Upgrading Docker
The only case where special attention is required is for GPU nodes in the development cluster (or any other edge case that has a special configuration contained in the /etc/docker/daemon.json configuration file.
The general procedure is as follows:
- copy the /etc/docker/daemon.json file aside
- upgrade docker
- replace the /etc/docker/daemon.json file
- restart docker
These steps are implemented for the dev cluster in the 'update-docker.sh' script in the k8s-admin repository on GitLab.
