docker - 在debian中找不到Docker npm:jessie20180831

Question

我的Dockerfile

FROM debian:jessie-20180831 as builder
ENV BUILD_DEPS "curl git"

COPY . /go/src/chaochaogege.com/onlinecode
WORKDIR /go/src/chaochaogege.com/onlinecode
RUN apt-get update && apt-get install curl git sudo --no-install-recommends -y
RUN curl -sL https://deb.nodesource.com/setup_8.x | sudo -E sh -;\
    apt-get install nodejs -y --no-install-recommends;

RUN cd ./client-side \
    && npm install && npm run build;
COPY ./sql ./client-side/dist/

RUN apt-get update && apt-get install ${BUILD_DEPS} -y --no-install-recommends;\
    curl https://raw.githubusercontent.com/golang/dep/master/install.sh | sh; \
    dep ensure -update;\
    go install;

FROM golang:1.11.1-alpine3.7
RUN mkdir -p /go/src/chaochaogege.com/onlinecode
WORKDIR /go/src/chaochaogege.com/onlinecode
COPY --from=builder /go/bin/onlinecode .
COPY --from=builder /go/src/chaochaogege.com/onlinecode/client-side/dist/* .
EXPOSE 8086
ENTRYPOINT ["onlinecode"]

我不知道我的事
在我看来，我将nodejs安装在RUN层中，然后在其后的另一层中使用npm。

但是为什么不行呢？

我敢肯定有一些棘手的问题，但是所有这些都不能解决我的问题。

我想也许npm只能在同一docker层中使用？因此，我将Dockerfile更改为:

FROM debian:jessie-20180831 as builder
ENV BUILD_DEPS "curl git"

COPY . /go/src/chaochaogege.com/onlinecode
WORKDIR /go/src/chaochaogege.com/onlinecode
RUN apt-get update && apt-get install curl git sudo --no-install-recommends -y
RUN curl -sL https://deb.nodesource.com/setup_8.x | sudo -E sh -;\
    apt-get install nodejs -y --no-install-recommends;\
    npm --version; \
    cd ./client-side \
    && npm install && npm run build;

COPY ./sql ./client-side/dist/

RUN apt-get update && apt-get install ${BUILD_DEPS} -y --no-install-recommends;\
    curl https://raw.githubusercontent.com/golang/dep/master/install.sh | sh; \
    dep ensure -update;\
    go install;

FROM golang:1.11.1-alpine3.7
RUN mkdir -p /go/src/chaochaogege.com/onlinecode
WORKDIR /go/src/chaochaogege.com/onlinecode
COPY --from=builder /go/bin/onlinecode .
COPY --from=builder /go/src/chaochaogege.com/onlinecode/client-side/dist/* .
EXPOSE 8086
ENTRYPOINT ["onlinecode"]

还能得到结果

npm not found

错误记录

Answer 1

使用apt-get install nodejs，您仅安装节点，而不安装npm本身。您可以在debian package index中检查nodejs文件。

要安装npm，您需要安装npm package。

因此，要修复您的Dockerfile，请编辑以下行:
apt-get install nodejs -y --no-install-recommends;
带有:
apt-get install nodejs npm -y --no-install-recommends;
