如何在中间容器中使用NPM配置文件？

Question

尝试时

docker build \
--tag my-app:latest \
.

与以下 Dockerfile:

FROM node:9-stretch AS intermediate

ARG NPM_TOKEN

COPY [".npmrc", "./"]

RUN ["chmod", "0600", ".npmrc"]

COPY ["package.json", "./"]

RUN ["npm", "install"]

FROM node:9-stretch

WORKDIR /usr/src/app/

COPY --from=intermediate ["node_modules/.", "./node_modules/."]

COPY ["package.json", "index.js", "./"]

CMD ["node", "index.js"]

以及以下.npmrc：

//registry.npmjs.org/:_authToken=${NPM_TOKEN}

我在 intermediate 容器的步骤 Step 6/14 : RUN ["npm", "install"] 中收到以下错误：

我的 Bash shell 的 .bashrc 和 Z shell 的 .zshrc 中也有以下行：

export NPM_TOKEN=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

我正在按照找到的 here.

官方 NPM 文档以这种方式将 node_modules 添加到我的 Docker 图像中

Answer 1

你就快完成了！

根据您链接的官方 NPM 文档，您的 docker build 命令只缺少 --build-arg 选项，提到了 here and detailed here。

您完成的命令应该是：

docker build \
--build-arg NPM_TOKEN=${NPM_TOKEN} \
--tag my-app:latest \
.
