【gitlab+jenkins+docker】手把手教你搭建基于gitlab+jenkins+docker的项目的自动化部署流程
前言
使用现成的docker容器能够快速搭建mysql服务，且管理起来很方便，具有容灾、可移植等优点，本架构需要维护一张docker容器信息表，以做到ip和port等信息的统一分发与管理
路径创建
为了避免不必要的错误，建议数据存放路径与我这里保持一致：
[root@JackRoy ~]# mkdir -p /opt/dockers/docker_db_mysql/online
[root@JackRoy ~]# mkdir -p /opt/dockers/docker_db_mysql/mysql_data/conf
[root@JackRoy ~]# vim /opt/dockers/docker_db_mysql/mysql_data/conf/my.cnf
[mysqld]
user=mysql
default-storage-engine=INNODB
character-set-server=utf8
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[root@JackRoy ~]# mkdir -p /opt/dockers/docker_db_mysql/mysql_data/db
[root@JackRoy ~]# mkdir -p /opt/dockers/docker_db_mysql/mysql_data/init
[root@JackRoy ~]# vim /opt/dockers/docker_db_mysql/mysql_data/init/init.sql
create database common charset utf8;
use common;
grant all on common.* to 'common'@'localhost' identified by 'common_user@1235';
grant all on common.* to 'common'@'%' identified by 'common_user@1235'
封装docker启动命令
这里借用一下同事刘某源（感谢老源~）编写的docker启动命令，直接编辑输入：
[root@JackRoy online]# vim /usr/bin/dockerutils
#!/bin/bash
# Settle issue (e.g.: SELINUX) of when mount host directory, it has no privilege to access.
chcon -Rt svirt_sandbox_file_t $dir > /dev/null 2>&1
container_name=
TOP_PID=$$
trap 'exit 127' TERM
gate_way=`route | grep 'default' | awk '{print $2}'`
code=0
find_name(){
_container_name=`cat $dir/docker-compose.yml | grep container_name | awk -F ':' '{print $2}' | sed 's/^[ ]*//g' | sed 's/[ ]*$//g'`
_container_name=${_container_name//\"/}
container_name=${_container_name//\'/}
if [ x$container_name == x ]
then
echo -e "\033[31mERROR : please set container_name in your docker-compose.yml file \033[0m"
kill -s TERM $TOP_PID
fi
}
check(){
_host_name=`cat $dir/docker-compose.yml | grep hostname | awk -F ':' '{print $2}' | sed 's/^[ ]*//g' | sed 's/[ ]*$//g'`
_host_name=${_host_name//\"/}
host_name=${_host_name//\'/}
echo "-------------------------------------------------"$host_name
if [ x$host_name == x ]
then
echo -e "\033[31mERROR : hostname not set ! \033[0m"
code=1
fi
_ip=`cat $dir/docker-compose.yml | grep ipv4_address | awk -F ':' '{print $2}' | sed 's/^[ ]*//g' | sed 's/[ ]*$//g'`
_ip=${_ip//\"/}
ip=${_ip//\'/}
if [ $1 = y ] ; then
fail=`ping $ip -c 3 -s 1 -W 1 | grep "100% packet loss" | wc -l`
if [ $fail -eq 0 ]
then
echo -e "\033[31mERROR : address is already in use \033[0m"
code=1
fi
fi
if [ $code -ne 0 ] ; then kill -s TERM $TOP_PID ;fi
}
up(){
check n
docker-compose -f $dir/docker-compose.yml up -d
start
}
reup(){
docker rm -f $container_name
up
}
start(){
docker start $container_name
}
stop(){
docker stop $container_name
}
restart(){
docker stop $container_name
sleep 3
docker start $container_name
}
usage(){
echo -e " Usage : \n \t $0 [ usage ] | < up | reup | start | stop | restart > "
echo -e "\t ============= nat docker ==============="
echo -e "\t up : create container and start app"
echo -e "\t reup : re-create container and start app"
echo -e "\t start : start container and app"
echo -e "\t stop : stop container and app"
echo -e "\t restart : restart container and app"
kill -s TERM $TOP_PID
}
if [ "$1"x = ""x ] || [ "$1"x = "usage" ] ; then
usage
fi
find_name
$@
exit $?
创建启动配置文件
进入/opt/dockers/docker_db_mysql/online目录下：
[root@JackRoy online]# cd /opt/dockers/docker_db_mysql/online
编辑deploy_comm.sh并输入：
#!/bin/bash
dir=$(cd -P -- "$(dirname -- "$0")" && pwd -P)
. dockerutils $@
编辑docker-compose.yml并输入：
version: '2.2'
services:
mysqlcommon55:
image: "docker.io/mysql:5.5"
container_name: mysql-common
hostname: mysql-common
restart: always
volumes:
- "../mysql_data/db:/var/lib/mysql"
- "../mysql_data/conf/my.cnf:/etc/my.cnf"
- "../mysql_data/init:/docker-entrypoint-initdb.d/"
cpus: "1"
mem_limit: "256M"
environment:
MYSQL_ROOT_PASSWORD: "root@123"
MYSQL_USER: 'common'
MYSQL_PASS: 'common@123'
ports:
- "3307:3306"
networks:
aidata_network:
ipv4_address: 10.111.113.20
networks:
aidata_network:
external: true
启动
在/opt/dockers/docker_db_mysql/online路径下，执行启动命令：
# deploy_comm.sh 支持 reup up stop多种命令
[root@JackRoy online]# sh deploy_comm.sh reup
Error response from daemon: No such container: mysql-common
-------------------------------------------------mysql-common

执行启动命令以后我们进入docker容器，如果能成功进入并进入mysql那便是执行成功了：
[root@JackRoy online]# docker exec -it mysql-common bash
root@mysql-common:/# mysql -uroot -proot@123
