How to start a Docker image

Steps to start Docker image:

1. Pull the image: Use the docker pull command to pull the desired image from the Docker Hub or other registry. For example: docker pull ubuntu:latest
2. Create container: Use the docker run command to create a new container based on the pulled image. You can specify the name of the container, the assigned resources, and the commands to run. For example: docker run -it --name my-ubuntu ubuntu:latest bash
3. Start container: Use docker start command to start a created but not running container. For example: docker start my-ubuntu
4. Connect to a container: Use the docker attach or docker exec command to connect to a running container. This allows you to interact with the container and execute commands. For example: docker exec -it my-ubuntu bash

Detailed description:

• Pull the image: When pulling the image, Docker downloads all layers of the image from the registry and stores it locally.
• Create a container: When creating a container, Docker allocates resources, such as CPU, memory, and storage on the host. It also creates the container's network namespace and connects it to the host network.
• Start container: When starting container, Docker starts processes in the container. The container will run until it stops or exits.
• Connect to Container: When connecting to a running container, you can interact directly with the container. This is useful for troubleshooting, debugging, or running commands in containers.
