# Script to manually trigger GitLab pipeline for WebCMS development deployments
#
# Usage after pushing to GitHub:
# 1. Go to GitLab: https://gitlab.epa.gov/drupalcloud/drupalclouddeployment/-/settings/repository
# 2. Find "Mirroring repositories" section
# 3. Click "Update now" button next to the GitHub mirror
# 4. Run this script: ./trigger-pipeline.sh
#
# One-time Setup:
# 1. Create a Personal Access Token in GitLab:
#    - Go to: https://gitlab.epa.gov/-/user_settings/personal_access_tokens
#    - Token name: "WebCMS Pipeline Trigger"
#    - Scopes: Select "api" (full API access)
#    - Click "Create personal access token"
#    - Copy the token (you won't see it again!)
#
# 2. Set your token as an environment variable (add to ~/.bashrc for persistence):
#    export GITLAB_TOKEN="your-token-here"

# Default to development branch (hardcoded for safety)
BRANCH="${1:-development}"
GITLAB_TOKEN="${2:-$GITLAB_TOKEN}"

# Only allow development branch
