Dokku is an extensible open source Platform as a Service that Healthcare Blocks has supported for many years in EC2 environments. Healthcare Blocks has also funded the development of this project. While AWS provides many choices for application management/deployment such as Elastic Beanstalk and Elastic Container Service, our customers have enjoyed using Dokku because it can be installed in local development environments and it can leverage open source build packs and Docker images.
Dokku's documentation site is the best resource for accessing help corresponding to the version of Dokku installed in your environment. However, we've also published additional quick starts and guides in the Dokku Framework area of our knowledge base.
Healthcare Blocks automatically patches Dokku with minor version updates if these contain security-related fixes. Major version upgrades can be requested through a support ticket and typically do not require any downtime.
