Dockerfile CMD命令未执行
我写了这个Dockerfile。它应该构建应用程序，然后将其运行到我创建的容器中，但不起作用。当我使用该图像创建一个容器时，cmd命令不执行，并且网站未运行。但是，当i exec容器并手动键入它时，它起作用。
FROM node:16 as builder
WORKDIR /app
COPY ./package*.json ./
RUN npm install
COPY . .
RUN npm run build
FROM node:16
WORKDIR /app
RUN npm install serve
COPY --from=builder /app/build .
CMD ["npx", "serve"]
I wrote this Dockerfile. It should build the app and then run it into the container which I create, but it doesn't work. When I create a container with that image, CMD commands is not execute and the site is not running. But it works when I exec the container and type it manually.
FROM node:16 as builder
WORKDIR /app
COPY ./package*.json ./
RUN npm install
COPY . .
RUN npm run build
FROM node:16
WORKDIR /app
RUN npm install serve
COPY --from=builder /app/build .
CMD ["npx", "serve"]
