Setup/Installation Requirements

Clone repo to your local system:

1. Make a directory on your disk where you would like to clone the repo.

2. Copy the repo link: https://github.com/Reed-Carter/Climate-Comparison-data (available if you click the green "Code" dropdown button on this page).

3. Open your terminal and change into the directory you made (cd /path/to/new/directory).

4. Type git clone and paste the URL.

Install required packages:

These installation instructions assume you have pip, virtualenv, and Docker Desktop installed.

# Create and activate virtual environment
virtualenv -p python3.7 venv 
source venv/bin/activate

# Install packages from requirements.txt
pip install -r requirements.txt

# Install Airflow 
AIRFLOW_VERSION=2.3.2 
PYTHON_VERSION=3.7 
CONSTRAINT_URL="https://raw.githubusercontent.com/apache/airflow/constraints-${AIRFLOW_VERSION}/constraints-${PYTHON_VERSION}.txt"
pip install "apache-airflow[async,postgres,google]==${AIRFLOW_VERSION}" --constraint "${CONSTRAINT_URL}"

You can create your own airflow directory in the root of this repository and copy any of our DAGs into it if you are interested in running them for yourself.

# Make and change to airflow subdirectory
mkdir airflow && cd "_$"
mkdir ./dags ./plugins ./logs # create subdirectories 

# Download docker-compose.yaml and set the .env  
curl -LfO 'https://airflow.apache.org/docs/apache-airflow/stable/docker-compose.yaml'
echo -e "AIRFLOW_UID=$(id -u)\nAIRFLOW_GID=0" > .env

Prior to initializing Airflow in Docker, you will need to create a project and an associated service account in BigQuery. After downloading the account's credential file, you can configure your docker-compose.yaml to connect to BigQuery:

  GOOGLE_APPLICATION_CREDENTIALS: /google_creds/<name-of-your-creds-file>.json
volumes:
  - ${AIRFLOW_PROJ_DIR:-.}/dags:/opt/airflow/dags
  - ${AIRFLOW_PROJ_DIR:-.}/logs:/opt/airflow/logs
  - ${AIRFLOW_PROJ_DIR:-.}/plugins:/opt/airflow/plugins
  - ${AIRFLOW_PROJ_DIR:-.}/data:/opt/airflow/data
  - </path/to/your/creds/directory>:/google_creds

After opening Docker Desktop (or starting docker via CLI):

# Create and start Docker container from airflow-init image
docker compose up airflow-init
docker compose up
