docker - 如何从Cloud Foundry上的存储库部署Docker镜像？

Question

我推 jetty 图片

cf push --docker-image rocker/rstudio --docker-username rstudio-test

以及分期过程何时开始

我发现401错误

我做了 list 并放入环境选项

env: 
 CF_DOCKER_PASSWORD:test

我尝试搜索信息
但我仍然不知道答案

Answer 1

这个...

env: 
 CF_DOCKER_PASSWORD:test

不是你想要的。这告诉cf cli设置应用程序可访问的环境变量。只有在您的应用程序启动后才能访问。我们需要先下载容器，然后才能运行它，因此在此处进行设置为时已晚。

您想在计算机上本地设置环境变量，以便在cf cli运行时知道要使用的密码。

因此，您想要...

Mac / Linux:

export CF_DOCKER_PASSWORD=test

视窗:

set CF_DOCKER_PASSWORD=test

然后，您可以运行 cf push --docker-image rocker/rstudio --docker-username rstudio-test。 cf cli将从您的本地环境变量读取密码并将其传递给平台，以便平台可以下载您的docker镜像。

作为FYI，Mac和Linux用户也可以执行 CF_DOCKER_PASSWORD=test cf push ...的缩写。我不相信这可以在Windows上运行。
