usage_description = "
Opens a Cloud SQL Proxy for all instances in given GCP Project( s) or all GCP Projects
Populates \$ HOME/cloud_sql.socks/ directory with all your Cloud SQL instances sockets
Makes it quicker and easier to connect than slow 'gcloud sql connect' commands ( which also requires a public IP address attached to your SQL instance)
Usage:
${ 0 ##*/ }
psql -h ~/cloud_sql.socks/<instance> ...
mysql -S ~/cloud_sql.socks/<instance> ...
Auto-installs Google Cloud SQL Proxy if not found in \$ PATH
Restart to pick up any new Cloud SQL instances
Useful to quick interactive DBA work
For production long-lived proxying, use dedicated Cloud SQL Proxy instances with service account credentials ( avoid application default login expiry or restarts for picking up new instances)
