsule Server, enter the following command:
