Gitpod GitPod Workspace for OVHcloud Openstack and Kubernetes

A working Gitpod setup to work with OVHcloud Openstack and Managed Kubernetes. The workspace includes:

• For Openstack: Openstack, Nova, Cinder, Neutron, Swift, Glance, Octavia, Mistral, Barbican and ironic clients, awscli

• For Kubernetes: Kubectl, Helm, Velero & Kustomize.

To open the workspace, simply click on the Open in Gitpod button, or use this link.

If you prefer manually setting up the variables, you can also source the scripts/setOpenstack.sh file.

source ./scripts/setOpenstack.sh

Configuring Openstack

To configure openstack, you need to setup Openstack authentication variables. There are two ways to do it:

• Copying the content of your <user_name>-openrc.sh file into a openrc.sh file in your workspace and source it:

  source ./openrc.sh

• Using GitPod variables to define the following environment variables:

  # Keystone v2.0
  OS_AUTH_URL=<AUTH_URL /v2.0>
  OS_USERNAME=<USERNAME>
  OS_REGION_NAME=<REGION>
  
  # Keystone v3
  OS_AUTH_URL=<AUTH_URL /v3>
  OS_USERNAME=<USERNAME>
  OS_PROJECT_ID=<PROJECT_ID>
  OS_PROJECT_NAME=<PROJECT_NAME>
  OS_REGION_NAME=<REGION_NAME>
  OS_DOMAIN_NAME=<DOMAIN_NAME OR OS_USER_DOMAIN_NAME>

  Never add OS_PASSWORD as a Gitpod variable, the workspace will ask you for it after booting up.

Configuring Kubeconfig

To administrate your Kubernetes cluster from Gitpod, you need to add your Kubeconfig to your Gitpod workspace. There are two ways to do it:

• Copying the content of your kubeconfig file into a ~/.kube/config file in your Gitpod workspace.

  nano ~/.kube/config

• Adding your kubeconfig as a Gitpod

Gitpod supports encrypted, user-specific environment variables. They are stored as part of your user settings and can be used to set access tokens, or pass any other kind of user-specific information to your workspaces.

To do it you need to follow this steps:

1. Convert Kubeconfig to base64

   cat kubeconfig | base64 -w 0

2. Using GitPod variables to define a K8S_CTX variable with the content of your kubeconfig in base64 as value:

   

   This project is configured to extract the kubeconfig from the value of K8S_CTX and inject it in the ~/.kube/config file:

   .gitpod.yml:

   tasks:
       - name: Set K8s context
       command: echo $KUBECONFIG | base64 -d > ~/.kube/config
