The Docker daemon pulled the "hello-world" image from the Docker Hub.ģ. The Docker client contacted the Docker daemon.Ģ. To generate this message, Docker took the following steps:ġ. This message shows that your installation appears to be working correctly. Status: Downloaded newer image for hello-world:latest If Docker was installed successfully, the output would look like: Unable to find image 'hello-world:latest' locallyĭigest: sha256:f2266cbfc127c960fd30e76b7c792dc23b588c0db76233517e1891a4e357d519 STEP D8 - Verify the engine is installed correctly: $ docker run hello-world STEP D7 - Logout of your SSH session and log back in for the changes to take effect. STEP D6 - Add your login to the Docker group: $ sudo usermod -aG docker $USER

$ sudo apt-get install -y docker-ce docker-ce-cli containerd.io

STEP D5 - Install the Docker engine: $ sudo apt-get update STEP D4 - Add the Docker repository: $ sudo add-apt-repository \ STEP D3 - Add Docker’s GPG key: $ curl -fsSL | sudo apt-key add. STEP D2 - Install packages that allow APT to use HTTPS: $ sudo apt-get update STEP D1 - Remove old versions of Docker if they’ve previously been installed: $ sudo apt-get remove docker docker-engine docker.io containerd runc In contrast, a virtual machine (VM) has both the OS and applications on shared hardware.

In order to use KinD, we need to install Docker first.ĭocker is an open-source platform that allows developers to easily package/deploy/run software applications in self-contained packages called containers which can run anywhere.ĭocker containers provide another level of abstraction in that the containers share the operating system. This will allow you to allocate 4 vCPUs and 8GB of RAM to Docker. KinD can be installed on machines with minimal hardware configuration but for the purposes of running K8ssandra, the minimum specs required are: In this post, we will be providing the steps for creating a KinD cluster on Ubuntu Focal 20.04. It requires Docker to be installed and configured. The kind tool lets you run Kubernetes on your laptop or PC. Once you have a Kubernetes cluster running, you will be able to deploy K8ssandra locally. The participants must copy their configuration file to their local computer.If you’re new to Kubernetes and don’t know where to start, follow the steps below to install and configure a Kubernetes cluster with KinD on an Ubuntu machine. If you are an instructor, send the generated configuration files to each You will need this file later in the tutorial. If your cluster is named differently, replace all references with the name of your cluster. This command assumes your cluster is named tutorial-cluster. Generate a Kubernetes configuration file for each participant: The kubectl command uses the configuration file to operate on the cluster. The cluster details, the service account, the credentials and the namespace of the participant. "", "", ""]Įach participant needs to use their own Kubernetes configuration file. Reading resources from istio-system: $ kubectl apply -f - <
