Task 1 : Installing Docker and Running a nginx container.
- Update the system.
sudo apt update && sudo apt upgrade
- Install docker and give necessary permissions.
sudo apt install docker.io
sudo usermod -aG docker $USER
sudo chmod 666 /var/run/docker.sock
- Check Docker version.
docker --version
- Pulling and running a nginx image from Docker Hub.
docker run nginx
- Check the running containers.
docker ps
Task 2 : Exposing Docker container to outside world using port mapping.
We have successfully ran docker container , but it is only accessible inside our machine , to access our nginx container from browser we have to do port mapping ( map port of the host to port of the container).
docker run -d -p80:80 nginx
Task 3 : Add port in Inbound Security Group.
To access our container from the browser we need to add port 80 in inbound security groups.
Task 4: Access the running container from browser.
We can access the container from brower using Public IP of AWS instance and port 80.
<Public ip address of EC2>:<Port>
Ex- 20.207.168.210:80
Task 5 : Stop the running containers.
As we can access the nginx container from the browser, Lets see how we can see the running containers and stop them .
- See all running containers.
docker ps
- See all running and stopped containers.
docker ps -a
- Stop a running container ( we can stop a running container by container id ).
docker stop < container-id >
Ex - docker stop e5b001d7141e
