noconnorandClaude Opus 4.8 fdc3a71236 docker: install from the docker-ce repo on RHEL-family hosts
bootstrap failed outright on Oracle Linux: docker/install.sh piped
get.docker.com to sh, and that script allowlists distros by /etc/os-release
ID, so it aborted with "ERROR: Unsupported distribution 'ol'".

On a distro it does recognize, the convenience script only adds the repo and
installs the packages -- exactly what install_rhel() now does directly. Doing
it ourselves drops the allowlist, so every EL rebuild (Oracle, Rocky, Alma,
CentOS, RHEL) goes through one code path instead of needing to be enumerated.
Debian-family still uses get.docker.com. containerd.io needs --allowerasing to
replace the runc that Oracle Linux ships.

Also stop one failed module from killing the whole run: modules were bare
calls under `set -eu`, so docker/'s exit meant bin/, node/ and ansible/
silently never ran -- an unsupported distro string left the box with no CLIs,
no npx and no ansible. run_module warns and continues, then bootstrap exits
non-zero with a summary of what failed. Same guard 35befbe added for
individual tools in bin/install.sh, one level up.

# 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. The
managed rc sources `~/.zshrc.local` last for per-machine customizations
(see below).
- `git/` — sets git `user.name`/`user.email` and configures
`credential.helper store` (plaintext `~/.git-credentials`, 0600) for
HTTPS auth.
- `docker/` — installs full (rootful) Docker Engine from Docker's upstream
package repo (get.docker.com on Debian-family; the docker-ce repo wired up
directly on RHEL-family, since the convenience script rejects EL rebuilds
like Oracle Linux by name), enables the service (systemd hosts), and adds
the invoking user to the
`docker` group (takes effect at next login). No-ops where a rootless
Docker daemon is already running (e.g. Kasm) so it never fights that
setup. Uses sudo.
- `bin/` — installs userland devops CLIs as self-contained, statically
linked release binaries into `~/.local/bin`: jq, kubectl, helm, k9s,
kubectx/kubens, stern, yq, OpenTofu, terragrunt, task (go-task, the
Taskfile runner), the 1Password CLI `op` for secrets storage, the
opencode coding agent, zarf (DevSecOps for Offline and Airgapped
Kubernetes), and packer (HashiCorp's infrastructure build tool).
kind is installed only when full (non-rootless) Docker is available —
it doesn't work against rootless Docker, so it is skipped on Kasm.
No sudo, nothing outside `$HOME`, so tools persist across Kasm
redeploys with no reinstall. Idempotent: each tool records its version
under `~/.local/bin/.versions` and is skipped when the pinned version
is already present. `zsh/zshrc` puts `~/.local/bin` on `PATH`.
opencode is configured by `mcp-config/`: it points at the covert-gpt
LiteLLM gateway (`https://llm.covert-gpt.com/v1` for models,
`https://llm.covert-gpt.com/mcp` for MCP tools). Run
`mcp-config/install.sh` once to store your LiteLLM key and enable
config sync — without it, opencode installs but can't reach the
gateway.
- `ansible/` — installs Ansible into a virtualenv at `~/.local/opt/ansible`
(it's Python, not a single binary) and symlinks its CLIs into
`~/.local/bin`. Persists across redeploys; only rebuilt when the venv is
missing or broken. Building it may install `python3`/`python3-venv` via
the system package manager (the one place this module uses sudo).
- `docker-rootless-cgroup/` — on systemd-less hosts (e.g. Kasm), hand-delegates
cgroup v2 controllers to the rootless Docker daemon so per-container cgroups
work (rootless Docker otherwise comes up with
`CgroupDriver=none`). Uses sudo for host cgroup writes and restarts the
daemon; no-ops on systemd or non-rootless hosts. Re-run at each bootstrap
(the cgroup layout resets on redeploy); its PATH shim lives in `$HOME`.
- `mcp-config/` — shared MCP gateway config sync for laptops (LiteLLM /
opencode). Independent of `bootstrap.sh`; see its own README.
## Per-machine customizations and secrets
`~/.zshrc` is managed — bootstrap overwrites it, so never hand-edit it.
Per-machine settings and secrets go in `~/.zshrc.local`, which the managed
rc sources last (so it can override anything) and bootstrap never touches:
```sh
cp zsh/zshrc.local.example ~/.zshrc.local && chmod 600 ~/.zshrc.local
```
Variables modules look for:
- `GITEA_KEY` — personal access token for `git.nic-oconnor.com` (API/CLI
use; HTTPS git auth itself goes through `git/`'s credential helper).
- `LITELLM_KEY` — covert-gpt gateway key used by opencode. Normally you
don't set this by hand: run `mcp-config/install.sh` once and its shell
hook exports it from `~/.config/mcp-sync/key`. Set it in `~/.zshrc.local`
only on a box without mcp-sync.
- `OP_SERVICE_ACCOUNT_TOKEN` — 1Password service-account token for
non-interactive `op read` / `op run`.
- `GITEA_KEY`, `PROXMOX_MCP_TOKEN_ID`, `PROXMOX_MCP_TOKEN_SECRET` — **your own**
credentials for the client-side MCP servers in `mcp-config/`. opencode reads
them from your environment (`{env:VAR}`) and passes them to the MCP server it
spawns, so the tools act as *you*. Keep them in `~/.zshrc.local`; they are
never written into any config file.
These are NOT used by `ai-k8s-iac` / `task up`: the LiteLLM gateway hosts no
MCP servers and stores no MCP credentials. See `mcp-config/README.md`.
Secrets never go in this repo or in `zsh/zshrc` — that file is shared
config applied to every box.
`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.
