Lab 11.2. Why two services have same endpoints?
Hi!
I'm trying to make Lab 11.2. Most steps are ok except ones where different configuration for web-one
and web-two
are needed.
Here are configs:
1. web-one.yaml
:
apiVersion: apps/v1 kind: Deployment metadata: name: web-one labels: system: secondary spec: selector: matchLabels: system: secondary replicas: 1 template: metadata: labels: system: secondary spec: containers: - image: nginx:1.20.1 imagePullPolicy: Always name: nginx ports: - containerPort: 80 protocol: TCP
web-two.yaml
:
apiVersion: apps/v1 kind: Deployment metadata: name: web-two labels: system: secondary spec: selector: matchLabels: system: secondary replicas: 1 template: metadata: labels: system: secondary spec: containers: - image: nginx:1.20.1 imagePullPolicy: Always name: nginx ports: - containerPort: 80 protocol: TCP
Both created successfully and exposed:
[07:57]user@ubuntu-vbox-k8s-master[~]$ kubectl create -f web-one.yaml deployment.apps/web-one created [07:57]user@ubuntu-vbox-k8s-master[~]$ kubectl create -f web-two.yaml deployment.apps/web-two created [07:58]user@ubuntu-vbox-k8s-master[~]$ kubectl get pods NAME READY STATUS RESTARTS AGE myingress-ingress-nginx-controller-459tg 1/1 Running 0 72m myingress-ingress-nginx-controller-855vf 1/2 CrashLoopBackOff 9 (113s ago) 21m web-one-84655f9947-vcs4p 1/1 Running 0 56s web-two-84655f9947-kfsrm 1/1 Running 0 52s [07:58]user@ubuntu-vbox-k8s-master[~]$ kubectl expose deployment web-one --type=ClusterIP --port=80 service/web-one exposed [07:58]user@ubuntu-vbox-k8s-master[~]$ kubectl expose deployment web-two --type=ClusterIP --port=80 service/web-two exposed [08:00]user@ubuntu-vbox-k8s-master[~]$ kubectl get svc NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 30d myingress-ingress-nginx-controller LoadBalancer 10.101.135.134 <pending> 80:30796/TCP,443:30645/TCP 74m myingress-ingress-nginx-controller-admission ClusterIP 10.110.32.128 <none> 443/TCP 74m web-one ClusterIP 10.97.84.234 <none> 80/TCP 2m19s web-two ClusterIP 10.107.37.129 <none> 80/TCP 2m14s [08:01]user@ubuntu-vbox-k8s-master[~]$ kubectl get ep NAME ENDPOINTS AGE kubernetes 192.168.56.108:6443 30d myingress-ingress-nginx-controller 192.168.77.30:443,192.168.77.30:80 75m myingress-ingress-nginx-controller-admission 192.168.77.30:8443 75m web-one 192.168.77.35:80,192.168.77.36:80 3m24s web-two 192.168.77.35:80,192.168.77.36:80 3m19s
As you see at last command output, web-one
and web-two
are mixed. I definitely missed something.
Could anybody help?

Use different label for web-one Deployment ?

Hello,
What is the issue, in particular. The same deployment may have several services. Which is the step that is the problem? I want to be sure to help you on the correct step.
Regards,

Hi @Gim6626,
Both Deployment definition files show the same label and selector. Two operators with the same label causes resource management conflicts.
You can revisit the two Deployment definition files and correct the labels and selectors, or create both deployments via imperative commands - much easier and labels will be correctly assigned.
