🐳 Ditch Docker Desktop: A Clean Lima + Docker Setup on macOS

If you’re developing on macOS and feel like Docker Desktop is eating too much RAM (or just want more control), there’s a better way.

I recently switched to Lima + Docker CLI, and honestly — it’s faster, lighter, and way more flexible.

Here’s a complete guide to get you up and running.

🤔 Why move away from Docker Desktop?

Docker Desktop is convenient, but:

• It’s resource-heavy (often 2–4GB idle)
• It abstracts too much (harder to debug)
• Licensing concerns for some teams

👉 With Lima, you get:

• A lightweight Linux VM
• Full control over Docker setup
• Better performance on Apple Silicon

🧭 What you’ll achieve

By the end, you’ll have:

• Docker CLI running on macOS
• Docker daemon inside Lima VM
• Multi-arch builds (arm64 + amd64)
• Docker Compose working
• No Docker Desktop needed

🚀 Step 1: Install prerequisites

brew install lima docker docker-buildx docker-compose docker-compose-switch

⚙️ Step 2: Start Lima Docker VM

limactl start template://docker (or docker-rootful)

This template does a lot for you:

• Creates the VM
• Installs Docker
• Configures networking

🔍 Step 3: Verify Lima

limactl list

You should see your VM running.

🔌 Step 4: Connect Docker CLI → Lima

docker context create lima-docker \
  --docker "host=unix:///Users/$USER/.lima/docker/sock/docker.sock"

docker context use lima-docker

Now your macOS Docker CLI talks to the Lima VM.

🏗️ Step 5: Enable buildx

mkdir -p ~/.docker/cli-plugins

ln -sf $(brew --prefix)/opt/docker-buildx/bin/docker-buildx \
       ~/.docker/cli-plugins/docker-buildx

Verify:

docker buildx version

🔁 Step 6: Create a multi-arch builder

docker buildx create \
  --name multiarch \
  --use \
  --driver docker-container \
  --bootstrap

🌍 Step 7: Enable multi-arch builds (QEMU)

docker run --privileged --rm tonistiigi/binfmt --install all

This allows you to build amd64 images on Apple Silicon.

🧩 Step 8: Enable Docker Compose

mkdir -p ~/.docker/cli-plugins

ln -sf $(brew --prefix)/opt/docker-compose/bin/docker-compose \
       ~/.docker/cli-plugins/docker-compose

Verify:

docker compose version

🧪 Step 9: Test your setup

docker run hello-world
docker ps

If this works — you’re done 🎉

⚠️ Important notes

• Use --load → for local builds (single architecture)
• Use --push → for multi-arch builds
• Avoid --no-cache unless debugging
• BuildKit (buildx) runs in its own container (separate cache)

⚡ Bonus: Dev vs Production builds

Local dev (fast):

docker buildx build --platform linux/arm64 --load .

Production (multi-arch):

docker buildx build --platform linux/arm64,linux/amd64 --push .

🏁 Final thoughts

Switching to Lima gives you:

• 🔥 Better performance
• 🧠 More control
• 💻 Cleaner setup

You essentially get a DIY Docker Desktop — but lighter and faster.

If you’re serious about optimizing your dev environment on macOS, this setup is absolutely worth it.
