Hello dear FibaCloud followers! Today, we’ll explore how to set up orchestration on your local server with the indispensable technologies of the modern software world: Docker and Kubernetes. We will provide a step-by-step guide for installing Docker on both Ubuntu and CentOS operating systems, help you create a local Kubernetes cluster with Minikube, and discuss the advantages these powerful tools offer. If you’re ready, let’s open the doors to the world of microservices!
Docker: Portability and Flexibility of Software
Docker allows you to create containers, which are isolated environments that bundle your applications and dependencies together. This enables you to run your applications seamlessly across different environments (development, testing, production). The portability and flexibility provided by Docker accelerate and simplify the software development process.
Installing Docker on Ubuntu and CentOS:
# Follow these steps to install Docker:
# Remove old versions (optional)
# For Ubuntu:
sudo apt-get remove docker docker-engine docker.io containerd runc -y
# For CentOS:
sudo yum remove docker\
docker-client\
docker-client-latest\
docker-common\
docker-latest\
docker-latest-logrotate\
docker-logrotate\
docker-engine -y
# Install required packages
# For Ubuntu:
sudo apt-get update -y && sudo apt-get install -y \
ca-certificates\
curl\
gnupg\
lsb-release
# For CentOS:
sudo yum install -y yum-utils
# Add Docker's official GPG key
# For Ubuntu:
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
# For CentOS:
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
# Add the Docker repository
# For Ubuntu:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu\
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
# Install Docker Engine
# For Ubuntu:
sudo apt-get update -y
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin -y
# For CentOS:
sudo yum install docker-ce docker-ce-cli containerd.io -y
# Start and enable the Docker service
# For Ubuntu and CentOS:
sudo systemctl start docker
sudo systemctl enable docker
# Verify that Docker is running properly
sudo docker run hello-world
Kubernetes: Container Orchestration
Kubernetes is an open-source platform for managing Docker containers. Kubernetes enables the automatic deployment, scaling, management, and monitoring of containers. This allows you to easily manage complex microservice architectures and achieve high scalability.
Creating a Local Kubernetes Cluster with Minikube:
Minikube is a tool that allows you to run a single-node Kubernetes cluster on your local machine. It provides an ideal environment to try, learn, and develop with Kubernetes.
# Follow these steps to install Minikube:
# Download and install Minikube
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube && rm minikube-linux-amd64
# Start minikube cluster
minikube start
# Interact with the cluster using Kubernetes commands
kubectl get nodes
Microservice Architecture with Docker and Kubernetes
Docker and Kubernetes are the fundamental building blocks of microservices architecture. Microservices architecture streamlines development and deployment processes by breaking large and complex applications into smaller, independent and manageable services. While Docker runs each microservice in a separate container, Kubernetes provides the necessary infrastructure to manage and scale these containers.
Docker and Kubernetes Integration with FibaCloud
FibaCloud is a powerful cloud computing platform that supports Docker and Kubernetes. You can easily create, manage and scale Kubernetes clusters with the Kubernetes service offered by FibaCloud. Additionally, you can safely store and share your Docker images with FibaCloud’s Docker image repository.
We hope this article has provided you with useful information on setting up native orchestration with Docker and Kubernetes. By exploring the Docker and Kubernetes solutions offered by FibaCloud, you can benefit from the power of microservices architecture and make your applications faster, more reliable and more scalable. See you in our next article!
Frequently Asked Questions (FAQ)
What is the difference between Docker and Kubernetes?
Docker is a tool for creating and running containers. Kubernetes is an orchestration platform used to manage and scale Docker containers.
Why should I use FibaCloud Kubernetes instead of Minikube?
Minikube is ideal for local development and testing. However, for greater scalability and reliability in production environments, you may prefer a cloud-based solution like FibaCloud Kubernetes.
Is it difficult to learn Docker and Kubernetes?
Docker and Kubernetes may seem a bit complex at first. However, with FibaCloud’s comprehensive documentation and support resources, you can easily learn these technologies.
