DevOpsDays Kraków 2022 - Building labs using component-based architecture with Terraform and Ansible

This presentation has the purpose to share an approach using component-based architecture with infra as a code, thus helping the develop teams to be more productive and have reliable environment labs for developing and testing.

1. Building labs using component-based architecture with terraform and ansible Ederson Brilhante
2. Brazilian expat SRE at Splunk 14 years of experience in IT About Me
3. Splunk
4. GDI and Splunk Technical Add-ons
5. Splunk Technical Add-ons New TA version Delivery Build new dev lab Build QA lab Coding Development TA Cycle
6. Lab Automation
7. First propose: Infra as a code in each TA repo
8. Benefits • Terraform and Ansible for deployment and provisioning • Reduce the pain to create labs • Avoid duplicate or rework • Reliable and Consistent Labs across dev cycles
9. Drawbacks • Copy and Paste in some common configuration • Scale to more TA demands time • Customization demands to know IaC
10. Second propose: Splunk Attack Range
11. • Allow use IaC to build lab • Already support some use cases Benefits
12. Drawbacks • Static configuration • Sequential deployment • No support for modular configuration
13. Third propose: Component-based approach
14. Requirements • Deploy infra with IaC under the hood • Allow customized and parallels Labs • User don't need to write IaC scripts to use supported OS distros and configs • Manage the lab lifecycle
15. Lab Builder
16. User Lab Builder Framework

18. config = { <lab1> <labN> } "lab1" = { "type" = "<type_environment>" "nodes" = { <node1>, <nodeN> } } User Input File = input.tfvars
