SSL with Docker Swarm, Let's Encrypt and Nginx

Currently with LE, you have to specify all the domains (including www) you want to include in the certificate which is really annoying. With wildcard certificates, this limitation will be gone and you'll be able to create one certificate for all the different subdomains. 🙌 Getting SSL to work with Docker and Let's Encrypt has been one of my short term goals recently. I started researching and found that there are some convoluted ways of doing it which involve tying in lots of other services into your stack which you don't need. 👎 I've found continue...

Rapid development with Node.js and Docker

The other day I had a ping on Twitter about the URL shortener I helped complete early this year, so I decided that now was the time to work out the best way to do it: @developius didn't you guys dockerize your URL shortener?maybe heptio can use it?— Leigh Capili (@capileigh) July 11, 2017 The service in question was built with Node and relied on MongoDB for storage. Seeing as the stack was so simple, I quickly wrote a Dockerfile and accompanying compose file so we could deploy the service continue...
