Relay node instructions

Before building

Add new user to remote server

useradd -m -s /bin/bash cardano

passwd cardano

usermod -aG sudo cardano

Copy ed25519 public keys from local to remote server

ssh-copy-id -i $HOME/.ssh/<keyname>.pub cardano@server.public.ip.address

Update sshd_config file

sed -i '/ChallengeResponseAuthentication/d' /etc/ssh/sshd_config
sed -i '/PasswordAuthentication/d' /etc/ssh/sshd_config
sed -i '/PermitRootLogin/d' /etc/ssh/sshd_config
sed -i '/PermitEmptyPasswords/d' /etc/ssh/sshd_config

echo "ChallengeResponseAuthentication no" >> /etc/ssh/sshd_config
echo "PasswordAuthentication no" >> /etc/ssh/sshd_config
echo "PermitRootLogin prohibit-password" >> /etc/ssh/sshd_config
echo "PermitEmptyPasswords no" >> /etc/ssh/sshd_config

Validate sshd config

sudo sshd -t

Restart sshd service

sudo systemctl restart sshd

Remember to replace in ./prometheus/prometheus.yml with the proper ip addresses

Build cardano node docker image

  • replace <block-producer-ip-address> with the IP Address of the block producer node
  • replace <block-producer-port> with the Port number of the block producer node
docker compose build \
    --build-arg BLOCKPRODUCING_IP=<block-producer-ip-address> \
    --build-arg BLOCKPRODUCING_PORT=<block-producer-port>

Upgrade Node

docker compose down

docker compose build \
    --build-arg BLOCKPRODUCING_IP=<blockproducing-ip-address> \
    --build-arg BLOCKPRODUCING_PORT=<blockproducing-port>

or

docker compose build \
    --no-cache \
    --build-arg BLOCKPRODUCING_IP=<blockproducing-ip-address> \
    --build-arg BLOCKPRODUCING_PORT=<blockproducing-port>

Access to relay node

docker exec -it cardano-node-relay bash
