Mount a Presearch node on TFGrid3 using VM

The fastest way to mount a Presearch node on TFGrid3 is inside a VM.

Steps :

• Set up a VM, see here. It is recommended to reserve a fix IP. You can also try out the planetary network (so reserve a VM without public IP), as long as the node you select is connected to the internet through an IPv4 address that isn't used yet for a Presearch node, you don't explicitly need to reserve a public IPv4 address. However, the planetary network is still in beta phase and might generate performance issues.
• 1 CPU is enough for a PRE node. As we still need to install Docker on the VM before deploying a PRE node, please choose 8192 memory size.
• Once your VM is set up, SSH into our machine.

For the VM having an IP address you can enter the terminal command

ssh root@185.206.122.162

If you didn't reserve a public IPv4 address, you can ssh into your machine using the IPv6 address. Peopl doing this, should however first set up their identity in the Planetary Network with Yggdrasil. See here to know how to do this.

ssh root@300:aa1b:e91b:720f:ae5f:8991:6df8:1ec9

Now you have an empty VM, also Docker still needs to be installed.

Execute the following commands inside your VM :

apt update ; 
apt install sudo ;
sudo apt install apt-transport-https ca-certificates curl software-properties-common ;
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - ;
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable" ; 

Finally, install Docker. The Ubuntu machine does not come with systemd. The following does the trick :

apt-get install docker-ce docker-ce-cli containerd.io
apt-cache madison docker-ce

dockerd &

Once Docker is set up, you can launch the PRE node instructions on your VM:

docker stop presearch-node ; docker rm presearch-node ; docker stop presearch-auto-updater ; docker rm presearch-auto-updater ; docker run -d --name presearch-auto-updater --restart=unless-stopped -v /var/run/docker.sock:/var/run/docker.sock presearch/auto-updater --cleanup --interval 900 presearch-auto-updater presearch-node ; docker pull presearch/node ; docker run -dt --name presearch-node --restart=unless-stopped -v presearch-node-storage:/app/node -e REGISTRATION_CODE=$YOUR_REGISTRATION_CODE_HERE presearch/node ; docker logs -f presearch-node

And you're done !
