Upgrade an Octez node

As you may know, Tezos is an evolving blockchain. Through its on-chain governance mechanism, Tezos smoothly evolves to become more secure and scalable over time.

The following commands help to upgrade your node to the latest Octez version.

Docker and docker-compose

Upgrade the docker image

To upgrade your node to the latest Octez version, run the lastest image. Note that if you run the latest image, restarting your container is sufficient.
