Kubernetes 部署 Angular 前端崩溃答案

【问题描述】：

我正在尝试在 kubernetes 上部署 Angular 前端应用程序，但我总是收到此错误：

NAME                              READY   STATUS             RESTARTS   AGE
common-frontend-f74c899cc-p6tdn   0/1     CrashLoopBackOff   7          15m

当我尝试查看 pod 的日志时，它只打印空行，所以我怎样才能找出问题所在

这是 dockerfile，总是通过这个 dockerfile 构建管道：

### STAGE 1: Build ###

# We label our stage as 'builder'
FROM node:10.11 as builder

COPY package.json ./
COPY package-lock.json ./

RUN npm set progress=false && npm config set depth 0 && npm cache clean --force
ARG NODE_OPTIONS="--max_old_space_size=4096"
## Storing node modules on a separate layer will prevent unnecessary npm installs at each build
RUN npm i && mkdir /ng-app && cp -R ./node_modules ./ng-app

WORKDIR /ng-app

COPY . .

## Build the angular app in production mode and store the artifacts in dist folder
RUN $(npm bin)/ng build --prod --output-hashing=all

### STAGE 2: Setup ###

FROM nginx:1.13.3-alpine

## Copy our default nginx config
COPY nginx/default.conf /etc/nginx/conf.d/

## Remove default nginx website
RUN rm -rf /usr/share/nginx/html/*

## From 'builder' stage copy the artifacts in dist folder to default nginx public folder
COPY --from=builder /ng-app/dist /usr/share/nginx/html

CMD ["nginx", "-g", "daemon off;"]

和deployment.yaml

            port: 8080
          initialDelaySeconds: 30
          timeoutSeconds: 1

我真的不知道可能是什么问题，有人可以帮忙吗？谢谢！

【解决方案1】：

看起来 Kubernetes 未能通过 liveness 探测并将重新启动 pod。尝试评论“liveness probe”部分并重新开始。如果有帮助，请更正探测参数——超时、延迟等。

【解决方案2】：

嗯。您的容器死亡并尝试重新启动。首先，尝试查看他的日志和状态：

kubectl logs <container_name>
kubectl describe pod <container_name>
