Supported by Kubernetes container runtime?

Question

Docker

Good afternoon.
What is the default container runtime after installation that Kubernetes uses? Docker's?
And how can I change it to use cri-o or another container runtime?

Answer 1

When you install what you put, it will stand. This is if you set it with handles, in kubespray - you specify it in the configs.
To change the runtime:
1. stop the docker, kublet
2. Install cri-o, check its service
3. Specify cri-o
in the kublet parameters 4. Change the parameters of the network driver
5. Start the kublet and cri-o services
6. Wait for it to finish cluster.
