You must specify at least one annotation operation. For example, to set annotations on the cluster
with identifier '123':

{{ binary }} annotate cluster 123 my-annotation=my-value your-annotation=your-value

To remove an annotation, use the annotation name followed by a '-' character:

{{ binary }} annotate cluster 123 my-annotation-

Use the '--type' flag to specify a type other than string. For example, to set a boolean
annotation:

{{ binary }} annotate cluster 123 my-flag=true --type bool

Use the '--help' option to get more details about the command.
