推荐答案

在运行docker时，您可以指定外界希望访问哪些端口.基本语法是:

When running docker, you can specify which port(s) you'd like to be accessible to the outside world. Basic syntax is:

docker run -p hostPort:containerPort imageName

或者只是

docker run -p hostPort imageName

在第一种情况下，将在外部使用hostPort，但在容器内部:将使用containerPort.在第二种情况下，您将只在容器的内部和外部使用该端口.

In the first case, externally, hostPort will be used, but inside the container: containerPort will be used. In the second instance, you'd just be using that port both inside and outside your container.

您还可以使用 EXPOSE 创建带有暴露端口的映像. Dockerfile中的a>命令.

You can also create an image with ports exposed by using the EXPOSE command in a Dockerfile.
