voltest

Overview ¶

voltest — HTTP server that persists messages to a mounted volume.

Endpoints:

POST /write?msg=hello   append a message to /data/log.txt
GET  /                  list all messages written so far
DELETE /reset           clear the log

Mount a volume at /data to verify persistence across VM restarts:

jerboa volume create testdata
jerboa build ./voltest --name voltest
jerboa run voltest:latest -v testdata:/data -p 8080:8080 --name v1
curl -X POST "http://localhost:8080/write?msg=hello"
curl -X POST "http://localhost:8080/write?msg=world"
curl http://localhost:8080/
jerboa stop v1 && jerboa rm v1
jerboa run voltest:latest -v testdata:/data -p 8080:8080 --name v2
curl http://localhost:8080/   ← still shows "hello" and "world"
