Getting Started with kops on OpenStack

WARNING: OpenStack support on kops is currently alpha meaning it is in the early stages of development and subject to change, please use with caution.

Create config file

The config file contains the OpenStack credentials required to create a cluster. The config file has the following format:

[Default]
identity=<OS_AUTH_URL>
user=mk8s=<OS_USERNAME>
password=<OS_PASSWORD>
domain_name=<OS_USER_DOMAIN_NAME>
tenant_id=<OS_PROJECT_ID>

[Swift]
service_type=object-store
region=<OS_REGION_NAME>

[Cinder]
service_type=volumev3
region=<OS_REGION_NAME>

[Neutron]
service_type=network
region=<OS_REGION_NAME>

[Nova]
service_type=compute
region=<OS_REGION_NAME>

Environment Variables

It is important to set the following environment variables:

export OPENSTACK_CREDENTIAL_FILE=<config-file> # where <config-file> is the path of the config file
export KOPS_STATE_STORE=swift://<bucket-name> # where <bucket-name> is the name of the Swift container to use for kops state

# TODO(lmb): Add a feature gate for OpenStack
# this is required since OpenStack support is currently in alpha so it is feature gated
# export KOPS_FEATURE_FLAGS="AlphaAllowOpenStack"

Creating a Cluster

# coreos (the default) + flannel overlay cluster in Default
kops create cluster --cloud=openstack --name=my-cluster.k8s.local --networking=flannel --zones=Default --network-cidr=192.168.0.0/16
# Not implemented yet...
# kops update cluster my-cluster.k8s.local --yes

# to delete a cluster
# Not implemented yet...
# kops delete cluster my-cluster.k8s.local --yes

Features Still in Development

kops for OpenStack currently does not support these features:

cluster create (servers, servergroups, load balancers, and DNS are not implemented yet)
cluster delete
state delete (fails due to unimplemented methods)
