Script for checking and starting Docker containers.

 

Step 1: Install the User Scripts Plugin

1. Open Unraid Web UI: Go to your Unraid server's web interface.

2. Go to Plugins: Navigate to the "Plugins" tab.

3. Install User Scripts: If you don't have it installed, find and install the User Scripts plugin from the Community Applications.

 

Step 2: Create Your Script

1. Open User Scripts: After installation, go to the "User Scripts" tab.

2. Add a New Script: Click on "Add Script".

3. Name Your Script: Give it a descriptive name, e.g., Check Docker Containers.

4. Edit the Script: Click on the script name to edit it, and paste your modified script into the editor:

 

#!/bin/bash

# List of Docker container names or IDs to check
containers=("container1" "container2" "container3")

# Check if Docker is running
if ! systemctl is-active --quiet docker; then
    echo "Docker is not running. Please start Docker and try again."
    exit 1
fi

# Loop through each specified container and check its status
for container in "${containers[@]}"; do
    if ! docker ps -a --format '{{.Names}}' | grep -q "^$container$"; then
        echo "Container $container does not exist."
        continue
    fi

    status=$(docker inspect --format='{{.State.Status}}' "$container" 2>/dev/null)
    if [ $? -ne 0 ]; then
        echo "Failed to inspect container $container. It may not exist."
        continue
    fi

    if [ "$status" != "running" ]; then
        echo "Container $container is not running. Attempting to start it."
        if docker start "$container"; then
            echo "Container $container started successfully."
        else
            echo "Failed to start container $container."
        fi
    else
        echo "Container $container is running."
    fi
done

 

Step 3: Schedule the Script

1. Set Schedule: In the User Scripts page, set the frequency to "Every 15 minutes".

2. Save the Script: Click "Save Changes" to save the script.

 

Additional Tips

1. Customize Container Names: Replace container1, container2, and container3 in the script with the actual names or IDs of your Docker containers.

2. Access Logs: You can view logs from the script runs directly in the User Scripts interface.

Hopefully you meant dockers and not Doctors. 😁

Thanks for the script.
