Compile terraform from source in the docker container

In an effort to always keep the version of terraform in the Dockerfile up to date, I would like to switch from using the precompiled binaries to compiling from source.

Sounds like the worst idea ever, to be honest. You are likely to run into all sorts of issues with this if it's used in production sort of environment. Best to have a CI system that uploads tested binaries to some reliable place.

Thanks for your input. The docker container is simply a means to test terraform without having it installed locally and allow me to use the latest enhancements before a new version is cut. If you are looking for a stable binary they are already provided by the terraform project. Also I don't know if I would reccomend using tech demo code for an alpha application in production.

That being said, personally I would put the CI enviornment after the creation of the Dockerfile and have the Dockerfile compile the code from scratch each time. Then the container can be tested as a whole unit instead. This ensures that terraform will operate the same way regardless of where it is deployed as it is being run in an encapsulated enviornment.

Looks like https://github.com/uzyexe/dockerfile-terraform is already fulfilling this need. I'll write a simple bash script around this container instead possibly checking to see if terraform is already installed locally first.
