DEMO

Overview

The demo is required to use Terraform to bootstrap the full scenario composed by:

• 2 EC2 instances with the tag Role=web
• 2 EC2 instances with the tag Role=app
• 2 EC2 instances with the tag Role=legacy to simulate two OnPrem Virtual Machine
• 1 SSM parameter Store entry
• 3 IAM Roles
• 1 Security Group
• 1 VPC, 2 Public Subnet

Let's start

to bootstrap the scenario run the following commands

$ cd test/terraform/
$ ./run.sh apply
.....

to execute command on instances with tag:Role=web

$ ./run.sh web
+ sshless cmd -f tag:Role=web 'wget -q -O - http://169.254.169.254/latest/dynamic/instance-identity/document'
[Success] i-0681b64d16c5039b9 ip-10-0-28-176.eu-central-1.compute.internal
{
  "devpayProductCodes" : null,
  "marketplaceProductCodes" : null,
  "availabilityZone" : "eu-central-1b",
  "version" : "2017-09-30",
  "region" : "eu-central-1",

}

to execute command virtual machine OnPrem

$ ./run.sh legacy
Onprem: Query using ID (Tags not available) ID: mi-07f7cd55f45a6b585,mi-09c4a25f6c0d1eac7
+ sshless cmd -i mi-07f7cd55f45a6b585,mi-09c4a25f6c0d1eac7 hostname
[Success] mi-09c4a25f6c0d1eac7
legacy-1

[Success] mi-07f7cd55f45a6b585
legacy-2

to execute command virtual machine Azure

$ ./run.sh azure
Azure: Query using ID (Tags not available) ID: mi-0566401fcacec9264
+ sshless cmd -i mi-0566401fcacec9264 hostname
[Success] mi-0566401fcacec9264

to test the integration with Parameter Store

$ ./run.sh parameter
EC2 reading Parameter Store
+ sshless cmd -f tag:Purpose=sshless 'echo {{ssm:example.parameter}}'
[Success] i-0b17d5f281971ae1c ip-10-0-29-140.eu-central-1.compute.internal

to delete everything

$ cd test/terraform/
$ ./run.sh destroy
