Question

我正在尝试在Dockerfile中执行npm install，但即使假设禁用颜色，颜色代码似乎仍然出现在Dockerhub构建日志中。

我可能做错了什么？

您可以在Docker Hub上找到包含构建详细信息的Dockerfile：https://hub.docker.com/r/amcsi/szeremi/builds/btk4utf3whezxqhnbzpkhyw/

Dockerfile：

FROM node
MAINTAINER  Attila Szeremi <attila+webdev@szeremi.com>
RUN mkdir /src
WORKDIR /src
RUN cd /src
# Copy just the package.json file file as a cache step.
COPY package.json /src/package.json
# Disable progress so npm would install faster.
# Disable colors, because Dockerhub can't display them.
# Install NPM packages excluding the dev dependencies.
RUN npm set progress=false && npm set color=false && npm install --production

COPY . .
RUN npm run build
EXPOSE  8080
CMD ["npm", "run", "start"]

Answer 1

对我有用的解决方案是@admin.register(Car) class CarAdmin(CustomAdmin): list_display = ('get_color',) def get_color(self, obj): return mark_safe('<a href="/admin/myapp/car/?color={}">{}</a>'.format(obj.color, obj.color))，我在此处找到：https://github.com/nodejs/docker-node/issues/225

Answer 2

FROM node表示node 6.5（目前最近于2016年9月发布）

如issue 225中所述，它附带一个进度条（您尝试禁用）和一个微调器。

尝试简单的测试用例：

FROM node:6.4.0

ENV NPM_CONFIG_PROGRESS false
ENV NPM_CONFIG_SPIN false

WORKDIR /app

RUN npm install express

或者通过复制.npmrc：

progress=false
spin=false

或者直接将--color false添加到npm install命令：

 npm --color false install --production

如果无效，请重新打开问题225，因为这是该问题的最新错误报告。

或者考虑使用AnsiColor Plugin在Jenkins中运行作业，至少支持f

自此回答（2016年10月）以来，问题225提到：

问题是你的Jenkins在控制台输出中不支持ANSI转义序列 Dockerfile中STDERR上的所有输出都由docker build打印为红色。正如@tianon所提到的那样，只需使用AnsiColor + Plugin就可以解决这个问题。

因此解决此问题的一种方法是忽略任何输出，如Zack Steinkamp中this comment of the issue 225 RUN npm install 2>&1所述。

npm install在Docker Hub上安装期间显示颜色
