Deploying via kubernetes/contrib/ansible

See: https://github.com/nds-org/ndslabs-deploy-tools

...

These Ansible scripts are currently specific to NCSA / SDSC, but with little manual effort can be expanded to accommodate other OpenStack installations at other sites.

...

Deploying via kube-up.sh

See: https://kubernetes.io/docs/getting-started-guides/openstack-heat/

Steps so farFeatures:

Usage

  1. docker run -it -v /home/core/private:/private bodom0015/k8-openstack-cli:NDS-767
  2. source /private/NDSLabsDev-openrc.sh
    1. Enter password
  3. yum -y install curl wget which openssh
  4. ssh-keygen -t rsa
    1. Accept all defaults
  5. export KUBERNETESexport KUBERNETES_PROVIDER='openstack-heat'; curl -sS https://get.k8s.io | bash cd /kubernetes && export PATH=$PATH$PATH:/kubernetes/client/bin/
  6. ssh-keygen -t rsa
    1. Accept all defaults
  7. export FIXEDexport EXTERNAL_NETWORK=ext-net FIXED_NETWORK_CIDR='192.168.100.0/24'24

  1. heat && cd /kubernetes && ./cluster/kube-up.sh

This will create a stack named kubernetes under the Horizon dashboard's Orchestration → Stacks view. Here, you can check the progress of the creation task by choosing a Stack and viewing its Resources tab.

The whole process takes about 10 minutes to finish. You should see instances being spun up in the project's Compute → Instances view.

You should see the following outputAt this point, I got an error:
