我想基于centos 7构建一个docker镜像,dockerfile如下
FROM centos
MAINTAINER pengji jipeng92@gmail.com
WORKDIR /root
COPY MySQL-5.6.26 /mysql
RUN yum update
RUN yum -y install java-1.8.0-openjdk wget httpd php php-mysqlnd /mysql/*
RUN mysql_install_db --user=mysql
ENV MYSQL_ROOT_PASSWORD=root
ENV MYCAT_USER mycat
ENV MYCAT_PASS mycat
RUN wget http://mirror.bit.edu.cn/apache/tomcat/tomcat-7/v7.0.64/bin/apache-tomcat-7.0.64.tar.gz
RUN tar xvf apache-tomcat-7.0.64.tar.gz -C /usr/local/ && mv /usr/local/apache-tomcat-7.0.64/ /usr/local/tomcat
RUN wget http://code.taobao.org/svn/openclouddb/downloads/old/MyCat-Sever-1.2/Mycat-server-1.2-GA-linux.tar.gz
RUN mkdir /usr/local/mycat && tar xvf Mycat-server-1.2-GA-linux.tar.gz -C /usr/local/mycat && useradd mycat && \
chown -R mycat.mycat /usr/local/mycat && chmod a+x /usr/local/mycat/bin/*
EXPOSE 8080 8066 9066
COPY /home/jipeng/dockerfiles/dataguru/java_tomcat_mysql/startup.sh /root/startup.sh
RUN chmod a+x /root/startup.sh
ENTRYPOINT /root/startup.sh
然后通过命令构建
docker build -t pengji/mycat .
过程如下

One of the configured repositories failed (Unknown),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Disable the repository, so yum won't use it by default. Yum will then
just ignore the repository until you permanently enable it again or use
--enablerepo for temporary usage:
yum-config-manager --disable <repoid>
4. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
Cannot find a valid baseurl for repo: base/7/x86_64
我怎么解决这个问题?谢谢你。
最佳答案
也许您设置了 http_proxy 并且您的代理服务器未访问。
取消设置 http_proxy
关于docker - 找不到 repo : base/7/x86_64 when build docker image 的有效 baseurl,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/35824894/
