1# mirrord up Skill

3## Purpose
4 
5Help users create and run **multiple concurrent mirrord sessions** from one config file — think docker compose, but for mirrord — as documented in [Multiple concurrent sessions (mirrord up)](https://metalbear.com/mirrord/docs/using-mirrord/multiple-concurrent-sessions).
6 
7Useful when they need to debug **several related microservices** and manage those sessions' lifecycle together.
8 
9Each `services` entry is typically a **different** application with its own target, command, and configuration — `mirrord up` is for running several distinct applications together, not for targeting multiple pods of the *same* application. For that (label-based targeting), point users to the **mirrord-operator** or **mirrord-config** skill instead of trying to model it with `mirrord-up.yaml`.
