openshift - Openshift new-app 不适用于 dockerfile

问题描述

我正在尝试使用 CLI 在 Openshift 中部署新应用程序。当我使用 GUI 并单击“从 docker 文件构建”时，一切正常。但是当我使用 CLI 时，它不会。

这些是我的仓库中的文件：

Dockerfile

FROM golang:1.11-alpine
RUN mkdir /app
COPY main.go /app
WORKDIR /app
RUN go build -o main .
EXPOSE 8080 8888
USER 1001
ENTRYPOINT ["/app/main"]

main.go

package main

import (
    "fmt"
    "net/http"
)

func helloHandler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintln(w, "<h1>Hello OpenShift! Updated build</h1>")
}

func listenAndServe(port string) {
    fmt.Printf("serving on %s\n", port)
    err := http.ListenAndServe(":"+port, nil)
    if err != nil {
        panic("ListenAndServe: " + err.Error())
    }
}

func main() {
    http.HandleFunc("/", helloHandler)
    go listenAndServe("8080")
    select {}
}

我正在关注这篇文章。我已将文件复制到我的私人仓库并使用源密码进行克隆。就像那里提到的那样，我使用了这个命令和 source-secret

oc new-app https://git.abcd.corp.mycompany.com/12345/openshift-trail.git#development --source-secret=my-secret --name=demo-blah

这给了我以下错误

error: unable to load template file "https://git.abcd.corp.mycompany.com/12345/openshift-trail.git#development": error parsing https://git.abcd.corp.mycompany.com/12345/openshift-trail.git#development: error converting YAML to JSON: yaml: line 3: mapping values are not allowed in this context
error: git ls-remote failed with: fatal: unable to access 'https://git.abcd.corp.mycompany.com/12345/openshift-trail.git/': Problem with the SSL CA cert (path? access rights?);  local file access failed with: stat https://git.abcd.corp.mycompany.com/12345/openshift-trail.git#development: no such file or directory
error: unable to locate any images in image streams, templates loaded in accessible projects, template files, local docker images with name "https://git.abcd.corp.mycompany.com/12345/openshift-trail.git#development"

Argument 'https://git.abcd.corp.mycompany.com/12345/openshift-trail.git#development' was classified as an image, image~source, or loaded template reference.

The 'oc new-app' command will match arguments to the following types:

  1. Images tagged into image streams in the current project or the 'openshift' project
     - if you don't specify a tag, we'll add ':latest'
  2. Images in the Docker Hub, on remote registries, or on the local Docker engine
  3. Templates in the current project or the 'openshift' project
  4. Git repository URLs or local paths that point to Git repositories

--allow-missing-images can be used to point to an image that does not exist yet.

根据openshift doco，它说如果 repo 中有 Dockerfile，它应该自动检测它。但是在这里我遇到了一个我无法理解的奇怪错误。任何帮助深表感谢。

解决方案

You could just build it as a regular dockerfile on your own computer and upload it to a Docker registry and then deploy it to openshift from the remote registry or you could even push it to the built in registry on openshift.

I think the command you are looking for is probably 


    oc new-build
