Files

File	Description
`Dockerfile`	Container image definition
`docker-compose.yml`	Service orchestration with Ofelia labels
`entrypoint.sh`	Parses ../env and exports variables
`run-subscription.sh`	Master orchestration script
`start-automation.sh`	Quick-start helper script
`README.md`	This file

Environmental Variables

Single Source of Truth: `../env`

All configuration is stored in one file: ../env (in the parent directory)

This file uses Perl-style syntax (which existing scripts expect):

$VARIABLE_NAME = "value";

How It Works

../env is the single source of truth for all configuration
The entrypoint.sh script parses ../env and exports variables as environment variables
All scripts can then access them via standard environment variable syntax ($VARIABLE_NAME)

Configuration Variables

Required for Subscription

Variable	Description	Example
`$CONNECTOR_URL`	URL of mailman-connector	`https://mailman-connector.example.org`
`$CONNECTOR_PASSWORD`	Secret password for connector API	`your_secret_password`
`$MAILMAN_LIST_ID`	Target mailing list ID	`members.lists.example.org`

Required for Portal Download

Variable	Description	Example
`$PORTAL_URL`	LWVWV portal URL	`https://portal.lwv.org`
`$MEMBERSHIP_URL`	Membership page URL	`https://portal.lwv.org/groups/...`

Email Notifications (Optional)

Variable	Description	Example
`$SMTP_HOST`	SMTP server	`mail.example.org`
`$SMTP_PORT`	SMTP port	`587`
`$SMTP_USER`	SMTP username	`example@example.org`
`$SMTP_PASSWORD`	SMTP password	`your_smtp_password`
`$EMAIL_FROM`	Sender address	`example@example.org`
`$EMAIL_TO`	Recipient for alerts	`hello@example.org`

Google API (for district lookup)

Variable	Description	Example
`$key`	Google Civic API key	`AIzaSy...`
`$STATE`	State code	`WV`
`$stateLeagueID`	State league ID	`WV000`
`$localLeagueIDs`	Local league IDs	`WV102

Example `../env` File

# Portal Configuration
$PORTAL_URL = "https://portal.lwv.org";
$MEMBERSHIP_URL = "https://portal.lwv.org/groups/53a93df1/league_membership_state_view";

# Connector Settings
$CONNECTOR_URL = "https://mailman-connector.example.org";
$CONNECTOR_PASSWORD = "your_secret_password";
$MAILMAN_LIST_ID = "members.lists.example.org";

# Email Notification Settings
$SMTP_HOST = "mail.example.org";
$SMTP_PORT = "587";
$SMTP_USER = "example@example.org";
$SMTP_PASSWORD = "your_smtp_password";
$EMAIL_FROM = "example@example.org";
$EMAIL_TO = "hello@example.org";

# Google API Configuration
$key = "LALKDdkdk_12LSL_RKFDL";
$STATE = "WV";
$stateLeagueID = "WV000";
$localLeagueIDs = "WV102|WV103|WV112";

Quick Start

1. Configure Environment

Ensure ../env exists with your settings:

cd automation
# The env file should already exist in the parent directory
ls ../env

2. Build and Start

docker-compose up -d

3. Verify Container is Running

docker ps | grep lwvwv-subscriber

Usage

Manual Trigger (for testing)

# Run the full workflow (downloads roster, converts, subscribes)
docker exec lwvwv-subscriber /app/run-subscription.sh

# With a specific CSV file (skips download)
docker exec lwvwv-subscriber /app/run-subscription.sh /path/to/members.csv

# Run subscribe-members.sh directly with env vars
docker exec lwvwv-subscriber /app/subscribe-members.sh /tmp/rosters/members.csv

Scheduled Execution (via Ofelia)

The container includes Ofelia labels for automatic scheduling:

Default: 4x daily at 00:00, 06:00, 12:00, 18:00
Format: Cron expression 0 0,6,12,18 * * *

To change schedule, edit docker-compose.yml:

labels:
  ofelia.enabled: "true"
  ofelia.job-exec.lwvwv-subscribe.schedule: "0 0,6,12,18 * * *"

Standalone Usage (without Docker)

The scripts also work outside Docker using positional arguments:

# subscribe-members.sh with all positional args
./subscribe-members.sh members.csv mypassword members.lists.example.org https://connector.example.com

# With some env vars, some positional
CONNECTOR_PASSWORD=mypassword ./subscribe-members.sh members.csv

Logs

# View container logs
docker logs lwvwv-subscriber

# Follow logs in real-time
docker logs -f lwvwv-subscriber

# View Ofelia scheduler logs
docker logs ofelia

Troubleshooting

Session Expired

If portal download fails with "Session expired":

# Run save-session.js on host to refresh session
cd ..
node save-session.js
# Then restart container
docker-compose restart

Missing Environment Variables

If you see errors like CONNECTOR_URL not set:

Check that ../env exists and contains the variable

Verify the entrypoint is parsing it correctly:

docker exec lwvwv-subscriber env | grep CONNECTOR

Manual CSV Subscription

To subscribe members without downloading:

# Place CSV file in shared volume
cp members.csv automation/rosters/

# Run with specific file
docker exec lwvwv-subscriber /app/run-subscription.sh /tmp/rosters/members.csv

Network Requirements

The container needs access to:

LWV Portal (https://portal.lwv.org)
SMTP server (if using email alerts)

Security Notes

../env is mounted read-only (:ro) in the container
Sensitive data is never committed to git
Session file (.session.json) is also mounted read-only
All scripts use the single ../env file - no duplicated configuration
