Objective
I want to access the redis database in kubernetes, from a function inside ibm functions using javascript.
Question
How do I get the right URI, when redis is running on a Pod in Kubernetes?
Situation
I used this sample to setup the redis database in kubernetes This is the link to the sample in Kubernetes I run Kuberentes inside IBM Cloud.
Findings
I was not able to find a answer to my question on the redis documentation
As far as I understand by default no password configured. Is this assumption right?
redis://[USER]:[PASSWORD]@[CLUSTER-PUBLIC-IP]:[PORT]Thanks for help ... I know this is maybe a to simple question, but currently I do not see the tree in the woods ;-)
As far as I understand by default no password configured.
Yes, there is no default password in that image with Redis, you are right.
If you following the instruction you mentioned, you will use a kubectl proxy, which will forward port of your Redis in cluster to your local machine by call kubectl port-forward redis-master 6379:6379.
So in that case, Redis will be available on redis://localhost:6379 on your PC.
If you want to make it available directly from ouside of the cluster, you need to create Service with NodePort, Service with LoadBalancer (if you in Cloud) or simply Service with Ingress.
Inside a cluster, you can create Service with Cluster IP (which is actually simply Service, because it always has Cluster IP) for your Redis pod and will be available on:
redis://[USER]:[PASSWORD]@[SERVICE-IP]:[PORT]
Here is a good official documentation about connecting applications with service.
