Sample APIS

1. API to get JWT Auth Token
curl --location --request POST 'dev-sandbox/api/v1/auth/token' \
--header 'Content-Type: application/json' \
--data-raw '{
    "userName": "[email protected]",
    "password": "admin01@123#"
}'
2. API to get all customers (paginated)
curl --location --request GET 'dev-sandbox/api/v1/customer/?pageNum=0&pageSize=10' \
--header 'Authorization: Bearer <<REPLACE JWT TOKEN HERE>>'

In above code, replace the text <<REPLACE JWT TOKEN HERE>> with JWT token from Auth API

Troubleshooting

  • If after running Docker Compose, you are getting 404 on the APIs,
    • Restart ONLY the load-balancer container - sometimes this happens when loadbalancer starts before application server starts
    • Create an alias for localhost (127.0.0.1)
      • The reason for doing this is because we have configured the traefik loadbalancer using hostname dev-sandbox
      • So if you hit any api with host as localhost, it wont work with current configuration of traefik loadbalancer
      • Just open the following file /etc/hosts, and add following line at the end
        127.0.0.1 dev-sandbox
      • After this configuration, restart the application using
        docker-compose restart

To-Do

  • Add a wait-for script in Docker compose for following container dependencies
    • Loadbalancer - Depends on - Application
    • Application - Depends on - Database
