Backend: - tolerate concurrent project-network creation (re-resolve on conflict) - always publish an ephemeral host port when a port is configured, even with a domain set — Traefik routes on top when the edge network exists - public_url now prefers the configured domain, falls back to the first published port - service logs resolve replicas by containr.service label and merge all replica streams — previously queried a nonexistent containr-<id> name Canvas/detail: - degraded status renders amber end-to-end (node card, detail badge, status dot) instead of falling through to "Stopped" - edges pick handle sides by relative node position — no more backward loops when the source sits right of the target - context menu gains Start for stopped services, Visit uses the published URL when no domain is set, menu clamps to canvas bounds - node cards show the image tag instead of a redundant hint - scaling tab falls back to live runtime replica counts when no autoscaler state exists; manual scale no longer requires it Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>
Containr
Self-hosted platform for deploying and managing containerized services. Railway-style project canvases on your own hardware.
Quick Start • Screenshots • Features • Guides • Contributing
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, right-click lifecycle actions
- Private networking — every project gets an isolated Docker network; services reach each other by name (
web:3000) and share variables via${{service.KEY}}references - Deployments & builds — Docker deploys with history, logs, image rollback, live build status
- Runtime — replicas, published ports, domains, health checks, restart policies; start/stop/restart/redeploy from canvas or service page
- 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/password self-hosted), 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.
On first visit you create the owner account (email/password); registration
then closes automatically. The owner can reopen it and configure a Cloudflare
Tunnel token under Settings → Platform — in-app values override env vars.
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):

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