Just like you can push your code to Github/Gitlab.

You can push images to docker registries

Docker Hub: The main public repository for Docker images. You can find a wide variety of pre-built images for popular software like Node.js, MongoDB, PostgreSQL, etc. Simply pull an image using:

javascript 
Copy code
docker pull <image-name>

javascript 
Copy code
docker pull node

Private Repository : If you're working in a company, you might store Docker images in a private repository. Docker Hub allows private repositories, or you can use alternatives like:

AWS Elastic Container Registry (ECR)

Google Container Registry (GCR

Azure Container Registry (ACR)

You can create your own Docker image using a Dockerfile that specifies the dependencies and setup for your app. Build the image with:

javascript 
Copy code
docker build -t <your-image-name> .

GitHub Packages: You can store Docker images in GitHub's package registry, useful for integrating with your CI/CD workflows.

javascript 
Copy code
docker pull <image-name>

example:

javascript 
Copy code
docker pull node

javascript 
Copy code
docker images

javascript 
Copy code
docker rmi <image-id>

javascript 
Copy code
docker run -d --name <container-name> <image-name>

example:

javascript 
Copy code
docker run -d --name my-app node

javascript 
Copy code
docker ps

javascript 
Copy code
docker ps -a

javascript 
Copy code
docker stop <container-name>

javascript 
Copy code
docker rm <container-name>

javascript 
Copy code
docker start <container-name>

javascript 
Copy code
docker exec -it <container-name> /bin/bash

These commands will help you navigate Docker from basic usage to more advanced operations. Keep this cheat sheet handy as you work with Docker! Happy coding! 🚀
