This repository is a Nix flake containing tools needed as an OpenShift Dedicated SRE. This workflow allows standard tooling and versions to be available while on-call without forcing these to clash with other versions that are installed.
- Nix package manager
- direnv (recommended, but optional)
- Note that after installation, e.g.
brew install direnv, it needs to be hooked into the shell
- Note that after installation, e.g.
-
Clone this repo and change directory in
git clone https://github.com/mjlshen/osd-nix.git cd osd-nix -
If direnv has been installed, an error like the following will appear:
direnv: error /path/to/osd-nix/.envrc is blocked. Run `direnv allow` to approve its contentRunning
direnv allowwill load the packages defined in this flake into your path while inside this directory. The first time, this compiles many of the packages from source, so it can take some time - afterwards it's instantaneous. -
Without direnv, a temporary shell can be started containing all the packages defined by this flake with
nix develop
Like when using direnv, the very first time
nix developis run, many of the packages are compiled from source, so it can take some time. -
All available packages can be found in nix/openshift-sre.nix with all other custom packages contained inside the nix folder. Other packages that are otherwise installed remain in your path.
Mostly novelty...
but if it catches on it's a really convenient way for a cross-platform, hermetic, and standardized environment. Notably for macOS users, it would eliminate the necessity to mount local directories into containers to run like boilerplate or ocm-container if Nix flakes were provided in each repo. That way, anytime a contributor updates a package in the flake, it's fixed immediately for all other contributors without a dependency on locally installed packages!
