helm上传charts模板404问题

helm上传charts模板404问题

故障现象

通过helm push xxx 到harbor中的时候，报错404

#helm push aaaa-www https://harbor-ceshi.aaaa.com/api/chartrepo/helm-test --username admin --password xxxx
Error: 404: <!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
...

Error: plugin "push" exited with error

故障排查

  • 查看helm push文档
https://github.com/imroc/helm-push

# helm push -h
Helm plugin to push chart package to TencentHub

Examples:

  $ helm push mychart-0.1.0.tgz myhubrepo                     # push .tgz from "helm package"
  $ helm push . myhubrepo                                     # package and push chart directory
  $ helm push . --version="1.2.3" myhubrepo                   # override version in Chart.yaml
  $ helm push . https://hub.tencentyun.com/charts/myhubrepo   # push directly to chart repo URL

Usage:
  helm push [flags]

Flags:
  -h, --help              help for helm
  -p, --password string   Override HTTP basic auth password [$HELM_REPO_PASSWORD]
  -u, --username string   Override HTTP basic auth username [$HELM_REPO_USERNAME]
  -v, --version string    Override chart version pre-push

helm的使用很简单。
#helm repo list
#helm push 文件或者目录 仓库名称即可
  • 从上面来看，harbor里面的url请求有问题。url没有访问到。查看core的源代码，查看route源码.
https://github.com/goharbor/harbor/blob/master/src/core/router.go
可以看到chart的相关配置
    // APIs for chart repository
    if config.WithChartMuseum() {
        // Charts are controlled under projects
        chartRepositoryAPIType := &api.ChartRepositoryAPI{}
        beego.Router("/api/chartrepo/health", chartRepositoryAPIType, "get:GetHealthStatus")
        beego.Router("/api/chartrepo/:repo/charts", chartRepositoryAPIType, "get:ListCharts")
        beego.Router("/api/chartrepo/:repo/charts/:name", chartRepositoryAPIType, "get:ListChartVersions")
        beego.Router("/api/chartrepo/:repo/charts/:name", chartRepositoryAPIType, "delete:DeleteChart")
        beego.Router("/api/chartrepo/:repo/charts/:name/:version", chartRepositoryAPIType, "get:GetChartVersion")
        beego.Router("/api/chartrepo/:repo/charts/:name/:version", chartRepositoryAPIType, "delete:DeleteChartVersion")
        beego.Router("/api/chartrepo/:repo/charts", chartRepositoryAPIType, "post:UploadChartVersion")
        beego.Router("/api/chartrepo/:repo/prov", chartRepositoryAPIType, "post:UploadChartProvFile")
        beego.Router("/api/chartrepo/charts", chartRepositoryAPIType, "post:UploadChartVersion")

        // Repository services
        beego.Router("/chartrepo/:repo/index.yaml", chartRepositoryAPIType, "get:GetIndexByRepo")
        beego.Router("/chartrepo/index.yaml", chartRepositoryAPIType, "get:GetIndex")
        beego.Router("/chartrepo/:repo/charts/:filename", chartRepositoryAPIType, "get:DownloadChart")

        // Labels for chart
        chartLabelAPIType := &api.ChartLabelAPI{}
        beego.Router("/api/chartrepo/:repo/charts/:name/:version/labels", chartLabelAPIType, "get:GetLabels;post:MarkLabel")
        beego.Router("/api/chartrepo/:repo/charts/:name/:version/labels/:id([0-9]+)", chartLabelAPIType, "delete:RemoveLabel")
    }

  • 确认harbor是否开启了WithChartMuseum

    # docker ps | grep chartmuseum
260262d76c2d        goharbor/chartmuseum-photon:v0.8.1-v1.8.1           "/docker-entrypoint.…"   2 months ago        Up 2 months (healthy)   9999/tcp

  • 查看api

这里通过源码来看我们采用repo进行push上传，不能采用/chartrepo/helm-test接口来上传。查看route，发现我们上传的接口
beego.Router("/api/chartrepo/:repo/charts", chartRepositoryAPIType, "post:UploadChartVersion")
beego.Router("/api/chartrepo/charts", chartRepositoryAPIType, "post:UploadChartVersion")

这2个接口的区别
/api/chartrepo/charts: 上传默认的charts仓库library中
/api/chartrepo/:repo/charts：上传到自定义的charts仓库中

解决

修改仓库的地址

#helm push aaaa-www https://harbor-ceshi.aaaa.com/api/chartrepo/helm-test --username admin --password xxxx

# helm push aaaa-www https://harbor-ceshi.aaaa.com/api/chartrepo/helm-test/charts --username admin --password xxxx  
 Pushing aaaa-www-0.1.0.tgz to https://harbor-ceshi.aaaa.com/api/chartrepo/helm-test/charts...
Done.
