This guide explains how to configure the
OpenStack Cloud Provider for Kubernetes
in your Google Distributed Cloud cluster. The OpenStack Cloud Provider must be
configured to expose Kubernetes Services using the
OpenStack LBaaS.
Prerequisites
This guide assumes that you have an Google Distributed Cloud cluster running in
your OpenStack environment with a setup similar to what is explained in the
Deploy Google Distributed Cloud on OpenStack guide. Please
follow that guide first before trying these steps.
Configure the provider
The following section assumes that you are starting from a terminal window in
your local workstation.
Source the OpenStack client configuration (openrc) file. You can download
it from the OpenStack WebUI.
sourcePATH_TO_OPENRC_FILE/openrc
Create the configuration file for the OpenStack Kubernetes Cloud Provider.
OS_AUTH_URL, OS_USERNAME,
OS_PASSWORD: These variables should be already set
in the environment by source-ing the openrc file. Thus, they will be
automatically picked up.
PUBLIC_NETWORK_ID: This is the publicly accessible
network in your OpenStack deployment from which Floating IPs are
allocated. It is from this network the LoadBalancer IPs for the
Kubernetes services will be assigned. You can use a command similar to
this one
to fetch this IP from your OpenStack environment.
ABM_NETWORK_SUBNET_ID: This is the subnet on the
private network in your OpenStack deployment from which IPs are allocated
for the VMs running Google Distributed Cloud. You can use a command similar
to
this one
to fetch this IP from your OpenStack environment.
Fetch the public floating IP address of the abm-ws VM.
exportOPENSTACK_IPS=$(openstackfloatingiplist--tags=abm_ws_floatingip-fjson)exportFLOATING_IP=$(jq-c'.[]."Floating IP Address"' <<< $OPENSTACK_IPS|tr-d'"')
Copy the cloud.conf file into the abm-ws VM in OpenStack.
scp./cloud.confubuntu@$FLOATING_IP:~
Log in securely into the abm-ws VM via SSH and log in as a root user.
The root user as configured by the
Terraform scripts
is abm.
sshubuntu@$FLOATING_IP
sudo-uabm-i
Copy the cloud.conf files into the $HOME directory of the root user.
cp/home/ubuntu/cloud.conf$HOME
Create a Kubernetes Secret with the configuration.

# store the provider configurations as a Kubernetes secret
kubectlcreatesecret-nkube-systemgenericcloud-config--from-file=cloud.conf

You can notice a new OpenStack Load Balancer being created in OpenStack by
visiting the OpenStack WebUI.
