Codecov

In this example you are going to create a webhook integration between Codecov and Port. The integration will facilitate the ingestion of coverage entities into Port.

Port configuration

Create the following blueprint definitions:

Codecov coverage blueprint
{
"identifier": "codecov_coverage",
"title": "Codecov Coverage",
"icon": "Git",
"schema": {
"properties": {
"repository": {
"title": "Repository",
"type": "string",
"format": "url"
},
"coverage": {
"title": "Test Coverage",
"type": "string"
},
"service": {
"title": "Service",
"type": "string"
},
"author": {
"title": "Author",
"type": "string"
},
"createdAt": {
"title": "Created At",
"type": "string",
"format": "date-time"
},
"files": {
"title": "Tracked Files",
"type": "string",
"description": "Number of files tracked"
},
"lines": {
"title": "Tracked Lines",
"description": "Number of lines tracked",
"type": "string"
},
"branch": {
"title": "Branch",
"type": "string"
},
"report": {
"title": "Full Report Data",
"type": "object",
"description": "Detailed information about the codecov report"
}
},
"required": []
},
"mirrorProperties": {},
"calculationProperties": {},
"aggregationProperties": {},
"relations": {}
}

Create the following webhook configuration using Port's UI:

Codecov webhook configuration
  1. Basic details tab - fill the following details:

    1. Title : Codecov Mapper;
    2. Identifier : codecov_mapper;
    3. Description : A webhook configuration to map Codecov coverage to Port;
    4. Icon : Git;
  2. Integration configuration tab - fill the following JQ mapping:

    [
    {
    "blueprint": "codecov_coverage",
    "filter": "true",
    "entity": {
    "identifier": ".body.repo.name | tostring",
    "title": ".body.repo.name | tostring",
    "properties": {
    "repository": ".body.repo.url",
    "coverage": ".body.head.totals.coverage",
    "service": ".body.owner.service",
    "author": ".body.head.author.name",
    "createdAt": ".body.head.timestamp | (strptime(\"%Y-%m-%dT%H:%M:%S\") | strftime(\"%Y-%m-%dT%H:%M:%SZ\"))",
    "files": ".body.head.totals.files",
    "lines": ".body.head.totals.lines",
    "branch": ".body.head.branch",
    "report": ".body.head.totals"
    }
    }
    }
    ]
    Webhook URL

    Take note of, and copy the Webhook URL that is provided in this tab

  3. Click Save at the bottom of the page.

Create a webhook in Codecov

  1. From your Codecov account, open Settings;

  2. Click on the Global YAML tab at the left sidebar menu;

  3. In the YAML editor, add the following Codecov configuration to notify Port anytime an event occurs in your code repositories:

    coverage:
    notify:
    webhook:
    default:
    only_pulls: false
    url: YOUR_PORT_WEBHOOK
    Webhook URL replacement

    Remember to replace YOUR_PORT_WEBOOK with the value of the URL you received after creating the webhook configuration in Port.

    notification service customization

    For more information on customizing the notification service, follow this guide

  4. Click Save changes to save the webhook configuration.

For more information on customizing the notification service, follow this documentation

All set! When any changes occur in your Codecov account, a webhook event will be triggered to the URL provided by Port. Port will then parse the events based on the mapping and subsequently update the catalog entities.

Import historical Codecov coverage

In this example you are going to use the provided Python script to fetch coverage data from Codecov REST API and ingest it to Port.

Prerequisites

This example utilizes the same blueprint and webhook definition from the previous section.

In addition, provide the following environment variables:

  • PORT_CLIENT_ID - Your Port client id
  • PORT_CLIENT_SECRET - Your Port client secret
  • CODECOV_TOKEN - Codecov API access token
  • CODECOV_SERVICE_PROVIDER - Git hosting service provider. Accepts values such as github, github_enterprise, bitbucket, bitbucket_server, gitlab and gitlab_enterprise
  • CODECOV_SERVICE_PROVIDER_ACCOUNT_NAME - Username from the Git service provider
Credentials

Find your Port credentials using this guide

Find your Codecov API token using this guide

Use the following Python script to ingest historical Codecov coverage into port:

Codecov Python script
## Import the needed libraries
import requests
from decouple import config
from loguru import logger
from typing import Any

