Worked on the rudderlabs/rudder-integrations-config repository to update external integration image references for Marketo, Salesforce, and Zendesk Support, migrating them to AWS ECR-hosted Docker images. This change ensured compatibility with the latest integration versions and improved deployment reliability by standardizing on a private registry. The approach focused on containerization and cloud computing, leveraging Docker and AWS ECR for secure image management. Configuration-driven release engineering was used to streamline updates and reduce reliance on public registries, enhancing maintainability and security. The work was implemented using JSON for configuration updates, with no major defects reported following the deployment of these changes.
