  Collection of tooling and automation to deploy IOHK infrastructure.
  
  ### Structure
  
  - `deployments` - includes all NixOps deployments controlled via `.hs` scripts
  - `modules` - NixOS modules
  - `lib.nix` - wraps upstream `<nixpkgs/lib.nix>` with our common functions
  - `scripts` - has bash scripts not converted to Haskell/Turtle into Cardano.hs yet
  - `default.nix` - is a collection of Haskell packages
  - `static` includes files using in deployments
  - `jobsets` is used by Hydra CI
  - `terraform` - other AWS infrastructure
  - `nix-darwin` - deployment script and configurations for MacOS X machines
  
  ### Getting SSH access
  
  1. Fork https://github.com/input-output-hk/iohk-ops
  2. Check out the `master` branch
  3. Add your username and SSH public key to the appropriate developer
     section of [`lib/ssh-keys.nix`](./lib/ssh-keys.nix). Keys should
     remain sorted alphabetically by username.
  4. Submit a PR against `master` and let DevOps know.
  5. Wait until the DevOps team deploys the infrastructure cluster.
  
  ## The `io` command
  
  Sources for the `iohk-ops` tool are in the [`iohk`](./iohk) directory.
  
  ### Usage
  
  After cloning this repo, start a `nix-shell`.
  
      % nix-shell
      [nix-shell:~/iohk/iohk-ops]$ io --help
  
  For more documentation, see [`docs/iohk-ops-reference.md`](./docs/iohk-ops-reference.md).
  
  ### Development
  
  To hack on the `iohk-ops` tool, use
  
      % nix-shell -A ioSelfBuild
      [nix-shell:~/iohk/iohk-ops]$ type io
      io is a function
      io ()
      {
          cabal exec iohk-ops -- "$@"
      }
      [nix-shell:~/iohk/iohk-ops]$ io --help
  
  This will provide a Haskell environment where you can use `io` to run
  the script or `ghci` for development:
  
      [nix-shell:~/iohk/iohk-ops]$ ghci -iiohk/common
      GHCi, version 8.2.2: http://www.haskell.org/ghc/  :? for help
      Loaded GHCi configuration from /home/rodney/config/.ghc/ghci.conf
      λ> :l iohk/iohk-ops.hs
  
  
  ### Run from anywhere
  
      $(nix-build --no-out-link https://github.com/input-output-hk/iohk-ops/archive/master.tar.gz -A iohk-ops)/bin/iohk-ops --help
