docker - 在Docker上服务Vue js应用程序

Question

我想将我的vueJs应用程序 jetty 化。在本地计算机上，我可以通过运行命令 npm install 和 npm run serve 在本地主机上安装和提供服务。

我想创建一个docker镜像，所以我写了一个dockerfile。我的dockerfile看起来像这样

FROM Image_Name

WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 8080
CMD ["npm", "serve"]

但是我无法使用docker run命令运行我的docker镜像。知道我在做什么错。

运行run命令后-

Usage: npm <command>

where <command> is one of:
    access, adduser, audit, bin, bugs, c, cache, ci, cit,
    completion, config, create, ddp, dedupe, deprecate,
    dist-tag, docs, doctor, edit, explore, get, help,
    help-search, hook, i, init, install, install-test, it, link,
    list, ln, login, logout, ls, outdated, owner, pack, ping,
    prefix, profile, prune, publish, rb, rebuild, repo, restart,
    root, run, run-script, s, se, search, set, shrinkwrap, star,
    stars, start, stop, t, team, test, token, tst, un,
    uninstall, unpublish, unstar, up, update, v, version, view,
    whoami

npm <command> -h     quick help on <command>
npm -l           display full usage info
npm help <term>  search for help on <term>
npm help npm     involved overview

Specify configs in the ini-formatted file:
    /root/.npmrc
or on the command line via: npm <command> --key value
Config info can be viewed via: npm help config

npm@6.2.0 /usr/lib/node_modules/npm

当您尝试执行时npm run serve 你应该把
Dockerfile中的CMD ["npm", "run", "serve"]。
您缺少run部分。
