node.js - 无法构建docker镜像

Question

我一直在尝试使用此 Dockerfile 构建 Docker 镜像:

FROM mhart/alpine-node:base-6

MAINTAINER techhadmin

COPY ./package.json src/

RUN cd src && npm install 

COPY . /src 

WORKDIR /src

EXPOSE 3000
CMD ["npm", "start"]

但我收到此错误:

/bin/sh: npm: not found
The command '/bin/sh -c cd src && npm install' returned a non-zero code: 127

知道如何解决这个问题吗？

Answer 1

阅读文档:

https://hub.docker.com/r/mhart/alpine-node/

写的是:

# If you need npm, don't use a base tag

# RUN npm install

所以不要使用 base-6 标签并将 FROM 图像更改为 7

FROM mhart/alpine-node:7
