Play with Docker in the browser

Want to experiment with this thing called Docker but don’t want to go through the hassle of installing it? Go to and you are good to go.

In this website you can spin up 5 instances of Linux running for 4 hours. Lets make a webserver running there and see how it all works.

First press ‘Add new Instance’ and a new machine start up.


The machine is running on ip number We need this number later on Star.

Now start a Nginx webserver on port 80:

$ docker run –name docker-nginx -p 80:80 -d nginx


We need one more thing, we want to test the webserver on some public address. With some Ngrok magic this is possible, but be sure to replace the ip address with your ip address Star.

$ docker run –net host -ti jpetazzo/ngrok http


A new server is started on, we can use this address in a browser to test it all.


And it all works Smile

More advanced Docker topics are now also possible, like running multiple containers with docker-compose or a cluster with Docker Swarm.
