本文主要是介绍容器部署的openstack进入数据库流程、查看install目录流程、容器部署使用virsh命令流程【查看计算节点上的虚拟机信息】，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
说明
- 何为容器部署，无需多说吧？
如下 计算节点的容器
进入数据库方法【控制节点】
获取nova密码
首先获取nova数据库的密码
控制节点执行：grep mysql /etc/kolla/nova-api/nova.conf 【目录不是固定的，可以通过find命令查找nova.conf文件查看】，如下，1Gr2qFT0LmZ46v0GrFUJmXEFTTBHWVWzofxkxLAn就是密码
[root@controller01 ~]# grep mysql /etc/kolla/nova-api/nova.conf
connection = mysql+pymysql://nova:1Gr2qFT0LmZ46v0GrFUJmXEFTTBHWVWzofxkxLAn@10.241.101.240:3306/nova
connection = mysql+pymysql://nova_api:Msgi5FFcPqlkT26lDaH7wcceAE1cQNbsyzQ6TbzQ@10.241.101.240:3306/nova_api
[root@controller01 ~]#
查看数据库容器
肯定会有一个数据库容器的，如我这是mariadb
[root@controller01 ~]# docker ps

进入容器
[root@controller01 ~]# docker exec -it mariadb /bin/bash
(mariadb)[mysql@controller01 /]$ mysql -unova -p

查看install目录流程【计算节点】
查看容器
- nova_compute 和nova_libvirt 这2个容器都是可以查看实例目录的，进任意一个都行

进入容器
- 进入nova_libvirt查看
我这的实例目录是/var/lib/nova/instances/【你的如果不是就用find搜索instances即可】
[root@compute30 ~]# docker exec -it nova_libvirt bash
(nova-libvirt)[root@compute30 /]# cd /var/lib/nova/instances/
(nova-libvirt)[root@compute30 instances]# ls

使用virsh命令流程【计算节点】
查看容器
- virsh命令是基于libvirt服务的，所以我们这需要进入nova_libvirt容器
