wait-for-service.sh helps streamline the issue of service dependencies in microservices and containerized applications by ensuring dependent services are fully operational before launching a service.
The wait-for-service.sh script detects when a service is reachable at a specified port and waits until it is ready to handle requests, preventing race conditions during container startup.
Using wait-for-service.sh in Docker Compose involves setting up the script, creating a docker-compose.yml file with service dependencies, running the services, and checking logs to ensure proper functionality.
This tool is valuable as it prevents race conditions, enhances startup reliability by avoiding failures due to unavailable dependencies, and is simple to integrate into existing Docker Compose setups.
