我是Docker的新手,尝试用简单的Dockerfile构建一个图像:
FROM jenkins
USER root
RUN mkdir -pv /home/a/b
RUN touch /home/a/b/test.txt
RUN mkdir -pv /var/jenkins_home/a/b
RUN touch /var/jenkins_home/a/b/test.txt
USER jenkins
当我构建它时,它失败并输出以下内容:
Step 0 : FROM jenkins
Step 1 : USER root
Step 2 : RUN mkdir -pv /home/a/b
mkdir: created directory '/home/a'
mkdir: created directory '/home/a/b'
Step 3 : RUN touch /home/a/b/test.txt
Step 4 : RUN mkdir -pv /var/jenkins_home/a/b
mkdir: created directory '/var/jenkins_home/a'
mkdir: created directory '/var/jenkins_home/a/b'
Step 5 : RUN touch /var/jenkins_home/a/b/test.txt
touch: cannot touch '/var/jenkins_home/a/b/test.txt': No such …
