英文:
Dockerfile expose 80 port
问题
我正在尝试创建一个带有go mod和1.18的简单Docker容器。
我的应用程序在8080端口运行，但我想在80端口运行。
Dockerfile
FROM golang:1.18
WORKDIR /usr/src/app
# 预先复制/缓存go.mod以预先下载依赖项，并仅在后续构建中重新下载更改的依赖项
COPY go.mod go.sum ./
RUN go mod download && go mod verify
COPY . .
RUN go build -o server
CMD ["./server"]
然后我运行docker build:
docker build -t go-k8s .
然后运行docker run:
docker run --rm -p 8080:8080 go-k8s:latest
但是什么都没有发生 
英文:
I am trying to create a simple docker container with go mod and 1.18.
my app runs in 8080 port but i wanna run in :80 port
Dockerfile
FROM golang:1.18
WORKDIR /usr/src/app
# pre-copy/cache go.mod for pre-downloading dependencies and only redownloading them in subsequent builds if they change
COPY go.mod go.sum ./
RUN go mod download && go mod verify
COPY . .
RUN go build -o server
CMD [ "./server" ]
so i run docker build:
docker build -t go-k8s .
and docker run
docker run --rm -p 8080:8080 go-k8s:latest
And nothing happens

得分: 1
如larsks所说，您需要使用80:8080语法将外部端口80绑定到内部端口8080。
另外要考虑的是确保您的应用程序在开发环境中监听所有接口。
这个问题似乎至少与您的问题有些关联。
英文:
As larsks says, you need to bind from the external port 80 to the internal port 8080 using the 80:8080 syntax.
Something else to consider is making sure that your app is listening on all interfaces in your development environment.
This question seems at least vaguely related to yours
