By the end of this document, you'll have a local installation of Minikube kubernetes cluster along with all the default core components ofKubeedge deployed as services in the pods. You should be able to access JupyterHub notebooks, and the Kubeedge Dashboard.
Prerequisites
- Laptop, Desktop or a Workstation
- >= 12GB RAM
- >= 8 CPU Cores
- ~100GB or more Disk Capacity
- Optional: GPU card
- Mac OS X or Linux (Ubuntu/RedHat/CentOS)
- sudo or admin access on the local machine
- Access to an Internet connection with reasonable bandwidth
- A hypervisor such as VirtualBox, Vmware Fusion, KVM etc.
Nov 22, 2018 Kubernetes is available in Docker for Mac for 18.06 Stable or higher and includes a Kubernetes server and client, as well as integration with the Docker executable. The Kubernetes server runs locally within your Docker instance and it is similar to the Docker on Windows solution. Jan 10, 2018 Docker for Mac installation As per the official documentation, Kubernetes is only available in Docker for Mac 17.12 CE Edge. Go to the official download page and click on the Edge channel and not the Stable version. Download the.dmg file and go ahead with the standard installation steps. Tear down Kubernetes in Docker for OS X is quite an easy task. Go to Preferences, open Reset tab, and click Reset Kubernetes cluster. All object that have been created with Kubectl before that will be deleted. Click to see full answer. At the moment kubernetes server components doesn't ship any Darwin OS (MAC OS) binaries so the control plane component can't directly run under MACOS. Although they ship kubectl for Darwin OS which can use any API Server to connect to and deploy the applications.
If you already have a hypervisor on your system, you can follow the Quick Setup to do a guided Minikube setup.
Install a Hypervisor
If you do not already have a hypervisor or a virtualizer installed, install a new one. Once the hypervisor is installed, you don't need to start or use it directly. Minikube will automatically invoke the hypervisor to start the VM.
Mac OS X
Install Virtual Box or VMware Fusion.
Ubuntu
Install Virtual Box or KVM.
The KVM2 driver is intended to replace KVM driver. The KVM2 driver is maintained by the minikube team, and is built, tested and released with minikube.For installing KVM:
Then install the driver itself:
CentOS
Install Virtual Box or KVM.
For installing KVM:
Then install the driver itself:
Quick Setup
The following describes a script driven installation that you can use to deploy allthe necessary components including kubectl, minikube, kfctl along with Kubeedge itself. The script requires input from you on some configuration information and then it drives the rest of the installation. Run the following to start the installation:
Kubeedge_TAG is a tag corresponding to the version to checkout such as v0.3.0 or master.
The script asks for some config input as shown below:
Let us consider the example for CPUs configuration. When it asks Assign CPUs between 3.10 [6]: the 3.10 suggest the range of CPU cores available based on your host machine. [6] is the suggested default. You can choose any value within the range and enter the value or just press enter to accept the default value suggested in square brackets. In the image above, we choose the default 6 for CPUs and specified 12GB of memory explicitly. Note that:
- You will need to specify the virtualizer installed on the system explicitly and it needs to be one of the values provided as options.
- If you don't want to mount any local directory into the JupyterHub simply press enter instead of specifying any path.
After the configuration is complete, the script will continue execution for the next few minutes and when finished successfully should output some like:
When the installation finishes successfully, you can access JupyterHub as described in Where to go next. If you have trouble with the installation script or run into errors, you can follow the detailed installation steps manually as described below.
Install Kubectl
GCloud SDK
Mac OS X
Ubuntu
CentOS
Verify kubectl installed
Try running
This should output something like Random cards mac os.
Install & Start Minikube
Please see detailed instructions for Minikube installation.For quick setup instructions follow along below.
Mac OS X
OR
Ubuntu or CentOS
Start your minikube cluster
This takes a couple minutes as it will talk to the hypervisor and create a VM with the specified configuration.
Notes:
- These are the minimum recommended settings on the VM created by minikube for Kubeedge deployment. You are free to adjust them higher based on your host machinecapabilities and workload requirements.
- Using certain hypervisors might require you to set –vm-driver option specifying the driveryou want to use.
In case, you have the default minikube VM already created (following detailed installation instructions), please use the following to update the VM.
