Usage

The Instrument Service application can be run as follows to rely on Testcontainers to spin up a PostgreSQL database:

./gradlew bootTestRun

You can directly call the Instrument Service on behalf of a tenant (dukes or beans), for example, using httpie.

# Get instruments
http :8181/instruments X-TenantId:dukes

curl --location 'http://localhost:8181/instruments' \
--header 'Content-Type: application/json' \
--header 'X-TenantId: dukes'

# Add instrument
http :8181/instruments X-TenantId:dukes name="Pearl" type="drums"

curl --location 'http://localhost:8181/instruments' \
--header 'Content-Type: application/json' \
--header 'X-TenantId: dukes' \
--data '{
  "name": "Pearl", 
  "type": "drums" 
}'

The Edge Service application can be run as follows:

./gradlew bootRun

Two tenants are configured: dukes and beans. Ensure you add the following configuration to your hosts file to resolve tenants from DNS names.

127.0.0.1       dukes.rock
127.0.0.1       beans.rock

Now open the browser window and navigate to http://dukes.rock/instruments/. The result will be the list of instruments from the Dukes rock band.

Now open another browser window and navigate to http://beans.rock/instruments/. The result will be the list of instruments from the Beans rock band.
