docker - 设置 PATH 变量并在 Dockerfile 中获取环境

Question

我编写了一个 Dockerfile 来创建安装了 Golang 的容器。我有一个运行 go version 命令的 goss 测试，但测试失败，因为路径变量(在 Dockerfile 中)——出于某种原因——没有保持设置。

我也曾尝试从 Dockerfile 中获取 go 的 .env，但这似乎也不起作用。

Dockerfile

ENV GIMME_VERSION "v1.4.0"
ENV GO_VERSION "1.4"
ENV JENKINS_HOME "/opt/jenkins"
ENV PATH="~/bin:${PATH}"
ENV PATH=“/opt/jenkins/.gimme/versions/go1.4.linux.amd64/bin:${PATH}“
ENV GOROOT="/opt/jenkins/.gimme/versions/go${GO_VERSION}.linux.amd64"

USER root

RUN yum -y install git && \
    yum -y clean all && \
    rm -rf /var/cache/yum

WORKDIR $JENKINS_HOME

USER jenkins

RUN mkdir ~/bin && \
    curl -sL -o ~/bin/gimme https://raw.githubusercontent.com/travis-
    ci/gimme/${GIMME_VERSION}/gimme && \
    chmod +x ~/bin/gimme && \
    gimme ${GO_VERSION}

USER root

RUN source /opt/jenkins/.gimme/envs/go${GO_VERSION}.linux.amd64.env

    exists: true
    mode: '0755'
command:
  'gimme version':
  exit-status: 0
  'go version':
  exit-status: 0

乍一看不是很清楚，但是PATH 周围的双引号 不是好的unicode 字符。您应该将它们替换为通常的 "，而不是 “(Unicode UTF8 代码点 U+201C)

演示:不一样:

$ od -c <<< \"
0000000   "  \n
0000002
$ od -c <<< \“
0000000 342 200 234  \n
0000004