# Get environment variables using the config object or os.environ["KEY"]
# These are the credentials passed by the variables of your pipeline to your tasks and in to your env

PORT_CLIENT_ID = config("PORT_CLIENT_ID")
PORT_CLIENT_SECRET = config("PORT_CLIENT_SECRET")
CODECOV_TOKEN = config("CODECOV_TOKEN")
CODECOV_SERVICE_PROVIDER = config("CODECOV_SERVICE_PROVIDER")
CODECOV_SERVICE_PROVIDER_ACCOUNT_NAME = config("CODECOV_SERVICE_PROVIDER_ACCOUNT_NAME")
CODECOV_API_URL = "https://api.codecov.io/api/v2"
PORT_API_URL = "https://api.getport.io/v1"

ALLOWED_SERVICE_PROVIDERS = {
"github",
"github_enterprise",
"bitbucket",
"bitbucket_server",
"gitlab",
"gitlab_enterprise",
}

if CODECOV_SERVICE_PROVIDER not in ALLOWED_SERVICE_PROVIDERS:
raise ValueError(
f"Invalid CODECOV_SERVICE_PROVIDER: {CODECOV_SERVICE_PROVIDER}. Allowed values are {', '.join(ALLOWED_SERVICE_PROVIDERS)}"
)

## Get Port Access Token
credentials = {"clientId": PORT_CLIENT_ID, "clientSecret": PORT_CLIENT_SECRET}
token_response = requests.post(f"{PORT_API_URL}/auth/access_token", json=credentials)
access_token = token_response.json()["accessToken"]

# You can now use the value in access_token when making further requests
port_headers = {"Authorization": f"Bearer {access_token}"}


def add_entity_to_port(blueprint_id: str, entity_object: dict[str, Any]):
response = requests.post(
f"{PORT_API_URL}/blueprints/{blueprint_id}/entities?upsert=true&merge=true",
json=entity_object,

)
logger.info(response.json())

while url:
try:
response = requests.get(url=url, params=query_params)
response.raise_for_status()
page_json = response.json()
batch_data = page_json["results"]
yield batch_data

url = page_json.get("next")

except requests.exceptions.HTTPError as e:
logger.error(f"HTTP error with info: {e}")
raise

logger.info(f"Successfully fetched paginated data for {path}")


def process_repository_entities(repository_data: list[dict[str, Any]]):
blueprint_id = "codecov_coverage"
for repo in repository_data:
report: dict[str, Any] = repo.get("totals", {})
entity = {
"identifier": repo["name"],
"title": repo["name"],
"properties": {
"repository": f"https://app.codecov.io/{repo['author']['service']}/{repo['author']['username']}/{repo['name']}",
"coverage": report.get("coverage") if report else None,

"createdAt": repo["updatestamp"],
"files": report.get("files") if report else None,
"lines": report.get("lines") if report else None,

"branch": repo["branch"],
},
"relations": {},
}
add_entity_to_port(blueprint_id=blueprint_id, entity_object=entity)


if __name__ == "__main__":
logger.debug("Starting Codecov app")
repository_path = (
f"{CODECOV_SERVICE_PROVIDER}/{CODECOV_SERVICE_PROVIDER_ACCOUNT_NAME}/repos"
)
for repositories_batch in get_paginated_resource(path=repository_path):
logger.debug(
f"Received Codecov repositories batch with size {len(repositories_batch)}"
)
process_repository_entities(repository_data=repositories_batch)

logger.debug("Finished Codecov app")

Running the python script

To ingest coverage data from your Codecov account to Port, run the following commands:

export PORT_CLIENT_ID=<ENTER CLIENT ID>
export PORT_CLIENT_SECRET=<ENTER CLIENT SECRET>
export CODECOV_TOKEN=<ENTER CODECOV TOKEN>
export CODECOV_SERVICE_PROVIDER=<ENTER CODECOV SERVICE PROVIDER>
export CODECOV_SERVICE_PROVIDER_ACCOUNT_NAME=<ENTER CODECOV SERVICE PROVIDER ACCOUNT NAME>

git clone https://github.com/port-labs/example-codecov-test-coverage.git

cd example-codecov-test-coverage

pip install -r ./requirements.txt

python app.py

Done! you are now able to import historical coverage from Codecov into Port. Port will parse the objects according to the mapping and update the catalog entities accordingly.
