A GitPod Workspace for Openstack and Kubernetes

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 and Swift clients

• For Kubernertes: Kubectl, Helm, Verlero & Kustomize.

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

Configuring Openstack

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

• Copying the content of your &lt;<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:

1- Copying the into your workspace

Copy your kubeconfig into a ~/.kube/config file in your Gitpod workspace.

nano ~/.kube/config

2- Adding your kubeconfig as a Gitpod secret

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. Copy Kubeconfig (base64 format) to Gitpod

   

3. Configure the project to extract kubeconfig, by editing your .gitpod.yml file and add this following content:

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