KILL -9 在 Kubernetes 容器中用于在构建时反应应用程序

KILL -9 in Kubernetes container for react app while building

我有一个反应应用程序,我想使用 docker 文件部署到 kubernetes,并使用 nginx 托管它。我的 Dockerfile 看起来像这样

FROM node:14-alpine as build

# Install git
RUN apk update && apk upgrade && \
    apk add --no-cache git

WORKDIR /src
COPY package*.json ./

RUN npm config set unsafe-perm true
RUN npm install
COPY . .
RUN npm run build

运行 kustomization 后我的 kuberetes 配置如下所示

  settings.ts.ctmpl: |
    export const LIGHTHOUSE_API_HOST = 'stageBackendURL';

      - emptyDir: {}
        name: lighthouse-web-config
      - emptyDir: {}
        name: lighthouse-web-static

当我部署它时,构建目录是空的。我尝试通过 ssh 连接到容器并手动构建它但出现此错误:

export NODE_OPTIONS=--max_old_space_size=4096 && react-scripts build

Creating an optimized production build...
The build failed because the process exited too early. This probably means the system ran out of memory or someone called `kill -9` on the process.
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! lighthouse@0.1.0 build: `export NODE_OPTIONS=--max_old_space_size=4096 && react-scripts build`
npm ERR! Exit status 1
npm ERR!

我早些时候将内存和 cpu 保持在 1gi 和 100m,但尝试增加到 16Gi 和 8Gi 但仍然没有用。

关于上面的几点说明:

1:我会使用多阶段 Dockerfile 构建,整个构建过程发生在节点容器中,但最终、完整、构建的应用程序随后被复制到基于 nginx 的容器中,例如

FROM node as build
...
FROM nginx
COPY --from=build /path/to/app /usr/share/nginx/html

2:npm 构建是昂贵的过程,在您的 kube 环境中进行 npm 构建,设置合理的 运行 时间限制,很可能 运行 出现您在此处提到的问题。

3:确保在您的 workstation/build 系统
