@dswarm/scale-scenarios v1.0.1

dSwarm scale scenarios

Install

npm install -g @dswarm/scale-scenarios

Setup

Once installed, an executable name dscale will be available, this can be used to automatically spin up a machine and set it up with all necessary dependencies.

General use:

dscale -c /path/to/config

The config file takes the format:

AWSAccessKeyId = YOUR_KEY_ID # setup in IAM
AWSSecretKey = YOUR_KEY # setup in IAM
AWSKeyPair = YOUR_KEY_PAIR #usually same name as an aws pem file
AWSSecurityGroup = allow-ssh # default
node = 10 # default
type = c5.metal # default
region = eu-central-1 # default
image = ami-009c174642dba28e4 # default

Running Scale tests

An ssh command will be output when the machine has started. Use this to log on to the machine, check the setup-status.txt file in the home directory to ensure setup has completed.

You can then cd scale-scenarios/scenarios and run any of the scenarios directly with node. You can also run npm test to run all scenarios.
