The webinar addressed the challenges of traditional continuous integration and delivery processes, particularly for microservices, where code changes are often first tested at the staging stage, causing delays due to potential integration issues. By leveraging Docker technologies, the webinar suggested that developers can parallelize integration testing and obtain "feature previews" earlier in the development lifecycle. This approach allows for an environment where feature branches can be shared and validated by the team, ensuring not only functional completeness but also alignment with business and customer needs. Early detection of issues in functionality, UI, or integration can prevent costly iterations later in the process. The webinar also recommended using Codefresh for Docker continuous integration, noting its availability for free for open-source projects.
