Summary
This chapter has covered continuous deployment and delivery, and we understood the need for CD and the basic CD workflow for a container application. We discussed several modern deployment strategies and how CI tools cannot fulfill those responsibilities. Using the GitOps principles, we created an Environment repository and deployed our GKE-based environment using GitHub Actions by employing the push-based model. Then, we looked at using Argo CD as our CD tool and installed it. To avoid committing sensitive information in Git, such as secrets, we discussed Bitnami’s Sealed Secrets. We then deployed the sample Blog App using Argo CD, using GitOps all the while.
In the next chapter, we will explore another vital aspect of modern DevOps – securing the deployment pipeline.
