Docker is an essential tool for creating and managing containers, allowing applications to run in an isolated and portable manner. On Windows Server, the process of installing and configuring Docker is relatively simple but requires attention to some details. In this guide, we will explain step-by-step how to install Docker on Windows Server and run your first container.
Requirements
Before you start, make sure your system meets the following requirements:
- Operating System: Windows Server 2016 or later.
- Permissions: Administrator access on the server.
- Updates: Install the latest Windows updates to ensure compatibility.
Step 1: Install Docker on Windows Server
1.1 Enable the Container Feature
Docker on Windows uses the container feature, which needs to be enabled. Run the following commands in PowerShell as an administrator:
Install-WindowsFeature -Name Containers -IncludeAllSubFeature -RestartAfter execution, the system will restart.
1.2 Install the Docker Module
After restarting, run this command to install Docker:
Install-Module -Name DockerMsftProvider -Repository PSGallery -Force1.3 Install Docker
Now, install Docker with the command:
Install-Package -Name docker -ProviderName DockerMsftProvider -ForceWait for the installation. After completion, restart the server again:
Restart-Computer -Force1.4 Verify the Installation
After restarting, verify that Docker was installed correctly by running:
docker versionThis command should return information about the Docker client and server.
Step 2: Configure Docker
2.1 Enable the Docker Service
Ensure that the Docker service is configured to start automatically:
Start-Service docker
Set-Service docker -StartupType Automatic2.2 Verify Docker Functionality
Run the following command to check if Docker is active and functional:
docker run hello-worldThis command downloads and runs a test container called hello-world, ensuring that Docker is configured correctly.
Step 3: Run a Container on Docker
3.1 Choose an Image
Docker images are templates used to create containers. You can search for an image on Docker Hub with the command:
docker search nginx3.2 Download the Image
Download the chosen image with the command:
docker pull nginx3.3 Run the Container
Run the container from the downloaded image:
docker run -d -p 80:80 --name meu-nginx nginx-d: Runs the container in the background.-p 80:80: Maps port 80 of the host to port 80 of the container.--name meu-nginx: Names the container asmeu-nginx.
3.4 Verify the Container
List the running containers with:
docker psAccess the container in the browser using the server’s IP address on port 80.
Step 4: Manage Containers
- Stop a Container:
docker stop meu-nginx- Remove a Container:
docker rm meu-nginx- Remove an Image:
docker rmi nginxConclusion
With Docker installed and configured on Windows Server, you are ready to use containers in your projects. This process simplifies application management, increases portability, and improves the efficiency of the environment. Try creating your own containers and take advantage of Docker in your workflow.
