StackHawk sponsors Devops Weekly
Join StackHawk and WhiteSource tomorrow morning to learn about automated security testing in the DevOps pipeline. With automated dynamic testing and software composition analysis, you can be sure you’re shipping secure APIs and applications. Grab your spot:
A good introduction to the pros and cons of tags for Docker images and how to implement repeatable builds using digests.
A nice write-up of progress with the Tinkerbell open source project, which provides a full toolchain for bare metal provisioning.
A purposefully provocatively titled post with some good observations; nobody cares about the operating system anymore.
A quick post on getting started with CINC Auditor, the open packaging for Chef Inspec.
A post explaining the concepts behind policy as code and how the author came to appreciate the idea and the open policy agent project.
A case study of adopting the new ARM-based Graviton instances in AWS, and the resulting price and performance improvements.
A post on building decision trees for threat modelling with Graphviz. It’s a nice graphviz DSL tutorial as well.
Every discussed DNS propagation? As this post points out, It doesn’t exist and it’s a matter of layered caches.
An interesting service management survey looking for input. The post has some good data points from the previous years survey too.
