docker - 一个container下面可否映射多个端口到Host

Question

Docker下在一个container下面可否映射多个端口到Host

Answer 1

Of course it is possible, buddy, you can read the document carefully. There are instructions in the document. If the option format of a parameter is [], such as
-H=[]host
-p=[]portdirection
This means that this flag can appear multiple times, so the port mapping rule can be specified multiple times here.

In addition, this can be implemented using EXPOSE in the Dockerfile. Of course, it can also be specified multiple times.

Answer 2

Yes, for example: docker run -d -p 80:80 -p 22:22
Map 80 and 22 to host respectively
