Welcome to the Basics of Docker.
You will learn how to run the most often used commands in day to day work with docker.
Congratulations! You can start the next exercise in this series.
To launch a container in docker we specify the following
docker run -d nginx
The -d means run in detached mode.
This doesn't allow us to access our nginx instance though as we didn't expose it!
Let's try again:
docker run -d -p 8081:80 nginx
Now you should be able to access the basic html website with:
curl docker:8081
To see currently running containers run:
docker ps
If you want to see the whole output:
docker ps --no-trunc
