14 April 2017 The Vamp 0.9.4 release marks the beginning of a new level of sophistication and maturity of the Vamp system. It shows the first features of our longer term vision on what Vamp can be and deliver. One of the most powerful additions is the addition of a Vamp controlled “reverse proxy” functionality. This enables powerful new features like showing logs of running container instances, showing the contents of the containers itself, and exposing event-logs from all the Vamp workflows, all directly within the Vamp UI. With this new feature Vamp can effectively act as a unified accesspoint and view to all the components and services running in the system. We’ve also added support for importing and converting Docker Compose files to Vamp blueprints. Another powerful addition is now defining health-definitions for Marathon within Vamp blueprints. Much requested is having a smart check on available cluster-resources in Marathon before deploying a blueprint. We have a service instances overview screen now, and better support for health-checks for Vamp containers. We also added an artifact revisions history view to the UI. And of course we’ve fixed plenty of bugs and added numerous enhancements and improvements along the way. Enjoy this new Vamp release and we look forward to building upon these great new core features to deliver even more powerful functionalities in the upcoming releases.

What has changed
- Synchronization when health checks are changed needs to be explicitly specified
- Sometimes errors are logged due to starting of Vamp dependencies
- When in Marathon/DCOS Zookeeper is unavailable/restarted Vamp can sometimes become out of sync, showing failed deployments when the deployments are running normally. Going into scale and saving syncs Vamp again.
- On DC/OS the container logs are not shown by default, it needs setting of the vamp.container-driver.dcos.url to access these and show them in the UI.
