What is freeholdy

freeholdy is a single-VPS orchestrator for your Docker apps. It puts every project behind nginx + Let's Encrypt and serves each one at its own {name}.your_domain.com subdomain — with HTTPS wired up automatically.

You push code (a folder, a git URL, or a pre-packaged plugin); freeholdy auto-detects whether it's a single-container Dockerfile project or a multi-container docker-compose.yml stack (compose wins when both are present), builds it, runs it, and wires up the reverse proxy and SSL certificate. No per-project nginx or certbot configuration to write.

There are three ways to drive it:

• CLI — fhcli, a small command-line client (used in the examples below).
• Web UI — a control panel at ui.<your-domain> covering the same operations in the browser.
• REST API — everything above is a thin client over the API at api.<your-domain>, authenticated with a bearer token.

Installation

Prerequisites

• A fresh Ubuntu VPS with root access. The installer handles all packages itself.
• A base domain with a wildcard DNS record (*.your_domain.com) pointing at the server — projects are served at {name}.your_domain.com and the API at api.your_domain.com.

One-command bootstrap

bash <(curl -fsSL https://raw.githubusercontent.com/aafanasev-dev/freeholdy/main/install.sh)

On a server that already runs other apps, clone the repo and run sudo bash install.sh instead. The installer auto-detects one of two modes and asks you to confirm before touching anything:

• FRESH — docker and/or nginx are missing → it installs what's missing. For a dedicated or empty VPS.
• COEXIST — both are already present → it never installs, restarts, or upgrades docker or nginx, and aborts early if your existing nginx config is broken. Safe next to other apps.

The installer then:

1. Prompts for a service user (default freeholdy), your base domain, and a Let's Encrypt email.
2. Sets up the service user with docker access and passwordless nginx/certbot sudo.
3. Runs configure.sh to build the Python venv (one venv serves the server and the CLI), writes .env, and picks a free local API port.
4. Adds the api.<domain> nginx vhost, obtains its SSL certificate, and installs a nightly renewal cron.
5. Installs and starts the freeholdy systemd service.
6. Prints your first API token — shown once; save it.

Flags: -u USER (service user), -y (assume yes), -r (redo every step). Progress is tracked in install.log, so re-running is idempotent — it skips finished steps and can, for example, re-enable SSL after DNS propagates.

Set up the CLI

The CLI shares the project's single venv — there is no separate one under cli/. On your workstation, from a clone of the repo:

bash configure.sh              # builds ./venv (server + CLI deps)
cp cli/.env.example cli/.env   # set TOKEN and BASE_DOMAIN

See The Python environment for what configure.sh does and its flags.

Check it works with ./cli/fhcli.py health — no source venv/bin/activate needed, because fhcli.py re-execs itself under ./venv/bin/python. On the server the installer has already done this and linked fhcli into /usr/local/bin, so you can just run fhcli health.

The same token logs you into the web UI at ui.<your-domain> — it is stored in the browser and sent as a bearer token on every request.

Updating freeholdy

install.sh is a bootstrap, not an upgrader — it records finished steps in install.log and skips them on a re-run, so running it again never pulls new code. update.sh is the supported way to move an installed server to a newer revision.

sudo bash update.sh

Picking a version

It fetches from origin and lists what you can move to: the main branch plus every release tag, each shown with the version it declares in version.json and its latest commit. The revision you are currently on is marked (current).

   1) main               v0.11.4     0bcc32c   Updating help plugin (current)
   2) v0.11.0            v0.11.0     2eb9030   Env variables handling

  ?  Which version? [1]:

Use -l to see that list and exit without changing anything, or -v REF to name a revision up front and skip the prompt. After you choose, it prints exactly what it is about to do and asks once more — nothing on the server changes until you confirm.

What it does

1. Removes the webui and freeholdy-help projects, if they are installed. They are rebuilt in step 7 — that is how the new code reaches them.
2. Stops the freeholdy service.
3. Hard-resets the checkout to the revision you chose.
4. Runs configure.sh to bring the Python environment up to date.
5. Backs up data/freeholdy.db, then runs migrate_db.sh.
6. Starts the service again and waits for /health to answer.
7. Re-adds the plugins it removed, waiting for each container build to finish.

What survives

Everything covered by .gitignore is kept — the reset never passes clean -x. That means .env, data/ (your database), projects/, dockerfiles/, compose/, nginx_configs/, cli/.env and venv/ all stay as they are. Your deployed projects and their containers are never touched — only freeholdy itself is updated.

Existing API tokens keep working, so your web UI login link stays valid. update.sh mints a temporary token for its own API calls and revokes it when it exits, leaving no new credential behind.

