Load testing a node decision service
Use this repo to run Simone's Nodejs Decision Service as a set of independently scalable services, collectively known as a "fullstack service".
Running the service locally
Start by building each service:
make build-datafile
make build-decision
Then run both services, starting with the datafile service:
make run-datafile
make run-decision
To verify that things are running correctly, try testing the decision service:
make test-decision
Running the service locally in separate docker containers
Start by building each service:
make docker-build-datafile
make docker-build-decision
Then run both services, starting with the datafile service:
make docker-run-datafile
make docker-run-decision
At this point, both services should be running on their default localhost ports. To verify that things are running correctly, try testing the decision service:
make test-decision
Load testing the service locally in a docker swarm
Start by initializing a Docker swarm:
make start-swarm
Then build your docker containers:
make docker-build-containers
Now deploy your stack using the appropriate deploy configuration:
make DEPLOY_CONFIG="loadtest_fullstack_service_on_local" docker-deploy-stack
Your terminal should display the running output of the load test.
When you're done, remove your stack with this command
make DEPLOY_CONFIG="loadtest_fullstack_service_on_local" docker-stop-stack
Load testing the service on AWS in a docker swarm (not working)
Start by opening an ssh connection to the cluster manager:
make aws-ssh
Once you've successfully opened it, close the ssh connection and open up an SSH tunnel for docker:
make aws-tunnel
This command will display another command which you'll need to run to open the tunnel.
Now, again on your local machine, enter the following command to build your docker containers remotely:
make aws-build-containers
Now you can launch your stack on the cluster:
make DEPLOY_CONFIG="loadtest_fullstack_service_on_local" aws-deploy-stack
You'll need to user cloudwatch to monitor the output of the loadtest service replicas.
When you're done, remove your stack with this command
make DEPLOY_CONFIG="loadtest_fullstack_service_on_local" aws-stop-stack
Load testing an externally-hosted decision service from a locally-hosted container
Repeat the steps in "Load testing the service locally in a docker swarm", using
make DEPLOY_CONFIG="loadtest_cloudfront_from_local" docker-deploy-stack
Load testing an externally-hosted decision service from a locally-hosted container
This also doesn't work yet. Repeat the steps in "Load testing the service on AWS in a docker swarm", using
make DEPLOY_CONFIG="loadtest_cloudfront_from_aws" docker-deploy-stack
