Orchestrating Rocket Simulations W/ Argo
summary
Astra replaces a 40+ step manual simulation process with an API-driven platform that uses Argo Workflows and Hera to submit containerized workflow images tied to specific git refs, enabling exact reruns of past tests. A FastAPI + Postgres queue with resource locking schedules runs against scarce simulator hardware, Hera-generated containers (about 2.5k lines of Hera code) produce the YAML and submit workflows, logs archive to object storage and the system increases observability and repeatability.
