Docker和RabbitMQ :如何在删除服务后重新启动服务

Question

我正在尝试使用docker创建一个rabbitmq集群，基于下面这两个链接中提供的详细信息，我已经启动了它，但不确定如何在再次删除它之后启动图像/容器。

第二个视频是他用这个命令停止一个节点(请原谅这个名字，还不知道如何使它更简洁)。

docker rm -f rabbitcluster_rabbit_node_3_1

因此，我的问题是，我如何启动第三个，我刚刚删除了上面？目前，我已经尝试了这个命令，它是图像名，但get似乎是单独启动的。

docker run -d rabbitcluster_rabbit_node_3

​

​

我可以使用来自docker-compose.yml的任何东西，还是必须使用docker运行，因为它现在似乎与docker-come.yml文件断开了！？

这是我写的docker-compose.yml

version: "3.9"

services:
    rabbit_node_1:
        build: .
        hostname: rabbit-1
        environment:
            - RABBITMQ_ERLANG_COOKIE = "ABCDYJLFQNTHDRZEPLOZ"
            - RABBIT_NODENAME = rabbit1
            - RABBITMQ_CONFIG_FILE = /etc/rabbitmq/rabbitmq.conf
            - RABBITMQ_SERVER_ADDITIONAL_ERL_ARGS = -rabbit log [{console,[{level,debug}]}]
        ports: 
            - 8081:15672
            - 5672:5672
            - 4369:4369
            
    rabbit_node_2:
        build: .
        hostname: rabbit-2
        # Don't start any of these until rabbit1 is up
        depends_on: 
            - rabbit1
        environment:
            - RABBITMQ_ERLANG_COOKIE = "ABCDYJLFQNTHDRZEPLOZ"
            - RABBIT_NODENAME = rabbit2
            - RABBITMQ_CONFIG_FILE = /etc/rabbitmq/rabbitmq.conf
            - RABBITMQ_SERVER_ADDITIONAL_ERL_ARGS = -rabbit log [{console,[{level,debug}]}]
        ports: 
            - 8082:15672
            
    rabbit_node_3:
        build: .
        hostname: rabbit-3
        # Don't start any of these until rabbit1 is up
        depends_on: 
            - rabbit1
        environment:
            - RABBITMQ_ERLANG_COOKIE = "ABCDYJLFQNTHDRZEPLOZ"
            - RABBIT_NODENAME = rabbit3
            - RABBITMQ_CONFIG_FILE = /etc/rabbitmq/rabbitmq.conf
            - RABBITMQ_SERVER_ADDITIONAL_ERL_ARGS = -rabbit log [{console,[{level,debug}]}]
        ports: 
            - 8083:15672


# docker network create rabbitmq-cluster
networks:
    default:
        name: rabbitmq-cluster

这是Dockerfile

FROM rabbitmq:3.9-management

COPY rabbitmq.conf /etc/rabbitmq/rabbitmq.conf
COPY definitions.json /etc/rabbitmq/definitions.json
COPY .erlang.cookie /var/lib/rabbitmq/.erlang.cookie

RUN chmod 700 /var/lib/rabbitmq/.erlang.cookie

这是rabbitmq.conf

loopback_users.guest = false
listeners.tcp.default = 5672
management.listener.port = 15672
management.listener.ssl = false
management.load_definitions = /etc/rabbitmq/definitions.json
cluster_name = cluster1
cluster_formation.peer_discovery_backend = rabbit_peer_discovery_classic_config
cluster_formation.classic_config.nodes.1 = rabbit@rabbit-1
cluster_formation.classic_config.nodes.2 = rabbit@rabbit-2
cluster_formation.classic_config.nodes.3 = rabbit@rabbit-3

最后，这是rabbitmq definitions.json文件。

        {
            "name": "andrew", 
            "password": "test",

        }
    ], 
    "vhosts": [
        {
            "name": "/"
        }
    ], 
    "permissions": [
        {
            "user": "andrew", 
            "vhost": "/",

            "write": ".*",

        }
    ],

            "durable": true, 
            "auto_delete": false, 
            "internal": false, 
            "arguments": {}
        }
    ],
    "queues": [

            "vhost": "/", 
            "durable": true, 
            "auto_delete": false, 
            "arguments": {}
        }
    ], 
    "bindings": [

            "source": "test.exchange", 
            "vhost": "/",

            "destination_type": "queue",
            "routing_key": "",
            "arguments": {}
        }
    ]
}

命令docker rm -f (强制)移除容器。在那之后你不能再启动它了，因为它已经不存在了。

如果要从docker-compose文件中的服务docker-compose创建新容器，则需要在docker-compose.yml所在的目录中使用docker-compose命令：

docker-compose up -d rabbit_node_3

其中：

• up告诉对接者-撰写从命名的服务创建容器，(rabbit_node_3)
• -d告诉对接者-撰写，你不想把你的终端附加到容器的stdout和stderr上，由这个命令启动。它只会在后台释放您的终端来执行其他任务，
