QUESTION

Go service name change for linkerd

Asked 2021-Nov-16 at 17:19

I have configured linkerd with 2 clusters in GKE (west and east cluster) for multicluster purpose. I used this demo app provided by google https://github.com/GoogleCloudPlatform/microservices-demo

First I did it with Istio and everything worked out fine, but with linkerd its different. As expected the exported service from east to west cluster with get the cluster name appended to the service. eg in west cluster ,you will get currencyservice-east.

The problem I think I am having is that the frontend in the west cluster keeps sending request to currencyservice instead of currencyservice-east.

I didn't have this problem in Istio because Istio used the same service name across clusters. I am not a GO programmer, but I have googled my life to find out where the service name was defined in the frontend source code to change it but I have not succeeded.

another alternative will be for linkerd to maintain the service name while exporting it.

please guys help me.

You can use a TrafficSplit on the source cluster to direct calls to currentservice to currentservice-east.

You are using IntelliJ IDEA and did not update the pom information (Icon in the uppoer right with small 'm' symbol.)

Therefore the dependencies are not resolved properly.

Besides I suggest to use a single module project for spring boot applications, if there is no real requirement to do otherwise.

ANSWER

Answered 2020-Jun-22 at 09:07

There are a few reasons why you encounter these errors:

There might be an issue with the existing cache and/or disc space. In order to fix it you need to clear the APT cache by executing: sudo apt-get clean and sudo apt-get update.
The same goes with existing docker images. Execute: docker image prune -f and docker container prune -f in order to remove unused data and free disc space.
If you don't care about the security risks, you can try to run the apt-get command with the --allow-unauthenticated or --allow-insecure-repositories flag. According to the docs:

Ignore if packages can't be authenticated and don't prompt about it. This can be useful while working with local repositories, but is a huge security risk if data authenticity isn't ensured in another way by the user itself.

Please let me know if that helped.

Online Boutique Extensions

Asked 2020-Aug-01 at 15:14

I have been working on extending the GCP Online Boutique microservices example, and I would like to add Istio AuthorizationPolicy resources to the system.

Concretely, I want an AuthorizationPolicy to block all not-whitelisted traffic to cartservice, and I want to whitelist traffic from frontend to cartservice.

Currently, I am able to block traffic with an AuthorizationPolicy, but I cannot whitelist traffic by principal or namespace.

For context, here is my system setup. (Anything not explicitly stated here is the default from the demo linked above)

ANSWER

Answered 2020-Aug-01 at 15:14

For reference, after debugging in person with OP, we discovered that the cluster was underspecified in terms of CPU usage. On resizing the cluster to have additional CPU (1 vCPU -> 4 vCPUs), we were able to get authz policies working and respected.

Our hypothesis is that istiod was failing to respond to requests because of this issue. We do not know why.

Answer

The timeout of the Readiness Probe (1 second) was too short.

More Info

The relevant Readiness Probe is defined such that /bin/grpc_health_probe -addr=:8080 is run inside the server container.

You would expect a 1 second timeout to be sufficient for such a probe but this is running on Minikube so that could be impacting the timeout of the probe.

QUESTION

How I use one YAML to deploy two servers where one depends on the other one in Kubernetes

Asked 2020-Jul-09 at 11:27

I have two applications, nginx and redis, where nginx uses redis to cache some data so the redis address must be configured in nginx.

On the one hand, I could first apply the redis deployment and get its IP and then apply the nginx deployment to set up the two application in my minikube.

But on the other, to simplify installation in the Kubernetes Dashboard for QA, I want to create a single Kubernetes YAML file (like GoogleCloudPlatform/microservices-demo/kubernetes-manifests.yaml) to deploy these two applications on two diverse Pods. However, if I do it by means of Environment Variables, I cannot get the redis address.

So how do I achieve it?

...

ANSWER

Answered 2020-Jul-08 at 11:25

Hardcoding IP-address is not a good practice. Instead you can create a service for redis as well and configure the service dns name in your nginx deployment using the kubernetes dns config like this my-svc.my-namespace.svc.cluster-domain.example. Your nginx will then communicate to the redis container through this service.
