Docker Hub is a service provided by Docker for finding and sharing container images with your team. It is the world’s largest repository of container images with an array of content sources including container community developers, open source projects and independent software vendors (ISV) building and distributing their code in containers.
The pipeline will package the application into a Docker image. It then pushes that image a public Docker Hub image repository so that it will be available to the deployment segment of the pipeline. To push or upload the newly-built Docker image, the pipeline will need an access token to authorize transaction on your Docker Hub account. You will need to create a new access token and store it for use in later modules. To create your new access tokens:
Docker Hub credentials and access tokens must be protected and not shared with unauthorized parties to prevent exposure and unauthorized access.
Now that you have created and safely recorded your new access token, let’s move to the next section and create a new Snyk Access token.
