Modeling software deployment
Modeling software deployment in HCL Launch includes configuring components and component processes and adding those components to applications. Then, you use processes to deploy the components to environments.
- Components
  Components represent deployable items along with user-defined processes that operate on them, usually by deploying them.
- Resources
  A resource is a logical deployment target that typically resolves to an agent and a user-defined construct that is based on the architectural model of HCL Launch.
- Applications
  Applications are responsible for bringing together all the components that must be deployed together.
- Application environments
  An environment is a user-defined collection of resources that hosts an application.
- Application templates
  With an application template, you can save and reuse a collection of resources, environments, processes, and tagged components or component templates to create a standardized application.
- Application processes
  Application processes, like component processes, are created with the process editor. You use application processes to deploy or to roll back components.
- Application blueprints
  An application blueprint maps application components to a resource template. When you create an environment or provision one from the cloud, you can use the blueprint as a model.
- Snapshots
  A snapshot is a collection of specific versions of components and processes. Typically, a snapshot represents a set of component versions that are known to work together. In most cases, snapshots include all of the components in an application.
- Creating manual application tasks
  A manual application task interrupts an application process until manual intervention is done. To create a manual task, add a manual step to an application process and select a notification template.
- Approval process
  Approval processes are created when you want a manual intervention in executing a particular task or process step.
- Inventories
  You use different inventories to track installed components and properties in HCL Launch elements.
- Processes
  Processes are automated tasks that run on agents.
  - Process step types and logic
    When you design processes, you use different kinds of process steps and joining techniques. You can assign properties to process steps and use them to control step execution.
  - Component processes
    A component process is a series of user-defined steps that operate on a component's artifacts. Each component has at least one process that is defined for it and can have several.
  - Application processes
    You can use application processes to deploy or to roll back components.
  - Generic processes
    Generic processes are not specific to a particular component and can be used in any number of applications. They are like general purpose processes. You can use generic processes to download and install packages on the system or perform other configuration management related tasks such as configuring SSH or completing FTP tasks. With a generic process, for example, you can update Linux agents that were recently installed by using SSH to run as a service on a Linux computer. Linux agents cannot be updated in this way during a remote installation.
  - Editing processes
    In the process editor you organize the steps in a process, specify their properties, and connect them to each other.
  - Working on processes in safe edit mode
    Safe editing enables you to test component processes before making them available in normal environments. Make updates to your component process, test those updates safely, and then promote to a new version when you are ready.
  - Running processes
    The way you run a process is different for each type of process.
  - Adding process properties
    A process property provides a way to add user-supplied information to a process. A running process can prompt users for information and then incorporate it into the process. For example, if the process entails authenticating with another server, you can require that a user enter an ID and a password for the process to continue. Properties are defined in the Edit Property dialog box.
  - Copying process steps
    You can copy and paste process steps in all process types: component, application, approval, and generic.
  - Manage process step authentication
    Use token restrictions to manage process step authentication.
  - User impersonation for process steps
    HCL Launch can use user impersonation when an agent must run a command for which it might not otherwise have permission, or when a specific user must be employed for a process.
  - Process steps: Reference
    Application processes, component processes, and generic processes are created with the process editor.
- Statuses
  Create and apply statuses to track component inventory states or to track component versions in environments and resources.
- Properties
  Properties are variables that store information about many different elements, including components, environments, processes, and applications. You can also set global properties for the system.
- Tags
  A tag is a user-defined, shared, short label that you use to classify, view, and conduct operations on objects such as applications, components, agents, and resources.

Processes

Processes are automated tasks that run on agents.

There are three types of processes:

Generic processes run outside the context of components or applications. Generic processes are shown on the top-level Processes tab. You can use generic processes in these instances, for example:
- In conjunction with a number of different component processes that do not fit well into a component template
- When you want to run processes that directly affect HCL Launch agents that are unrelated to component, such as changing the agent configuration
Application processes run within the context of applications. In many cases, application processes call component processes. For example, an application process can call the component processes that deploy their associated components.
Component processes run tasks on a single component, such as deploying it, uninstalling it, or running configuration tasks on it.

Processes are lists of steps and connections between those steps. Each step is an individual command that runs on a target computer. Steps can manipulate files, run system commands, download files, and run programs. Plug-ins contribute most of these steps; plug-ins are available that work with many different types of software. For information about steps that are provided by plug-ins, see the documentation for the individual plug-in in the UrbanCode Plug-ins site: https://urbancode.github.io/IBM-UCx-PLUGIN-DOCS/UCD

You use the process editor to work with processes. See Editing processes.

Each time you request a process, the server keeps a log of information about the process and the individual logs from each step. To download these logs, open the process request and click Download All Logs.
