前言

Harbor是一个可以在Kubernetes上运行的容器存储库。我认为对于那些希望在私有云中拥有自己的容器存储库的人来说，这将是一种选择。功能包括多租户，映像复制和容器映像漏洞检查。

本部署文档的PV未使用共享存储，仅使用HostPath，作为生产应该使用共享存储。

环境

• Kubernetes v1.14.6-aliyun.1
• Helm v2.12.3

为保证应用调度到指定节点，为node新增一个标签

kubectl label nodes xx_node app.kubernetes.io/name=harbor
kubectl get node -l "app.kubernetes.io/name=harbor"

部署步骤

部署 Harbor 的前置条件步骤如下

• Ingress Controller
• 创建namespace
• 创建 Harbor PV(PersistentVolume)

Ingress Controller

如果阿里云 SaaS，可以忽略。

这里我们使用 nginx作为集群的负载，实际你也可以使用其它，比如 HAProxy、Traefik等

$ helm install stable/nginx-ingress --name my-nginx --set rbac.create=true --name nginx-ingress

查看部署的版本

POD_NAME=$(kubectl get pods -l app.kubernetes.io/name=ingress-nginx -o jsonpath='{.items[0].metadata.name}')
kubectl exec -it $POD_NAME -- /nginx-ingress-controller --version

https://kubernetes.github.io/ingress-nginx/deploy/

创建 Namespace

为harbor 创建一个名为 harbor-system命名空间

kubectl create ns harbor-system

创建 PersistentVolume（PV）以存储应用数据

在xx_node主机中创建目录

[root@kube-node-03 harbor]# ls
for dir in chartmuseum  database  jobservice  redis  redistry
do
    mkdir -pv /data/harbor/$dir;
done

创建pv文件

资源创建

kubectl -n harbor-system allply -f .

查看创建的PV资源

部署harbor

$ git clone https://github.com/goharbor/harbor-helm.git
$ cd harbor-helm

为harbor配置pv，实现单机持久性存储

helm install --wait --name harbor --namespace harbor-system . \
  --set expose.ingress.hosts.core=harbor.haid.com.cn \
  --set expose.ingress.hosts.notary=notary.haid.com.cn \
  --set expose.tls.secretName=ingress-cert-with-haid.com.cn \
  --set persistence.enabled=enable \
  --set externalURL=https://harbor.haid.com.cn \
