vpc_name: We need an isolated VPC to launch your resources in, so we create one for you. Stick with plural for most cases. This is a cluster-level setting that we only ask for once. Once you have set this up, you won't need to do it again.
wal_bucket: Plural uses Postgres as the backing database for cluster information. We need to store the WAL logs somewhere to backup and restore from. This is a cluster-level setting that we only ask for once. Once you've set this up, you won't need to do it again unless you destroy all existing applications.
airflowBucket: We want to store your Airflow logs in a S3-like bucket for easy access. Use the default by pressing [Enter] unless it's been used before. This configuration step is not idempotent, if you have to redo configuration for any reason, you'll need to create a new bucket. Alternatively you can directly edit the context.yaml file to use the existing bucket that you create in this step.
hostname: This will be where your Airflow instance is hosted. Generally, use airflow.$YOUR_ORG_NAME.onplural.sh.
dagRepo: We'll need a preexisting GitHub repository to store the DAGs that you create and use in Airflow. Either create one now or use an existing DAG repository. Then grab the SSH URL from the Code tab on the repo to use here.
branchName: If you have an existing DAG repository, you may want to sync your existing dags into and from a specific branch. This will be the branch that Plural stays up to date with, so use main unless you want to prevent direct changes to the repository.
adminUsername: Use your naming preference for admin accounts. No need to reinvent the wheel, admin is fine too.
adminFirst: Use your relevant operator's first name or just use admin.
adminLast: Use your relevant operator's last name or just use admin.
adminEmail: Use your relevant admin operator's email address. This will the email used to manage the Airflow instance.
private_key: This makes sure that your admin account has Read/Write access to the DAG repo. We recommend you stick with the default, unless you have compliance reasons for this file not existing here.
public_key: Similar to private_key, this makes sure that your admin account has Read/Write access to the DAG repo. We recommend you stick with the default, unless you have compliance reasons for this file not existing here.
Enable plural OIDC: Enabling Plural OIDC means that you won't need to worry about authenticating into this app if you're logged into Plural. We highly recommend this as long as you don't have any specific security requirements.
