How to connect to Azure AKS Kubernetes worker node by SSH

Nodes are not assigned public IP. If you have accessible VM in the same VNET as worker nodes, then you can use that VM as jump host and connect the worker via private IP.

Alternatively public IP can be assigned to a worker node. This readme shows how to do that.

Steps how to attach public IP to a worker node

find out the resource group that AKS created for the node VMs

Tuning Intel Skylake and beyond for optimal performance and feature level support on Linux:

Note that on Skylake, Kabylake (and the now cancelled "Broxton") SKUs, functionality such as power saving, GPU scheduling and HDMI audio have been moved onto binary-only firmware, and as such, the GuC and the HuC blobs must be loaded at run-time to access this functionality.

Enabling GuC and HuC on Skylake and above requires a few extra parameters be passed to the kernel before boot.

Instructions provided for both Fedora and Ubuntu (including Debian):

Note that the firmware for these GPUs is often packaged by your distributor, and as such, you can confirm the firmware blob's availability by running:

Nice post! Finally some clarification on the different interpretations of what an application, library or wrapper cookbook is :-)

I have one question about the environment cookbooks though: what if you have two different applications (e.g. my_face and your_face) requiring a different set of dependencies running in the same environment?

IMHO locking dependency versions and exposing the public recipes / attributes via metadata.rb is a great thing, but it should be doable on a finer-grained basis than environments, namely on a per application (e.g. my_face) basis. For this exact reason I'm not using chef environments to lock the dependency versions, but rather something like an "uber application cookbook" which combines the properties of an application cookbook and the locking and documentation of an environment cookbook.

What do you think? And what would be a good name for it?

Build your own private, encrypted, open-source Dropbox-esque sync folder

Prerequisites:

• One or more clients running a UNIX-like OS. Examples are given for Ubuntu 12.04 LTS, although all software components are available for other platforms as well (e.g. OS X). YMMV
• A cheap Ubuntu 12.04 VPS with storage. I recommend Backupsy, they offer 250GB storage for $5/month. Ask Google for coupon codes.

Software components used:

• Unison for file synchronization
• EncFS for folder encryption

Unionize: network superpowers for your docker containers

Unionize lets you connect together docker containers in arbitrarily complex scenarios.

Note: I recommend to use https://github.com/jpetazzo/pipework instead.

• pipework is a better name than unionize
• it's hosted on a "real" github repo instead of a small gist :-)

Now if you want Unionize, it's still here. Just check those examples.
