docker存储卷

改变docker0的网段

[root@localhost ~]# docker run -d --name 123 httpd
f82635cd78acd496519e98bec326536681683613c35eac745a1c3aadbb5ca677
[root@localhost ~]# docker ps

[root@localhost ~]# docker inspect 123
                   "Gateway": "172.17.0.1",
                    "IPAddress": "172.17.0.2",
                    "IPPrefixLen": 16,
[root@localhost ~]# vim /etc/docker/daemon.json
{
          "registry-mirrors": ["https://2rdng78w.mirror.aliyuncs.com"],
          "bip": "192.168.1.1/24"
}

[root@localhost ~]# systemctl restart docker
[root@localhost ~]# docker inspect 123
                 "Gateway": "192.168.1.1",
                    "IPAddress": "192.168.1.2",
                    "IPPrefixLen": 24,

docker重启了123容器就停掉了，给他加这一段代码，就不会重启停掉容器
把之前的123容器删掉重新做

[root@localhost ~]# docker run -d --name 123 --restart=always httpd
1ca13f023ad98ba5d27a8f0470ee01d7456e26a519cd65f1c1cd924eb9b4796c

//总是重启

创建网桥

[root@localhost ~]# docker network create -d bridge --subnet "192.168.1.0/24" --gateway "192.168.1.1" qzl

给b1容器添加添加qzl网卡

设置镜像数据创建一个新的镜像

/ # mkdir data

存储卷管理存储卷的分类

Docker有两种类型的卷，每种类型都在容器中存在一个挂载点，但其在宿主机上的位置有所不同：

Bind mount volume
a volume that points to a user-specified location on the host file system
Docker-managed volume
the Docker daemon creates managed volumes in a portion of the host’s file system that’s owned bye Docker
容器中管理数据主要有两种方式：

数据卷（Data Volumes）
数据卷容器（Data Volumes Containers）

容器Volume使用语法： Docker-managed volume

docker run -it --name CONTAINER_NAME -v VOLUMEDIR IMAGE_NAME

[root@localhost ~]# docker run -it --rm --name b2 -v /data busybox /bin/sh
/ # ls
bin   data  dev   etc   home  proc  root  sys   tmp   usr   var
/ # cat data/123
cat: can't open 'data/123': No such file or directory
/ # cat data/abc 
/ # rm -f data/abc 
/ # 
[root@localhost ~]# docker inspect b2
"Source": "/var/lib/docker/volumes/de127a9d46b7616831a91fb508c2055bf60d7b9e546f6b94c79a3af86e5f9ad2/_data",
                "Destination": "/data",
[root@localhost ~]# cd /var/lib/docker/volumes/de127a9d46b7616831a91fb508c2055bf60d7b9e546f6b94c79a3af86e5f9ad2/_data
[root@localhost _data]# ls
[root@localhost _data]# touch abc
[root@localhost _data]# ls
abc
[root@localhost _data]# ls
[root@localhost _data]# 
  //和容器互联，删除容器都会被删除

Bind mount volume

[root@localhost ~]# docker run -it --rm --name b1 -v /qzl:/data busybox
/ # ls
bin   data  dev   etc   home  proc  root  sys   tmp   usr   var
/ # cd data
/data # ls
/data #

[root@localhost ~]# cd /qzl
[root@localhost qzl]# echo 'hello world' > index.123456
[root@localhost qzl]# ls
index.123456
[root@localhost qzl]# cat index.123456 
hello world

/data # ls
index.123456
/data # cat index.123456 
hello world

/data # exit
[root@localhost ~]# 
[root@localhost ~]# docker run -it --rm --name b1 -v /qzl:/data busybox
/ # ls
bin   data  dev   etc   home  proc  root  sys   tmp   usr   var
/ # cat data/index.123456 
hello world
/ # 
     //里面文件还在，因为主机的文件还在
