标签：after fas logic and hub pci err highlight png 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： ## 一、nfs-client-provisioner ### 2、在其他服务器安装nfs-client ### 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 ### 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 ## 二、安装helm3 ## 三、安装nginx-controller-manager ## 四、安装MinIO ### 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 ### 2、在k8s-master1安装mc命令，并创建bucket 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 ### 2、克隆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 ### secretName对应刚刚创建的secret名称，core为harbor访问域名 ### 下面是nfs持久化存储 ### 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 ### 4、通过helm在k8s中安装harbor ### 5、最后稍等3、5分钟，查看harbor应用是否正常 ### 出现下面类似的输出，基本上说明harbor已经正常启动 ## 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 ### 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 ### 3、安装nginx4层代理 ### 下面upstream中的端口一定要跟上面2步骤NodePort的相对应 ### 测试并启动nginx ## 如果此文档对你有所帮助，请不吝打赏 在kubernetes中搭建harbor，并利用MinIO对象存储保存镜像文件 标签：after fas logic and hub pci err highlight png 原文地址：https://www.cnblogs.com/guoyishen/p/13113501.html
helm v3.2.3

nginx-ingress 1.39.1
harbor 2.0
nginx 1.15.3

### 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
### 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
yum install -y nfs-utils
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
cat > rbac.yaml
cat > StorageClass.yaml
kubectl apply -f deployment.yaml
kubectl apply -f rbac.yaml
kubectl apply -f StorageClass.yaml
kubectl get pods -n kube-system | grep nfs

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

### 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

## 七、最后进行测试，推送镜像到harbor。成功后查看minio的harbor bucket是否存在docker目录。如果存在说明成
