System Requirements
This document includes information about the hardware, containers, prerequisite software, supported operating system, and database requirements with component level detail for the HCL DevOps Deploy (Deploy).
Getting Started
Quickly become productive with HCL DevOps Deploy (Deploy).
Installing
An HCL DevOps Deploy (Deploy) installation consists of a Deploy server, a database server, and at least one agent.
- Firewall and communication configuration
  This topic describes the communication between the HCL DevOps Deploy (Deploy) components, the firewall, and the ports involved in the communication.
- Installing the server database
  You must install a supported database before you install HCL DevOps Deploy (Deploy). The database parameters such as database name, database username, and connection information are required at the time of Deploy installation.
- Installing the DevOps Deploy server
  The server provides services such as the user interface used to configure application deployments, the security service, and the artifact repository, among others. Installing the server involves specifying configuration information for the server, such as the ports that the server uses.
- Installing with Kubernetes
  The HCL DevOps Deploy (Deploy) server can be installed in a cloud-based environment, as a containerized server cluster, managed by Kubernetes. Deploy works with Kubernetes to simplify application deployment and manage versions in the containers.
- Installing agents
  You can install agents from the server or from the command line on the agent system. To configure a failover server for an agent, you must install the agent from the command line.
- Installing agent relays
  An agent relay is a communication proxy for agents that are located behind a firewall or in another network location. You can install agent relays in interactive mode or in silent mode.
  - Installing agent relays in interactive mode
    Installing an agent relay from the command line involves running a batch file or shell script and specifying information about the agent relay.
  - Installing agent relays in silent mode
    In silent mode, you specify the installation properties in a text file and then run the agent relay installation without command-line prompts.
  - Installing an agent relay in a Kubernetes cluster
    An HCL DevOps Deploy (Deploy)agent relay automates application deployments through your environments. Relays are especially good for coordinating environments with numerous agents. You can connect several agents outside the firewall to the server with a single relay.

    - Installing agent relays as services using systemd
      You can find information about the steps to install agent relays to run as systemd services. After you configure an agent relay using the systemd service, the agent relay automatically restarts when it stops abruptly.
    - Uninstalling agent relay services using systemd
      You can uninstall an agent relay running as a systemd service when the agent relay is no longer required.
  - Agent relay installation properties
    You can find the list of HCL DevOps Deploy (Deploy) agent relay properties that are used during the installation process.
- Starting DevOps Deploy
  Both UNIX™ and Windows™ installations require the HCL DevOps Deploy (Deploy) server and at least one agent. Also, make sure that the appropriate driver is installed and configured.
- Installing and uninstalling test fixes (patches) from the server
  Test fixes are provided to correct specific issues. They are applied to the server as patches.

Installing agent relays as services using systemd

You can find information about the steps to install agent relays to run as systemd services. After you configure an agent relay using the systemd service, the agent relay automatically restarts when it stops abruptly.

Before you begin

You must have ensured the following:

The server is running.
The agent relay is installed in the host machine.

About this task

Installing agent relays by using the systemd service helps you to ensure that the agent relay runs automatically on the system startup and restarts the agent relay automatically if it stops.

Procedure

Log in to the agent relay host machine.
Locate the product systemd directory by using the following command:
```
cd <install-directory>/bin/systemd
```
Edit the unit file and specify the User and Group values that will run the agent relay.
User: The name of the user who will run the agent relay.
Group: The name of the group associated with the user.
Your interface might look like the following example:
```
After=network.target

[Service]
# These must be changed (or removed) to set the appropriate agent account.
User=ec2-user
Group=ec2-user
# Modifications to these are not supported.
```
Note: When you customize the user and group values, you must update the ownership of the agent relay files to match with the updated User and Group values.

Install the service unit file by using the following commands:

sudo cp devops-deploy-agentrelay.service /etc/systemd/system
chmod 664 /etc/systemd/system/devops-deploy-agentrelay.service
chown root:root /etc/systemd/system/devops-deploy-agentrelay.service
systemctl daemon-reload

Enable the service to start automatically on system startup by using the following command:
```
sudo systemctl enable devops-deploy-agentrelay
```
Start the agent relay as service by using the following command:
```
sudo systemctl start devops-deploy-agentrelay
```

Results

You installed the agent relay to run as a systemd service.

What to do next

You must run the following command to verify whether the agent relay is running as a systemd service:

sudo systemctl status devops-deploy-agentrelay
