Cloudflare Argo Tunnel with Rust+Raspberry Pi

Cloudflare Argo Tunnel with Rust+Raspberry Pi

Yesterday Cloudflare launched Argo Tunnel. In the words of the product team:

Argo Tunnel exposes applications running on your local web server, on any network with an Internet connection, without adding DNS records or configuring a firewall or router. It just works.

Once I grokked this, the first thing that came to mind was that I could actually use one of my Raspberry Pi's sitting around to serve a website, without:

  • A flaky DDNS running on my router
  • Exposing my home network to the world
  • A cloud VM

Ooooh... so exciting.

The Rig

I'll assume you already have a Raspberry Pi with Raspbian on it.

Plug the Pi into your router. It should now have an IP address. Look that up in your router’s admin UI:

OK, that's promising. Let's connect to that IP using the default pi/raspberry credentials:

$ ssh 192.168.8.26 -l pi

Stuffing the Camel into the Bikeshed

I’m sure that there are folk who believe that bodies like the IETF can exercise just the right level of restraint and process management to keep excessive levels of both camelling and bikeshedding out of the IETF and its Working Groups activities. Speaking personally, I just can’t see that happening.

Video Series: Modernizing Java Apps for Developers Part 4

Java Apps

Moving a monolithic application to a modern cloud architecture can be difficult and often result in a greenfield development effort. However, it is possible to move towards a cloud architecture using Docker Enterprise Edition (EE)  with no code changes and gain portability, security and efficiency in the process.

Java Apps

Part 4 takes advantage of the messaging service I added in part 3. In this installment, I’ll add self service analytics powered by the open source Elasticsearch / Kibana stack. The reporting database and analytics UI run in containers and the worker is updated to also store data in Elasticsearch. The Docker platform supports adding new components to a running deployment without shutting down the application containers that are currently running. You’ll learn how Docker lets you add new capabilities to the application with zero downtime in production.

Juniper JET & Golang

Network programmability and network automation go hand-in-hand (pun intended) and I’ve been waiting for an opportunity to play with the Juniper IDL (.proto) files to build a JET (Juniper Extension Toolkit) application. Thanks to Marcel Wiget’s efforts, the opening I’ve been waiting for came along!

So what is JET?

JET is a couple of things:

  • Ability to run Python, C and C++ applications onboard both veriexec and non-veriexec enabled Junos
  • Ability to create an off-box application using GRPC and MQTT

JET allows you to program Junos out of the normal NETCONF, CLI, SNMP and ephemeral DB methods that we’re all fairly used to. The other thing is, it’s quick. Like really quick. With GRPC and MQTT, we can program a network element using mechanisms the software world is used to. I’ve been saying for a long time our data is no longer our own and JET allows us to bridge organisational worlds in multiple ways. Pretty cool.

So what did you do?

Not having a huge amount of time for this, I opted for off-box and took Marcel’s code as the base for how to use the APIs exposed via GRPC.

The application uses the “bgp_route_service” JET API Continue reading

On the ‘net: Openness and Composable Systems

Openness, it seems, is “in the air.” While the Liqid folks were over at OCP, I was over at the Open Networking Summit (ONS), where I (primarily) attended the Linux Foundation (Networking), or LF(N), board meeting. What was interesting at this year’s summit is just how little the focus of open network is on bare metal routers and switches, and how much of the focus is on server-based and overlay networking. @GestaltIT

MapD Fires Up GPU Cloud Service

In the long run, provided there are enough API pipes into the code, software as a service might be the most popular way to consume applications and systems software for all but the largest organizations that are running at such a scale that they can command almost as good prices for components as the public cloud intermediaries. The hassle of setting up and managing complex code is in a lot of cases larger than the volume pricing benefits of do it yourself. The difference can be a profit margin for both cloud builders and the software companies that peddle their …

IDG Contributor Network: Bringing your Internet of Things infrastructure into the digital age

When Campofrio Food Group’s 17-year-old factory in Burgos, Spain, famously burned to the ground, the multinational meat processor turned tragedy into opportunity. With an eye on digital transformation, Campofrio rebuilt the facility as a connected factory, powered by the Internet of Things (IoT). This allowed the state-of-the-art, greenfield meat packing plant to automate processes and provide real-time data on materials, equipment and workers to uncover new business value.Such “blank canvas” opportunities to bring a factory into the digital age from the ground up don’t happen very often. Most IoT projects are implemented in existing, brownfield environments with traditional legacy systems, requiring an incremental approach. The goal of these gradual integrations has been to optimize or automate processes, gain some efficiencies, and move onto the next low-hanging fruit. But, this approach will not work if businesses want to capture IoT’s true transformational value: the creation of new business models, new revenue streams, new products and new markets.To read this article in full, please click here
