Talk will be about?

Baremetal

Container deployment

Won't cover

Project

Deployment workflow

Feature branches

Moment of truth

feature/Jira-5678

master

Bad scenario

feature/Jira-5677

feature/Jira-5679

master

feature/Jira-5680

Good scenario

Run all the tests

feature/Jira-5677

Jenkins pipeline

Results

feature envs

push to feature branch

tests

GGR

Selenoids

Merge/delete feature env

Pain points

  • Browser cluster monitoring
  • Windows Powershell DSC
  • Windows Server 2016 1709

Lessons learned

  • Keep your infrastructure as a code
  • Always test what your deployment
  • Run all your test for merge request
  • Collaborate with your team
  • Ensure high availability
