Deploying a Containerized Application with Docker on ServerStadium
In this tutorial, we’ll guide you through the process of setting up Docker on a ServerStadium VM instance and deploying a containerized application. This approach is ideal for creating isolated, scalable, and efficient application environments.
Prerequisites
Ensure you have a ServerStadium account and a VM instance ready. If not, register and set up your VM instance via the Cloud Panel.
Step 1: Set Up Your ServerStadium VM Instance
Log into the ServerStadium Cloud Panel and create a new VM instance. Choose an operating system that is compatible with Docker, such as Ubuntu 20.04 or 22.04. You can find suitable VM configurations and pricing details on our pricing page.
Step 2: Install Docker
Once your VM instance is ready, connect to it via SSH. Update your package list and install Docker:
sudo apt update
sudo apt install docker.io
Start and enable Docker:
sudo systemctl start docker
sudo systemctl enable docker
Verify the installation:
docker –version
Step 3: Working with Docker Containers
Docker allows you to run applications in containers. For this tutorial, let’s run a simple “Hello World” container to demonstrate:
docker run hello-world
This command pulls the “Hello World” image from the Docker Hub and runs it in a container. You should see a message indicating that your Docker installation is working correctly.
Step 4: Deploy Your Containerized Application
Now, let’s deploy a more complex application. For example, you might want to run a Nginx web server. Pull the Nginx image from Docker Hub:
docker pull nginx
Run the Nginx container:
docker run -d -p 80:80 –name mynginx nginx
This command runs Nginx in a detached mode, maps port 80 on the container to port 80 on your VM, and gives the container a name.
You can now access your Nginx server by visiting your VM’s IP address in a web browser.
Step 5: Managing Docker Containers
Learn basic commands to manage your Docker containers:
- List running containers:
docker ps - Stop a container:
docker stop mynginx - Start a stopped container:
docker start mynginx - Remove a container:
docker rm mynginx
Conclusion
You’ve successfully set up Docker on your ServerStadium VM and deployed a containerized application. Docker, combined with ServerStadium’s VM instances, offers a powerful platform for developing and deploying applications with ease and efficiency.
