我的Dockerfile创建一个目录,然后单击它,然后列出该目录.该目录仍由root拥有.这是为什么？

这是Dockerfile:

FROM ubuntu:precise
RUN useradd -d /home/testuser -m -s /bin/bash testuser
RUN mkdir -p /var/local/testrunner/logs
VOLUME ["/var/local/testrunner/logs"]
RUN grep testuser /etc/passwd
RUN grep root /etc/passwd
RUN chown -R testuser:testuser /var/local/testrunner/logs
RUN ls -ld /var/local/testrunner/logs 

这是"docker build"的输出:
