What’s the point: Tumblr sharpens Docker pruner, Spinnaker sails over Google, Azure and GitHub, Serverless Framework

What's the point

The tech team at Tumblr has open sourced a Docker Registry Pruner to apply retention policies to Docker Images. The team said the tool was the result of its building up a “huge amount” of Docker containers over the last five years – ranging from a few hundred MB to a few hundred GB – and accumulating in the Registry, eating up storage and slowing down Registry metadata operations. Docker Registry Pruner allows retention policies to be set for images in an API v2 compatible registry. Rules are set using at least one of four selectors, and one of three possible actions. 

Google spreads Spinnaker over cloud platform

Google has unfurled Spinnaker for its Google Cloud Platform. The search giant describes Spinnaker as ”an open-source multi-cloud continuous delivery platform” it co-developed with Netflix. The GCP flavour will come with built-in deployment best practices, and will span Google’s Kubernetes, Compute and App Engine services as well as other clouds or on-prem targets. Unsurprisingly it is integrated with other relevant Google services including Cloud Build, Binary Authorisation and Stackdriver.

Microsoft opens up Azure DevOps to GitHub devs


Microsoft has tightened the integration between its Azure DevOps platform and its GitHub subsidiary just a little bit more by allowing admins to import their GitHub collaborators into the Azure platform. Another wave of features debuted this week allow admins to sign into Azure DevOps using their GitHub IDs and invite GitHub team members from the project homepage or from the user hub. Collaborators can be tracked down by username or display name, and once corralled in, admins can share their Azure DevOps org URL to enable them to sign into the project. The move builds on Microsoft decision in May to allow to sign into Azure DevOps with their GitHub credentials.
