Python 调用 Docker sdk

1、升级python3 (>3.8）和pip3

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel   wget http://npm.taobao.org/mirrors/python/3.9.0/Python-3.9.0.tgz   mv Python-3.9.0.tgz /usr/local/   tar -zxvf Python-3.9.0.tgz   cd python-3.9.0目录 ./configure prefix=/usr/local/python3   make && make install   ln -s /usr/local/python3/bin/python3.9 /usr/bin/python3 ln -s /usr/local/python3/bin/pip3.9 /usr/bin/pip3

2、安装

?

1 2	pip3   install docker pip3  install docker[tls]

3、使用默认套接字或环境中的配置连接到 Docker

?

1 2	import docker client = docker.from_env()

4、远程连接Docker

?

1 2 3 4 5 6 7 8

vim /lib/systemd/system/docker.service ExecStart=/usr/bin/dockerd -H  fd:// --containerd=/run/containerd/containerd.sock   -H tcp://0.0.0.0:8088 -H unix:///var/run/docker.sock   systemctl daemon-reload service docker restart   import docker client = docker.APIClient(base_url='tcp://ip:8088')  #这个ip是指上面操作中配置了远程访问功能docker的机器ip

5、包含的key如下：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

key: Id key: Created key: Path key: Args key: State key: Image key: ResolvConfPath key: HostnamePath key: HostsPath key: LogPath key: Name key: RestartCount key: Driver key: Platform key: MountLabel key: ProcessLabel key: AppArmorProfile key: ExecIDs key: HostConfig key: GraphDriver key: Mounts key: Config key: NetworkSettings

6、python 调用脚本

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54

import docker import os   ##获取认证信息 client = docker.from_env() #client = docker.APIClient(base_url='tcp://10.1.1.145:8088')  #这个ip是指上面操作中配置了远程访问功能docker的机器ip   def get_containers_info(con):     print('~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~')     ##指定某个具体的容器     container = client.containers.get(con)       ##容器名     name=container.attrs['Name']     print('容器名和CONTAINER ID：',name,container.short_id,end='\n\n')       ##容器使用的镜像     print('镜像：',container.attrs['Config']['Image'],end='\n\n')       ##容器的网络类型     a=container.attrs['HostConfig']['NetworkMode']     print('网络类型为:', a,end='\n\n')       ##端口暴露     g=container.attrs['HostConfig']['PortBindings']     print('端口：',g,end='\n\n')       ##容器的ip地址     #result = os.popen('docker inspect 2ce81c9cd060 | grep -w  IPAddress | sed -n 2p  | xargs | sed s/,//')     #print(result.read())       ip=container.attrs['NetworkSettings']['Networks']     #list(ip.keys())[0]['IPAddress']     #print(list(ip.keys())[0])     v=list(ip.values())[0]       print('ip 地址:',v['IPAddress'],end='\n\n')       c=container.attrs['State']['Status']     print('容器状态：',c,end='\n\n')       ##存储驱动     e=container.attrs['Driver']     print('存储驱动:',e,end='\n\n')       ##文件路径挂载     f=container.attrs['Mounts']     print('挂载情况：',f,end='\n\n')       print('~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~')   list1 = os.popen('docker ps -q').read().rstrip('\n').split('\n') for i  in list1:     get_containers_info(i)

注：

rstrip('\n') 是删除最后一行的空格

split('\n')   以换行符为切割

7、运行效果（虚拟机测试）
