6.2. Linode.com

Existing machines can use the join-up.sh script to join a DRP endpoint without having to go through a netboot. The Linode integration uses this feature to manage virtual machines.

These instructions can also be adapted to work on GCE or other cloud infrastructure.

The following video shows the process: https://youtu.be/e4Vp3quzlhM

6.2.1. Stackstripts

You can use public Stackscripts to quickly setup your DRP endpoint and attach nodes. They perform the same basic tasks as the code below.

1. Create an endpoint using zehicle/drp and supply your version and password. 1. Verify that the DRP Endpoint is available at the https://[endpoint_ip]:8092 1. Use zehicle/drp-node to attach nodes to the endpoint. You’ll need to know the endpoint_ip. 1. profit.

6.2.2. Install DRP in Linode

You can use the Amazon Linux AMI. While more is recommended, make sure that you have at least 1 GB of RAM. You should open ports 8091 and 8092 to access the DRP server.

#!/bin/bash
# <UDF name="drp_version" Label="Version to Install" default="stable" example="tip, stable, v3.13, ..." />
# <UDF name="drp_password" Label="Admin Password" default="r0cketsk8ts" example="password" />

### Install DRP from Tip
curl -fsSL get.rebar.digital/tip | bash -s -- install --systemd --version=$DRP_VERSION --drp-password=$DRP_PASSWORD --ipaddr=[DRP public address]

### Now open the right firewall ports for DRP
firewall-cmd --permanent --add-port=8092/tcp
firewall-cmd --permanent --add-port=8091/tcp
firewall-cmd --reload

### Install Content and Configure Discovery
drpcli catalog item install task-library --version=$DRP_VERSION
drpcli catalog item install drp-community-content --version=$DRP_VERSION
drpcli workflows create '{"Name": "discover-linode", "Stages":
  ["discover", "network-firewalld", "runner-service", "complete"]
}'
drpcli profiles set global param "network/firewalld-ports" to '[
  "22/tcp", "6443/tcp", "8379/tcp",  "8380/tcp", "10250/tcp"
]'
drpcli prefs set defaultWorkflow discover-linode unknownBootEnv discovery

Once the system is online, you can access DRP using https://[DRP public address]:8092.

6.2.3. Join a machine to a DRP Endpoint in Linode

Once you have a DRP endpoint installed in Linode

#!/bin/bash
# <UDF name="drp_ip" Label="IP Address of the DRP Endpoint" default="" example="192.168.1.100" />
# <UDF name="drp_port" Label="Provisioning Port of the DRP Endpoint (not API port)" default="8091" example="8091" />
# <UDF name="open_ports" Label="Ports to open on the machine" default="22 2379 2380 6443 10250" example="22 6443 10250" />

for PORT in ${OPEN_PORTS}; do
   firewall-cmd --permanent --add-port=${PORT}/tcp
done
firewall-cmd --reload

timeout 300 bash -c 'while [[ "$(curl -fsSL -o /dev/null -w %{http_code} ${DRP_IP}:${DRP_PORT}/machines/join-up.sh)" != "200" ]]; do sleep 5; done' || false

curl -fsSL ${DRP_IP}:${DRP_PORT}/machines/join-up.sh | sudo bash --
