I've been working on Athens for well over a year now, and I've mentioned before that I have been running the
athens.azurefd.net server on my own for almost all that time. The infrastructure that powered that server looked like this:
you ---> Azure Front Door | | | ACI Running Athens | | | Azure Cosmos DB
If you're not familiar with the acronyms, here are some short explanations for you:
It's important to note that Athens can run anywhere. I work for Microsoft so I chose to run it on Azure infrastructure and with CosmosDB as the database. I might consider moving to using Azure blob store later.
When I set up this public proxy, I wanted to give anyone interested an opportunity to try Athens without installing anything. I think it did exactly that, and it turns out the proxy also got Gophers to start thinking about modules and get their local environment set up.
This deployment was the first of its kind, too! I had no intention of making it "production ready" though. My goal was to encourage teams and companies to roll out their own hosted servers, so the Athens team could focus more on empowering teams to run their own internal Athens servers. I needed a deployment that would mostly run itself.
Those above technologies let me build an architecture that took care of mostly that. Most of the work I had to put into this deployment was managing the transition from Go 1.11 to 1.12 and then to 1.13.
I generally spend no more than an hour a week taking care of this infrastructure, and I've talked to a nontrivial amount of folks using
athens.azurefd.net in their production CI/CD pipelines. That's a testament to how well this architecture worked over time.
These days, there are three good proxies that I know of which are public and mostly production ready proxy. In theory, my deployment isn't really necessary anymore. That being said, I firmly believe that Athens needs to live on the public internet as a testbed for our software.
I still won't commit to it being production ready, so use it at your own risk (I'm sure some folks will!) But it's not going anywhere.
Not only is it going to stick around for testing, I'm also going to use the infrastructure as an educational tool. Instead of running Athens on ACI, I'll be moving the hosting infrastructure to Kubernetes. This move will open up a lot of flexibility in how I run, debug and deploy the service. Here's a high level diagram for what I'm planning to do:
you ---> Azure Front Door | | | Kubernetes ingress controller in AKS ---> Athens deployment (pods) | | CosmosDB
And here are some things you don't see:
/latestAPI calls for each module
I've already gotten started. In fact, you can see a running prototype of an AKS-backed Athens at k8s.goreg.dev. It's missing a lot of the features in that above list, but it's built approximately the same as the architecture in that diagram above.
All the code to do all of this is open source, and this is post #1 of a series that I'll use to chronicle my experience setting up and running Athens.
See you soon!
