kubernetes环境下harbor安装.md

wls1036 docker, kubernetes 2021-05-03

介绍

harbor支持docker compose和helm两种方式进行安装，一般情况下如果是kubernetes运行环境推荐用helm进行安装，如果是纯docker环境建议用docker compose进行安装，本次安装使用helm进行安装，安装版本为v2.2.1

创建命名空间

harbor包含服务较多，建议单独创建命名空间进行安装，便于后续的管理

apiVersion: v1
kind: Namespace
metadata:
  name: harbor
  labels:
    name: harbor

另存为harbor-namespace.yaml文件，并执行kubectl apply -f harbor-namespace.yaml命令进行创建

创建共享目录

目录必须创建在共享存储的介质上面，比如NFS等

mkdir -p /u02/appdata/harbor/registry
mkdir -p /u02/appdata/harbor/chartmuseum
mkdir -p /u02/appdata/harbor/jobservice
mkdir -p /u02/appdata/harbor/database
mkdir -p /u02/appdata/harbor/redis
mkdir -p /u02/appdata/harbor/trivy
chmod 777 /u02/appdata/harbor/registry
chmod 777 /u02/appdata/harbor/chartmuseum
chmod 777 /u02/appdata/harbor/jobservice
chmod 777 /u02/appdata/harbor/database
chmod 777 /u02/appdata/harbor/redis
chmod 777 /u02/appdata/harbor/trivy

创建PV PVC

PV根据实际情况进行创建，这里直接创建本地目录PV，通过PVC进行绑定关联

helm安装

  • 下载helm

从helm的gitlab仓库根据平台下载最新版本helm安装包，本次使用的是Helm v3.5.4

  • 将安装包上传至服务器
[root]
tar -xvf helm-v3.5.4-linux-amd64.tar.gz
cp linux-amd64/helm /usr/local/bin
$ helm version

  • 下载harbor Chart
helm repo add harbor https://helm.goharbor.io
helm fetch harbor/harbor --untar
cd harbor

  • 离线问题解决

helm需要从远程仓库下载chart配置信息，如果安装服务器无法连接外网，可以在外网先下载好配置信息再上传至服务器

  • 安装harbor
helm install harbor . --namespace harbor

初次安装时间会稍微长些，因为后台在下载镜像，如果所有的服务都running说明安装成功

$ kubectl get pods -n harbor
NAME                                           READY   STATUS    RESTARTS   AGE

harbor-harbor-trivy-0                          1/1     Running   0          18m

配置访问地址

harbor通过Ingress进行访问，Ingerss访问地址就是上面配置的externalURL

$ kubectl get ing -n harbor
NAME                           HOSTS                   ADDRESS                  
harbor-harbor-ingress          harbor.xxx.com   10.116.2.108,10.116.2.111
harbor-harbor-ingress-notary   notary.xxx.com   10.116.2.108,10.116.2.111

如果是本地测试，需要将地址加入本地hosts文件，通过浏览器即可访问，如果是正式系统需要加入企业内部dns域名系统中进行解析
