over and over again with identical results. For instance, a command that updates a field in a database to a fixed value can be issued multiple times safely. Doing so might be wasteful, but the result suppose the commands try to update a local database on a system where a schema change had occurred, or after an administrator had deleted the whole database. In those scenarios, the command will fail deleting the whole virtual system and creating a new container. So in the example of updating a database in the previous section, Kubernetes heals the system simply by starting a new set of containers

Containers Built for container apps and runs on Kubernetes Serverless Runs serverless with no CI/CD engine to manage and maintain DevOps GENERAL DISTRIBUTION Why Cloud-Native CI/CD? 18 Traditional CI/CD for Containers and Kubernetes Require IT Ops for CI engine maintenance Pipeline as a service with no Ops overhead Plugins shared across CI engine Pipelines fully isolated from each other Plugin dependencies Kubernetes resources Admin manages persistence Platform manages persistence Config baked into CI engine container Configured via Kubernetes ConfigMaps OPENSHIFT PIPELINES GENERAL DISTRIBUTION 19 OpenShift

well, such as minikube, or you can use one of the public cloud providers like Google Kubernetes Engine or Amazon’s EKS. You’ll need to create a new repository for this tutorial and make it available

evolved further by incorporating microservices-based architectures and even databases in the form of database DevOps. Now there’s a new kind of Ops. GitOps is rapidly gaining popularity to extend the scope