If it fails

Nothing is changed before you confirm, and any failure up to the moment the service stops leaves the server exactly as it was. Past that point the script prints the path of the database backup it took, the revision you were on, and the commands to put both back:

sudo -u freeholdy git -C /home/freeholdy/freeholdy reset --hard <previous-rev>
cp <backup> /home/freeholdy/freeholdy/data/freeholdy.db
sudo systemctl start freeholdy

The Python environment

configure.sh owns the project's single virtualenv at venv/. One environment serves both the API server and fhcli — the CLI re-execs itself under venv/bin/python, so it needs no source venv/bin/activate.

bash configure.sh

Re-running it is cheap: it stores a hash of requirements.txt inside the venv and skips the install while that hash still matches. That is why update.sh can call it every time — the work only happens when the dependencies actually changed. It also rebuilds the venv from scratch if the Python interpreter it was built with is no longer the one on PATH.

It runs as whoever invokes it — only the python3.X-venv package fallback needs sudo. On a server the installer already ran it as the service user.

Deploying apps

There is no separate "create project" step — the first deploy creates the project, and re-running the same deploy redeploys it. Every deploy streams its build log live to your terminal.

From a folder

fhcli deploy myapp ./myapp

Uploads the folder, auto-detects the manifest — a Dockerfile (it must EXPOSE a port) or a docker-compose.yml — builds it, runs it, and wires up nginx + SSL at myapp.your_domain.com. Compose stacks get one subdomain per exposed service ({service}.myapp.your_domain.com). Re-run the command to redeploy.

Add --env .env to store the project's environment variables before the container first starts.

From git

fhcli deploy mysite https://github.com/owner/repo.git
fhcli deploy mysite git@github.com:owner/repo.git --branch dev

Clones the repo on the server and runs the exact same detect → build → run → nginx pipeline. Re-run to redeploy the latest commit.

For private repos, run fhcli get-git-key — it prints the server's SSH public key (generated on first use); add it as a deploy key on the repo, then deploy over the git@… URL.

From plugins

fhcli plugins                       # list available plugins
fhcli plugin-add nextcloud mycloud  # install one as project "mycloud"

Plugins are pre-packaged apps that deploy through the same pipeline. Some are interactive: the install prompts you right in the terminal (e.g. to choose an admin account) before the build starts. If your terminal disconnects mid-install, re-running plugin-add resumes it.

Plugin catalog

Versions & rollback

Every deploy creates a new version, and the previous ones are kept so you can go back. The new version is built and verified before traffic moves to it, so a failed build never takes the live site down.

fhcli versions myapp            # list versions: active / inactive / archived
fhcli rollback myapp 2          # make version 2 live again
fhcli set-backup-limit myapp 3  # keep at most 3 archived versions

How a deploy switches over

Single-container projects are true blue/green. Version N is built as its own image and started in its own container on its own local port, next to the one still serving. Only once the build succeeds and the new container is confirmed running does nginx get re-pointed at the new port — a one-line change and a reload. If the build fails, nothing was touched.

Compose stacks are build-first with a brief switch. Running two copies of a stack side by side isn't possible in general — services bind host ports themselves, some use host networking, and named volumes are shared. So freeholdy builds and pulls while the old stack keeps serving, tags every resulting image as version N, and only then does a short down + up. The images are already on disk, so the gap is seconds. A failed build or pull never reaches that point.

What the three states mean

• active — the running version nginx points at.
• inactive — the version you just replaced, kept as a stopped container for an instant rollback. Single-container projects only — bringing a compose stack down removes its containers, so compose versions go straight to archived.
• archived — older versions whose images (and, for compose, a snapshot of the project files) are retained, but whose containers are gone and whose ports are freed. Capped by the backup limit — default 5, oldest pruned first after a successful deploy.

What a rollback restores

A rollback puts back code and images. For a single-container project the container is recreated from that version's image rather than just restarted — which is what lets a rollback pick up the project's current environment variables. For a compose stack, freeholdy restores the snapshot of the project files, re-wires nginx (custom domains and plugin subdomains are preserved), and brings the stack up on the retained version tags.

Rollbacks stream their log over the same channel as a deploy, so fhcli rollback shows you exactly what is happening.

Environment variables

freeholdy stores a .env file per project on the server and injects it every time a container is created. Nothing is baked into the image, and the values live outside the project directory — so a git redeploy or a rollback can't wipe them.

Scopes

Each project has a project-level file. For a single-container project that file is the container's environment. For a compose stack it is shared by every service — and each service may additionally have its own file, whose values win over the shared ones.

fhcli env-set myapp .env               # the project-level file
fhcli env-set mystack db.env -s db     # one service (wins over the shared file)

fhcli env-get myapp                    # print it
fhcli env-get myapp > .env             # …or save it
fhcli env-clear myapp                  # delete it

The format is ordinary dotenv — comments, blank lines, an export prefix, and single- or double-quoted values are all accepted, and the file is stored exactly as you wrote it. A malformed key or a value split across lines is rejected with the line number, rather than quietly producing a container with a broken environment.

