1.1.2. Get the source code

git clone https://github.com/mesmacosta/datacatalog-tag-template-processor
cd ./datacatalog-tag-template-processor

All paths starting with ./ in the next steps are relative to the datacatalog-tag-template-processor folder.

1.1.3. Create and activate an isolated Python environment

pip install --upgrade virtualenv
python3 -m virtualenv --python python3 env
source ./env/bin/activate

1.1.4. Install the package

pip install --upgrade .

1.2. Docker

Docker may be used as an alternative to run the script. In this case, please disregard the Virtualenv setup instructions.

1.3. Auth credentials

1.3.1. Create a service account and grant it below roles

• Data Catalog Admin

1.3.2. Download a JSON key and save it as

This name is just a suggestion, feel free to name it following your naming conventions

• ./credentials/datacatalog-tag-template-processor-sa.json

1.3.3. Set the environment variables

This step may be skipped if you're using Docker.

export GOOGLE_APPLICATION_CREDENTIALS=~/credentials/datacatalog-tag-template-processor-sa.json

2. Load Templates from CSV file
