Using Docker on AWS EC2 with Ubuntu | 點燈坊

Default Ubuntu on AWS EC2 doesn’t provide Docker and Docker Compose. We have to install them manually.

Docker 20.10.7
Docker-compose 1.25.0

$ sudo apt-get update

Update package list to latest version.

Add Required Packages

Add Official GPG Key

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Add official Docker GPG key to source.

Add Docker

$ sudo apt install docker.io

Add Docker to system.

$ docker --version

Docker installed successfully.

Add Docker Compose

$ sudo apt install docker-compose

Add Docker Compose to system.

$ docker-compose --version

Docker Compose installed successfully.

Add ubuntu to Docker Group

$ sudo usermod -a -G docker ubuntu

Hello World

$ docker run hello-world

• Re-login SSH, we can run Docker command without sudu becuase we’ve added ubuntu to docker group
• Use Docker to run hello-world

Conclusion

• After installing Docker and Docker Compose on AWS EC2, we can use Docker just like using it on local machine
