To start using Docker,install the Docker templateand follow these steps:
Connect to Your VPS
OpenTerminal(Linux/macOS) orCommand Prompt/PowerShell(Windows) on your local computer and enter the following command:
<code>ssh root@vps_ip</code>
Replacevps_ipwith yourVPS IP address. You might be prompted to enter your VPS password.
Check the Docker Installation
To verify thatDocker is installed, enter the following command:
<code>docker --version</code>
You will get theDockerversion information if its installed correctly. Now checkDocker Composewith the following command:
<code>docker-compose --version</code>
If installed correctly, this will display the version of Docker Compose.
Deploy Your First Docker Container
Pull asample Docker imageto test your setup. For instance, you can use the Hello World image:
<code>docker run hello-world</code>
This command will download and run the Hello World container.
Start Using Docker Compose
Create a new directory for your Docker Compose project and navigate to it:
<code>mkdir my-docker-projectcd my-docker-project</code>
Once inside your project directory, create adocker-compose.ymlfile using a text editor and define your services, networks, and volumes. Now you can start your services using the following command:
<code>docker-compose up -d</code>
This will start the services defined in your Docker Compose configuration by reading the configuration from thedocker-compose.ymlfile in the current directory. The-dflag stands fordetachedsothat the command runs in the background and returns to the command line instead of showing the logs of the running services.
