Add Watch API support for the pods page
What does this MR do and why?
This MR adds the Kubernetes Watch API support for the pods page. It should work similarly to the Kubernetes section on the environments page -> We first request static data and if it's there we proceed by subscribing to the events stream that the Kubernetes API provides.
Screenshots or screen recordings
The data is auto-updated when I delete some pods and wait for the system to heal:

How to set up and validate locally
- Enable the
k8s_dashboard
feature flag
Feature.enable(:k8s_dashboard)
-
Enable KAS on your GDK (steps 1-2 from the guide).
-
Visit the Project -> Infrastructure -> Kubernetes clusters page and create an agent following the instruction from the modal.
- Select the "Connect a cluster" button
- The modal should pop up
- In the modal select "Select an agent or enter a name to create new"
- You probably won't have any configured agents to show up in the list, create a new one by typing the name of your choice
- The button should appear at the bottom of the list saying "Create agent:
<your-agent-name>
" - Select the button and click "Register" in the next view.
- Save the token to use it in the next point.
-
Add the following configuration inside your project in
.gitlab/agents/<your-agent-name>/config.yaml
for the user_access agent:gitops: manifest_projects: - id: <your-group>/<your-project> user_access: access_as: agent: {} projects: - id: <your-group>/<your-project-to-share-agent-with>
-
Note that the shared agents should be connected to the cluster in order to appear in the list. Please follow points 3-8 from the guide and then the (Optional) Deploy the GitLab Agent (agentk) with k3d section to create a local cluster and connect your agent with the cluster.
