一、mysql软件

解压mysql软件到镜像目录

/data/image/mysql

二、编辑mysql配置文件

/data/image/my.cnf
[client]
port    = 3306
socket  = /data/mysql/data/mysql.sock

[mysql]
prompt="\\u@mysql \\R:\\m:\\s [\\d]> "

三、修改dockerfile

cd /data/image

echo '''FROM centos:7

COPY mysql /usr/local/mysql
COPY my.cnf /etc/my.cnf
RUN echo "export PATH=/usr/local/mysql/bin:$PATH" >> /etc/profile
RUN yum install -y libaio* numactl
RUN groupadd mysql && useradd mysql -g mysql && mkdir -p /data/mysql/{data,binlog,logs,tmp} && chown -R mysql.mysql /data/mysql
RUN /usr/local/mysql/bin/mysqld --defaults-file=/etc/my.cnf --initialize-insecure
ENTRYPOINT /usr/local/mysql/bin/mysqld_safe --defaults-file=/etc/my.cnf
'''> Dockerfile

四、构建镜像

docker build -t mysql8026 .

五、启动

docker run -itd --name mysql8.0.26 -p 33061:3306 mysql8026:latest /bin/bash
8ac398361b3bc429e458eb1da76f5542c77e3d08f1092e6d39c59c2ad22bb447

docker ps
coCONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                     NAMES

六、导出镜像

docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
mysql8026           latest              11f3a1fbd8b1        6 minutes ago       7.75 GB
docker.io/centos    7                   eeb6ee3f44bd        3 weeks ago         204 MB
docker save -o ./mysql8026_image.tar mysql8026:latest
