# check.ps1 - a local pre-push check for the ClinicApi sample.
# Run it from the folder that holds compose.yaml:   .\check.ps1
# It builds the image, starts the api and its database, waits for /health,
# reads /patients, prints PASS or FAIL, and always takes the stack down again.
# It asks Compose which host port the api service publishes for container
# port 8080, so it works whatever port your compose.yaml uses.
# Works in Windows PowerShell 5.1 and PowerShell 7.
