Rancher Python API Docs | dltHub

Build a Rancher-to-database pipeline in Python using dlt with AI Workbench support for Claude Code, Cursor, and Codex.

Last updated:

Rancher API documentation is available at https://ranchermanager.docs.rancher.com/api/api-reference. For Rancher 2.x, refer to the v3 API documentation. Rancher uses Docker Compose terminology for services. The REST API base URL is https://<RANCHER_FQDN>/v3 and All requests require API key credentials sent via HTTP Basic authentication.

dlt is an open-source Python library that handles authentication, pagination, and schema evolution automatically. dlthub provides AI context files that enable code assistants to generate production-ready pipelines. Install with uv pip install "dlt[workspace]" and start loading Rancher data in under 10 minutes.


What data can I load from Rancher?

Here are some of the endpoints you can load from Rancher:

ResourceEndpointMethodData selectorDescription
rancher_api_rootv3GETAPI root; returns schemas and links
clustersv3/clustersGETdataList clusters
projectsv3/projectsGETdataList projects
nodesv3/nodesGETdataList nodes
podsv3/podsGETdataList pods
usersv3/usersGETdataList users
services_v1/v2-beta/projects/{projectId}/servicesGETdataRancher v1.6/v2‑beta service list
secondary_launch_config_v1/v2-beta/secondaryLaunchConfigGETdatav2‑beta secondaryLaunchConfig list

How do I authenticate with the Rancher API?

Create an API key in the Rancher UI and send it as HTTP Basic Authorization (Base64 of "ID:SECRET"). For RK‑API, place the same key string in the kubeconfig token field.

1. Get your credentials

  1. Open the Rancher UI and click your user avatar.
  2. Choose Account & API Keys.
  3. Click Add Key, give it a name, and confirm.
  4. Copy the displayed API Key ID and Secret (shown only once).
  5. Use "ID:SECRET" as the Basic auth credential or as the token in a kubeconfig file.

2. Add them to .dlt/secrets.toml

[sources.rancher_source] api_key = "<API_KEY_ID>:<API_KEY_SECRET>"

dlt reads this automatically at runtime — never hardcode tokens in your pipeline script. For production environments, see setting up credentials with dlt for environment variable and vault-based options.


How do I set up and run the pipeline?

Set up a virtual environment and install dlt:

uv venv && source .venv/bin/activate uv pip install "dlt[workspace]"

1. Install the dlt AI Workbench:

dlt ai init --agent <your-agent> # <agent>: claude | cursor | codex

This installs project rules, a secrets management skill, appropriate ignore files, and configures the dlt MCP server for your agent. Learn more →

2. Install the rest-api-pipeline toolkit:

dlt ai toolkit rest-api-pipeline install

This loads the skills and context about dlt the agent uses to build the pipeline iteratively, efficiently, and safely. The agent uses MCP tools to inspect credentials — it never needs to read your secrets.toml directly. Learn more →

3. Start LLM-assisted coding:

Use /find-source to load data from the Rancher API into DuckDB.

The rest-api-pipeline toolkit takes over from here — it reads relevant API documentation, presents you with options for which endpoints to load, and follows a structured workflow to scaffold, debug, and validate the pipeline step by step.

4. Run the pipeline:

python rancher_pipeline.py

If everything is configured correctly, you'll see output like this:

Pipeline rancher_pipeline load step completed in 0.26 seconds 1 load package(s) were loaded to destination duckdb and into dataset rancher_data The duckdb destination used duckdb:/rancher.duckdb location to store data Load package 1749667187.541553 is LOADED and contains no failed jobs

Inspect your pipeline and data:

dlt pipeline rancher_pipeline show

This opens the Pipeline Dashboard where you can verify pipeline state, load metrics, schema (tables, columns, types), and query the loaded data directly.


Python pipeline example

This example loads clusters and projects from the Rancher API into DuckDB. It mirrors the endpoint and data selector configuration from the table above:

import dlt from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources @dlt.source def rancher_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://<RANCHER_FQDN>/v3", "auth": { "type": "http_basic", "api_key": api_key, }, }, "resources": [ {"name": "clusters", "endpoint": {"path": "v3/clusters", "data_selector": "data"}}, {"name": "projects", "endpoint": {"path": "v3/projects", "data_selector": "data"}} ], } yield from rest_api_resources(config) def get_data() -> None: pipeline = dlt.pipeline( pipeline_name="rancher_pipeline", destination="duckdb", dataset_name="rancher_data", ) load_info = pipeline.run(rancher_source()) print(load_info)

To add more endpoints, append entries from the resource table to the "resources" list using the same name, path, and data_selector pattern.


How do I query the loaded data?

Once the pipeline runs, dlt creates one table per resource. You can query with Python or SQL.

Python (pandas DataFrame):

import dlt data = dlt.pipeline("rancher_pipeline").dataset() sessions_df = data.clusters.df() print(sessions_df.head())

SQL (DuckDB example):

SELECT * FROM rancher_data.clusters LIMIT 10;

In a marimo or Jupyter notebook:

import dlt data = dlt.pipeline("rancher_pipeline").dataset() data.clusters.df().head()

See how to explore your data in marimo Notebooks and how to query your data in Python with dataset.


What destinations can I load Rancher data to?

dlt supports loading into any of these destinations — only the destination parameter changes:

DestinationExample value
DuckDB (local, default)"duckdb"
PostgreSQL"postgres"
BigQuery"bigquery"
Snowflake"snowflake"
Redshift"redshift"
Databricks"databricks"
Filesystem (S3, GCS, Azure)"filesystem"

Change the destination in dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. See the full destinations list.
