Adapting kubespray to deploy k8s within Embassy cloud portal

  • get latest kubespray
  • deploy
  • start k8s-galaxy
  • trigger k8s-galaxy workflow execution

after checkout and getting the latest kubespray, recreating some symlinks might be necessary:

  • .//extra_playbooks/roles -> ../roles
  • .//extra_playbooks/inventory -> ../inventory
  • .//contrib/terraform/group_vars -> ../../inventory/group_vars
  • .//contrib/terraform/openstack/hosts -> ../terraform.py
  • .//contrib/terraform/openstack/group_vars -> ../../../inventory/group_vars
  • .//contrib/network-storage/glusterfs/group_vars -> ../../../inventory/group_vars
  • .//contrib/network-storage/glusterfs/roles/bootstrap-os -> ../../../../roles/bootstrap-os
  • ./kubespray ->

troubleshooting

in case of ssh connection issues check if there are still ssh folders in /tmp lingering

rm /tmp/kubespraytest-k8s-*

also cleanse known_hosts from bastion public_ip

to bring up the deployment

ostack/deploy.sh

before that, except for sourcing the openstack credentials, the following exports might be needed:

set environment variables used by scripts in cloud-deploy/

export PUBLIC_KEY="" export PRIVATE_KEY="" export PORTAL_DEPLOYMENTS_ROOT="$PWD/deployments" export PORTAL_APP_REPO_FOLDER="$PWD" export PORTAL_DEPLOYMENT_REFERENCE="deployment-ref-ubuntu"

to destroy the deployment

use

terraform destroy --force --input=false --state=deployments/deployment-ref-ubuntu/terraform.tfstate
