kubernetes(30)：k8s包管理工具-helm(4)-harbor管理helm-charts

harbor管理 helm-charts

当我们定义完chart后需要有个地方存储，就像docker的imag，存储到registry。Harbor作为一个企业级的docker仓库，也能存储chart

 

harbor安装

docker(22)：dockers企业级私有仓库harbor

 

harbor 安装的时候 默认没有helm charts的仓库

docker-compose stop
./install.sh  --with-chartmuseum

 

安装完成之后登录页面上就会有了 helm charts 了，页面上也可以直接上传charts

在Harbor在创建一个charts项目，用于存储charts如下：

 

 

 

 

安装helm-push

helm plugin install https://github.com/chartmuseum/helm-push

在Helm Charts标签页下，可以上传我们的chart，注意它需要是使用tar压缩的压缩文件，我试过rar是不可以的。

添加到仓库列表
使用如下命令将我们的harbor仓库chart添加到helm repo:

helm repo add  myrepo https://xx.xx.xx.xx/chartrepo/charts

现在就可以安装了。

 

[root@k8s-master harbor]# helm repo add myrepo http://10.6.76.25/chartrepo/chart --username admin --password 123456  #harbor用户密码
"myrepo" has been added to your repositories
[root@k8s-master harbor]# helm repo list

[root@k8s-master harbor]#

 

上传

[root@k8s-master ~]# cd helm/
[root@k8s-master helm]# ls
