This repository provides a couple things:
These are premade environments that provide all the software used in CS classes. On the CS department machines, you can access them via
nix develop polytopia#cs221On your own machine (if Nix is installed), you can access them via
nix develop github:Samasaur1/polytopia#cs384At the time of writing, there are three dev shells:
- cs221
- cs378
- cs384
You can check the dev shells that exist now either by looking in the devShells directory or running nix flake show polytopia.
nix flake update --commit-lock-fileThere is a GitHub Action set up that automatically updates the flake inputs weekly, so the only action necessary is to merge this PR.
Perhaps we only want to update dev shells in between semesters, so that they are consistent throughout a class?
-
Install Ansible (you can launch a subshell that provides Ansible via
nix develop) -
Run the playbook
ansible-playbook -i inventory.ini playbook.yaml -K
If you're using the dev shell:
poly-run-ansible
Note that you need SSH host configurations for all machines, since they are defined in the inventory without their FQDNs
-
Generate a temporary password (let's say it's
correct horse battery staple) -
Install
mkpasswd(you can launch a subshell that providesmkpasswdvianix develop) -
Hash the temporary password:
mkpasswd --method=sha-512
If you're using the dev shell:
poly-hash-password
Using our example, this gives
$6$e0A7MR6aAnL3r9Y5$WevmaiUlUo6p67OErBd8.krTCTg/36EnNrpj8zUJKNWwIn3L7MqSmc3rOPupmajxJQ9z3N9Hsg7x9GaZfeVZr. -
