本文解决在CentOS7环境下使用Docker构建基于Ubuntu的Flask应用镜像时遇到的源站无法解析问题。通过配置Docker的DNS服务器解决了apt-get命令无法正常工作的情况。

在centos7主机上构建docker镜像的时候写了如下的Dockerfile

FROM ubuntu:14.04 
RUN apt-get update 
RUN apt-get install -y python 
RUN apt-get install -y python-pip 
RUN apt-get clean all 
RUN pip install flask 
ADD hello.py /tmp/hello.py
EXPOSE 5000 
CMD ["python","/tmp/hello.py"]

使用docker build -t flask .命令构建的时候命令行报如下错误

Step 2/9 : RUN apt-get update

解析出现了问题，查了一些攻略，终于可以了。

在/etc/sysconfig/docker这个文件中，增加一行

# docker-latest daemon can be used by starting the docker-latest unitfile.
# To use docker-latest client, uncomment below lines
#DOCKERBINARY=/usr/bin/docker-latest
#DOCKERDBINARY=/usr/bin/dockerd-latest
#DOCKER_CONTAINERD_BINARY=/usr/bin/docker-containerd-latest
DOCKER_OPTS="–dns 8.8.8.8 –dns 8.8.4.4"
#DOCKER_CONTAINERD_SHIM_BINARY=/usr/bin/docker-containerd-shim-latest

然后重启docker服务

systemctl restart docker

重新运行构建命令

docker build -t flask .

apt-get命令运行正常
