$ sudo apt-get install -y python-pip

$ git clone https://git.onap.org/multicloud/k8s/

$ cd hosting_providers/vagrant

$ ./installer.sh | tee kud_installer.log


Since the baremetal setup and vagrant deployment use the same installer script to complete deployment some of the ansible roles within Baremetal and Vagrant are conflicting. Until this is resolved please cherry-pick this patch to get a successful deployment.

KUD consumes kubespray for provisioning a Kubernetes base deployment. As part of the deployment process, this tool downloads and configures kubectl binary.

Ansible uses SSH protocol for executing remote instructions. The following instructions create and register ssh keys which avoid the usage of passwords.

Generate ssh-keys

$ echo -e "\n\n\n" | ssh-keygen -t rsa -N ""
$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
$ chmod og-wx ~/.ssh/authorized_keys

Enabling Nested-Virtualization

...

Enable nested virtualization 

$sudo ./node.sh

Deploying KUD Services

Finally, the KUD provisioning process can be started through the use of the installer.sh bash script. The output of this script is collected in the kud_installer.log file for future reference.

Bring the cluster up by running the following

$ ./installer.sh | tee kud_installer.log

Running test cases

The kud/tests folder contain the health check scripts that guarantee the proper installation/configuration of Kubernetes add-ons. Some of the examples for test scripts are virtlet.sh, multus.sh, ovn4nfv.sh etc.
