Frequently Asked Questions

How can i keep my data docker compose environment up to date?

The data-docker-compose repository uses git submodules that point to develop branches of various repositories. To keep the environment updated, you need to:

1. git pull (to update the data-docker-compose repo)
2. git submodule update --remote (to update the submodules)

How does networking work?

Networking between applications varies depending on whether they are running inside docker or outside, and what they're calling.

• From Docker to Docker: Services running in Docker can call each other using their service names as DNS (e.g., http://service-name:8081).
• From Native to Docker: Native microservices running in your IDE or from your CLI can call Dockerized services using http://localhost:<exposed-port>.
• From Docker to Native: Dockerized services can call native services running on the host using:
  • Linux: http://<host-ip>:<native-service-port>
  • MacOS/Windows: http://host.docker.internal:<native-service-port>
