在 Dockerfile 中配置 RabbitMQ

Question

我有一个 Dockerfile，在其中安装 RabbitMQ 并执行一些配置（例如创建虚拟主机和交换）。不幸的是，当我从该 Dockerfile 启动容器时，配置不可用，并且我只有一个空白的 RabbitMQ 实例。如何在 Dockerfile 中预配置 RabbitMQ？这是我当前的 Dockerfile：

FROM node:16-bullseye

# install rabbitmq
RUN apt-get update && apt-get install -y erlang rabbitmq-server

# enable default rabbitmq plugins
RUN rabbitmq-plugins enable rabbitmq_management

RUN service rabbitmq-server start \
    # create new vhost 
    && rabbitmqctl add_vhost test-vhost \
    && rabbitmqctl set_permissions -p "test-vhost" "guest" ".*" ".*" ".*" \
    # create exchange and queue
    && rabbitmqadmin declare exchange --vhost=test-vhost name=test-ex type=fanout durable=true \
    && rabbitmqadmin declare queue --vhost=test-vhost name=testq-1 durable=true \
    && rabbitmqadmin declare binding --vhost=test-vhost source=test-ex destination_type=queue destination=testq-1 routing_key=route1 \
    # stop server
    && service rabbitmq-server stop

CMD rabbitmq-server start

通过

CMD

指定我的配置成功了：

FROM node:16-bullseye

# install rabbitmq
RUN apt-get update && apt-get install -y erlang rabbitmq-server

# enable default rabbitmq plugins
RUN rabbitmq-plugins enable rabbitmq_management

CMD service rabbitmq-server start \
    # create new vhost and admin user
    && rabbitmqctl add_vhost test-vhost \
    && rabbitmqctl add_user admin admin \
    && rabbitmqctl set_user_tags admin administrator \
    && rabbitmqctl set_permissions -p "test-vhost" "guest" ".*" ".*" ".*" \
    && rabbitmqctl set_permissions -p "test-vhost" "admin" ".*" ".*" ".*" \
    # create exchange and queue
    && rabbitmqadmin declare exchange --vhost=test-vhost name=test-ex type=fanout durable=true \
    && rabbitmqadmin declare queue --vhost=test-vhost name=testq-1 durable=true \
    && rabbitmqadmin declare binding --vhost=test-vhost source=test-ex destination_type=queue destination=testq-1 routing_key=route1 \
    && /bin/bash
