Demand: pod need to debug deployment of whether to provide a normal visit, but not to be exposed to the outside pod cluster.
Achieved: by mapping mechanism Kubernetes Port Forward local port to the port to achieve pod
1, the installation kubectl
Official website download page: https://kubernetes.io/docs/tasks/tools/install-kubectl/
Just download the same version Kubernetes of kubectl:
https://storage.googleapis.com/kubernetes-release/release/v1.14.1/bin/windows/amd64/kubectl.exe
Kubectl.exe the downloaded files are stored in C: \ k8s \ bin directory and add the directory to the PATH (step omitted)
2, the configuration kubectl
Need to get the configuration file:
1) Kubernetes general deployment, will generate $ HOME / .kube / config, the config files in that directory, stored in the corresponding Windows local home directory C: \ Users \ admin \ .kube under
2) If the rancher deployment, configuration files can be viewed in a cluster home, copy down also stored in the home directory of the account
3) Then cmd view cluster
kubectl get node
Instructions for configuring kubectl success.
3, create a test pod
Create a nginx, designated port 80
cat > my-nginx.yaml <<EOF
apiVersion: apps/v1
kind: Deployment
metadata:
name: my-nginx
spec:
replicas: 1
selector:
matchLabels:
k8s-app: my-nginx
template:
metadata:
labels:
k8s-app: my-nginx
spec:
containers:
- name: my-nginx
image: nginx:1.9
ports:
- containerPort: 80
EOF
# Create a pod
kubectl create -f my-nginx.yaml
# View pod name information
kubectl get svc,pod -o wide
4, set up port forwarding
1) 3080 forwards the local port to the port 80 of the container
kubectl port-forward my-nginx-6d7ddd766f-4fxxc 3080:80
Forwarding from 127.0.0.1:3080 -> 80 Forwarding from [::1]:3080 -> 80
As output, indicating successfully forward. If it is deployed on other namespace, specify the namespace with -n.
2) local browser access
127.0.0.1:3080
