Kubernetes then facilitates communication between the various nodes, and further, the various Docker containers housed within a given node. In Orka, a node is a single, physical Mac Pro within the greater cluster. Node distributed systems work in different ways, but inevitably there is the concept of a series of computational resources that are doing the work, naturally enough these are called nodes, workers, and sometimes slaves as well. Orchestration the practice of coordinating multiple computational resources for a common high-level purpose, although they may not all be doing the same work, but rather sub-portions of the same whole. Key Concepts: Containerization the practice of isolating code in a known and preservable environment, so as to ensure it will run as intended anywhere it ends up. Kubernetes is an excellent tool for managing containerized code that needs to be run in concert with other containers. Kubernetes provides a framework to run distributed systems i.e. Why Kubernetes: Kubernetes is the leading, open-source, orchestration engine for managing multiple containers, such as those that Docker provides. However, while an excellent choice for many applications, VMs are inherently complex, and thus present a greater technical debt for the average team to overcome.Ĭonversely, Docker containers are relatively simple to manage and require less overhead to run. Historically, to achieve a similar outcome, teams have used VMs (virtual machines). This means that the same code will run regardless of where it is physically because Docker provides a constant environment across machines in which to run code. It is so popular because it offers coherence between the respective development and production environments for a given project. Why Docker: Docker has emerged as the dominant containerization solution in the software world. Now, teams that focus on dev for iOS and macOS have access to this powerful tech. We understand that most native iOS and macOS developers have likely not had much exposure to these powerful tools, as they have historically not been able to run on Mac. Vote Submitted Oops Something went wrong while submitting the form. Under Preferences - Kubernetes you can disable and enable K8s. I would much rather be able to Stop Kubernetes and Uninstall Kubernetes as separate concepts.

I dont see why the installation of kube and the running state are tied together as a single concept. I want kube installed (and Im happy to have Docker be the ones to do it), but I dont necessarily need it running all the time. My comments were referring to the fact that existing installations of kubectl were broken.ĪFAICT, when we disable (Docker for Macs) kubectl, then the previously installed one is restored.
