Question

当我尝试运行在Docker容器中的NodeJS服务器时，出现“拒绝连接”错误。如果我尝试从主机上卷曲服务器的URL，则会收到错误“卷曲：（56）接收失败：对等重置连接”。

运行sudo docker-compose up -d会启动我的服务，运行sudo docker ps -a会显示以下内容：

CONTAINER ID        IMAGE                COMMAND                  CREATED              STATUS              PORTS                    NAMES
e56b30b1de9c        mongo:4.1.8-xenial   "docker-entrypoint.s…"   About a minute ago   Up About a minute   27017/tcp                db
0d82b0a881e5        nodejs               "docker-entrypoint.s…"   About a minute ago   Up About a minute   0.0.0.0:3000->3000/tcp   nodejs

这些容器在IP为192.168.0.24的服务器上运行，因此我尝试通过192.168.0.24:3000/items在“ nodejs”应用中命中一个端点，但这会导致连接被拒绝错误。 / p>
