Creating a Pipeline Tutorial

This tutorial will guide you through the process of creating an end-to-end pipeline with Octopipe. By the end of this guide, you will have a working pipeline that extracts data from a source, transforms it, and loads it into a destination.

​
Overview

Octopipe’s streamlined CLI and opinionated architecture make it easy to build data pipelines quickly. This tutorial covers:
  • Project initialization
  • Authentication
  • Adding a data source and destination
  • Defining a transformation
  • Creating, starting, and monitoring a pipeline

​
Step 1: Initialize Your Project

Begin by setting up your project directory. This command creates the necessary configuration files and folder structure: 
octopipe init --name my_pipeline --description "ETL pipeline for sales data" --local
The —local flag indicates that you are setting up the project for local development. Step 2: Authenticate Authenticate your CLI session with your API key to access Octopipe features: 
octopipe login --api-key YOUR_API_KEY_HERE
• Note: Make sure your API key is valid. If using username/password, you can provide those credentials instead. Step 3: Add a Data Source Configure a data source from which to extract your data. For example, to add a sales API: 
octopipe source add --name sales_api --type api --option url=https://api.sales.com/data --option token=SALES_TOKEN
• Key Points: • —name assigns a unique identifier. • —type specifies the kind of source. • Additional —option flags supply connection details. Step 4: Add a Data Destination Next, configure where the data will be loaded. In this example, we add a PostgreSQL destination: 
octopipe destination add --name sales_db --type postgres --option host=localhost --option port=5432 --option user=dbuser --option password=secret --option database=sales
• Details: This command sets up the connection parameters for your destination. Step 5: Define a Transformation Create a transformation to map the type safe API schema to your destination schema. Use a schema file to define the mapping: 
octopipe transform add --name sales_transform --source sales_api --destination sales_db --schema-file ./schemas/sales_schema.json
• What Happens: The command generates a transformation layer which you can review and approve before execution. Step 6: Create the Pipeline Once all components are in place, create the pipeline: 
octopipe pipeline create --name daily_sales --source sales_api --destination sales_db --transform sales_transform --schedule "0 0 * * *"
• Schedule Explanation: The cron expression “0 0 * * *” schedules the pipeline to run daily at midnight. Step 7: Start the Pipeline Launch your pipeline to begin processing data: 
octopipe start daily_sales
• Verification: Ensure the pipeline starts correctly by checking for confirmation messages. Step 8: Monitor Pipeline Execution To view real-time logs and monitor the pipeline, run: 
octopipe logs daily_sales --follow
• Tip: Use additional options such as —tail 50 to view the last 50 lines if needed. Conclusion Congratulations! You have successfully created and launched your first Octopipe pipeline.
