TODO

This page describes steps to take to move toward initial valid commit.

  1. Make list of constituent repositories.
  2. Commit all pending work on constituent repositories.
  3. Freeze all constituent repositories.
  4. Import constituent repositories with Git history.
  5. Reorganize repositories.
  6. Document organization.
  7. Scan for secrets.
  8. Initial commit.
  9. Consolidate duplicated repos.
  10. Differentiate active and inactive projects
    1. homelab, projects, blog, archive
  11. Configure repo-level tools:
    1. .gitignore
    2. .gitmodules
    3. LICENSE
    4. .github/workflows
    5. .gitea/workflows
    6. .pre-commit-config.yaml
  12. Cutover hosts from homelab to Jafner.net with sparse checkout.
    1. fighter - Migrate secrets from ~/homelab/**/*_secrets.env to ~/Jafner.net/active projects/homelab/**/*_secrets.env.
      • cd /home/admin/homelab/ && SECRETFILES=$(find . -name '*_secrets.env' | cut -d'/' -f2-) && for file in $(echo $SECRETFILES); do FROM_FILE=$(echo "/home/admin/homelab/$file"); TO_FILE=$(echo "/home/admin/Jafner.net/homelab/$file"); echo "$FROM_FILE -> $TO_FILE"; cp -p "$FROM_FILE" "$TO_FILE"; done
    2. druid
  13. Pin docker image versions to current.
  14. Configure deployment systems
    1. Github Pages for Jafner.dev
    2. Push repo updates to fighter and druid
  15. Write README.md that maps constituent projects.
  16. Publish the repo.
  17. Archive/annotate all constituent repos to point to subpath of new repo.

Repositories

  1. homelab Gitea, Github (docker_config), Github (wiki), Github (cloud_tools), Github (self-hosting).
    • Rename? Jafner.net? Wouldn't that be Jafner/Jafner.net/Jafner.net?
  2. Jafner.dev Github.
  3. dotfiles Gitea, Github.
  4. nvgm Gitea
  5. pamidi Gitea, Github
  6. docker-llm-amd Gitea
  7. doradash Gitea
  8. clip-it-and-ship-it Gitea (PyClipIt), Github.
  9. razer battery led Github
  10. 5etools-docker Github
  11. jafner-homebrew Github

Import Repositories

Below are described the steps taken to merge the many repositories listed above into one.

  1. Install git-filter-repo: curl -o ~/.local/bin/git-filter-repo https://raw.githubusercontent.com/newren/git-filter-repo/main/git-filter-repo && chmod +x ~/.local/bin/git-filter-repo
  2. git clone ssh://git@gitea.jafner.tools:2225/Jafner/homelab.git && cd homelab
  3. git filter-repo --to-subdirectory-filter homelab
  4. Init a new empty git repository called Jafner.net: cd ~/Git/Jafner.net && git init
  5. mkdir homelab && cd homelab
  6. git remote add homelab ssh://git@gitea.jafner.tools:2225/Jafner/homelab.git
  7. git fetch homelab --tags
  8. git merge --allow-unrelated-histories homelab/main
  9. git remote remove homelab

That's obviously a lot of steps to handle each repo manually, so let's script it.

Scan for secrets

  1. Install pre-commit: pip install pre-commit
  2. Clone, build, install gitleaks: cd ~/Git && git clone https://github.com/gitleaks/gitleaks.git && cd gitleaks && make build && cp gitleaks ~/.local/bin/
  3. Create pre-commit config file.
  4. Update and install pre-commit hooks: pre-commit autoupdate && pre-commit install
  5. Generate baseline scan: gitleaks detect -v -r gitleaks-report.json

.pre-commit-config.yaml

repos:
-   repo: https://github.com/gitleaks/gitleaks
    rev: v8.18.4
    hooks:
    -  id: gitleaks
-   repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v2.3.0
    hooks:
    -   id: check-yaml

From there we evaluate the report and remediate. I got a list of files with secrets via cat gitleaks-report.json | jq -r 'keys[] as $k | "\($k), \(.[$k] | .File)"'

We can use git filter-repo again to erase mention of any files containing secrets.

git filter-repo --invert-paths --path <path/to/file/with/secret>