Installing Kubeedge using kfctl
The following steps will deploy Kubeedge components and start them on the Minikube you created above.
Download Kubeedge source
- Kubeedge_SRC is the directory where you want to download the source
- Kubeedge_TAG is a tag corresponding to the version to checkout such as
v0.3.0
Run the following to setup and deploy Kubeedge:
- KFAPP is the name of a directory to store your configs. This directory is created when you run init. Please see understanding the deployment process for more details.
The above installation may take a few minutes. At the end of the installation you should see:
Where to go next
Now you can access the Kubeedge dashboard at http://localhost:8080/ and JupyterHub at http://localhost:8080/hub/.For JupyterHub, you'll be landing on a login page.
- Use any username and password to login
- Pick an available CPU tensorflow image
- Provide at least 2 CPUs
- Provide 4Gi for the memory
- Leave 'Extra Resource Limits' alone for now
- Click Spawn.
- You should be redirected to a page that waits while the server is starting.
If the page doesn't refresh, please seetroubleshooting.
Mac Os Catalina
For further exploration refer to the guide.
So you want to install Kubernetes on your Mac? The easiest way to get going is to run Kubernetes on Docker, using Talos OS - Talos OS will install and configure Kubernetes on Docker for you. (Note that Docker Desktop does have support for Kubernetes built in, but it is an older version of Kubernetes, and limited to a single node cluster.) You can be up and exploring Kubernetes on Mac within 10 minutes, with all the advantages of an API managed, immutable, secure Kubernetes OS.
First, install Docker Desktop.
Run Docker, give it the access it asks for, and you'll see it chugging along in the menu bar. It will launch a wizard, which you can skip if you just want to run Talos and Kubernetes on your Mac.
A key component of Talos is talosctl, the CLI (Command Line Interface) which lets you interact with the OS running on your kubernetes nodes (virtual nodes in this case, but the same talosctl is used for Kubernetes on bare metal, VMWare, or cloud providers).
To get going with talosctl you need to download the latest release as shown below (or from Github here.)
Now, test if it's working by running:
Creating a local cluster is as simple as:
This command will create a simple two node cluster, with one master node and one worker node.
You can create a more complex kubernetes cluster on your Mac by passing in different parameters. Note that creating a larger cluster in Docker uses a lot of resources and takes quite a while, and is not recommended unless you have a powerful Mac. e.g. to create a cluster with 3 masters and 1 worker, use:
(Note that in order to install a new Talos OS based kubernetes cluster on the same Mac, you should talosctl cluster destroy the old cluster first, else you will run into naming conflicts. You can manually assign unique names and run multiple clusters - but it's certainly easier to just destroy the old cluster, then create a new cluster.)
The creation of the kubernetes cluster takes a while to process (a few minutes on my Macbook Pro for a two node cluster), and you can expect to see some errors, as below, where the installation system expects services to be up, but they take longer on a docker based system than expected. Note that once the services do start, the installation proceeds correctly.
As well as the command output, you can also watch the progress from the Docker dashboard (click the Docker icon in the menu bar and select Dashboard.) Click the node talos-default-master-1, and you will see the logs of the master node, and be able to watch services start:
Once the cluster create command has exited successfully, you need to set the Kubernetes configuration so it knows how to reach the API server:
talosctl config nodes 10.5.0.2
talosctl kubeconfig .
kubectl --kubeconfig kubeconfig config set-cluster talos-default --server https://127.0.0.1:6443
Mac Os Mojave
Finally, we just need to modify the talosctl config to specify which nodes you want to get information on. Talosctl can operate on one or all the nodes in the cluster - this makes cluster wide commands much easier.
talosctl config nodes 10.5.0.2 10.5.0.3
Note that these are the default node addresses for a one master, one worker cluster. If you already have a variety of containers running, or created more master or worker nodes, you can verify the node addresses using docker inspect or talosctl cluster show
You now have a complete (albeit simple) kubernetes cluster running on your mac. You can use talosctl to operate and examine the nodes. Some commands to try are:
Endless game mac os. For further options with talosctl see the getting started guide and the talosctl documentation.

There are other more flexible ways to run Kubernetes on MacOS - we'll explore a qemu based installation in a later article. But if you want to get Kubernetes on a Mac up and running quickly so you can start learning and testing - Docker and Talos OS is the way to do it.
