GitOps a new fish?

4. It was in the lake..!
● You were using it before it came to trending.
● DevOps practices + IaaC(Infra as a code) = GitOps
● DevOps Practices like Continuous building and Continuous
deploying.
● IaaC tasks like
○ Terraform for infrastructure provisioning
○ Ansible playbooks for defining configurations
○ Kubectl for container orchestration using mainfest

● Two kind of deployment strategy : Push and Pull based
● Push: When someone push changes to the repo, it invokes the pipeline and pushes the
changes to the Infrastructure
● Pull: We instruct the infrastructure to actively look up for the changes made to the repo, after
it find out changes made to the repo it pulls the changes and apply it internally.
