Without Varnish

• Create docker build

➜  varnish-demo git:(master)   cd application
➜  application git:(master)    docker build -t application .

• Run the application you built.

➜  application git:(master)    docker run -e "SPRING_PROFILES_ACTIVE=dev" -p 8080:8080 -t application

• The application is ready. (http://localhost:8080/)

• Page test OK

With Varnish

• Create docker build and run application

➜  varnish-demo git:(master) docker-compose up --build 

• The application is ready. (http://localhost:8000/)

Load Test with Apache Benchmark

• Let's put both apps into load test

Without Varnish: at port 8080, with Varnish: at port 8000
