# dotfiles

Configures fresh VMs (RHEL-family or Debian-family) with a consistent
environment. Run `./bootstrap.sh` (or curl-pipe it) to apply everything;
each module also runs standalone and is safe to re-run.

## Quick start

On a fresh box, apply everything with one command:

```sh
curl -fsSL https://git.nic-oconnor.com/public/dotfiles/raw/branch/main/bootstrap.sh | sh
```

When piped like this (no local checkout), `bootstrap.sh` clones the repo to
`~/.dotfiles` and runs from there, so `git` must be installed first. Re-running
the command updates the checkout (`git pull`) and re-applies every module.
Override the destination or source with `DOTFILES_DIR` / `DOTFILES_REPO`.

Already have a clone? Just run it directly:

```sh
./bootstrap.sh
```

## Modules

- `zsh/` — installs zsh + oh-my-zsh, drops a managed `~/.zshrc`
  (robbyrussell theme, git plugin), and sets zsh as the login shell.
- `git/` — sets git `user.name`/`user.email` and configures
  `credential.helper store` (plaintext `~/.git-credentials`, 0600) for
  HTTPS auth.
- `bin/` — installs userland devops CLIs (jq, kubectl, helm, k9s,
  kubectx/kubens, stern, yq, OpenTofu, terragrunt, plus kind when rootless
  Docker is available) as self-contained,
  statically linked release binaries into `~/.local/bin`. No sudo, nothing
  outside `$HOME`, so they persist across Kasm redeploys with no reinstall.
  Idempotent: each tool records its version under `~/.local/bin/.versions`
  and is skipped when the pinned version is already present. `zsh/zshrc`
  puts `~/.local/bin` on `PATH`.
- `ansible/` — installs Ansible into a virtualenv at `~/.local/opt/ansible`
  (it's Python, not a single binary) and symlinks its CLIs into
  `~/.local/bin`. Persists across redeploys; only rebuilt when the venv is
  missing or broken. Building it may install `python3`/`python3-venv` via
  the system package manager (the one place this module uses sudo).
- `docker-rootless-cgroup/` — on systemd-less hosts (e.g. Kasm), hand-delegates
  cgroup v2 controllers to the rootless Docker daemon so per-container cgroups
  work and `kind` can create clusters (rootless Docker otherwise comes up with
  `CgroupDriver=none`). Uses sudo for host cgroup writes and restarts the
  daemon; no-ops on systemd or non-rootless hosts. Re-run at each bootstrap
  (the cgroup layout resets on redeploy); its PATH shim lives in `$HOME`.
- `mcp-config/` — shared MCP gateway config sync for laptops (LiteLLM /
  opencode). Independent of `bootstrap.sh`; see its own README.

`lib/os-detect.sh` provides shared package-manager detection (`dnf`/`yum`
vs `apt`); `lib/fetch.sh` provides arch detection and binary-download
helpers. Both are used by module install scripts.
