Go 1.9 RC1 available now

First release candidate of programming language from Google team released
26 July 2017   451

Good news for all Go developers. Go 1.9 Release candidate 1 is out now.

Let's see what's inside!

There are two changes to the language: adding support for type aliases and defining when implementations may fuse floating point operations. Most of the changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before.

The release adds transparent monotonic time support, parallelizes compilation of functions within a package, better supports test helper functions, includes a new bit manipulation package, and has a new concurrent map type.

Develoeprs ask to report any problems using the issue tracker. 

If you have Go installed already, the easiest way to try go1.9rc1 is by using this tool.

You can download binary and source distributions from the usual place.

Documentation for Go 1.9 available here.

Brigade launched

Event-driven scripting tool for Kubernetes released by Microsoft
31 October 2017   444

Microsoft has unveiled its new Open Source development for the needs of DevOps, a Brigade utility designed to run scripts that are executed on a Kubernetes cluster on an event.

The Brigade utility was created by former employees of Deis, a company that Microsoft bought earlier this year. Deis was working on Kubernetes, Helm and Draft. The purpose of Brigade is to "script simple and complex workflows using JavaScript." The solution allows to associate containers by running them sequentially or in parallel and invoking scripts based on time, events in GitHub (also supported by "DockerHub and other popular web services"), push operations in Docker or other triggers. Readme of the project describes it as "a tool for creating pipelines for Kubernetes".

Brigade architecture 

Brigade is written in Go and TypeScript / JavaScript, it functions as a service inside Kubernetes. The job (task) in Brigade is a JavaScript script that is interpreted by the product service, which leads to the creation of the necessary resources in Kubernetes. Next, Brigade expects events and performs the corresponding task trigger. It is assumed that the new solution is well suited for the tasks of continuous integration and delivery of applications (CI / CD), tk. simplifies automated testing, assembly of artifacts and releases, management of software deployment.
