Last year at DockerCon and Microsoft Connect, we announced the Cloud Native Application Bundle (CNAB) specification in partnership with Microsoft, HashiCorp, and Bitnami. Since then the CNAB community has grown to include Pivotal, Intel, DataDog, and others, and we are all happy to announce that the CNAB core specification has reached 1.0.
Modern applications can come in many flavors, consisting of different technology stacks and architectures, from n-tier to microservices and everything in between. Regardless of the application architecture, the focus is shifting from individual containers to a new unit of measurement which defines a set of containers working together – the Docker Application. We first introduced Docker Application packages a few months ago. In this blog post, we look at what’s driving the need for these higher-level objects and how Docker Enterprise 3.0 begins to shift the focus to applications. Scaling for Multiple Services and Microservices Since our founding in 2013, Docker –…
Docker App is a new tool we spoke briefly about back at DockerCon US 2018. We’ve been working on `docker-app` to make container applications simpler to share and easier to manage across different teams and between different environments, and we open sourced it so you can already download Docker App from GitHub at https://github.com/docker/app. In talking to others about problems they’ve experienced sharing and collaborating on the broad area we call “applications” we came to a realisation: it’s a more general problem that others have been working on too. That’s why we’re happy to collaborate with Microsoft on the new…
As more organizations pursue cloud-native applications and infrastructures for creating modern software environments, it has become clear that there is no single solution in the market for defining and packaging these multi-service, multi-format distributed applications. Real-world applications can now span on-premises infrastructure and cloud-based services, requiring multiple tools like Terraform for the infrastructure, Helm charts and Docker Compose files for the applications, and CloudFormation or ARM templates for the cloud-services. Each of these need to be managed separately. To address this problem, Microsoft in collaboration with Docker are announcing Cloud Native Application Bundle (CNAB) – an open source,…
