[DEVOPS-22-165] Switch to Nix for cardano-sl build used for genesis generation

[deepfire]

We are slowly switching all deployment-related operations to operate from an environment established by nix-shell entered in iohk-nixops.

This is a part of this unification process, and it makes the genesis generation script use Nix to provide the cardano-sl build.

This makes the routine cd pkgs; ./generate.sh invocation (inside iohk-nixops) a prerequisite for genesis itself -- but this already is a prerequisite for deployment anyway.

Purely dev-based scenarios will change, though.

@deepfire, thanks for your PR! By analyzing the history of the files in this pull request, we identified @georgeee and @denisshevchenko to be potential reviewers.

This script should really be refactored and part of iohk-nixops I think.

But for now we can use this change with nix-shell.

@deepfire CI is failing

[deepfire]

@domenkozar, the errors were transient, network-related -- restarting helped

[deepfire]

@domenkozar, the CI passed -- a simple restart helped

[deepfire]

@domenkozar, can you think of any further actions we need here?

[domenkozar]

yes, this has to wait until we have stack2nix based PRs as currently stack is the tool for building cardano-sl.

I changed base branch to cardano-sl-0.5. It shouldn't change anything. cardano-sl-0.5-rc will be removed.

[georgeee]

yes, this has to wait until we have stack2nix based PRs as currently stack is the tool for building cardano-sl.

Agrees

[georgeee]

This PR should wait till nix is used as primary development tool for building things

Ping all

Is it obsolete now?

[domenkozar]

@georgeee Is scripts/generate/genesis.sh obsolete now? If so, we can close this.

[deepfire]

Closing as obsolete.
