Run the ingestion from GitHub Actions
{% note %}
You can find a fully working demo of this setup here.
{% /note %}
The process to run the ingestion from GitHub Actions is the same as running it from anywhere else.
- Get the YAML configuration,
- Prepare the Python Script
- Schedule the Ingestion
1. YAML Configuration
For any connector and workflow, you can pick it up from its doc page.
2. Prepare the Python Script
In the GitHub Action we will just be triggering a custom Python script. This script will:
-
Load the secrets from environment variables (we don't want any security risks!),
-
Prepare the Workflow class from the Ingestion Framework that contains all the logic on how to run the metadata ingestion,
-
Execute the workflow and log the results.
-
A simplified version of such script looks like follows:
import os
import yaml
from metadata.workflow.metadata import MetadataWorkflow
CONFIG = f"""
source:
type: snowflake
serviceName: snowflake_from_github_actions
serviceConnection:
config:
type: Snowflake
username: {os.getenv('SNOWFLAKE_USERNAME')}
...
"""
def run():
workflow_config = yaml.safe_load(CONFIG)
workflow = MetadataWorkflow.create(workflow_config)
workflow.execute()
workflow.raise_from_status()
workflow.print_status()
workflow.stop()
if __name__ == "__main__":
run()
Note how we are securing the credentials using environment variables. You will need to create these env vars in your GitHub repository. Follow the GitHub docs for more information on how to create and use Secrets.
In the end, we'll map these secrets to environment variables in the process, that we can pick up with os.getenv
.
3. Schedule the Ingestion
Now that we have all the ingredients, we just need to build a simple GitHub Actions with the following steps:
-
Install Python
-
Prepare virtual environment with the openmetadata-ingestion package
-
Run the script!
-
It is as simple as this. Internally the function run we created will be sending the results to the OpenMetadata server, so there's nothing else we need to do here.
A first version of the action could be:
name: ingest-snowflake
on:
# Any expression you'd like here
schedule:
- cron: '0 */2 * * *'
# If you also want to execute it manually
workflow_dispatch:
permissions:
id-token: write
contents: read
jobs:
ingest:
runs-on: ubuntu-latest
steps:
# Pick up the repository code, where the script lives
- name: Checkout
uses: actions/checkout@v3
# Prepare Python in the GitHub Agent
- name: Set up Python 3.9
uses: actions/setup-python@v4
with:
python-version: 3.9
# Install the dependencies. Make sure that the client version matches the server!
- name: Install Deps
run: |
python -m venv env
source env/bin/activate
pip install "openmetadata-ingestion[snowflake]==1.0.2.0"
- name: Run Ingestion
run: |
source env/bin/activate
python ingestion-github-actions/snowflake_ingestion.py
# Add the env vars we need to load the snowflake credentials
env:
SNOWFLAKE_USERNAME: ${{ secrets.SNOWFLAKE_USERNAME }}
SNOWFLAKE_PASSWORD: ${{ secrets.SNOWFLAKE_PASSWORD }}
SNOWFLAKE_WAREHOUSE: ${{ secrets.SNOWFLAKE_WAREHOUSE }}
SNOWFLAKE_ACCOUNT: ${{ secrets.SNOWFLAKE_ACCOUNT }}
SBX_JWT: ${{ secrets.SBX_JWT }}
[Optional] - Getting Alerts in Slack
A very interesting option that GitHub Actions provide is the ability to get alerts in Slack after our action fails.
This can become specially useful if we want to be notified when our metadata ingestion is not working as expected. We can use the same setup as above with a couple of slight changes:
- name: Run Ingestion
id: ingestion
continue-on-error: true
run: |
source env/bin/activate
python ingestion-github-actions/snowflake_ingestion.py
# Add the env vars we need to load the snowflake credentials
env:
SNOWFLAKE_USERNAME: ${{ secrets.SNOWFLAKE_USERNAME }}
SNOWFLAKE_PASSWORD: ${{ secrets.SNOWFLAKE_PASSWORD }}
SNOWFLAKE_WAREHOUSE: ${{ secrets.SNOWFLAKE_WAREHOUSE }}
SNOWFLAKE_ACCOUNT: ${{ secrets.SNOWFLAKE_ACCOUNT }}
SBX_JWT: ${{ secrets.SBX_JWT }}
- name: Slack on Failure
if: steps.ingestion.outcome != 'success'
uses: slackapi/slack-github-action@v1.23.0
with:
payload: |
{
"text": "🔥 Metadata ingestion failed! 🔥"
}
env:
SLACK_WEBHOOK_URL: ${{ secrets.SLACK_WEBHOOK }}
SLACK_WEBHOOK_TYPE: INCOMING_WEBHOOK
- name: Force failure
if: steps.ingestion.outcome != 'success'
run: |
exit 1
We have:
- Marked the
Run Ingestion
step with a specificid
and withcontinue-on-error: true
. If anything happens, we don't want the action to stop. - We added a step with
slackapi/slack-github-action@v1.23.0
. By passing a Slack Webhook link via a secret, we can send any payload to a - specific Slack channel. You can find more info on how to set up a Slack Webhook here.
- If our
ingestion
step fails, we still want to mark the action as failed, so we are forcing the failure we skipped before.
