前言：此文档是用来在线下环境harbor利用MinIO做镜像存储的，至于那些说OSS不香吗？或者单机harbor的，不用看了。此文档对你没啥用，如果是采用单机的harbor连接集群MinIO，请看我的另一篇博文。
环境:
应用版本：
helm v3.2.3
kubernetes 1.14.3
nginx-ingress 1.39.1
harbor 2.0
nginx 1.15.3
MinIO RELEASE.2020-05-08T02-40-49Z
### 这里就不讲解kubernetes集群怎么搭建了。我们kubernetes共享存储为了简单，采用的是nfs。我们先讲解一下怎么采用nfs做k8s持久存储。
### 注意执行主机，除了nfs-server是在94那台服务器执行了相关命令，其他的大部分是在master1上面执行
## 一、nfs-client-provisioner
### 1、在nfs-server安装nfs服务
yum -y install nfs-utils rpcbind mkdir /nfs/data chmod 777 /nfs/data echo ‘/nfs/data *(rw,no_root_squash,sync)‘ > /etc/exports exportfs -r systemctl restart rpcbind && systemctl enable rpcbind systemctl restart nfs && systemctl enable nfs rpcinfo -p localhost showmount -e 10.0.0.94
### 2、在其他服务器安装nfs-client
yum install -y nfs-utils
### 3、在k8s-master1上安装nfs-client-provisioner 实现动态持久存储，nfs-client-provisioner 是一个Kubernetes的简易NFS的外部provisioner，本身不提供NFS
cd /usr/local/src && mkdir nfs-client-provisioner && cd nfs-client-provisioner
### 注意deployment.yaml文件中，IP对应的是nfs-server的，PATH路径对应的是nfs-server的/etc/exports的路径
cat > deployment.yaml << EOF

EOF
cat > rbac.yaml << EOF kind: ClusterRole apiVersion: rbac.authorization.k8s.io/v1 metadata: name: nfs-client-provisioner-runner rules: - apiGroups: [""] resources: ["persistentvolumes"] verbs: ["get", "list", "watch", "create", "delete"] - apiGroups: [""] resources: ["persistentvolumeclaims"] verbs: ["get", "list", "watch", "update"] - apiGroups: [""] resources: ["endpoints"] verbs: ["get", "list", "watch", "create", "update", "patch"] - apiGroups: ["storage.k8s.io"] resources: ["storageclasses"] verbs: ["get", "list", "watch"] - apiGroups: [""] resources: ["events"] verbs: ["create", "update", "patch"] --- kind: ClusterRoleBinding apiVersion: rbac.authorization.k8s.io/v1 metadata: name: run-nfs-client-provisioner subjects: - kind: ServiceAccount name: nfs-client-provisioner namespace: default - kind: ServiceAccount name: nfs-client-provisioner namespace: kube-system roleRef: kind: ClusterRole name: nfs-client-provisioner-runner apiGroup: rbac.authorization.k8s.io --- kind: Role apiVersion: rbac.authorization.k8s.io/v1 metadata: name: leader-locking-nfs-client-provisioner rules: - apiGroups: [""] resources: ["endpoints"] verbs: ["get", "list", "watch", "create", "update", "patch"] --- kind: RoleBinding apiVersion: rbac.authorization.k8s.io/v1 metadata: name: leader-locking-nfs-client-provisioner subjects: - kind: ServiceAccount name: nfs-client-provisioner # replace with namespace where provisioner is deployed namespace: default roleRef: kind: Role name: leader-locking-nfs-client-provisioner apiGroup: rbac.authorization.k8s.io EOF
cat > StorageClass.yaml << EOF apiVersion: storage.k8s.io/v1 kind: StorageClass metadata: name: managed-nfs-storage provisioner: fuseim.pri/ifs parameters: archiveOnDelete: "false" EOF
kubectl apply -f deployment.yaml kubectl apply -f rbac.yaml kubectl apply -f StorageClass.yaml
### 稍等片刻，检查nfs-client-provisioner是否正常，出现下面的输出说明正常，如果不正常请检查上面的步骤，是否存在问题
kubectl get pods -n kube-system | grep nfs nfs-client-provisioner-7778496f89-kthnj 1/1 Running 0 169m
## 二、安装helm3
cd /usr/local/src &&wget https://get.helm.sh/helm-v3.2.3-linux-amd64.tar.gz &&\ tar xf helm-v3.2.3-linux-amd64.tar.gz &&cp linux-amd64/helm /usr/bin/ &&helm version
## 三、安装nginx-controller-manager
helm repo add stable http://mirror.azure.cn/kubernetes/charts helm pull stable/nginx-ingress &&docker pull fungitive/defaultbackend-amd64 &&docker tag fungitive/defaultbackend-amd64 k8s.gcr.io/defaultbackend-amd64:1.5 &&helm template guoys nginx-ingress-*.tgz | kubectl apply -f -
## 四、安装MinIO
### 1、在准备的4台服务器安装minio Server，官方建议是准备最低4台服务器，并且是单独的磁盘空间存放minio数据
cd /usr/local/src &&wget https://dl.min.io/server/minio/release/linux-amd64/minio &&\ chmod +x minio && cp minio /usr/bin
cat > /etc/systemd/system/minio.service <<EOF [Unit] Description=Minio Documentation=https://docs.minio.io Wants=network-online.target After=network-online.target AssertFileIsExecutable=/usr/bin/minio [Service] EnvironmentFile=-/etc/minio/minio.conf ExecStart=/usr/bin/minio server $ENDPOINTS # Let systemd restart this service always Restart=always # Specifies the maximum file descriptor number that can be opened by this process LimitNOFILE=65536 # Disable timeout logic and wait until process is stopped TimeoutStopSec=infinity SendSIGKILL=no [Install] WantedBy=multi-user.target EOF
