crzy

Update your test environments in 3 seconds

working principle

crzy is mainly 2 things: (1) a GIT server that triggers a test, build and run on a receive; (2) an HTTP proxy that rollout the new version of your API.

a simple example

The best way to understand how it works is to use it. You can check go-crzy/color as an example. First install and run crzy:

go get github.com/go-crzy/crzy
crzy -server -repository color.git

Note: we assume you are working on the main branch, if that is not the case, add the -head flag with the name of your branch to the crzy command.

This commands above starts the GIT server that can be used to push you program to the http://localhost:8080/color.git URL. It also creates a proxy server on http://localhost:8081. You can then push your project the to crzy, with a simple git push command. Here is a complete example that includes the setup:

git clone https://github.com/go-crzy/color.git color
cd color
git remote add server http://localhost:8080/color.git
git push server

The API is now proxied and the next push will perform a blue/green update of your test environment...

the secret sauce

crzy is not magic and there is a few assumptions for your program to work with it:

• We depend on go and git on the server
• We assume your program is using Go and can be build from a simple go build on the root of your repository. You should rely on go mod
• We assume the program relies on HTTP and we can change its listening port with the PORT environment variable
• We are running the main branch of your project

crzy will be improved to manage broader use cases. If you like the idea, need support for another programming language or protocol or simply cannot figure out how to make it work, do not hesitate to open an issue.
