Store containers to

If you've just created your first Docker image, maybe you're looking for a place where to store this container ? A repository ?

There are few providers which allow you to store your containers in public or private repositories like

You can create as much as you want of public repositories but you'll have to pay the at least $12 per months in order to create private repositories as it is described on their pricing page. allows you to have public repositories for free and private repositories starting at $7 as described on their pricing page. is highlighting how secure they are. It looks like they investigated a lot more about the security of storing.

In my example I've described in my previous article Containerize with Docker, I have created a main image and 2 tagged images.

I'm going to explain you how to push them to

Repository creation

First of all you have to create a repository.

After having created an account, click the Create a new repository button.

Then select the Public option from the Repository Visibility section.
Next, in the Initialize repository section select (Empty repository).

I have tried to use the Initialize from a Dockerfile, where you just copy/past the content of a Dockerfile, but the server availability was not enough and I have waited several minutes and never had my file executed.
So I'm going to show you the home made way. :-)

Preparing for Shipment

Before to push our image we have to:

  • Login from the terminal to using the sudo docker login command
  • Tag our images for

In order to create the tags we have to execute the following lines:

sudo docker tag zedtux/
sudo docker tag zedtux/
sudo docker tag zedtux/

The first line create the tag for the main image and then we create a tag for the web and worker images.

Now you should have the following Docker images:

Shipment to

Now you're ready to push the images:

sudo docker push
sudo docker push
sudo docker push

It could takes some times depending on the size of your images and your internet connection.

When the upload is finished, you can see the following on

You can now use this repository in order to deploy or share your images. :-)
