我已经为我的ReactJS应用程序构建了Docker镜像。我在本地运行该图像并进行了测试,效果很好。
我正在使用Google Cloud Build,它会自动将我的容器映像放到gcr.io容器存储库中。
然后我尝试从驻留在gcr.io中的容器映像创建部署
但是部署未成功完成。它给了我
Pod错误:CrashLoopBackOff
没有最低可用性
这是我的Docker映像。
FROM node:latest
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY package.json .
RUN npm install
COPY . ./
EXPOSE 3000
CMD [ "npm", "start" ]
当我查看pod->容器日志时,我看到我的应用已重新启动,没有任何错误日志。

我怀疑会发生什么,kubernetes没有等待足够的时间来尝试重新启动应用程序。
我不是在使用Deployment.yaml,而是在使用GCP控制台。 我的ReactJS应用程序中没有运行状况终结点。
