Around this time, he also explained how he felt the documentation was disjointed and the messaging wasn’t clear about its unique selling points. He wanted to gain access to his Raspberry Pi cluster running ECS Anywhere, but he explained that performance was poor because the VPN software was locking up the CPU with interrupts. Inlets was a project that evolved into a product and over the two years, as new features were added, I wrote blog posts to explain how to use them. I used the chapter from my eBook Everyday Go as a starting point.Īdding metrics and observability support to inlets for customers to monitor their tunnels 1. One of my top five was adding the status command and Prometheus metrics. It doesn’t need any elevated privileges and is easy to automate because it runs in userspace and is self-contained within a single binary. Inlets is written in Go, which makes it easy to cross compile to various Operating Systems, CPUs and to package it in containers. A VPN wouldn’t work because of the corporate VPN’s restrictions.Īnd even if they would have worked, there were no container images available for them, and no Kubernetes integration.But my team needed webhooks, and more than that - they needed webhooks to a Kubernetes service, that they were developing locally. That’s the problem with a SaaS - because it uses a well-known domain, IT can just block it entirely.

Limited integration and options for automationįor me, in late 2018, I just needed a tunnel that would work on a corporate VPN and the best known developer tunnel was blocked by domain.

Limited documentation, lack of support or community.

You just can’t beat the convenience of typing in one command and having someone else do everything for you.Ī SaaS business model often has a low price point, but comes with trade-offs: Who needs a tunnel anyway?įor a very long time, I was able to get by with the limitations of SaaS-based tunnels, which were largely free or very low cost. These include a new business model, Prometheus monitoring and automated TLS with Let’s Encrypt for HTTPS tunnels. In this short article, I’ll cover the use-case and origin story for inlets before going on to cover highlights of the past year.

Did you know that Inlets was first released in January 2019? That means it’s coming up for its third birthday.
