Docker mysql容器无法使用启动时定义的数据卷
我在尝试运行装载了数据卷的mysql容器时遇到了一个问题 以下是dockerfile:Docker mysql容器无法使用启动时定义的数据卷,mysql,docker,volume,Mysql,Docker,Volume,我在尝试运行装载了数据卷的mysql容器时遇到了一个问题 以下是dockerfile: from ubuntu:14.04 maintainer Tiago Pires, tandrepires@gmail.com # Because docker replaces /sbin/init: https://github.com/dotcloud/docker/issues/1024 RUN dpkg-divert --local --rename --add /sbin/initctl RU

# Because docker replaces /sbin/init: https://github.com/dotcloud/docker/issues/1024
RUN dpkg-divert --local --rename --add /sbin/initctl
RUN echo "deb http://archive.ubuntu.com/ubuntu trusty main universe" > /etc/apt/sources.list
RUN apt-get update && apt-get upgrade -y
ADD create_database.sql /tmp/create_database.sql
RUN apt-get install -y mysql-server
RUN sed -i -e"s/^bind-address\s*=\s*127.0.0.1/bind-address = 0.0.0.0/" /etc/mysql/my.cnf
RUN /usr/bin/mysqld_safe & \
sleep 10s && \
mysql -u root < /tmp/create_database.sql
VOLUME ["/var/lib/mysql", "/var/log/mysql"]
CMD ["mysqld_safe"]
现在我想显式定义一个文件夹来装载数据卷
docker run -d -p 3306:3306 \
-v $HOME/data:/var/lib/mysql \
-v $HOME/log:/var/log/mysql \
--name=sonar-sql sonar-sql
但这次我有一个错误:
150924 7:59:07 InnoDB: Operating system error number 13 in a file operation.
InnoDB: The error means mysqld does not have the access rights to
InnoDB: the directory.
InnoDB: File name ./ibdata1
InnoDB: File operation call: 'create'.
InnoDB: Cannot continue operation.
我看到数据文件夹已创建。我尝试更改权限并再次运行“”容器:
chmod a+wrX data
这次我有另一个错误:
150924 8:02:20 InnoDB: Completed initialization of buffer pool

现在数据文件夹的内容如下(一些必要的文件不存在):
Mysql进程是从容器内的Mysql用户运行的,该用户在主机上不存在

问:Docker文档说,VOLUME命令和-v选项也应该这样做,请解释为什么我可以使用VOLUME,但不能使用“-v”。
Ubuntu 14.04.2 LTS
Docker 1.6.0版,构建4749651,回答您的问题
有两种风格的-v
选项。实际上与VOLUME
指令相同,看起来像-v/var/lib/mysql-v/var/log/mysql
。它为容器定义了一个卷
您在示例中使用的表单是不同的,因为它将主机目录装载到容器的FS。看
ls -l
