Container Communication With Docker Compose File
Step 1: Create Docker Network
- In a Docker network, containers that are interlinked may use their own containers as hosts and service call using container names as hostnames.
- Create a Docker network using the following command:
Step 2: Docker Compose
- Use Docker Compose to define the services and networks in a specifically Docker Compose YAML file. For example:
After executing This docker compose, The two containers will be in same network, as this above procedure of communication after once containers in running state can be done for this also.
How To Communicate Between Docker Containers Via “Hostname”?
In dealing with containers, Docker easily gets the place of a universal tool for both handling and development of applications. Docker containers are equivalent to isolated environments, therefore, the application of microservices architecture demands no further effort. Among the microservices principles, establishing the proper interaction between containers is a key container and Docker offers multiple tools to support communication between the containers. This article will focus on using hostnames from the host machine to facilitate communication between Docker containers. This will make it easier for users to communicate with various containers.
