excited to share Christian’s enthusiasm for GitOps here in his first book, and we’ll continue to support him and cheer him on as he continues to share his exper- tise across the GitOps community. —Natale configuration files that are both ma- chine-readable and human-readable. The configuration files are machine-readable in a structured format (usually YAML) so that software tools can read them to automate pre-built applications. If your organization uses Helm heavily, you’re in luck! Most GitOps tools support de- ploying Helm charts. Operators Operators aren’t exactly a tool to help avoid duplicating YAML

Kubernetes Cluster eBook 16 3. Download and install kubelet, kubeadm and Docker To begin SSH into each machine and become root (for example, run sudo su -). Install the required binaries onto all three instances: joined, you will see the following in the terminal: Run kubectl get nodes on the master to see this machine join. Run kubectl get nodes on the master to display a cluster with the number of machines as you

these tools and resources that eliminate obstacles. Developers should not have to file a list of support tickets and wait forever to get what they need. It’s a good idea to have a consistent process in that build features and release code into production. Platform teams, on the other hand, exist to support application development teams and make resources available to them whenever needed. Application The platform they build is a collection of self-service APIs, tools, services, knowledge, and support. Development teams have a high degree of autonomy, but they also rely on the platform team to
