Tutorials

Each tutorial builds something bounded and ends with a runnable state. They assume you completed the quickstart and have a server on http://localhost:8080. Read them in order; each one may assume the one before it and never the one after.

• Build your first service makes the quickstart’s four administration calls one at a time, shows the CLI form of each, and explains what every response means.
• Add your first connector connects Orion to PostgreSQL and builds a service that writes an order and reads the customer’s history back, without storing a password.
• Build an orders API end to end takes one service from source files to a safe update: validation, a restricted connector, offline tests, deployment, traces and failure handling.
• Test and promote a service proves a workflow offline with lint, dry run and regression cases, then ships it to a second instance as one versioned package.
• Run the example packages deploys the repository’s ready-made services, from a threshold check to Kafka ingress and a model-backed tournament.
