You’ll also need a user account with sudo privileges and access to the root user account. I’ll be demonstrating on two CentOS 8 servers, running on IP addresses: In order to successfully install Kubernetes (and create a cluster), you’ll need at least two machines. If you’re looking to deploy a Kubernetes cluster on CentOS 8, the changes made to the operating system will directly affect you.īut how? Although they don’t change the way you deploy the actual cluster, getting everything in place for the deployment is quite different.įear not, I’m going to walk you through the process of installing Kubernetes on CentOS 8, so you can then get back to the business of deploying your cluster and managing your containers.

Now open the web browser and type the CentOS IP address with the following format For example: Portainer create a new user You can install Portainer with this simple command docker volume create portainer_dataĭocker run -d -p 8000:8000 -p 9000:9000 -name=portainer -restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer We can easily run the various applications, pull images, and manage Docker installation via a web browser. Portainer is a graphical Docker management. ![]() Now let’s run hello-world docker run hello-world Install Portainer on CentOS 8 ![]() We will try to pull an image from the Docker repository. Now reboot CentOS for the change to take effect. In order to allow Docker containers to communicate with the network, we need to disable firewalld on CentOS. If you want to add the normal user to Docker group, do the following sudo usermod -aG docker $USER Disable firewalld By default, only root and sudo user that can run and manage Docker. ![]()
