Dockerfile’RUN git clone’删除中间容器

RUN git clone --verbose https://github.com/zsh-users/antigen ~/.antigen/antigen

该行的输出为：

Step 12 : RUN git clone --verbose https://github.com/zsh-users/antigen ~/.antigen/antigen
---> Running in 26cba91e912a
Cloning into '/root/.antigen/antigen'...
POST git-upload-pack (302 bytes)
---> e0012659884b
Removing intermediate container 26cba91e912a
Successfully built e0012659884b

(公共存储库的)克隆被删除,〜/ .antigen / antigen在容器中不存在.
“克隆到…”是红色的,因此我认为命令有问题.但是,如果我在容器的外壳中运行它(由docker run -it myimage打开),它将克隆它.

我是在做错什么,还是可以做一些设置以在dockerfile中使用git clone？这是它的全部内容：

$git clone --progress --verbose https://github.com/zsh-users/antigen 2&> /dev/null

在第一个命令中,我将所有STDOUT重定向到/ dev / null,我们仍然可以看到输出.但是在第二个命令中,我将所有STDERR重定向到了/ dev / null,所以我们什么也没看到.

在docker build中,如果STDOUT中没有任何输出,它将变为RED.而已.

因此,您的Dockerfile没问题.
