1. Instantiate the template files

Fill in the required values in the template variable file

Copy the file cluster/tpl-vars-blank.txt to cluster/tpl-vars.txt and fill in all the required values in tpl-vars.txt. These include things like your AWS keys, your GitHub signon, and other identifying information. See the comments in that file for details. Note that you will need to have installed Gatling (https://gatling.io/open-source/start-testing/) first, because you will be entering its path in tpl-vars.txt.

Instantiate the templates

Once you have filled in all the details, run

$ make -f k8s-tpl.mak templates

This will check that all the programs you will need have been installed and are in the search path. If any program is missing, install it before proceeding.

The script will then generate makefiles personalized to the data that you entered in clusters/tpl-vars.txt.

Note: This is the only time you will call k8s-tpl.mak directly. This creates all the non-templated files, such as k8s.mak. You will use the non-templated makefiles in all the remaining steps.

2. Ensure AWS DynamoDB is accessible/running

Regardless of where your cluster will run, it uses AWS DynamoDB for its backend database. Check that you have the necessary tables installed by running

$ aws dynamodb list-tables

The resulting output should include tables User, Music and Playlist.

3. Build and push the Images

$ make -f magic.mak docker_images

Once pushed, make these images public manually.

4. Start the cluster

This can take a long time since it'll create the cluster.

$ make -f magic.mak deploy_all

5. Delete the cluster

$ make -f magic.mak teardown

6. Load testing with gatling

To test the performance of our application when under heavy load, run:

$ ./gatling-<service>.sh <number_of_requests_per_run> <delay_between_each_run>

We are having all and playlist as two options for here.

For example, running:

./gatling-playlist.sh 200 100

generates 200 requests every 100 ms for the playlist service. We can view the result of gatling runs in Grafana dashboard with respecting link.

To kill the gatling jobs, run

./tools/kill-gatling.sh
