Open Tools Help Streamline Kubernetes and Application Development

Kubernetes tools

Organizations everywhere are implementing container technology, and many of them are also turning to Kubernetes as a solution for orchestrating containers. Kubernetes is attractive for its extensible architecture and healthy open source community, but some still feel that it is too difficult to use. Now, new tools are emerging that help streamline Kubernetes and make building container-based applications easier. Here, we will consider several open source options worth noting.

Microsoft’s Kubernetes Moves

Microsoft has just open sourced Draft, a tool that streamlines application development and deployment into any Kubernetes cluster. “Using two simple commands, developers can now begin hacking on container-based applications without requiring Docker or even installing Kubernetes themselves,” writes Gabe Monroy, PM Lead for Containers at Microsoft. “You can customize Draft to streamline the development of any application or service that can run on Kubernetes.”

In April, Microsoft acquired the Deis container platform from Engine Yard, and Draft is a direct result of that acquisition. “Draft targets the ‘inner loop’ of a developer’s workflow while developers write code and iterate, but before they commit changes to version control,” notes Monroy. “When developers run ‘draft create’ the tool detects the application language and writes out a simple Dockerfile and a Kubernetes Helm chart into the source tree. Language detection uses configurable Draft ‘packs’ that can support any language, framework, or runtime environment. By default, Draft ships with support for languages including Node.js, Go, Java, Python, PHP, and Ruby.”

In acquiring the Deis container platform from Engine Yard, Microsoft also became a steward, along with the Cloud Native Computing Foundation and several other organizations, of Helm, which is billed as “the best way to find, share and use software built for Kubernetes.” It is essentially an open Kubernetes package manager. “Helm Charts help you define, install and upgrade even the most complex Kubernetes application,” note the community leaders.

The Kubernetes blog notes the following about Helm: “There are thousands of people and companies packaging their applications for deployment on Kubernetes. This usually involves crafting a few different Kubernetes resource definitions that configure the application runtime, as well as defining the mechanism that users and other apps leverage to communicate with the application…We began to provide a home for Kubernetes deployable applications that provides continuous releases of well documented and user friendly packages. These packages are being created as Helm Charts and can be installed using the Helm tool. Helm allows users to easily templatize their Kubernetes manifests and provide a set of configuration parameters that allows users to customize their deployment.”
