kops create cluster

kops create cluster <clustername> creates a cloud specification in the registry. It will not create the cloud resources unless you specify --yes, so that you have the chance to kops edit them. (You will likely kops update cluster after creating it).

kops update cluster

kops update cluster <clustername> creates or updates the cloud resources to match the cluster spec.

It is recommended that you run it first in 'preview' mode with kops update cluster --name <name>, and then when you are happy that it is making the right changes you runkops update cluster --name <name> --yes.

kops get clusters

kops get clusters lists all clusters in the registry.

kops delete cluster

kops delete cluster deletes the cloud resources (instances, DNS entries, volumes, ELBs, VPCs etc) for a particular cluster. It also removes the cluster from the registry.

It is recommended that you run it first in 'preview' mode with kops delete cluster --name <name>, and then when you are happy that it is deleting the right things you run kops delete cluster --name <name> --yes.

kops version

kops version will print the version of the code you are running.

Other interesting modes:

  • Build a terraform model: --target=terraform The terraform model will be built in out/terraform

  • Specify the k8s build to run: --kubernetes-version=1.2.2

  • Run nodes in multiple zones: --zones=us-east-1b,us-east-1c,us-east-1d

  • Run with a HA master: --master-zones=us-east-1b,us-east-1c,us-east-1d

  • Specify the number of nodes: --node-count=4

  • Specify the node size: --node-size=m4.large

  • Specify the master size: --master-size=m4.large

  • Override the default DNS zone: --dns-zone=<my.hosted.zone>
