reactjs - 支架和create-react-app停止工作

Question

几个月都工作良好，两天前退出工作。不要忘记更改.yamls中的任何内容。

基本上，当我启动create-react-app时，create-react-app客户端只是启动，失败并重新启动。

我试过了:

在工作时恢复到先前的提交

降级/升级skaffold

降级/升级minikube

降级/升级kubectl

测试Ubuntu 19.10，macOS 10.15.3和Windows 10(WSL2)，问题在所有

中仍然存在
skaffold和 create-react-app似乎是一个问题，因为以下情况仍然可以正常使用:

api和postgres pods 仍然可以启动并运行得很好

以下对我而言正常工作，这表明它不是create-react-app问题:

cd client
npm install
npm start

以下内容也正常工作，对我来说，这不是docker问题:

cd client
docker build -f Dockerfile.dev .
docker run -it -p 3000:3000 <image_id>

我认为这不是Kubernetes的问题。我推送到我的暂存分支，触发了暂存CI / CD管道，通过了构建和部署，它在我的暂存URL上正常运行。

这是我的配置:

我在这里有一个测试仓库，您可以尝试以下操作:

https://github.com/eox-dev/skaffold-cra-error

希望这只是我所忽略的事情，但是就像我说过的那样，我已经将应用程序还原到知道它可以正常工作的状态，但问题仍然存在。

编辑4/1
当我在 v1.6.0-docs发行说明中阅读此内容时，我很希望:

Note: This release comes with a new config version v2beta1. To upgrade your skaffold.yaml, use skaffold fix. If you choose not to upgrade, skaffold will auto-upgrade as best as it can.

但是，仍然存在相同的问题。

这是由于facebook/create-react-app(特别是#8739和#8688)发生了变化。您会注意到，如果在不分配TTY的情况下运行，则容器会立即从docker退出:

$ docker run --rm client; echo ">> $?"

有一个解决问题的方法，可以在Dockerfile中设置 CI=true:
