Node Verifications

View Helm Chart Values

  • Utilize this step to ensure the installed Helm Chart user supplied variables are correct
  • The values were defined when we executed the helm install command with specified parameters
helm -n akash-services get values akash-node

Expected/Sample Output

  • If custom values were included with the helm install command the following output is expected (example)
helm -n akash-services get values akash-node

USER-SUPPLIED VALUES:
state_sync:
  enabled: true
  • If no custom values were included with the helm install command the following output is expected
USER-SUPPLIED VALUES:
null

Verify Akash Node Pod Status

  • Confirm that the Akash Node pod is in a pristine state
kubectl get pods -n akash-services

Expected/Sample Output

kubectl get pods -n akash-services

NAME                            READY   STATUS    RESTARTS   AGE
akash-node-1-78954d745c-xgkhx   1/1     Running   0          50s

Verify Akash Node Sync via Logs

  • Ensure that the Akash Node pod has errors of concerns in logs and that the blockchain sync is progressing
  • Replace the name-of-pod variable with akash-node pod name displayed in the previous step
kubectl logs <name-of-pod> -n akash-services | grep -iv peer | tail

Expected/Sample Output

kubectl logs akash-node-1-78954d745c-xgkhx -n akash-services | grep -iv peer | tail

Akash Node Status

Access Pod Shell

  • Access the Kubernetes shell of the Akash Node deployment to view sync status
kubectl exec --stdin --tty -n akash-services <pod-name> -- /bin/bash

Verify Node Status

akash status

Expected/Sample Output

  • Note the following expected values:
    • catching_up - should be false once your Node is in sync with the blockchain
    • latest_block_height - compare this block height with the latest height on a block explorer as another method of validating if the node is in sync or if not in sync how close to completing that process the node may be
kubectl exec --stdin --tty -n akash-services akash-node-1-78954d745c-g46pf -- /bin/bash

Additional Node Verification

STEP 1 - From the K8s Control-Plane Node

export AKASH_NODE="http://$(kubectl -n akash-services get ep akash-node-1 -o jsonpath='{.subsets[0].addresses[0].ip}'):26657"

curl -s "$AKASH_NODE/status" | jq -r .

STEP 2 - From a Remote Address (Outside the K8s Network)

  • Use kubectl port-forward for forwarding the akash node (RPC) port 26657/tcp to your local station.

Forward 26657 to 127.0.0.1:26657

kubectl -n akash-services port-forward service/akash-node-1 26657:26657

Expected/Example Output

$ kubectl -n akash-services port-forward service/akash-node-1 26657:26657
Forwarding from 127.0.0.1:26657 -> 26657
Forwarding from [::1]:26657 -> 26657

Put the kubectl port-forward Process into Background

  • Press Ctrl+Z and type bg + Enter as follows:
^Z
[1]+  Stopped                 kubectl -n akash-services port-forward service/akash-node-1 26657:26657
$ bg
[1]+ kubectl -n akash-services port-forward service/akash-node-1 26657:26657 &

Access the RPC as if it were Running Locally

curl -s http://127.0.0.1:26657/status | jq -r .

Stop kubectl port-forward When Done Testing

$ jobs
