Here's what we are using to build Bullet Train, our Feature Flag platform. With some careful VPS purchases, most of this stuff can be run completely free of charge!
GitLab is pretty awesome, and it gets more awesome with every release. The big thing it has going for it is that it integrates a bunch of different tools, and makes them work together to help drive productivity. This also means that a single GitLab instance can manage a large part of the development process.
We self-host GitLab. It is a fairly big application so we're running on a 3GB VM on Google's Cloud Platform, but you could easily use a cheaper VPS provider if you wanted to. The open source version of GitLab is called their "Community Edition", but don't be fooled, it's fully featured and is only missing a couple of items from their paid product. It installs pretty easily via their Omnibus packages, and updating is pretty much just
apt-get update; apt-get upgrade
You can also use their hosted product as we do, it has a great free tier.
Well, yeah obviously. All our code is pushed to GitLab. Being open source and self-hosted there are no limits to the number of developers or private projects you can host.
GitLab has a first class CI/CD platform built in. You can get push-to-deploy working quickly and easily. There's only a couple of things you need to do to get up and running.
.gitlab-ci.ymlfile to the root path of your project. This file contains the commands you need to build your product.
We still think Trello is the best of the bunch. It's fast, simple and gets out of the way. Having said that, they have recently been making some changes to their free tier, and so the one other option that might be worth checking out is, again, back in Gitlab.
You can use the Gitlab issue tracker to manage requirements, and view them in a Kanban board, similar to Trello. A big advantage of doing this is, again, the tight integration between the Gitlab components. For example, if you push a commit with the message
Fixes #252, issue number 252 will be referenced by that commit. When you merge that commit into the master branch, Gitlab will even mark the issue as resolved! There's a bunch of other integrations that use this pattern.
We're using the amazing Dokku to run dev and feature branches. Dokku is an amazing bit of software that basically turns your VPS into a mini-Heroku platform. Its pretty simple to create and destroy feature branches, as well as build and deploy development builds. We use this Docker image to integrate Gitlab CI with Dokku.
This really depends on the application you are working on. For Bullet Train, our Feature Flag platform, we actually split out the hosting:
Well, we definitely use our Feature Flags to help build our Feature Flags! To ensure a smooth CI/CD process, and to reduce the amount of code that is committed but not deployed, we use our Bullet Train Feature Flags platform within Bullet Train itself. Meta. We have a decent free tier too, so we don't have to pay ourselves to run our feature flags.
For email, we're using the pretty awesome Migadu for inbound email, and SendGrid for our outbound email.
