Docker on Raspberry Pi 3

Big Upgrades for Little Devices

By Marcy Nugent, DevOps Engineer

Just look at that tiny server

Developing for Raspberry Pi inspires a sense of wonder at what can be done with tight resources; many services that once required a cluster of expensive servers in a data center can run without issue on this $35 tech toy. On the other hand, the ubiquity of x86 processors makes running common software a challenge – try finding up-to-date versions built for Raspbian (the default OS choice for the Pi) and you’ll quickly find yourself scouring Stack Overflow articles and old blog posts. You can spend hours looking for someone, anyone who has this thing working already. Once building from source seems like the easy way out, you may rethink whether this $35 computer is worth it.

Docker to the Rescue!

Enter Docker.

Now that Docker on ARM has matured into a usable product, it’s trivially easy to install the latest Docker CE engine on a Pi. Once that’s complete, we can really get rolling on the Pi and deliver applications with the same methods you would use on any other device. Using a Dockerfile, we can codify the heinously detailed work of compiling an app for ARM without utterly unmanageable Rasbian shell scripts, ancient apt-get versions, or typing “chmod +x” for every last install script.

Unless this is your idea of fun

The fantastic folks over at Resin.io have done the heavy lifting for us with their ARM-emulating base images, so we can build our software without using a Pi, and simply deliver it via Docker Hub or Quay.io through a “docker pull” command. Check out the RealEyes Github for a Dockerized WireShark Dumpcap implementation and check out our Quay.io repo for the public image, so you can always have a Docker Repository on Quay.

Varnish Software releases three new products to increase website scalability and performance

Released today (Nov 18, 2014) are three new products to add to the Varnish Plus application; Unlimited cache sizing, increased caching performance and customized cache optimization support content-heavy, high-traffic sites.

“For most consumers, websites are now the pivotal point of interaction with companies. If information and content isn’t delivered instantly, they will seek alternatives that are just a mouse-click away,” – Per Buer, Founder and CTO, Varnish Software.

Product details:

Unlimited cache sizing with Varnish Massive Storage Engine
The new Varnish Massive Storage Engine tackles the problems of content-heavy sites by allowing the Varnish caching layer to handle multi-terabyte data sets. This makes it possible to cache almost unlimited objects while the website performance remains stable over time. The Varnish Massive Storage Engine is targeted at business with large data sets such as online retailers, image banks, video distributors or Content Distribution Networks and enables them to deliver high quality content within their current infrastructure while pushing the bounds of modern web experience delivery.

Increased caching performance and resilience with Varnish High Availability
Varnish High Availability is a high performance content replicator that eliminates cache misses (when an item looked up in the cache is not found) and ensures the stability of the Varnish Cache set-up. By protecting the backend infrastructure from overload caused by cache misses, it increases website performance and minimizes the risk of frustrated visitors leaving websites. Varnish High Availability is for Varnish Cache users whose sites are business-critical. It can be installed with any multi-cache Varnish Cache setup, including two/three node CDN POP installations.

Customized cache optimization with Varnish Tuner
Varnish Tuner automates customized cache optimization in both the Varnish and operating system environments. It recommends configuration options for the Varnish Cache set-up including how the operating system should be tuned, which cache parameters should be changed or replaced and also explains these recommendations. Varnish Tuner makes it possible for businesses to find the specific set-ups that best matches their resources and needs, resulting in better website performance.

Availability:
Varnish Massive Storage Engine, Varnish High Availability and Varnish Tuner are all available from today with a Varnish Plus subscription
