• 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

The io command

Sources for the iohk-ops tool are in the 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.

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 -- "[email protected]"
}
[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
