How ThinkNCollab Works Like Docker Internally

We didn't just build a lightweight wrapper. ThinkNCollab Shell embeds a 6-layer native runtime that speaks OCI, executes OCI images, and responds to Docker commands without any background VM.

Native OCI Distribution Engine

Implements the OCI Distribution Spec v1.1 and Docker Registry API v2 directly in Node.js. thinknsh pull pulls from Docker Hub, GHCR, AWS ECR, or GCP GCR, unpacks tar layer blobs directly to rootfs, and verifies sha256 checksums without Docker Daemon.

Kernel-Level Sandbox & MicroVM Isolation

Instead of spinning up a heavyweight 4GB Linux VM, we enforce real kernel isolation primitives per operating system: macOS uses Apple Virtualization (tnc-vz MicroVM + crun) with sub-second boot, 60MB idle RAM & VirtioFS; Linux uses Native Kernel Namespaces (unshare / crun - PID, mount, net) + cgroups v2; Windows uses direct WSL2 process execution.

Sub-Second CoW Volume Snapshots

Traditional Docker volumes require exporting multi-gigabyte tar files. ThinkNCollab leverages filesystem Copy-on-Write (APFS cp -cR on macOS and Btrfs/XFS --reflink on Linux) to create zero-cost, instant volume clones in under 15ms.

Drop-in Docker CLI Shim

Keep your muscle memory and existing CI scripts intact. Running thinknsh docker install places a transparent shim at /usr/local/bin/docker that translates commands like docker run, docker ps, and docker compose directly to thinknsh.

Docker REST API Socket Daemon

Need to use VS Code Dev Containers or Testcontainers in unit tests? thinknsh docker socket start exposes an on-demand UNIX socket at ~/.tnc/docker.sock providing the Docker Engine REST API (v1.41) backed 100% by ThinkNCollab's native engine!

Multi-Service Compose & Internal DNS

Run complete microservice stacks defined in docker-compose.yml or thinkncollab.yml. Features port publishing, bridge networking, internal service DNS resolution, and dependency ordering with zero Docker daemon.

Every Command in ThinkNCollab Shell V2

Your exhaustive guide to every native command, alias, and capability available in thinknsh.

thinknsh pull <image>

Pulls OCI image from Docker Hub, GHCR, or ECR without Docker installed. Extracts layers to local rootfs.

bash

            thinknsh pull postgres:16

thinknsh run [options] <image>

Runs an OCI container or blueprint script inside an isolated process sandbox with port bindings and env vars.

bash

            thinknsh run -p 6379:6379 redis:alpine

thinknsh compose <up|down|ps|logs>

Docker Compose equivalent. Orchestrates multi-container stacks with bridge networking and internal DNS.

bash

            thinknsh compose up -d

thinknsh docker install

Installs /usr/local/bin/docker shim so standard docker <cmd> calls automatically run via thinknsh.

bash

            thinknsh docker install

thinknsh docker socket start

Spawns Docker Engine REST API socket daemon at ~/.tnc/docker.sock for VS Code Dev Containers and Testcontainers.

bash

            thinknsh docker socket start

thinknsh snapshot create <name>

Sub-second Copy-on-Write volume snapshot using APFS (macOS) or Btrfs/XFS (Linux) with 0 extra disk penalty.

bash

            thinknsh snapshot create pre-migration

thinknsh push <target>

Pushes local container capsules to AWS ECR, GCP GCR, Docker Hub or exports OCI tarball for Kubernetes/kubectl.

bash

            thinknsh push --export myapp:v1

thinknsh dev [options]

Spawns workspace dev server inside an OS-native sandbox with automatic port forwarding and memory caps.
