Nomad is a cluster manager and scheduler designed for microservices and batch processing workloads. In this tutorial, we'll go over the steps to install Nomad on FreeBSD Latest.
Before you begin, make sure you have the following prerequisites:
Nomad requires some dependencies to be installed on your FreeBSD system. We'll use the pkg package manager to install them.
To update the package repository, run the following command:
sudo pkg update
Next, install the dependencies:
sudo pkg install -y curl unzip
Now, we'll download the Nomad binary from the official website using curl.
sudo curl -Lo nomad.zip https://releases.hashicorp.com/nomad/<VERSION>/nomad_<VERSION>_freebsd_amd64.zip
Replace <VERSION> with the version of Nomad you want to install. You can check the latest version on the Nomad downloads page.
Once the download is complete, extract the binary:
sudo unzip nomad.zip -d /usr/local/bin/
Nomad needs a configuration file to run. We'll create a basic configuration file at /etc/nomad.hcl.
sudo touch /etc/nomad.hcl
sudo nano /etc/nomad.hcl
Add the following contents to the configuration file:
data_dir = "/var/nomad"
bind_addr = "<IP_ADDRESS>"
advertise {
http = "<IP_ADDRESS>:4646"
rpc = "<IP_ADDRESS>:4647"
serf = "<IP_ADDRESS>:4648"
}
consul {
address = "<CONSUL_ADDRESS>"
}
Replace <IP_ADDRESS> with the IP address of your server and <CONSUL_ADDRESS> with the address of your Consul server if you have one.
Save and close the file.
We're now ready to start Nomad. We'll use systemd to manage the process.
Create a nomad.service file:
sudo touch /etc/systemd/system/nomad.service
sudo nano /etc/systemd/system/nomad.service
Add the following contents to the service file:
[Unit]
Description=Nomad
After=consul.service
[Service]
Type=simple
ExecStart=/usr/local/bin/nomad agent -config=/etc/nomad.hcl
ExecReload=/bin/kill -HUP $MAINPID
Restart=on-failure
[Install]
WantedBy=multi-user.target
Save and close the file.
Reload systemd:
sudo systemctl daemon-reload
Enable and start the nomad service:
sudo systemctl enable nomad
sudo systemctl start nomad
Check the status of the service:
sudo systemctl status nomad
If everything was successful, you should see Active: active (running).
You've successfully installed Nomad on FreeBSD Latest. Now you can use it to manage your microservices and batch processing workloads.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
