Could your business benefit from using Docker Hub Containers? Is Docker Pricing a cause for concern when choosing to implement Docker within your framework?
With modern App development becoming increasingly complex and requiring multiple languages, frameworks, architectures and interfaces, A Docker Subscription offers its users a solution to help simplify the process of app development. This assists both individual developers and larger teams in removing the need to build and create complicated pipelines to manage their containers.
There are multiple Docker Hub packages and subscriptions available for various levels of usage and team sizes – from individual developers to large organisations. Here we will discuss the benefits of using Docker Hub as well as the subscription and Docker pricing options available for users.
What is a Container?
Containers are standard unit software packages which allow app developers to package up everything needed to run an application. This includes;
- System Tools
- System Libraries
Use of a container enables the application to run quickly and reliably from one computing environment to another and allow units to be standardized for development, shipment and deployment.
Docker Hub Container Image Library
Launched in 2013, Docker Hub offers the usage of container images – boasting the world’s largest collection of container images with over a billion options available for use.
A Docker container image acts as a lightweight, executable software package encompassing all of the above aspects needed to run an application. The container images become containers at runtime when run on Docker Engine, which is available on both Linux and Windows applications and can run on either infrastructure. This ensures that despite differences in development and staging, the containers can isolate the software from its environment.
Docker Pricing & Subscriptions for Individuals & Teams
Docker Hub offers a range of subscription choices catered for use by both individuals and organisations. Each subscription is priced depending on the plan needed. Docker Subscriptions are based on a monthly or annual basis and work on a per-seat pricing structure.
Docker Hub Pricing and Subscription Options
Here we will discuss the individual Docker Subscriptions, their pricing and the user case for each subscription option.

The Team plan encompasses all the benefits of the other subscription options plus a range of extras including; Unlimited teams, 3 Parallel builds per organisation, collaborators for both private and public repositories (up to organisation size) and unlimited Hub Image Scans.
For Larger Teams
For larger teams of more than 500 users, Docker offers larger team pricing. Users can contact Docker sales for more information and pricing for a subscription to suit their team size.
Upgrading your Docker Plan
Should users want to upgrade their Docker Billing Plan to access more features or add more users, they can upgrade their subscriptions. Users on a free plan may need to access the extra benefits and features of the Pro Plan or those on any of the individual plans can upgrade to a team plan for more users.
Upgrading a Docker Plan can be be done through accessing the ‘Billing’ section of their Docker Hub Account and choosing ‘Change Plan’. This will allow users to review and confirm their required upgrade. When the upgrade is complete, an email and invoice are generated to confirm cancellation of the original subscription and details of the new subscription, it’s entitlements and new pricing information.
Subscriptions can also be updated from monthly to annual plans (which offer reduced pricing). This can be accessed through the Docker Hub Account and the Billing Section. Users must select ‘Switch to Annual Billing’ to review and confirm the change in their subscription. Once the switch of account is complete a confirmation invoice is generated with details of the new plan, entitlements and costs.
Downgrading your Docker Plan
There may be instances where users want to downgrade their Docker Hub subscription. For example, those on a Pro Plan may no longer require the advanced features offered and want to return to a free plan. In other cases, those on Team Plan may wish to reduce the number of users to a single developer and want to modify their subscription to a free or pro plan.
Downgrading plans can be completed in a similar way to the upgrading process. Simply access the Docker account settings, select the ‘Billing’ option and choose ‘Downgrade Plan’ for the new plan you want to switch to (Choose Free Plan if you want to cancel a paid subscription).
When this downgrade process is complete, a new invoice will be created to reflect plan changes and new pricing details.
Docker Automated Build
Docker Automated Builds create an automated system that uses source code to automatically build images in an external repository before being pushed into a Docker repository.
How Autobuild Works: The auto build can be set up using a list of branches and tags your require to build the images and when the code is pushed to a source code branch for one of the image tags, this causes a webhook trigger to create a new image build. The newly created Docker image is then pushed to the required Docker Hub registry.
Working with Docker Registry
For those wanting to host their own registry, Docker Registry offers a server-side application that enables users to store and distribute Docker Images. The Registry is open-source, serverless, highly scalable and offers tight control over where images are stored. This allows users to own full image distribution pipelines and integrate storage and distribution in to in house workflows.
