Installing Triton DataCenter on Equinix Metal

Triton offers a streamlined, fully automated installation experience using Equinix Metal.

Requirements

You will need:

Installing Triton

Create a Project

The first step in creating a Triton Cloud on Equinix Metal is to define a project. Your project will contain all of the resources allocated to your Triton Cloud.

To create a project, you will need to decide on a name.

triton-eqm-create.sh project -n My-Triton-Project

You may wish to extend your Triton Cloud to multiple data centers. If you do, you can choose to keep all datacenters in the same project or use separate projects for each project.

Create the headnode

The next step is to create the Triton headnode server. To create the headnode you will need the ID of the project you created, and to choos a facility, or datacenter location.

To list projects with packet:

packet project get

Ultimately the facility will need to meet your requirements. It's important to consider the geographic region, and the available capacity.

The following commands will list the available facilities, and avalable capacity by facility.

packet facility get
packet capacity get

Most information needed for the installation is obtained directly from the Equinix Metal metadata service. Howerver, the metadata doesn't provide all information that will be used by Triton. You can provide a supplemental JSON file with additional data. The format of this file is the same as the answers.json used by Triton, and supports a subset of keys. Supplemental answers are not required, and if not included, suitable defaults will be chosen. The following table shows the supported keys and the default if the key is not provided.

Key Default
company_name Empty string
datacenter_location Empty string
region_name Leading alpha characters of datacenter_name, which will be the Equnix Metal facility (e.g., iad)
dns_resolver1 8.8.8.8
dns_resolver2 8.8.4.4
dns_domain triton.local
mail_to root@localhost
mail_from support@
ntp_host 0.smartos.pool.ntp.org
root_password Randomly generated (you will need to use your Equinix Metal SSH keys to log in)
admin_password Randomly generated. You can find this password in /usbkey/config
update_channel release

Note: If you do not supply a root_password or admin_password, one will be randomly generated. In this case, you will only be able to ssh to the headnode using the SSH keys in your Equinix Metal account. If you provide neither SSH keys nor a root_password, you will not be able to log into the headnode. If you do not supply the admin_password you will need to change it before you can log into AdminUI. Use the sdc-useradm cli tool on the headnode to do this.

Here's an example JSON file that provides the supplemental data used by the installer.

{
  "company_name": "Weyland-Yutani",
  "region_name": "us-west",
  "datacenter_location": "Sillicon Valley, California",
  "dns_domain": "joyent.com",
  "mail_to": "root@example.com",
  "mail_from": "support@example.com",
  "root_password": "change this to something else",
  "admin_password": "seriously this is not a good password"
}

Note: Keys not provided in this file will use the defaults listed in the table above.

To create the headnode, use the following example:

triton-eqm-create.sh headnode -p bec6b78a-a91f-11eb-b5ef-cfcd9128c9eb \
    -f sv15 -a supplemental.json

The script will do the following:

Once the server is provisioned the script will emit the location of the "SOS" console. This allows you to connect to the server's serial console to watch progress, or troubleshoot if necessary.

You can watch an example of the entire process below.

Post-install Tasks

After server installation is complete you can ssh to the headnode. Use the packet-cli or Equinix Metal web interface to determine your headnode's IP address.

ssh -l root 198.51.100.34

See the Triton On-Premesis documentation for additional post-install setup tasks.

Common tasks include:

Create Additional Compute Nodes

Creating additional compute capacity can be done at any time after the headnode is installed, can be expanded on-demand as needed, and this process can be completed in about 20 minutes.

The following command shows an example of creating a compute node.

triton-eqm-create.sh computenode -p <project_id> -f sv15

This will do the following:

After the server has fully booted you will need to run sdc-server setup. When the server has finished setup, copy and paste the networking commands emitted by the triton-eqm-create.sh command. In order to verify that networking has been properly configured, reboot the server a final time to ensure everything comes up properly.

If you have an external network pool, add the server's external network to the pool, and the server is ready for use.
