How to run

sealos run docker.io/labring/sealos-terminal-controller:latest

Configuration

The terminal controller supports the following environment variables:

• RELEASE_NAME: Helm release name (default: terminal)
• RELEASE_NAMESPACE: Deployment namespace (default: terminal-system)
• CHART_PATH: Path to helm chart (default: ./charts/terminal-controller)
• HELM_OPTS: Additional helm options
• SEALOS_CLOUD_DOMAIN: Cloud domain (auto-detected from sealos-config)
• SEALOS_CLOUD_PORT: Cloud port (auto-detected from sealos-config)
• TERMINAL_BACKUP_ENABLED: Enable resource backup (default: true)
• TERMINAL_BACKUP_DIR: Backup directory (default: /tmp/sealos-backup/terminal-controller)

Deployment Structure

This deployment uses Helm charts for better manageability:

• Chart: charts/terminal-controller/
• Entrypoint: terminal-controller-entrypoint.sh
• CRD: Terminals.terminal.sealos.io

The controller will automatically:

• Create namespace if it doesn't exist (via --create-namespace)
• Adopt existing resources for smooth migration
• Backup resources before upgrades
• Configure from sealos-system configmap
