我有一个Node.js应用程序，它是容器化的，部署在AKS上。
我还将RabbitMQ部署在同一集群上，queuename.rabbitmq.svc.cluster.local:5672上可用
当它用一个普通的Dockerfile容器化时，它工作得很好，像这样：

# Install Node.js
FROM node:20.2.0-alpine3.16

# stage 1 for dev
RUN mkdir -p /usr/src/app

RUN mkdir -p /usr/src/app/dist
WORKDIR /usr/src/app
COPY . /usr/src/app

RUN npm install

EXPOSE 80
ENTRYPOINT [ "npm", "start" ]

字符串
但是当我用一个非root用户和一个不同的端口优化它时，它无法连接到RabbitMQ并抛出这个错误：

/* 7 */
{
    "_id" : ObjectId("647db632e239b362ce8649ac"),
    "serviceName" : "nodejs-service",
    "controllerName" : "RabbitMQService",
    "methodName" : "connectToRabbitMQ",
    "message" : "Failed to connect to RabbitMQ.",
    "exception" : "Error: Expected amqp: or amqps: as the protocol; got \n    at connect (D:\\LyveCloud-11-04-23\\nodejs-service\\node_modules\\amqplib\\lib\\connect.js:171:11)\n
    "logLevel" : "Error",
    "severity" : "Critical",
    "request" : null,
    "response" : null,
    "statusCode" : "400",

除了Dockerfile中的更改外，没有任何更改，如下所示：

# Install Node.js
FROM node:20.2.0-alpine3.16

# stage 1 for dev
RUN mkdir -p /usr/src/app

RUN mkdir -p /usr/src/app/dist
WORKDIR /usr/src/app
COPY . /usr/src/app

RUN npm install

# Create a non-root user and group
RUN addgroup -S appgroup && adduser -S appuser -u 1001 -G appgroup
# Set ownership of necessary directories
RUN chown -R appuser:appgroup /usr/src/app
# Set user and group for the container
USER appuser:appgroup
EXPOSE 8080
ENTRYPOINT [ "npm", "start" ]

这可能是什么原因，我该如何解决它？