Applying changes

fhcli restart myapp

restart recreates the container(s) from the images they are already running: no rebuild, no new version, just a fresh container with the current environment. For a compose project only the services whose environment actually changed are recreated. Until you do it, freeholdy reports the stored file as not applied — the CLI prints a hint and the web UI shows a "restart to apply" banner.

The first start

Because setting variables never starts anything, a project that is deployed before its .env exists boots without one. To have the values in place for the very first container, send them along with the deploy:

fhcli deploy myapp ./myapp --env .env
fhcli deploy mysite https://github.com/owner/repo.git --env .env
cat .env | fhcli deploy myapp ./myapp --env -

The web UI's deploy form has the same box. Leaving it blank on a redeploy keeps whatever is already stored — it never silently wipes a project's environment. Clearing is always explicit (fhcli env-clear).

freeholdy never hands your values back out in listings: the project list carries only a count, and reading a file is a deliberate, separate request.

Logs & shell

Container logs

fhcli logs myapp                # last 200 lines
fhcli logs myapp -n 50
fhcli logs mystack -s api       # one compose service
fhcli logs myapp | grep -i error

This is what your app printed — the container's own stdout and stderr. For a compose project you get the whole stack interleaved and prefixed with the service name; -s narrows it to one service. It's a snapshot rather than a live follow, and it goes to stdout, so it pipes and redirects cleanly.

Not to be confused with fhcli status myapp, which shows the log of the last freeholdy operation — the build, the run, the stop. When a deploy fails, read status; when the app misbehaves after starting, read logs.

Interactive shell

fhcli exec myapp                        # a shell in the container
fhcli exec myapp "python manage.py shell"
fhcli exec mystack -s api               # one compose service

A real terminal over a WebSocket — a full TTY, so editors, colours, and interactive prompts all work as they would over SSH. The web UI offers the same shell in the browser.

API

The CLI, the web UI, and the fhdeploy skill are all thin clients over one REST API at https://api.<your-domain>. Anything they can do is scriptable — from CI, a cron job, or your own dashboard.

• Auth — every endpoint takes Authorization: Bearer <token>, except /health, /version, and /docs.
• Interactive reference — the OpenAPI explorer is live at https://api.<your-domain>/docs, with every request and response schema.
• Long jobs return immediately — builds, deploys, rollbacks, and plugin installs respond with a ws_path; the log streams over that WebSocket.

TOKEN=your_token_here
BASE=https://api.your_domain.com

# Deploy a folder — auto-creates the project, detects the Dockerfile or
# docker-compose.yml, builds, runs, and wires up nginx + SSL.
curl -X POST "$BASE/projects/myapp/upload" \
  -H "Authorization: Bearer $TOKEN" \
  -F "files=@./Dockerfile;filename=Dockerfile" \
  -F "files=@./app.py;filename=app.py"

# ...or deploy straight from git (idempotent: same name = redeploy).
curl -X POST "$BASE/git/add" \
  -H "Authorization: Bearer $TOKEN" -H "Content-Type: application/json" \
  -d '{"name":"mysite","git_url":"https://github.com/owner/repo.git"}'

curl "$BASE/projects/myapp/status" -H "Authorization: Bearer $TOKEN"

Endpoints

There is no create endpoint and no separate build or start call — a deploy does all of it, and re-deploying is how you ship an update.

Streaming logs

Browsers can't set an Authorization header on a WebSocket, so every freeholdy socket opens the same way: your first frame must be {"type":"auth","token":"…"}. The server replies {"type":"ready"}, streams {"type":"stdout","data":"…"} frames, and finishes with {"type":"exit","code":N}. Shell sockets also accept stdin and resize frames from the client.

Close codes: 4401 auth failed, 4404 not found, 4409 busy. Disconnecting never kills a build — the job keeps running on the server, and reconnecting re-streams it.

Tokens

Tokens are minted on the server, from the repo root with the venv active:

python scripts/generate_token.py generate --name "ci"
python scripts/generate_token.py list
python scripts/generate_token.py revoke --id 3

CLI reference

Every fhcli command, and what it maps to. Any of them takes --help for its full options and examples.

AI integration

freeholdy ships a Claude Code skill, fhdeploy, that lets Claude deploy to your server for you — no fhcli required. It talks to the REST API directly: uploads a folder (or points the server at a git URL), follows the build, and reports the live endpoints.

Setup

1. Copy skills/fhdeploy/ from the freeholdy repo into your Claude Code skills directory (e.g. ~/.claude/skills/).
2. Run it from any Claude Code session:

   /fhdeploy myapp ./myapp
   /fhdeploy mysite https://github.com/owner/repo.git

3. On first use it asks for your API token (printed by the installer) and base domain, and remembers them in Claude Code memory for next time.

Beyond deploys, the skill knows the versioning API — it can list a project's versions and roll back — and the git deploy-key flow for private repos. In practice: tell Claude to build something, then tell it to ship it.
