Node upgrade instructions

Introduction

Node upgrades are required for all collators when a new node version is released. It is very important that all nodes on the network maintain the same node version.
We provide our partners with the following installables.
  • Docker Image
  • .deb Ubuntu package for Ubuntu 20/22
  • Precompiled binary

Docker image

Always use the image with the “latest” tag when you upgrade, that will have the recently pushed docker image.
docker pull pendulumchain/amplitude-collator:latest
