Automated Management of DigitalOcean Droplet Snapshots
This workflow implements automated management of snapshots for DigitalOcean cloud servers. It regularly checks the number of snapshots for all Droplets, automatically deletes the oldest snapshots that exceed a set threshold, and creates new snapshots, ensuring that backups are always up to date and preventing waste of storage resources. This process not only saves operational time but also reduces the risk of errors associated with manual management, enhancing data security and resource utilization efficiency, making it suitable for cloud operations and DevOps teams.

Automated Management of DigitalOcean Droplet Snapshots
Key Features and Highlights
This workflow automates the management of snapshots for DigitalOcean cloud servers (Droplets). It periodically (by default every 48 hours) checks the number of snapshots for all Droplets, automatically deletes the oldest snapshots exceeding a set threshold (default is 4), and creates new snapshots. This ensures backups are always up-to-date without consuming excessive storage resources.
Core Problems Addressed
If cloud server snapshots are not cleaned up in time, a large amount of historical data accumulates, leading to storage waste and management complexity. Manual snapshot management is time-consuming and prone to errors. This workflow solves the problem of excessive snapshots and ineffective management through automation, ensuring data security while reducing costs.
Use Cases
- Cloud operations teams aiming to automatically maintain backup snapshots of DigitalOcean Droplets.
- DevOps personnel who need to regularly create snapshot backups and clean up old snapshots to ensure a secure and reliable environment.
- Enterprise IT departments looking to reduce operational workload and achieve efficient cloud resource management.
Main Workflow Steps
- Scheduled Trigger (every 48 hours): The workflow is periodically initiated via a cron node.
- Retrieve All Droplets: Calls the DigitalOcean API to get a list of all Droplets in the account.
- Fetch Snapshots for Each Droplet: Queries all snapshots associated with each Droplet.
- Snapshot Count Filtering: Checks if the total number of snapshots meets or exceeds 4.
- Delete Oldest Snapshots: Automatically deletes the oldest snapshots if the count exceeds the threshold.
- Create New Snapshot: After cleanup, creates a new snapshot for the Droplet to maintain backup continuity.
Systems and Services Involved
- DigitalOcean API: Used to retrieve Droplet information, list snapshots, and perform snapshot deletion and creation operations.
- n8n Automation Platform: Serves as the workflow engine to schedule and execute tasks and HTTP requests across nodes.
Target Users and Value
- Cloud Operations Engineers: Simplify snapshot management processes and save maintenance time.
- DevOps Teams: Ensure timely backup updates and efficient storage utilization.
- SME IT Administrators: Reduce manual intervention, minimize error risks, and improve operational efficiency.
With this workflow, you can effortlessly automate the periodic management of DigitalOcean Droplet snapshots, ensuring data security and resource optimization, thereby advancing intelligent cloud environment operations.
Send the Astronomy Picture of the Day Daily to a Telegram Channel
This workflow automatically retrieves NASA's daily astronomical images and sends the images along with their titles to a designated Telegram channel at a fixed time each day. Through automation, users do not need to manually search for and share content, ensuring continuous updates and reducing operational burdens. It is particularly suitable for astronomy enthusiasts and science popularization channel administrators, enhancing operational efficiency and the interest of channel content.
MCP Server for Managing and Executing n8n Workflows
This workflow establishes an intelligent MCP server to centrally manage and invoke automated workflows, enhancing the management efficiency and flexibility of workflows. It can filter available workflows based on tags, supports dynamic addition, removal, and search, and utilizes memory caching and natural language processing technology, allowing intelligent agents to automatically identify and execute the required workflows for efficient automation of complex tasks. This system is particularly suitable for internal enterprise automation and AI assistant applications, improving the intelligence level of digital transformation.
puq-docker-immich-deploy
This workflow is designed to automate the deployment and management of Docker-based Immich service instances, supporting operations such as starting, stopping, mounting, setting permissions, and retrieving logs for containers. Through API interfaces and SSH remote execution, users can flexibly manage the container lifecycle and achieve one-stop status monitoring and user management. Additionally, the built-in nginx proxy configuration feature ensures stable operation of the service in a reverse proxy environment, making it suitable for cloud service providers, system operations personnel, and enterprise IT teams, thereby enhancing operational efficiency and service delivery quality.
Syncro Status Update Clockify
This workflow automatically receives status update requests via Webhook, intelligently synchronizing the archiving status of Clockify projects. Depending on whether the task is resolved, it automatically toggles the Clockify project between "archived" and "active," effectively addressing the cumbersome and error-prone nature of manual operations. It is suitable for teams that need to maintain consistency between task status and time tracking tools, significantly enhancing the efficiency and accuracy of project management, and ensuring that the project status is always in sync with the actual tasks.
Error Monitoring Notification Workflow
This workflow enables real-time monitoring of error events in the automated system. Once an error occurs, a detailed notification is immediately sent via Mattermost, and Twilio SMS alerts are utilized to ensure that relevant personnel are quickly informed of the anomaly. This multi-channel notification mechanism effectively prevents business interruptions or data loss due to undetected issues, enhancing operational efficiency and response speed. It is suitable for teams and enterprises that require real-time monitoring of business processes.
JIRA Issue Intelligent Auto-Assignment Workflow
This workflow intelligently and automatically assigns unassigned tasks that have been pending for more than 5 days by integrating JIRA, OpenAI, and the Supabase vector database. It utilizes AI technology to retrieve similar resolved issues, identify the best team members, and take into account the current task load, ensuring that tasks are assigned efficiently and accurately, while avoiding omissions and resource waste. It is suitable for agile development and project management, significantly reducing the manual allocation workload and enhancing team collaboration and management efficiency.
Receive Messages from an ActiveMQ Queue via AMQP Trigger
This workflow uses the AMQP Trigger node to listen for and receive messages from the ActiveMQ message queue in real-time, ensuring immediate capture and processing of messages. It effectively addresses the efficiency issue of retrieving messages from the ActiveMQ queue, avoiding manual polling or delayed responses, making it suitable for scenarios that require real-time message processing, such as order notifications and system event triggers. This workflow provides developers and operations personnel with tools to enhance message processing efficiency and supports the construction of automated processes.
n8n Update
This workflow implements automatic version detection and updates for running Docker containers. It regularly checks the differences between the current version and the latest released version on GitHub, automatically notifying users if updates are available. Upon user confirmation, it pulls the latest image and restarts the container. Notifications and interactions are conducted via Telegram, allowing users to conveniently manage updates remotely, ensuring that the platform always runs on the latest stable version, thereby enhancing system security and functional integrity.
