Docker Guide

What is docker?

Getting Started

Download docker and install it on your computer

  • Link to developer guide –
  • Select the docker option based on your operation system. In my case, I selected Docker for desktop mac. Then from there should be a link to download the docker executable onto your computer.
  • You will have to create a docker account to download docker.
  • Install docker by double-clicking on the executable your downloaded and follow instructions.

Docker commands

You are going to use the command-line interface to work with Docker.

docker images
– list out all the images in your computer

docker ps -a
– list out all the running containers on your computer

docker rmi imageId
– delete or remove an image.

docker stop containerId
– stop a running container

docker rm containerId
– delete a container

docker pull image: tag
– pull an image from a docker registry(docker hub or AWS ECR).

docker pull mysql


Run docker container automatically

Use these tags 

-dit --restart unless-stopped

docker run -p outside-port:internal-port –name container-name -dit –restart unless-stopped -d image_name:image_tag
– run docker container with the port where the container will use both externally and internally, the name of the container, the image, and tag being used, and a command to make sure the container will restart if it stops.

– -d means that to run container in background and print container ID

docker run -p outside-port:internal-port --name container-name -dit --restart unless-stopped -d image_name:image_tag
docker run -p 8080:8080 --name springboot-hello-0-0-1 -dit --restart unless-stopped -d springboot-hello:0-0-1


Push up a docker image to aws docker registry

1. Login to aws ECR from your computer

aws ecr get-login-password --profile folauk110

2. Build image

docker build -t project .

3. Tag image

docker tag project:latest remote-ecr-url/project:latest

4. Push image to remote registry

docker push remote-ecr-url/project:latest


SSH into a docker container

docker exec -it {container-name} sh


docker exec -it {container-name} sh /bin/bash
