Containr is an open-source control plane for Docker. Create a project, drop services onto a visual canvas, wire them together with environment variables, and deploy — no Kubernetes, no cloud bill. Services appear as nodes with auto-inferred connections; logs, metrics, builds, and rollbacks are one click away.

Features

Project canvas — visual service topology, groups, drag/drop, auto-inferred connections
Deployments & builds — Docker deploys with history, logs, rollback, live build status
Git integration — GitHub, GitLab, Bitbucket, Gitea; webhooks, GitHub App
Managed databases — one-click provisioning with backup/restore
Metrics — per-service Docker stats plus host CPU/memory/disk telemetry
Templates, cron, previews — service catalog, scheduled jobs, preview deploys
Auth & security — Better Auth sessions (email + OAuth), audit logs, vuln scans
Networking — Traefik reverse proxy, optional Cloudflare Tunnel

Quick Start

Requires Docker with the Compose plugin, openssl, and curl:

curl -fsSL https://raw.githubusercontent.com/Dvorinka/Containr/main/install.sh | bash

Installs into ./containr, generates secrets, pulls the published :latest images, and starts the stack — UI at http://localhost:3000, API at http://localhost:8082. Non-interactive; re-runs never overwrite .env.

Override with env vars:

curl -fsSL https://raw.githubusercontent.com/Dvorinka/Containr/main/install.sh | \
  HTTP_PORT=8080 CONTAINR_DIR=/opt/containr bash

CONTAINR_VERSION pins a release tag, CONTAINR_REF selects the git ref for downloaded files, CONTAINR_BUILD=1 builds from source. From a git checkout, ./install.sh installs in place; plain docker compose up -d pulls the same images (--build to compile locally).

Local development and self-hosted deployment (Traefik + Cloudflare Tunnel): see docs/guides/ and infra/docker-compose.yml.

Architecture

app/frontend/   React 19 + Vite + TypeScript + Tailwind + React Flow
app/backend/    Go API (Gin) · PostgreSQL · Redis · Docker SDK · Better Auth sidecar
infra/          Self-hosted compose: Traefik + Cloudflare Tunnel
docs/           Guides, OpenAPI spec, design documents

All configuration is via environment variables — see .env.example. Never commit .env or .env.prod; if a secret was ever committed, rotate it.
