Effortlessly Set Up Docker Compose on Rocky Linux 8

#### Prerequisites Before you begin, ensure you have: - A server running Rocky Linux 8 - A user account with sudo privileges - Docker installed on your system #### Step 1: Install Docker If you don't have Docker installed, you can install it by following these steps: ```bash sudo dnf update -y sudo dnf install -y dnf-plugins-core sudo dnf config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo sudo dnf install docker-ce docker-ce-cli containerd.io -y sudo systemctl start docker sudo systemctl enable docker ``` Verify Docker installation: ```bash sudo docker run hello-world ``` #### Step 2: Download Docker Compose Download the latest version of Docker Compose: ```bash sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose ``` #### Step 3: Apply Executable Permissions Apply executable permissions to the Docker Compose binary: ```bash sudo chmod +x /usr/local/bin/docker-compose ``` #### Step 4: Verify Docker Compose Installation Verify the installation by checking the version of Docker Compose: ```bash docker-compose --version ``` You should see output similar to: ``` docker-compose version 1.29.2, build 5becea4c ``` #### Step 5: Create a Docker Compose File Create a `docker-compose.yml` file for your application. For example, a simple web server setup might look like this: ```yaml version: '3' services: web: image: nginx:latest ports: - "80:80" ``` #### Step 6: Start Your Application Navigate to the directory containing your `docker-compose.yml` file and start your application: ```bash docker-compose up -d ``` This command runs the containers in the background and outputs the container IDs. #### Step 7: Verify the Application Ensure your application is running by checking the status of the containers: ```bash docker-compose ps ``` You should see output indicating that the services are up and running. #### Conclusion You have successfully installed Docker Compose on Rocky Linux 8 and set up a simple application. Docker Compose simplifies the management of multi-container applications, making it an essential tool for developers and system administrators. **Additional Resources:** - **Docker Compose Documentation:** [https://docs.docker.com/compose/](https://docs.docker.com/compose/) - **Rocky Linux Documentation:** [https://docs.rockylinux.org/](https://docs.rockylinux.org/)
