For example, inside the container an HTTP service might be listening on port 80. At runtime, the port might be bound to 42800 on the host. To find the mapping between the host ports and the exposed ports, use the docker port command....
映射端口(port mapping):使用-p参数可以将容器内部的端口映射到主机上的端口。例如,-p 8080:80将容器内的 80 端口映射到主机的 8080 端口,这样你就可以通过访问主机的 8080 端口来访问容器的服务。 数据卷(volume):数据卷是用于持久存储数据的特殊目录或文件。数据卷可以在容器之间共享和重用,使得数据持久化且不...
Alternatively, manual port mapping can be specified with the--publishor-poptions, just as when using docker run: $docker compose run --publish 8080:80 -p 2022:22 -p 127.0.0.1:2021:21 web python manage.py shell If you start a service configured with links, the run command first checks ...
这样您就可以在宿主机上通过 localhost:8080 或者容器的 IP 地址 容器IP:8080 访问服务。
DockerContainer- containerPort- hostPort+mapPort()PortMapping 总结 在使用Docker容器时,我们经常会需要配置两个端口来实现端口映射,一个用于外部通信,一个用于内部管理或通信。通过合理配置端口映射,我们可以更灵活地实现容器与外部世界的通信,提高应用程序的可用性和安全性。希望本文对大家有所帮助,谢谢阅读!
docker run –security-opt label:disable -i -t fedora bash 如果你需要在container内执行更为严格的安全策略,那么你可以为这个container指定一个策略替代。比如你可以使用下面的命令来指定container只允许监听apache port docker run –security-opt label:type:svirt_apache_t -i -t centos bash ...
Use docker port(1) to see the actual mapping, e.g. docker port CONTAINER $CONTAINERPORT. --pid="" Set the PID mode for the container Default is to create a private PID namespace for the container 'container:<name|id>': join another container's PID namespace 'host': use the host'...
