DockerFile

来自节点：12 alpeas-build-WORKDIR/usr/src/sample-COPY-package。json/usr/src/sample/package。json运行cd/usr/src/sample运行npm安装拷贝/usr/src/sample

运行npm运行构建登录

建立 /usr/src/sample/dist/myapp /usr/share/nginx/html/dv/sampleapp

打包的。json文件我有“构建登录”：“npm运行构建内存

Answer 1

我建议使用此Dockerfile：

# stage 1
FROM 12-alpine as builder

WORKDIR /usr/src/sample
COPY .  /usr/src/sample/
RUN npm install @angular/cli -g
RUN npm i
# A head-of-time compilation
RUN ng build --prod

# stage 2
FROM nginx:1.17.1-alpine
RUN rm -rf /usr/share/nginx/html/*
COPY --from=builder /usr/src/sample/dist/myapp /usr/share/nginx/html/
CMD ["nginx", "-g", "daemon off;"]

Answer 2

尝试这个DockerFile：

# Stage 1
FROM node:12-alpine AS build 
WORKDIR /usr/src/sample 
COPY package.json .
# no need for this since you put your workdir path
# RUN cd /usr/src/sample 
RUN npm install 
COPY . .

# Stage 2
FROM nginx:1.17.1-alpine 
COPY --from=build /usr/src/sample/dist/myapp /usr/share/nginx/html/

如果你能将你的图像版本升级到最新版本（节点：13.8-alpine和nginx:1.17.8-alpine）会更好。另外，如果您可以在本地运行构建cmds（尤其是生产构建），以查看它是否正常工作或崩溃。
