Problem:
When connecting to the pod or cluster terminal from the Devtron dashboard on an ingress with gce class in a GKE cluster, the connection gets disconnected after every 30 seconds. This issue is caused by the default timeoutSec value of 30 seconds in the backendConfig.
Solution:
To resolve this issue, you can increase the timeoutSec value in the backendConfig and apply the configuration to the Devtron service. Here are the steps to do this:
1. Create a BackendConfig yaml file with the increased timeoutSec value. For example:
- apiVersion: cloud.google.com/v1beta1
- kind: BackendConfig
- metadata:
- name: devtron-backendconfig
- spec:
- timeoutSec: 1800
you can adjust the timeoutSec value in the backendConfig as per your specific requirement. This value determines the maximum amount of time the load balancer should wait for a response from the backend before timing out. You can set the timeoutSec value to a higher or lower value based on your use case and the response time of your backend.
2. Apply the BackendConfig to the GKE cluster using the following command:
- kubectl apply -f <path-to-backendconfig.yaml> -n devtroncd
3. Add the cloud.google.com/backend-config: '{"default": "devtron-backendconfig"}' annotation to the Devtron service with the BackendConfig name. For example:
- apiVersion: v1
- kind: Service
- metadata:
- name: devtron-service
- namespace: devtroncd
- annotations:
- cloud.google.com/backend-config: '{"default": "devtron-backendconfig"}'
4. Save the changes to the Devtron service configuration.
With these configuration changes, the Devtron dashboard connection should no longer timeout after 30 seconds, allowing for a more stable and consistent connection.
