Galera群集Dockerfile

我正在尝试从这个链接http://galeracluster.com/documentation-webpages/docker.html创build一个基于这个dockerfile文件的galera docker镜像

FROM ubuntu:14.04 MAINTAINER your name <your.user@example.org> ENV DEBIAN_FRONTEND noninteractive RUN apt-get update RUN apt-get install -y software-properties-common RUN apt-key adv --keyserver keyserver.ubuntu.com --recv BC19DDBA RUN add-apt-repository 'deb http://releases.galeracluster.com/ubuntu trusty main' RUN apt-get update RUN apt-get install -y galera-3 galera-arbitrator-3 mysql-wsrep-5.6 rsync COPY my.cnf /etc/mysql/my.cnf ENTRYPOINT ["mysqld"] 

但是我得到这个错误

 W: Failed to fetch http://releases.galeracluster.com/ubuntu/dists/trusty/main/binary-amd64/Packages 404 Not Found E: Some index files failed to download. They have been ignored, or old ones used instead. 

你能帮我么 !! 它曾经在两周前为我工作的很好! 任何想法 ??
