# Incorporating keep into an existing deploy setup Concrete, by deploy *pattern* rather than by naming specific projects — the shape of the fit depends on how a project currently gets its config onto a target machine, not on what the project is. ## The general shape Wherever a deploy script or a manually-maintained `.env` exists today, the change is the same: replace "assume `.env` is already sitting there, hand-copied at some point" with a `keep pull` at the top of the script. ```bash # before — a deploy script assumes .env already exists on this machine set -euo pipefail source .env # or docker-compose reads it directly # after set -euo pipefail keep pull / --out .env ``` The one-time setup cost per machine: `keep identity init` once, send the printed public key to whoever runs `keep recipient add`, then `keep identity set-id ` with what comes back. After that, every future deploy from that machine just works — no more "wait, what's the DB password again" when setting up a new box. A deploy identity should almost always be granted **read-only** access (`keep grant --read-only`) — it only ever needs to `pull`, and a read-only grant means a compromised deploy box can't also rotate the vault or add itself more recipients. When you do the first `keep push` for a project, push the *real*, hand-maintained `.env` rather than a stripped-down one — any `# get this from X` / `# rotate quarterly` comments in it get preserved (values redacted) as a template alongside the secrets, retrievable later with `keep pull --template`. That's the one moment this context is available at all; a `.env` reconstructed later from memory won't have it. ## Getting the `keep` CLI onto a machine Chicken-and-egg: every pattern below assumes `keep` is already a runnable command on the machine doing the pulling. Two ways to get there, pick based on whether you're fine with a git checkout existing on that machine: **A machine you're already developing on, or don't mind cloning onto** (your laptop, a VPS you administer directly): ```bash git clone cd keep npm install ./scripts/install-cli.sh # builds, symlinks dist/cli/index.js onto PATH as `keep` ``` Symlinked rather than copied — a future `git pull && npm run build` is the entire upgrade story, no need to re-run the install script. **A deploy target you'd rather not clone a git repo onto** — bundle the CLI and ship it over SSH, the same way flit/waste-go's `deploy-*.sh` scripts ship a compiled binary: ```bash HOST=user@your-vps ./deploy-cli.sh ``` Not quite a single file: the bundle itself (esbuild, ~18kb) covers everything except `libsodium-wrappers`, which ships alongside it as the real, unmodified package (~1.6MB total with its own dependency, `libsodium`) rather than being force-inlined. That package's published ESM build follows a broken relative import (see `src/shared/crypto.ts`'s own comment on this), and statically inlining it via esbuild — technically possible by routing through a literal `require()` call instead of `import` — breaks its WASM engine's own Node-crypto feature detection at runtime ("No secure random number generator found"), confirmed by testing, not assumed. Shipping the real package is more reliable than fighting that. The script tars `dist-bundle/` (the esbuild output plus that one dependency) and extracts it to `~/.keep-cli/` on the target over SSH, then symlinks `~/bin/keep` to the entry point inside it — no git, no npm install on that machine at all, just a `node` runtime (already there, if it's running any of the other Node-based projects in this family). Re-run it any time the CLI changes; safe to overwrite. ## Pattern: several docker-compose projects on one or more VPSes The common shape once more than one or two projects are on `keep`: each project lives in its own directory on the VPS (`/opt/docker//docker-compose.yml`), and "deploy" means pulling that project's env and running `docker compose up -d` in its directory. `scripts/deploy.sh` in this repo is a small generic wrapper for exactly that: ```bash ./deploy.sh myapp # pulls myapp/production, runs compose in /opt/docker/myapp ./deploy.sh myapp staging # pulls myapp/staging instead DEPLOY_ROOT=/srv/apps ./deploy.sh myapp # different project root ``` One-time setup per VPS: `keep identity init` on that machine, register its public key with `keep recipient add`, `keep identity set-id`, then grant it **read-only** access to each project vault it deploys (`keep grant /production --read-only`). After that, `./deploy.sh ` is the whole deploy step — no `.env` hand-copied onto the box first. For "which machine can deploy which project," `keep overview` (admin) prints every vault and every recipient's access in one screen — the thing to reach for instead of checking each vault's grants one at a time. ## Pattern: docker-compose reading a local `.env` A common shape — `docker compose up -d` reads `environment:` values from a `.env` file sitting next to `docker-compose.yml` on the deploy machine, hand-maintained and containing real secrets. ```bash keep pull myapp/production --out .env docker compose up -d ``` No code changes needed in the target project — `keep` only changes *how the `.env` file gets there*, not what reads it. This is the easiest category to retrofit. ## Pattern: cross-compile + scp + SSH-restart deploy scripts A shape where a deploy script builds a binary locally, ships it to a VPS, and restarts a service over SSH — reading a local `.env` next to the script for things like shared secrets that shouldn't be hardcoded or re-typed on every invocation. ```bash keep pull myapp/production --out .env set -a && source .env && set +a # ...rest of the deploy script unchanged ``` Same retrofit as the docker-compose case, just applied before whatever build/ship step already exists. ## Pattern: a plaintext config file served to a browser Not every `config.js`/similar file that *looks* like environment config actually holds secrets — some of it is public-by-design (an API base URL, a feature flag) that's explicitly meant to be visible to anyone loading the page. `keep` solves a confidentiality problem; a file with nothing confidential in it doesn't have one. Worth checking this distinction before wiring `keep` into anything — retrofitting a non-secret config file would be solving a problem that file doesn't have. ## A vault server's own configuration Whatever runs `keep` itself needs its own `ADMIN_PASSWORD` to be a real, manually-set secret on its own host — it can't bootstrap its own trust root by pulling itself from itself. This is the same "root of trust starts somewhere unmanaged" fact every secrets system has (Vault's own unseal keys aren't stored in Vault either). Not a gap, just worth being explicit about: `keep`'s own deploy stays on a plain `.env`/ `docker-compose.yml` environment variables. ## New projects going forward The actual best use case isn't retrofitting existing deploys — it's never having the "hand-reconstruct a `.env` from memory" moment for a *new* deploy target in the first place. For whatever gets built next: register its production host as a `keep` recipient as part of first setup, write the deploy script to `keep pull` from day one, and the annoyance this was built to fix never has a chance to happen.
