I am attempting to work through the following tutorial https://kubernetes.io/docs/tasks/job/fine-parallel-processing-work-queue/ . My problem happens at the very first step, trying to start up redis. When I run
kubectl run -i --tty temp --image redis --command "/bin/sh"I create a new pod, however running
redis-cli -h redis returns an error: Could not connect to Redis at redis:6379: Name or service not known
It looks like you don't have Kube DNS setup correctly and what you got it's just a simple problem with name resolution.
If you look again at the tutorial, they even mention you can encounter such problem:
Note: if you do not have Kube DNS setup correctly, you may need to change the first step of the above block to redis-cli -h $REDIS_SERVICE_HOST.
So just instead of using redis-cli -h redis use redis-cli -h $REDIS_SERVICE_HOST and everything should work.
