TL;DL

LonghornがインストールされているK8sクラスタ内のノードに入って

sudo apt install nfs-common

を実行

Longhornのinstall

kubectl apply -f https://raw.githubusercontent.com/longhorn/longhorn/v1.3.0/deploy/longhorn.yaml

LonghornUIにアクセスできるようにingressの設定

USER=<USERNAME_HERE>; PASSWORD=<PASSWORD_HERE>; echo "${USER}:$(openssl passwd -stdin -apr1 <<< ${PASSWORD})" >> auth

kubectl -n longhorn-system create secret generic basic-auth --from-file=auth

longhorn-ingress.ymlを作成

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: longhorn-ingress
  namespace: longhorn-system
  annotations:
    # type of authentication
    nginx.ingress.kubernetes.io/auth-type: basic
    # prevent the controller from redirecting (308) to HTTPS
    nginx.ingress.kubernetes.io/ssl-redirect: 'false'
    # name of the secret that contains the user/password definitions
    nginx.ingress.kubernetes.io/auth-secret: basic-auth
    # message to display with an appropriate context why the authentication is required
    nginx.ingress.kubernetes.io/auth-realm: 'Authentication Required '
    # custom max body size for file uploading like backing image uploading
    nginx.ingress.kubernetes.io/proxy-body-size: 10000m
spec:
  rules:
  - http:
      paths:
      - pathType: Prefix
        path: "/"
        backend:
          service:
            name: longhorn-frontend
            port:
              number: 80

kubectl -n longhorn-system apply -f longhorn-ingress.yml

K8sクラスタ内のノードにアクセスしてnfs-commonをinstall

sudo apt install nfs-common

PVC作成例

Longhornがinstallされている場合はPVCを作成すればPVCで要求したPVを自動作成してくれるのでPVCのみを記述すればOK

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pv-test
  labels:
    <PVと接続したいPodのラベル>
spec:
  storageClassName: longhorn
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 5Gi
