My actual requirement is pull docker image from GitHub and build a docker image in ec2 instance and push that image to ecr. So, am just trying to clear my first step by asking help to pull image from git, very new to all this.
Let's walk through each step you're asking about in your requirements:
Pull from GitHub - You won't pull a docker image from here, however you may pull a Dockerfile from here, which would be used to build an image. The command to do this would be just like cloning any other repository: git clone <repository url>
Build the image on ec2 - First you will need to have docker installed on the ec2 instance. Assuming you're running Ubuntu on your ec2 instance, follow the good instructions on Docker's page (https://docs.docker.com/install/linux/docker-ce/ubuntu/) miror. Once docker is installed, navigate to the directory that has your Dockerfile in it (cloned from git) and type docker build . --tag mytag
Push the image to ecr - To do this, you need to have the amazon CLI installed on your box, and you need an ACCESS_KEY_ID and SECRET_ACCESS_KEY from AWS IAM. Once you have these, configure your connection by storing them as environment variables, or by typing aws configure and entering them. Once your credentials are configured, log into ECR by typing aws ecr get-login --no-include-email, and then copy/pasting the command it gives you. (you can also put ` around it to skip the copying step). This will allow you to push to ecr using docker push.
To clarify some of the points:
Github: It is a web-based hosting service for version control using git. So you can not pull docker image from Github.
To build a Docker image, you need Dockerfile. So you can fork the GitHub project which has this Dockerfile.
Then to build it on ec2, you can check out the project containing Dockerfile on ec2 server and build it using:
https://docs.docker.com/engine/reference/commandline/build/
and then you can push it to any registry using:
https://docs.docker.com/engine/reference/commandline/push/

We've just brought Artifactory into our organization. We have a lot of Fargate stacks that are pulling the Docker images from ECR. We now want to pivot and store our Docker images in Artifactory and tell Fargate to pull the images from Artifactory.
Does anyone know how to do this?
Thanks
An Artifactory repository for Docker images is a Docker registry in every way, and one that you can access transparently with the Docker client (see documentation)
In Artifactory, start by creating a local Docker repository, then follow the "Set Me Up" instructions for that repository to upload/deploy your docker images to it.
The "Set Me Up" dialog for the Docker repository also provides the steps to have your docker clients consume/download the images from your Docker repository/registry. You would just have to replace the references of ECR with the one for your Artifactory docker repository/registry in your docker client commands.
This documentation page provides step-by-step information on how to use Artifactory as a Docker registry.
Artifactory also provides the capabilities of Remote Docker repositories, which provides proxying/caching of external registries, and Virtual Docker repositories for the aggregation of both local and remote repositories into one single entry point.
I have an docker public image, Now for some reason we had to shift it to AWS ECR,Now I am able to transfer the image to ECR from docker hub, but how to make sure that all the stable release in dockerhub will be pushed to AWS ECR, I want my ECR repo update with latest dockerhub image all the time.
You might consider building and publishing your Docker image through GitHub and its CI (Continuous Integration) GitHub Actions option.
That way, you can, in your GitHub workflow, chain:
Publish-Docker-Github-Action: Publishes docker containers to DockerHub
appleboy/docker-ecr-action: Uploads Docker Image to Amazon Elastic Container Registry (ECR).
Each time you are publishing a new version of your image, it would also be available in ECR.

I am trying to deploy docker containers from my local machine, test them on Travis CI, Build them and push them to the Container Repository, and then deploy them on my gcloud compute instance. But I can't figure out how to do it and was wondering if someone had done this before and if they could point me to some material that would help me.
Let's start with Docker: here you can find how to use Docker with Travis CI. At first, you need to install Docker and Google recommend to use version 18.03 or newer because it's required to use gcloud credential helper for authentication. Also, you need to install Google SDK and enable billing for your project. Check that you have permission to push and pull images to Google Container Registry and don't forget to enable Container Registry API in your project. After that, you can build Docker image, tag it with a registry name, push the image to Container Registry and than you'll be able to pull your images into your project. More information with examples and step by step instructions you can find here and here.
I have a jenkins in a standalone Windows 7 server. We have a request to add a build job to build a project, which produce a Docker image in Tar ball format, and push the image into a remote Docker Registry, which resides in OpenShift.
Trying to find a jenkins plugin that can do this. Found that Docker Common plugin have some command but as i understood it can push the image only from a docker registry to another.
Any guide where i can push the tar ball to a remote registry through a standalone jenkins? Thank you.
may be this can be helpful, you can run docker on local windows server, and then load the image tar to local docker then push it to remote repo. Steps are given in this link.

I have a docker file which copies some code from git. When I put this docker file as part of Azure devops pipeline I am unable to get the code inside container. is git clone the only option or is there any way out of this?
The container is not having internet access to connect to the git repository. You can prebuild your image from local system and use the image from docker images registry.
