docker-compose的端口号不变 [英] port number not change for docker-compose
问题描述
我已经在docker-compose中指定了端口映射,但是仍然无法正常工作,我仍然必须使用暴露中未指定的端口访问站点
I have specified port-mapping in docker-compose, but it is still not working, i still have to access site using the port no specified in expose
以下是我的docker-compose.yml
version: '2'
networks:
default:
external:
name: nat
services:
website:
build:
context: '.'
dockerfile: "./iis.dockerfile"
ports:
- 3000:8081
和相应的dockerfile
FROM microsoft/iis
RUN ["powershell.exe", "Install-WindowsFeature NET-Framework-45-ASPNET"]
RUN ["powershell.exe", "Install-WindowsFeature Web-Asp-Net45"]
ADD www/ c:\\webapp
EXPOSE 8081
RUN powershell New-Website -Name 'web-app' -Port 8081 -PhysicalPath 'c:\webapp' -ApplicationPool '.NET v4.5'
我必须使用http://192.168.105.33:8081/
来访问应用程序,如果我使用端口3000则无法使用.
I have to access app using: http://192.168.105.33:8081/
, if I do it using port 3000 it does not work.
上述配置中是否缺少任何内容?操作系统:windows server 2016
,使用具有hyper-v
和docker-compose up -d
的Windows容器来启动并运行容器...
Is there anything missing in my above configuration?? OS: windows server 2016
, using windows containers with hyper-v
and docker-compose up -d
to get containers up and running...
docker-compose inspect给我下面的输出
docker-compose inspect gives me below output
"Ports": {
"8081/tcp": [
{
"HostIp": "0.0.0.0",
"HostPort": "3000"
}
]
},
docker ps
给我下面的输出
eb7aa1e74b7f website_website "C:\\ServiceMonitor..." 14 minutes ago Up 14 minutes 0.0.0.0:3000->
8081/tcp website_website_1
8081/tcp website_website_1
dokcer-compose ps
给我下面的输出
Name Command State Ports
--------------------------------------------------------------------------------
website_website_1 C:\ServiceMonitor.exe w3svc Up 0.0.0.0:3000->8081/tcp
所以我应该能够使用端口3000在主机上访问它.
So I should be able to access it on host using port 3000.
推荐答案
也许您正在使用docker-compose run
启动容器? docker-compose run
和docker-compose up [-d] [service]
之间的端口映射有所不同,在这种情况下,端口配置为
Maybe you're launching your container with docker-compose run
? There is a difference in port mapping between docker-compose run
and docker-compose up [-d] [service]
In this case the port configuration will be ignored by design
You can use --service-ports
flag or manually expose them using -p
flag
