Go worker 应用程序未在 Cloud Foundry 中启动

Question

我正在尝试在 Cloud Foundry 中运行一个 go worker 应用程序(不绑定(bind)到路由)。我可以在本地启动 Go 二进制文件，它运行良好。

当应用程序尝试在 Cloud Foundry 中启动时，出现以下错误。

下面是我的Procfile。

worker: ./slack-disable-2fa

下面是我的 manifest.yml 文件。

applications:
- path: .
  memory: 512MB
  instances: 1
  domain: mybluemix.net
  name: myapp
  host: myapp
  no-route: true
  disk_quota: 1024M
  command: ./slack-disable-2fa
  buildpack: https://github.com/cloudfoundry/go-buildpack.git

来自 go 应用程序的片段 (slack-disable-2fa.go)

package main

import (
    "fmt"
    "time"
)


func main() {

    for {
        fmt.Printf("hello\n")
        fmt.Printf("Running again in 24 hours...\n")
        time.Sleep(time.Hour * 1)
    }

}

Answer 1

从 Procfile 中删除“./”前缀。

它应该只包含命令名称。

worker: slack-disable-2fa

同时从 manifest.yml 中删除“./”前缀。

  command: slack-disable-2fa
