playbook與docker部署Wordpress

Docker部署wordpress：

需要運行兩個容器，一個mysql容器一個wordpress容器，他們都有自帶的一些變量，方便我們去部署他們

##############################################################################
mysql鏡像內置變量
MYSQL_ROOT_PASSWORD
MYSQL_USER
MYSQL_PASSWORD
MYSQL_DATABASE

創建MySQL容器
docker run --name mysql -d -p 3306:3306 -v data:/var/lib/mysql  \
> -e MYSQL_ROOT_PASSWORD=123 \
> -e MYSQL_DATABASE=wordpress \
> -e MYSQL_USER=tom \
> -e MYSQL_PASSWORD=123456  --restart always  10.30.5.120/docker/mysql:5.6

##############################################################################
wordpress鏡像內置的變量
WORDPRESS_DB_HOST            \\MySQL數據庫主機ip地址
WORDPRESS_DB_PORT                \\Mysql服務的端口
WORDPRESS_DB_NAME                \\數據庫的名字
WORDPRESS_DB_USER               \\登錄MySQL的用戶
WORDPRESS_DB_PASSWORD            \\登錄用戶密碼

創建wordpress容器
docker run --name wordpress -d -p 80:80 \
> -e WORDPRESS_DB_HOST=192.168.189.171 \
> -e WORDPRESS_DB_NAME=wordpress \
> -e WORDPRESS_DB_USER=tom \
> -e WORDPRESS_DB_PASSWORD=123456 --restart always --link mysql 10.30.5.120/docker/wordpress

部署wordpress:

劇本運行前語法：

檢查語法：ansible-playbook --syntax-check + name.yaml
列出執行任務： ansible-playbook --list-task + name.yaml
查看運行的主機： ansible-playbook --list-hosts + name.yaml
