AWS EC2 (Consul clients) deployment.

After deploying the Infra and Consul servers is time for Consul clients.

• | To spin up the client agents we use Terraform Local Backend - we just reference the data.

Go to the consul_client_dc1 or/and consul_client_dc2 setup a needed count for the clients in main.tf

terraform init
terraform apply 

To test you will need Kitchen and Selenium:

• Kitchen provides a test harness to execute infrastructure code on one or more platforms in isolation.
• Install kitchen.ci
• Install selenium and all its dependencies on Mac with brew

$ brew install selenium-server-standalone
$ brew cask install java

# GeckoDriver for firefox
$ brew install geckodriver 

# Chromedriver for chrome
$ brew cask install chromedriver 

If you use rbenv set local to 2.6.0

$ rbenv local 2.6.0

Than simply execute a following commands:

bundle exec kitchen converge
bundle exec kitchen verify
bundle exec kitchen destroy
