Sending Slack alerts to approve CodePipeline deployments

At Resolver, we aim to automate as much of the boring technical jobs as possible, and that includes the whole continuous integration (CI) and deployment pipeline. We trigger these from GitHub, so a mere push or merge can kick-off our automated test suite or deploy to our staging environment for more automated and manual testing. […]

One of the tenets of modern framework-based web development is the management of your database state in code.

In addition, the desired state of […]

A beginner’s guide to Docker and containerisation

I joined Resolver in February 2020 and was put into the Accord team, working on a brand new project (they had literally typed the words ‘rails new’ the week before I joined). This meant I would be involved from the ground up, that I would see the app grow and develop from the very start, […]

The premise of the day is that it is our induction at a brand new start-up ‘Unicorn Rentals’, a fictitious company who dominate the Legendary Animal Rental Market (LARM) by providing […]

Granting time-limited access to assets in S3 using CloudFront

There was a time when asset storage was one of the problems facing web app developers – maybe you stored assets on the web server (easy if you only have one, more difficult if you need to sync them up between multiple servers), or maybe you had a shared disk mounted using NFS. In any […]

Making a Maker: a day in the life of a coding bootcamp student

A day at Makers was a lot like going to a theme park with your pals: The eager excitement of waking up and getting ready. Meeting your friends for breakfast, fueling up on coffee, and making all the best-laid plans for what is about to come. Enjoying all the sights and sounds of wonderment and […]
