Kubernetes Cookbook - Second Edition

How it works...

As mentioned earlier, let's bump the nginx image version from 1.11.0 to 1.12.0. There are two ways to change the container image: use the kubectl set command, or update YAML then use the kubectl apply command.

Using the kubectl set command is quicker and there is better visibility when using the --record option.

On the other hand, updating YAML and using the kubectl apply command is better to preserve the entire Deployment YAML configuration file, which is better when using a version control system such as git.
