python-py开启容器并绑定静态ip

随机一个ip检测是否可用

import random
def get_available_ip(request):
    ipBase = '10.10.0.'
    while true:
        num = random.randint(2,254)
        ip = ipBase + str(num)
        if subprocess.call(["ping", "-c", "2", ip]) != 0:  # 只发送两个ECHO_REQUEST包
            return HttpResponse(json.dumps(({"ip": ip})))
            #print("{0} is alive.".format(ip))
    return None
    

连接到本地创建容器

def create_staticip_docker(request):
    if request.method == "GET":
        new_ip = request.GET.get('ip')
        image = request.GET.get('image')
        images = docker_img.objects.get(img_name=image)
        user = UserProfile.objects.get(username='admin')
        node = docker_node.objects.get(ip='127.0.0.1')


        base_url = 'tcp://' + node.ip + ':2375' #连接到本地
        client = docker.DockerClient(base_url=base_url, version='auto', timeout=10)
        images_name = images.img_name
        command = images.command
        #设置容器名称
        docker_name_base = user.username
        docker_num = container.objects.all().count() + 1
        docker_name = docker_name_base + str(docker_num)
        #容器归到static网络中
        assign_network = 'static'

        #建立并开启容器
        new_docker = client.containers.run(images_name, detach=True, tty=True, stdin_open=True, name=docker_name,command=command)
        dockernet = client.networks.get(assign_network)
        dockernet.connect(new_docker, ipv4_address=new_ip)
        bridgenet = client.networks.get('bridge')
        bridgenet.disconnect(new_docker)

        new_container = client.containers.get(docker_name)
        ip_addr = new_container.attrs['NetworkSettings']['Networks']['static']['IPAddress']
        print(ip_addr)
        mydocker = container.objects.create(Only_Id=new_docker.id,name=docker_name,user=user,cpu_cores=1,memory=1,img=images,region=node.belong,node=node,portmap=None)
        mydocker.save()
        return HttpResponse(json.dumps(({"ip": ip_addr})))
