Installing a Dockerized Program on a Cloud Infrastructure involves the following steps:
Set up your virtual machine (VM) with Docker. You must first establish a secure connection, such as SSH, to your cloud-based virtual computer. Install Docker, the application that facilitates container creation and management, when you’re in. Docker functions similarly to a lightweight virtual machine, allowing you to run your application anywhere by storing it together with all of its dependencies.
Build a Docker file for your program. You must build a Dockerfile inside your project folder, which is where your application files are located. This file functions similarly to a recipe. It instructs Docker which files to include in the container and which base image to use (such as a Linux server with a web server). For instance, you may utilize an NGINX image and copy your website files into it if you’re making a static website.
Create the Docker image. Create an image from the Dockerfile’s instructions using Docker. This picture functions similarly to a snapshot of your program and its surroundings. This image is easily deployable, shareable, and reusable once it has been constructed. To help you recognize your image later, you give it a name.
Launch the Docker container. You construct the image and then use it to run a container. A container is an image in real time. To enable internet access, you connect the internal ports of the container (such as 80 for HTTP) to the public ports of your virtual machine (VM) when it is operating.
Open the application in the web browser. Lastly, you can type the public IP address of your virtual machine into a web browser. You should see your application running live from within the Docker container if everything went according to plan.
