Mount Docker Data Directory

### **1. Stop Docker**
Since `/var/lib/docker` contains all Docker data, stopping Docker is necessary before making any changes:

sudo systemctl stop docker

### **2. Move Existing Docker Data**
Move the existing Docker data to the new location:

sudo mv /var/lib/docker /home1/docker

### **3. Create a Symlink (Optional)**
If you want Docker to still refer to `/var/lib/docker`, create a symbolic link:

sudo ln -s /home1/docker /var/lib/docker

### **4. Update Docker Daemon Configuration**
Instead of using a symlink, you can also configure Docker to use `/home1/docker` directly. Create or modify `/etc/docker/daemon.json`:

sudo nano /etc/docker/daemon.json

Add the following content:

{
  "data-root": "/home1/docker"
}

Save and exit.

### **5. Restart Docker**

sudo systemctl daemon-reload
sudo systemctl start docker

### **6. Verify the New Location**
Check if Docker is using the new location:

docker info | grep "Docker Root Dir"

If successful, it should show `/home1/docker`.

Let me know if you face any issues!
