Troubleshooting Commands¶
Ping redis Redis Workload¶
This command allows you to execute the redis-cli PING command on a specific deployment within a given namespace, using a specified context. It's a way to check if the Redis server is running and responding within a Kubernetes cluster.
kubectl exec deployment/redis --context=gke_runwhen-nonprod-sandbox_us-central1_sandbox-cluster-1-cluster -n voting-app -- redis-cli PING

# This command is using kubectl to execute a command inside a running container in a Kubernetes deployment.
# The command being executed inside the container is 'redis-cli PING', which checks if the Redis server is responding.
# Start the multi-line command by using kubectl exec with the appropriate flags and parameters
kubectl exec deployment/${DEPLOYMENT_NAME} \
--context=${CONTEXT} \
-n ${NAMESPACE} \
-- redis-cli PING
Verify redis Redis Read Write Operation¶
This command uses kubectl to execute a command within a specific deployment, in a specified context and namespace, and uses the redis-cli tool to set a key in Redis to 0 for health check purposes.
kubectl exec deployment/redis --context=gke_runwhen-nonprod-sandbox_us-central1_sandbox-cluster-1-cluster -n voting-app -- redis-cli SET runwhen_task_rw_healthcheck 0Learn more
