Pullbase: GitOps for Linux Servers

GitOps for Linux Servers — Manage packages, services, and configuration files using Git as your source of truth.

Pullbase brings Argo CD-style GitOps workflows to traditional servers (VMs, bare-metal). Define your desired server state in YAML, commit to Git, and let Pullbase agents keep your fleet in sync.

Managing configurations across fleets of non-Kubernetes servers often means manual SSH sessions, complex push-based tools, or fragile scripts. This leads to configuration drift, inconsistency, and operational overhead.

Pullbase solves this with:

• Git as Source of Truth — Define packages, services, and files in YAML. Git history is your audit trail.
• Pull-Based Model — Lightweight agents fetch and apply configurations. No inbound SSH required.
• Automatic Drift Detection — Agents continuously compare actual vs. desired state and auto-reconcile.
• One-Click Rollbacks — Point to any previous commit and agents revert automatically.

docker compose exec pullbase pullbasectl auth bootstrap-admin \

Open http://localhost:8080 and sign in with your admin credentials.

1. Create an Environment (links to your Git config repo)
2. Create a Server and generate an agent token
3. Run the install script on your target server:

curl -fsSL "https://your-pullbase-host/api/v1/servers/web-01/install-script?token=pbt_xxx" | sudo bash

The agent installs as a systemd service and starts reporting status immediately.

Your Git repository defines the desired state. Create a config.yaml:

serverMetadata:
  name: web-01
  environment: production

packages:
  - name: nginx
    state: latest
  - name: curl
    state: present

services:
  - name: nginx
    enabled: true
    state: running

files:
  - path: /etc/nginx/nginx.conf
    content: |
      user nginx;
      worker_processes auto;
      events { worker_connections 1024; }
      http {
        server {
          listen 80;
          location / { return 200 'Hello from Pullbase'; }
        }
      }
    mode: "0644"
    reloadService: nginx

Commit this to your repo, create an environment pointing to it, and agents will apply the configuration.
