前言

记录一下根据minio官网的范本部署一个单节点单磁盘的minio服务端。

一、基础环境准备

准备一个k8s集群，配置好存储类

二、准备yaml文件

准备yaml文件，文件内定义了namespace、pvc、service、pod
minio-deployment.yaml

# https://min.io/docs/minio/kubernetes/upstream/index.html
# Deploys a new Namespace for the MinIO Pod
apiVersion: v1
kind: Namespace
metadata:
  name: minio-dev # Change this value if you want a different namespace name
  labels:
    name: minio-dev # Change this value to match metadata.name
---
# Deploy pvc for minio
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: minio-data-one-pv-claim
  namespace: minio-dev
spec:
# 我这里使用的存储类型是cephrbd
  storageClassName: rook-ceph-block
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10G

---
# Deploy service for minio
apiVersion: v1
kind: Service
metadata:
  name: minio
  namespace: minio-dev
spec:
  type: NodePort
  ports:
  - name: 9090-tcp
    protocol: TCP
    port: 9090
    targetPort: 9090
    nodePort: 32307
  - name: 9000-tcp
    protocol: TCP
    port: 9000
    targetPort: 9000
    nodePort: 32308
  selector:
    app: minio
---
# Deploys a new MinIO Pod into the metadata.namespace Kubernetes namespace
#
# The `spec.containers[0].args` contains the command run on the pod
# The `/data` directory corresponds to the `spec.containers[0].volumeMounts[0].mountPath`
# That mount path corresponds to a Kubernetes HostPath which binds `/data` to a local drive or volume on the worker node where the pod runs
# 
apiVersion: v1
kind: Pod
metadata:
  labels:
    app: minio
  name: minio
  namespace: minio-dev
spec:
  containers:
  - name: minio
    image: 192.168.150.35:10002/library/minio:RELEASE.2022-12-07T00-56-37Z
    env:
    - name: MINIO_ACCESS_KEY
      value: "admin"
    - name: MINIO_SECRET_KEY
      value: "admin123456"
    command:
    - /bin/bash
    - -c
    args: 
    - minio server /data --console-address :9090  --address :9000
    # add port for pod
    ports:
    - containerPort: 9090
      name: console-address
    - containerPort: 9000
      name: address
    volumeMounts:
    - name: minio-data-one 
      mountPath: /data  
#nodeSelector:
  #  kubernetes.io/hostname: kubealpha.local
  volumes:
  - name: minio-data-one
    persistentVolumeClaim:
      claimName: minio-data-one-pv-claim

三、执行部署

kubectl apply -f minio-deployment.yaml
#输出
namespace/minio-dev created
persistentvolumeclaim/minio-data-one-pv-claim created
service/minio created
pod/minio created

四、命令行查看部署结果

kubectl get pod -o wide -n minio-dev
kubectl get svc -o wide -n minio-dev
kubectl get pvc -o wide -n minio-dev

输出

[root@kubeadmin minio]# kubectl get pod -o wide -n minio-dev
