Significant productivity gains were created by decoupling the lifecycle of the underlying machine from applications (in VMs), as well as the life cycles of applications from each other. This allowed the aforementioned web server admin the superuser rights needed to administer the web server, without granting access to either the host machine or to services running on other VMs. One key benefit was that an application could now be ring fenced off into a different administrative/security domain. This was enabled primarily through the usage of a hypervisor. VMs allowed an entirely separate OS to be installed on top of an existing machine and OS. Sometime around the mid 2000s, virtual machines for production services became increasingly interesting (perhaps because of hardware support in AMD and Intel CPUs). It is easiest to understand the term bare metal in the context of Virtual Machines (VMs). What is bare metal? A trip down memory lane - virtual machines This section introduces and examines these components. Some of the overlaps and touch-points between bare metal and Kubernetes introduce significant complexities in order to combine the two technologies, even though it might seem easy at first. The whole picture is easily understandable by first examining both terms separately. Those technologies center around providing cloud-like semantics and interfaces for bare metal management and provisioning (for example, MAAS – Metal as a Service), container management and orchestration (provided by Kubernetes), and hybrid cloud technologies allowing for coherent management of on- and off-premises servers (such as Juju).īut what exactly is bare metal Kubernetes? Bare metal Kubernetes explainedĪs the name implies, two key technologies comprise bare metal Kubernetes. If you have already configured other Kubernetes clusters, you should merge the output from the microk8s config with the existing config (copy the output, omitting the first two lines, and paste it onto the end of the existing config using a text editor).A typical server aka bare metal Image credit: metal Kubernetes has grown in popularity primarily due to the maturation of several key technologies. Running the following command will output the kubeconfig file from MicroK8s: microk8s config

To install the macOS version of kubectl, see the official documentation. There are some advantages to running the native version of kubectl for macOS, notably when working with files (which otherwise need to be copied to/from the VM). If you have already configured other Kubernetes clusters, you should merge the output from the microk8s config with the existing config (copy the output, omitting the first two lines, and paste it onto the end of the existing config using a text editor). If you have not already configured kubectl on the host for other clusters, you can open a ‘cmd’ Command Prompt and run the following: cd %USERPROFILE%

#What is kubernetes context windows

To install the Windows version of kubectl, see the official documentation. There are some advantages to running the Windows native version of kubectl, notably when working with files(which otherwise need to be copied to/from the VM).

MicroK8s comes with its own kubectl command, which can be accessed like this: microk8s kubectl If you have not already configured kubectl on the host, you can just open a terminal and generate the required config : cd $HOME If you’d prefer to use your host’s kubectl command, running the following command will output the kubeconfig file from MicroK8s. If you are using or want to use a different kubectl command, see the relevant sections below for your OS Linux It is run in a terminal like this: microk8s kubectl By default, this is accessed through MicroK8s, to avoid interfering with any version which may already be on the host machine (including its configuration). MicroK8s comes with its own packaged version of the kubectl command for operating Kubernetes.
