This 4-day hands-on oriented course is designed to provide participants with the theory and know-how to automate application delivery using GitOps principles. Through real-world scenarios workshops, attendees will master deploying robust CI/CD workflows based on Gitflow practices with containers, Kubernetes, targeted environment, rollouts and continuous deployment operators. By the end of the course, participants will be able to confidently build, deploy, and operate GitOps-driven application pipelines in cloud-native environment.

Key Takeaways

Learn how GitOps enable operational consistency and predictability. Learn how to use Git as the single source of truth to manage infrastructure and application configurations for predictable, auditable, and automated deployment workflows.
Create robust CI/CD pipelines for Gitflow workflows. Gain hands-on experience implementing Gitflow-oriented CI/CD pipeline to trigger different pipeline stages based on branch type to build, test and deploy to specific environments.
Implement progressive application delivery strategies to reduce risk, increase flexibility and provide faster feedback. Learn to use deployment strategies like blue/green and canary to minimise risk and to ensure controlled deployments of new features.
Eliminate application and configuration drifts with GitOps practices. Master the use of GitOps continuous delivery tool like Argo CD to deploy and reconcile applications declaratively.
