[쿠버네티스] Dashboard 설정

1. 현재 모든 서비스를 확인한다. 

kubectl get service -A

 

 

대시보드 설정시 노드포트를 설정하는 것은  개발용도로만 사용할 수 있으며  서비스 용도로는 사용하지 않는다.

 

2. node의 정보를 확인해본다. 

kubectl get nodes -o wide

EXTERNAL-IP 할당을 받아야 한다. 

 

 

 

 

 

1. MetalLB 설치

 

1) 

# see what changes would be made, returns nonzero returncode if different
kubectl get configmap kube-proxy -n kube-system -o yaml | \
sed -e "s/strictARP: false/strictARP: true/" | \
kubectl diff -f - -n kube-system

# actually apply the changes, returns nonzero returncode on errors only
kubectl get configmap kube-proxy -n kube-system -o yaml | \
sed -e "s/strictARP: false/strictARP: true/" | \
kubectl apply -f - -n kube-system

2)

kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.13.9/config/manifests/metallb-native.yaml

3)

kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.13.9/config/manifests/metallb-frr.yaml

 

 

 

2. ingress-nginx 설치

문서:https://thekoguryo.github.io/oracle-cloudnative/oss/ingress-controller/1.install-nginx-ingress-controller/

 

1) nginx ingress controller 설치할 파일 deploy.yaml을 다운로드 

wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.6.4/deploy/static/provider/cloud/deploy.yaml

 

혹은 

kubectl applly -f [해당 링크]


kubectl applly -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.6.4/deploy/static/provider/cloud/deploy.yaml

 

 

2) 배포하기 

kubectl apply -f deploy.yaml

* 충분한 시간을 기다림

 

 

- matalb-system 확인하기

kubectl get all -A

 

 

kubeclt get all -n metallb-system

컨트롤러 두개가 생김 위에 000은 의도된것이다. 냅두면됨

 kubectl get all -n ingress-nginx 치기 3개가 나오는데 nginx컨트롤러 하나만 올ㄹ라오면 되고 external-ip 가 올라오는 걸 확인해야함

 

 

 

 

metalLB설치 하기 

 

설정:

# see what changes would be made, returns nonzero returncode if different
kubectl get configmap kube-proxy -n kube-system -o yaml | \
sed -e "s/strictARP: false/strictARP: true/" | \
kubectl diff -f - -n kube-system

# actually apply the changes, returns nonzero returncode on errors only
kubectl get configmap kube-proxy -n kube-system -o yaml | \
sed -e "s/strictARP: false/strictARP: true/" | \
kubectl apply -f - -n kube-system

 

 

MetalLB를 설치하려면 매니페스트를 적용  ( 2개 적용)

kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.13.9/config/manifests/metallb-native.yaml

kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.13.9/config/manifests/metallb-frr.yaml

 

 

설정 정보 확인하기 

 

 

 

 

metallb-pool.yaml 

 

apiVersion: metallb.io/v1beta1
kind: IPAddressPool
metadata:
  name: metallb-pool
  namespace: metallb-system
spec:
  addresses:
  - 192.168.25.200-192.168.25.250

kubectl apply -f metallb-pool.yaml

 

- dashboard   설치 하기 

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.6.1/aio/deploy/recommended.yaml

 

로드밸런서 타입으로 변경하기 

kubectl edit service kubernetes-dashboard -n kubernetes-dashboard
