Service Onboarding using Scripts on Catalog

Scripts to create new services, register new services​

  • The GitHub Catalog Discovery plugin registers one location per repository. This might not be a good idea when there are many (3000+ in this case) as any error in fetching one catalog-yaml would mark the whole location as failed and create trouble with the entity sync.

  • To solve this we would recommend you to use the following scripts which would register separate locations for all the matching catalog-info.yaml files and hence would be synchronised separately.

Download the Script​

  • A pregenerated/created repo (let's call it chosen_repo) is to be cloned. After opening it on your code editor and from chosen_repo, below commands can be run to first download and then generate and register catalog-info.yaml files of all the repos in your org. The catalog-info.yaml files will be in - chosen_repo/services/{repos}/catalog-info.yaml where repos will be all the repo in your org.

  • Command to Download the Script

curl -o idp-catalog-wizard-github.py https://raw.githubusercontent.com/harness-community/idp-samples/main/catalog-scripts/idp-catalog-wizard-github.py
python3 idp-catalog-wizard-github.py [OPTIONS]

  • Case 1: Run command using --create-yamls args, then you'll have to manually push the files - "services/" ..... after which you can run command using --register-yamls args to register all the yamls.

  • Case 2: Run command using --run-all args, all actions will be performed - create, push and register in one go.

Registered Locations​

Register YAML files using X-API-Key and account name (all given args in command below are required)​

python3 idp-catalog-wizard-github.py --register-yamls --org org_name --x_api_key your_x_api_key --account your_account

--org ORG_NAME: Github Org name
--x_api_key X_API_KEY: Refer https://developer.harness.io/docs/platform/automation/api/api-quickstart/#create-a-harness-api-key-and-token to generate one
--account ACCOUNT_NAME: This is your harrness-account id. Ex - https://app.harness.io/ng/account/{Your account}/module/idp/overview

Perform all actions: create YAML files, push changes, and register YAML files (all given args in command below are required)​

python3 idp-catalog-wizard-github.py --run-all --org example-org --token your_token --x_api_key your_x_api_key --account your_account

Registered Locations - For Monorepos​

  • Discover catalog-info.yaml matching the regex filter and register under the catalog provided in apiurl. This would separate locations for all the matching catalog-info.yaml files and hence would be synchronized separately.

  • To use the script you need to add the appropriate flags and run it.

Create Services​

  • Generates a monorepo with the following file structure, assigning random english names.
repo
   - antronasal-service
      - catalog-info.yaml
   - cespititous-service
      - catalog-info.yaml
   - ....
   - geomaly-service
        - catalog-info.yaml

Delete Services​

  • Will clean up the services already created.
