The Docker client defaults to connecting to unix:///var/run/docker.sock on Linux, and tcp://127.0.0.1:2376 on Windows. -H accepts host and port assignment in the following format: tcp://[host]:[port][path] or unix://path For example:...
Fixed a permission denied error when binding a privileged port to a non-localhost IP on macOS. Fixes docker/for-mac#697. Fixed a resource leak introduced in 4.23. Related to docker/for-mac#6953. For Windows Fixed a bug where a "Docker Desktop service not running" popup appeared when servi...

Small other note: In another container, with Wildfly, I have the exact same problem, I expose 9990 and -p 9990:9990 to reach the application management console. And can verify inside the container that it is available, but cannot reach it on localhost:9990 in my browser. terpz(Martin Ter...
EXPOSE 8080 ARG BUILD=undetermined ENV BUILD=$BUILD CMD ["npm", "run", "start"] If I inspect the container withdocker inspect accountI can clearly see that the ports are all mapped correctly. "PortBindings": {"8080/tcp": [{ "HostIp": "", "HostPort": "8084". }]} ...
以前就好奇docker run时的port公开方式-p 8080:8080和--expose(或者Dockerfile里的EXPOSE)的区别, 当时相信了stackoverflow上高手的回答Difference between "expose" and "publish" in docker - Stack Overflow,提到 如果什么都不指定,那么除了该容器自己,谁都不能访问那个port。
EXPOSE 8080 CMD ["node", "app.js"] 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 接着,构建Docker镜像并运行容器: docker build -t mynodeapp . docker run -d -p 8080:8080 mynodeapp 1. 2. 现在,我们可以在浏览器中访问http://localhost:8080查看Node.js应用程序的输...

EXPOSE <port>/<protocol> 我们不必指定协议,因为 Docker 可以使用默认的 TCP 协议。但是,我们可以提供其他协议,例如 UDP 协议。 Docker 将使用默认的 TCP 协议,因为 Nginx 官方 docker 文件中没有指定该协议。 COPY docker-entrypoint.sh /COPY 10-listen-on-ipv6-by-default.sh /docker-entrypoint.dCOPY 20-...
EXPOSE(指定容器需要映射到宿主机器的端口) 作用: EXPOSE指令是声明运行时容器提供的服务端口,也只是一个声明,在容器运行时并不会因为这个声明应用就一定会开启这个端口的服务,容器启动时,还是需要通过 -p host-port:container-port来实现映射。 EXPOSE主要是帮助镜像使用者了解这个镜像服务的监听端口,以方便进行映射配...
