COPY plugins.sh /usr/local/bin/plugins.sh
# Adding required plugins
COPY plugins.txt /plugins.txt
RUN cd /usr/local/bin && ls -al && echo 'Hello'
RUN /usr/local/bin/plugins.sh /plugins.txt

其输出为:

这又给了我一个错误:

这是个小错误,但它给了我们一个重要的教训:

执行Dockerfile时,对于我们从本地复制到docker容器的所有文件,权限将始终保持原样,并且不能更改。

主机上的权限:

-rw-rw-r--  1 sevenos sevenos 1301 Jun 11 12:30 jenkins.sh
-rw-rw-r--  1 sevenos sevenos 3917 Jun 11 12:30 plugins.sh
-rw-rw-r--  1 sevenos sevenos  806 Jun 11 12:30 plugins.txt

Docker中的权限:

Step 64/73 : RUN cd /usr/local/bin && ls -al && echo 'Hi'
 ---> Running in 71c1dff30ffc
