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 命令的高斯测试，但是测试失败了，因为路径变量（在Dockerfile中） - 由于某种原因 - 没有保持设置。

我也尝试从Dockerfile内部获取.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

乍一看并不是很清楚，但PATH周围的双引号并不是一个好的unicode角色。您应该使用通常的"替换它们，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

设置PATH变量并在Dockerfile中获取env
