我在Docker上的Docker有問題（通過Docker Toolbox）。可能有人可以幫忙。ONBUILD選項出現錯誤（Windows中的Docker工具箱）
我Dockerfile沒有ONBUILD：
FROM node:5.9.1
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
COPY package.json /usr/src/app/
RUN npm install
COPY . /usr/src/app
CMD [ "npm", "start" ]
EXPOSE 3000
工作正常（搬運工建立-t測試並啓動它：搬運工運行 - 它--rm --name testrun測試） 但如果我改變Dockerfile到ONBUILD選項：
FROM node:5.9.1
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app
ONBUILD COPY package.json /usr/src/app/
ONBUILD RUN npm install
ONBUILD COPY . /usr/src/app
CMD [ "npm", "start" ]
EXPOSE 3000
我得到一個錯誤：
npm info it worked if it ends with ok
npm info using [email protected]

我做錯了什麼？ （即時通訊新手在Docker :)）。也許我錯了使用ONBUILD？但是就像沒有明確的事情一樣，沒有。
