- minimum 4GB RAM (if you are planning to use multiple containers)
- Docker software repository (hub.docker.com)
Docker & Container Fundamentals:
Docker allows you to package an application with all of its dependencies into a standardized unit, called a container, for software development. A container is a stripped-to-basics version of a Linux operating system. An image is you load into a container.
Installing Docker in Ubuntu:
Step 1: To install the docker to your system, you should first add the GPG key using curl – https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add
The added files can be checked in the directory to verify if the key has been added.
Step 2: The sudo apt-get update, is used to install the necessary package get updates.
Step 3: Now install the docker using sudo apt-get install -y docker-

→ Now, both your and repository up, but it needs to be linked to work simultaneously.
→ Before that the image is pushed into the using docker push /verse_gapminder.
→ Now the docker is linked with by id/ and.

A new directory using packet. Once this is created the same using install.
