Step 2: Configure Nomad

Before starting the Nomad server or client, we need to configure it. We will create a nomad.hcl file in the /etc/nomad.d directory with the required configurations. Follow the below steps to configure Nomad.

1. Create a directory for storing the Nomad configuration file:

   sudo mkdir -p /etc/nomad.d
   

2. Create a nomad.hcl file using any text editor of your choice and add the below configurations.

   # Configuration for Nomad server or client
   data_dir = "/var/lib/nomad"
   
   # Enable HTTP and RPC API
   api_addr = "http://0.0.0.0:4646"
   enable_api = true
   
   # Specify Consul server for service discovery
   consul {
     address = "127.0.0.1:8500"
     retry_join = ["192.168.0.1", "192.168.0.2"]
   }
   

   Here, we have enabled the HTTP and RPC API, specified the Consul server address for service discovery, and set the data directory to /var/lib/nomad.

3. Set the ownership and permissions for the nomad.hcl file using the command:

   sudo chown root:root /etc/nomad.d/nomad.hcl
   sudo chmod 644 /etc/nomad.d/nomad.hcl
   

Congratulations! You have successfully configured Nomad on Clear Linux Latest.
