Now that Docker for Mac uses localhost instead of an IP, should communication between docker containers and non-docker containers be possible using localhost for all? Amazon music mac os app. I have docker services and non-docker services running and I need them to read from a DB in docker, but I keep getting this when calling the container for dynamodb-local.

Docker Compose is a tool used to define and run multi-container Docker applications. Users utilize this software to launch, execute, communicate, and close containers with a single coordinated command. This tutorial will show you how to install Docker Compose on CentOS 7. Docker Engine is the industry’s de facto container runtime that runs on various Linux (CentOS, Debian, Fedora, Oracle Linux, RHEL, SUSE, and Ubuntu) and Windows Server operating systems. Docker creates simple tooling and a universal packaging approach that bundles up all application dependencies inside a container which is then run on Docker.

• CentOS Docker 安装 Docker 支持以下的 64 位 CentOS 版本： CentOS 7 CentOS 8 更高版本. 使用官方安装脚本自动安装 安装命令如下： curl -fsSL bash -s docker -mirror Aliyun 也可以使用国内 daocloud 一键安装命令： curl -sSL https://get.daoclou.
• I have docker installed on CentOS 7 and I am running firewallD. From inside my container, going to the host (default 172.17.42.1) With firewall on container# nc -v 172.17.42.1 4243 nc: connect.

Docker From Centos 7.6

From the docker-compose networking doc (https://docs.docker.com/compose/networking/) it looks like all of the containers should be set up on a shared network to talk to each other. I can reach the running services from a browser with http://localhost:port, but not the dynamo-local container. I’m trying to figure out if I have a dynamo issue, or a docker networking issue.
My questions are

Docker From Centos Example

1. Cross-container networking: Can the containers call each other by localhost:port (localhost:8000 for example) or can they only use the compose name like dynamodb:8000?
2. Cross-system networking: Can the non-docker services running locally use the db at localhost:8000?
