We are rolling out Docker v20 to Pipelines in June 2021

Docker v20 was officially released a few months ago, bringing new features that will make your builds faster and more secure. We will be progressively rolling out the new version to Bitbucket Pipelines throughout the month of June 2021.


Actions required

We do not expect the majority of the builds to impacted by this upgrade. However, if your project is using Pipelines docker service, you might want to review your code and/or dependencies that interact with Docker daemon and update them if needed.

Here is a way that you might use to identify if your build will work on Docker v20:

For example, if you are using testcontainers-java, please consider updating to newer versions (1.15.1 minimum).
