Secure Connector Container

  • Last updated on

The Secure Connector running firmware 1.1.0 or higher can now run a single LXC container. Linux containers must be enabled in the Secure Connector configuration. The container is assigned an IP address from the data network defined on the Firewall Control Center.

The container is distributed and installed via the firmware update page on the Control Center. The container is transferred and then unpacked on the Secure Connector. All deb packages are installed, and the doit script is executed during deployment. The /root/start.sh script is executed every time the Secure Connector is started. To allow SSH access, a Secure Connector firewall management rule must be added to allow traffic into the container zone.

The new enhanced container feature for LXC, Docker, and IoT Edge is currently in EA and thus free of charge until at least December 2020. Starting January 2021, this new functionality will be available for purchase and all existing deployments will need to be licensed.

Resource Limits for Containers

  • 1 CPU core
  • 512 MB RAM
  • 2 GB Storage 

Container Requirements

Each container must be in a .tgz archive. The file name must include the string container. E.g, my_container.tgz or my_container_v01.tgz

  • deb packages – The deb packages must be compiled for ARM-HF.
  • doit – This script is executed during the installation.
  • /root/start.sh – This script is executed every time the Secure Connector boots and after the installation of the container.

  1. Go to your cluster > Cluster Settings > Secure Connector Editor.
  2. Click Lock.
  3. Double-click to edit the device or Secure Connector template.

Create a Firewall Rule

  • Allow – Select the check box.
  • Source ZoneSelect CONT. This is the zone associated with the container.
  • Services – Select SSH.

Install a Container via Firmware Update in Barracuda Firewall Admin

Containers are installed just like Secure Connector firmware updates. Copy the container .tgz file to the Control Center and distribute it just like a firmware update. When the archive is on the Secure Connector, the deb packages are installed and the installation scripts executed.

For more information, see Secure Connector Firmware Update.
