getting started

• activate rest server on docker
• to build the jfx app in JavaFx project :

mvn jfx:jar ; sudo java -jar target/jfx/app/org.kevoree.docker.containerdriver-jfx.jar

• to start the rest server, in the rest project

sudo mvn exec:java

• start a container :

 sudo docker run --cap-add=NET_ADMIN -ti --cpuset=0 ahervieu/stress_diverse

Use refresh button to update container list !

##Playing with Rest API

GET Request
http://localhost:8081/container_manager_rest_server/rest/api/containers
http://localhost:8081/container_manager_rest_server/rest/api/ID of the container
PUT request   @Consumes(MediaType.APPLICATION_JSON)
http://localhost:8081/container_manager_rest_server/rest/api/ID of the container

How to test it :

Testing CPU :

in the container :

stress --cpu 2

Open system monitor on your host, then change values of numbers of cpu and frequency in the application and observe the load balancing. You can put -1 value to remove frequency limitations

Testing memory :

In the UI set a Max memory at 250m (=250Mo) in the container :

stress--vm 2 --vm-bytes 250M

Docker container will try to consume 2*250Mo of memory. You can observe the limitation at 250 in the resource monitor. Then put -1 and ovserve that the container then consumes 500 Mo.

Testing Network :

In the container :

 time(wget http://www.obeo.fr/download/release/designer/6.2/latest/juno3/bundles/ObeoDesigner-6.2-linux.gtk.x86_64.zip)

Then add traffic limitation and observe variations.

Testing IO :

In the container :

 time $(dd if=/dev/zero of=testfile0 bs=1000 count=100000 && sync)
