System API

System API is used as interface between TDX services and the operator.

It currently does the following things:

• Event log: Services inside a TDX instance can record events they want exposed to the operator used to record and query events. Useful to record service startup/shutdown, errors, progress updates, hashes, etc.

Future features:

• Operator can set a password for http-basic-auth (persisted, for all future requests)
• Operator-provided configuration (i.e. config values, secrets, etc.)
• Restart of services / execution of scripts

Event log

Events can be added via local named pipe (i.e. file pipe.fifo) or through HTTP API:

# Start the server
$ go run cmd/system-api/main.go

# Add events
$ echo "hello world" > pipe.fifo
$ curl localhost:3535/api/v1/new_event?message=this+is+a+test

# Query events (plain text or JSON is supported)
$ curl -s localhost:3535/api/v1/events?format=text
2024-10-23T12:04:01Z     hello world
2024-10-23T12:04:07Z     this is a test
