Why localhost Doesn’t Work Between Docker Containers (And How to Fix It)

1. 1Run Docker containers with host networking using the --net=host flag to enable localhost communication
2. 2Configure Docker Compose to use a custom network for inter-container communication
3. 3Use the Docker container's IP address or a service discovery mechanism instead of localhost
4. 4Apply the --add-host flag to add a custom host entry for inter-container communication
5. 5Test the communication between containers using a tool like curl or nc

DevOps teams and developers working with Docker containers will benefit from understanding this networking issue to ensure smooth communication between services

💡 localhost is relative to each container's own network stack, so it doesn't work for inter-container communication
