QUESTION
I have a GKE cluster with 4 nodes in an instance group. I deployed Ingress and several pods (1 replica only of each pod so they are only on 1 node). I notice on the Google Console (Ingress details page) that all backend services remain Unhealhy although the healthchecks on the running pods are OK and my application is running. To my understanding it says it is unhealthy because out of the 4 nodes, only 1 node is running an instance of a given pod (on the Back-end service details it says "1 of 4 instances healthy"). Am I correct and should I worry and try to fix this? It's bit strange to accept an Unhealthy status when the application is running...
Edit: After further investigation, down to 2 nodes, and activating the healthcheck logs, I can see that the backend service status seems to be the status of the last executed healthcheck. So if it checks last the node that hosts the pod, it is healthy, else it is unhealthy.
GKE version: 1.16.13-gke.1
My ingress definition:

Answered 2020-Aug-05 at 19:41Please check your yaml file for your service. If it shows externalTrafficPolicy: local, then it is expected behavior.
Local means traffic will always go to a pod on the same node, while everything else is dropped. So if your deployment has only 1 replica it is serving, you will only have one healthy instance.
You can easily test that theory, scale up to 2 replicas and observe behavior. I forsee 1 healthy instance if 2nd replica lands on the same node as first replica and 2/4 healthy if 2nd replica lands on a different node. Let me know.
QUESTION
I am learning how to use an ingress to expose my application on Google Kubernetes Engine. I followed several tutorials and had a rough setup of what is needed. However, I have no clue why are my service is marked as unhealthy despite them being accessible from the NodePort service I defined directly.
Here is my deployment file: (I removed some data but the most of it remains the same)
...ANSWER
Answered 2020-Mar-09 at 04:13By tinkering with the Readiness and Liveliness probe by adding a successThreshold and FailureThreshold, I managed to get my ingress working. It might be because my application needs a little more buffer time to run.
QUESTION
Using Kubernetes 1.12.6-gke.7 or higher it is possible to create a ManagedCertificate which is then referenced from an Ingress Resource exposing a Service to the Internet.
Running kubectl describe managedcertificate certificate-name first indicates the certificate is in a Provisioning state but eventually goes to FailedNotVisible.
Despite using a Static IP and DNS that resolves fine to the http version of said service all ManagedCertificate's end up in a "Status: FailedNotVisible" state.
Outline of what I am doing:
Generating a reserved (static) external IP Address
Configuring DNS A record in CloudDNS to subdomain.domain.com to generated IP address from step 1.
- Creating a ManagedCertificate named "subdomain-domain-certificate" with kubectl apply -f with spec:domains containing a single domain corresponding to subdomain.domain.com DNS record in step 2.
- Creating a simple deployment and service exposing it
- Creating Ingress resource referring to default backend of service in step 4 as well as annotations for static ip created in step 1 and managed certificate generated in step 3.
- Confirm that Ingress is created and is assigned static IP
- Visiting http://subdomain.domain.com serves the output from pod created in deployment in step 4
After a little while
kubectl describe managedcertificate subdomain-domain-certificate
results in "Status: FailedNotVisible".

I'm simply following the tutorial here: https://cloud.google.com/kubernetes-engine/docs/how-to/managed-certs#creating_an_ingress_with_a_managed_certificate
Everything works fine until I deploy my certificate and wait 20 minutes for it to show up as:

Answered 2020-Jan-21 at 16:29I was successful in using Managedcertificate
with GKE Ingress
resource.
Let me elaborate on that:
Steps to reproduce:
- Create IP address with
gcloud
- Update the DNS entry
- Create a deployment
- Create a service
- Create a certificate
- Create a Ingress resource
Invoke below command to create static ip address:
$ gcloud compute addresses create example-address --global
Check newly created IP address with below command:
$ gcloud compute addresses describe example-address --global
Go to GCP
-> Network Services
-> Cloud DNS
.
Edit your zone with A record
with the same address that was created above.
Wait for it to apply.
Check with $ nslookup DOMAIN.NAME
if the entry is pointing to the appropriate address.
Below is example deployment which will respond to traffic:
QUESTION
I'm trying to spin up a Kubernetes cluster that I can access securely and can't seem to get that last part. I am following this tutorial: https://cloud.google.com/kubernetes-engine/docs/how-to/managed-certs
Here are the .yaml
files i'm using for my Ingress, Nodeport and ManagedCertificate
ANSWER
Answered 2019-Jul-02 at 03:46I figured out a solution to this problem. I ended up going into my GCP console, locating the load balancer associated with the Ingress, and then I noticed that there was only one frontend protocol, and it was HTTP serving over port 80. So I manually added another frontend protocol for HTTPS, selected the managed certificate from the list, and waited about 5 minutes and everything worked.
I have no idea why my ingress.yaml
didn't do that automatically though. So though the problem is fixed if there is anyone out there who knows what I would love to know.