### 此处IP地址要与自己的机器地址对应或者采用域名，后缀是minio存储路径
mkdir -p /etc/minio cat > /etc/minio/minio.conf <<EOF MINIO_ACCESS_KEY=guoxy MINIO_SECRET_KEY=guoxy321export ENDPOINTS="http://10.0.0.91/minio http://10.0.0.92/minio http://10.0.0.93/minio http://10.0.0.94/minio" EOF systemctl daemon-reload && systemctl start minio && systemctl enable minio
### 2、在k8s-master1安装mc命令，并创建bucket harbor
cd /usr/local/src && wget https://dl.min.io/client/mc/release/linux-amd64/mc && \ chmod +x mc && cp mc /usr/bin/ && mc config host add minio "http://10.0.0.91:9000 http://10.0.0.92:9000 http://10.0.0.93:9000/ http://10.0.0.94:9000" guoxy guoxy321export && mc mb minio/harbor
## 五、在k8s中安装harbor
### 1、先在k8s中创建harbor要使用的TLS证书的secret，证书如果没有可以let‘s encrypt申请
kubectl create secret tls guofire.xyz --key privkey.pem --cert fullchain.pem
### 2、克隆harbor-helm
cd /usr/local/src && git clone -b 1.4.0 https://github.com/goharbor/harbor-helm
### 3、修改harbor-helm/values.yaml，由于内容太多了，我只把需要修改的内容贴出来
vim harbor-helm/values.yaml
### secretName对应刚刚创建的secret名称，core为harbor访问域名
secretName: "guofire.xyz" core: harbor.guofire.xyz notary: notary.guofire.xyz
externalURL: https://harbor.guofire.xyz
### 下面是nfs持久化存储
persistentVolumeClaim: registry: storageClass: "managed-nfs-storage" subPath: "registry" storageClass: "managed-nfs-storage" subPath: "chartmuseum" storageClass: "managed-nfs-storage" subPath: "jobservice" storageClass: "managed-nfs-storage" subPath: "database" storageClass: "managed-nfs-storage" subPath: "redis" storageClass: "managed-nfs-storage" subPath: "trivy"
### 这往下最重要，regionendpoint地址可以写nginx代理的地址和端口，我这里只写了minio Server其中一台
imageChartStorage: disableredirect: true type: s3 filesystem: rootdirectory: /storage #maxthreads: 100 s3: region: us-west-1 bucket: harbor accesskey: guoys! secretkey: guoys321export regionendpoint: http://10.0.0.92:9000 encrypt: false secure: false v4auth: true chunksize: "5242880" rootdirectory: / redirect: disabled: false maintenance: uploadpurging: enabled: false delete: enabled: true
### 4、通过helm在k8s中安装harbor
helm install harbor harbor-helm/
### 5、最后稍等3、5分钟，查看harbor应用是否正常
kubectl get pods
### 出现下面类似的输出，基本上说明harbor已经正常启动
NAME READY UP-TO-DATE AVAILABLE AGE harbor-harbor-chartmuseum 1/1 1 1 13h harbor-harbor-clair 1/1 1 1 13h harbor-harbor-core 1/1 1 1 13h harbor-harbor-jobservice 1/1 1 1 13h harbor-harbor-notary-server 1/1 1 1 13h harbor-harbor-notary-signer 1/1 1 1 13h harbor-harbor-portal 1/1 1 1 13h harbor-harbor-registry 1/1 1 1 13h zy-nginx-ingress-controller 1/1 1 1 32h zy-nginx-ingress-default-backend 1/1 1 1 32h
## 六、安装nginx 4层转发，否则无法通过nginx-ingress访问harbor
### 1、由于nginx-ingress默认是LoadBalancer模式，在线下环境无法正常使用。我们需要改为NodePort
kubectl edit svc guoys-nginx-ingress-controller
### 修改.spec.type的值为NodePort，并保存
### 2、查看nginx-ingress-controller的nodeport端口，记住80和443对应的端口
kubectl get svc | grep ‘ingress-controller‘ guoys-nginx-ingress-controller NodePort 10.200.248.214 <none> 80:32492/TCP,443:30071/TCP 32h
### 3、安装nginx4层代理
yum install -y gcc make mkdir /apps cd /usr/local/src/ wget http://nginx.org/download/nginx-1.15.3.tar.gz tar xf nginx-1.15.3.tar.gz cd nginx-1.15.3 ./configure --with-stream --without-http --prefix=/apps/nginx --without-http_uwsgi_module --without-http_scgi_module --without-http_fastcgi_module make && make install
### 下面upstream中的端口一定要跟上面2步骤NodePort的相对应
cat > /apps/nginx/conf/nginx.conf <<EOF worker_processes 1; events { worker_connections 1024; } stream { log_format tcp ‘$remote_addr [$time_local] ‘ ‘$protocol $status $bytes_sent $bytes_received ‘ ‘$session_time "$upstream_addr" ‘ ‘"$upstream_bytes_sent" "$upstream_bytes_received" "$upstream_connect_time"‘; upstream https_default_backend { server 10.0.0.91:30071; server 10.0.0.92:30071; server 10.0.0.93:30071; } upstream http_backend { server 10.0.0.91:32492; server 10.0.0.92:32492; server 10.0.0.93:32492; } server { listen 443; proxy_pass https_default_backend; access_log logs/access.log tcp; error_log logs/error.log; } server { listen 80; proxy_pass http_backend; } } EOF
### 测试并启动nginx
/apps/nginx/sbin/nginx -t /apps/nginx/sbin/nginx echo ‘/apps/nginx/sbin/nginx‘ >> /etc/rc.local
