Python couchbase连接在尝试访问docker中的数据库时引发错误

Question

我从一个python脚本中得到以下错误，该脚本首先在docker中启动couchbase实例，然后尝试连接到couchbase数据库

如果我已经单独启动了容器，那么python couchbase连接就可以正常工作，但是如果代码试图在同一个python脚本中启动docker couchbase容器和连接，则会抛出连接错误

这是错误

下面是python代码

from couchbase.cluster import Cluster, ClusterOptions
from couchbase_core.cluster import PasswordAuthenticator
import docker
import time

client = docker.from_env()


def remove_e2e_container():
    docker_containers = client.containers.list()
    for container in docker_containers:
        if container.name == 'e2e_container':
            container.remove(force=True)


def create_container():
    remove_e2e_container()
    client.containers.run('bentonam/couchbase-docker', name='e2e_container', detach=True,
                          environment=["CLUSTER_RAMSIZE=500", "BUCKET_RAMSIZE=500",

                              8094, '11210/tcp': 11210})


create_container()


config = {
    'login': 'Administrator',
    'password': 'password',
    'host': "couchbase://localhost",
    'schema': 'accums_e2e_test'
}

authenticator = PasswordAuthenticator(config.get('login'), config.get('password'))
cluster = Cluster('couchbase://localhost', ClusterOptions(authenticator))
cb = cluster.bucket('accums_e2e_test')

results = cb.query("CREATE PRIMARY INDEX ON `accums_e2e_test`")


for i in results:
    print(i)
