Are you aware that AWS has an ECS service for Docker containers? This removes a layer of VM Node management. Base questions: How much AWS do you know? How much Docker do you know? How much Linux do you know?

In a one time scenario you have these options:

A: To transfer your image:

1. Save your image on your local machine:

   docker save my_image > my_image.tar

2. Upload tar to your remote server:

   scp my_image.tar user@aws-machine:.

3. Load image on your remote machine:

   ssh user@aws-machine

   docker load < my_image.tar

4. Run a new container

   docker run my_image

B: To transfer your container:

1. Export your container on your local machine:

   docker export my_container_id > my_container.tar

2. Upload tar to your remote server:

   scp my_container.tar user@aws-machine:.

3. Load tar as image on your remote machine:

   ssh user@aws-machine

   cat my_container | docker import - my-container-exported:latest

4. Run a new container

   docker run my-container-exported:latest

To be prepared for later deployment improvements (like using CD/CI) you should consider option A. All necessary data for execution should be in the image and important data should be stored externally (volume mount, database, ..)

The official Docker image is based on Alpine Linux, which uses the apk package manager.

Try replacing your apt-get commands with the following instead:

Copy    - apk add openssh-client

There is no need to install sudo, just to install openssh-server, so that step was removed.

Hi Rajeev Bagra 1.Docker Installation: Update the package index: ``` sudo apt update ``` Install prerequisites: ``` sudo apt install apt-transport-https ca-certificates curl software-properties-common ``` Add the Docker GPG key: ``` curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - ``` Add the Docker repository: ``` sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" ``` Update the package index again: ``` sudo apt update ``` Install Docker: ``` sudo apt install docker-ce `` Verify that Docker is installed: ``` sudo docker --version ``` 2.Pushing Images to Docker Registry: Log in to your Docker registry: ``` docker login ``` Tag your Docker image with the registry URL: ``` docker tag : /: ``` Push the tagged image to the Docker registry: ``` docker push /: ```

Run sudo netstat -nltpu to confirm what application is running on that port. If it is docker then it means you probably didn't kill the previous docker container that was running on that port. If you don't have any other containers running, you can just stop all containers using this docker stop $(docker ps -a -q)

If you have other containers running, you can run docker ps to get details of the container running on that port, then run docker stop CONTAINER_ID to stop the container.
