Bridge for the Automation Service

You can only run custom actions or integrations outside of the Sumo Logic cloud in an "on-premise" environment. For on-premise environments, you need to install a bridge as described below.


Hardware requirements

  • OS:
    • Ubuntu (18.04/20.04)
    • CentOS 7
    • RedHat 8
  • RAM: 8GB
  • CPU: 4 Core
  • DISK: 160GB
  • Network card: 1

Network requirements

The Bridge has to be able to resolve DNS hostnames and needs to reach the below destinations


* Needed only to connect to docker hub.

Install Docker

  1. Install Docker-CE following the installation instructions in Docker Docs. Install at least version 20.10 (do not use nightly build).
  2. As soon as the docker daemon is installed, start it with:
    systemctl start docker
  3. Enable it on boot:
    systemctl enable docker

Using a proxy

  1. If docker has to use a proxy to pull images, follow the below instructions:
    mkdir -p /etc/systemd/system/docker.service.d
  2. Create a file named /etc/systemd/system/docker.service.d/http-proxy.conf, and add:
  3. Reload the systemd daemon with:
    systemctl daemon-reload
  4. And restart docker service with:
    systemctl restart docker

Get installation token

Login to Sumo Logic and create a new installation token with name prefix csoar-bridge-token.

Automation bridge installation


  1. Access the Automation Service.
  2. Click ? in the upper-right corner of the UI.
  3. In the Automation Bridge Manual box, click UBUNTU.
  4. Click Download to download the automation-bridge-X.X.deb file.
  5. Copy the file to the bridge virtual machine.
  6. To install the package run from ssh:
    sudo dpkg -i automation-bridge-X.X.deb


  1. Access the Automation Service.
  2. Click ? in the upper-right corner of the UI.
  3. In the Automation Bridge Manual box, click CENTOS/REDHAT.
  4. Click Download to download the automation-bridge-X.X.rpm file.
  5. Copy the file to the bridge virtual machine.
  6. To install the package run from ssh:
    sudo yum install automation-bridge-X.X.rpm

Installation configuration

  1. Edit the file /opt/automation-bridge/etc/user-configuration.conf and set the below mandatory parameters:
    • 1SOAR_URL1
    • 1SOAR_TOKEN1
  2. To determine which is the correct SOAR_URL, see Sumo Logic Endpoints by Deployment and Firewall Security and get the URL under the API Endpoint column. For example:

And you can set this optional parameter (do not include spaces and must be less than 20 characters): ALIAS

An example of a configuration file would be:


Bridge ALIAS

With bridge ALIAS, it is possible to distinguish which integration resources will be executed with this automation bridge. When a new integration resource is created or edited it is possible to select the default ALIAS or to create a new one. So every automatic action configured to use this resource will be performed with the Bridge that has the same ALIAS.

Create ALIAS bridgeUse default ALIAS bridge

Automation bridge update

For Ubuntu and CentOS/RedHat, the update process works as the installation process. Follow the same steps described in Automation bridge installation above.


If you are not using the SIEM:

  1. Set SIEM_URL to NONE.
  2. Restart the service with:
    systemctl restart automation-bridge
  3. If you need to allow automation-bridge communication through a proxy, edit the file /etc/opt/automation-bridge/automation-bridge.conf and set the correct value. Below is an example:
  4. Restart the service with:
    systemctl restart automation-bridge

Configuring the automation bridge for high availability

You may elect to deploy and register multiple bridges to your tenant for high availability. To cluster automation bridges together logically within the Automation Service and ensure high availability, you must set the same ALIAS for each bridge within the cluster in each respective user-configuration.conf file upon installation. When multiple bridges are registered with the same ALIAS, they will appear as active. If one or more bridges within the cluster go offline, playbooks will execute via the active nodes utilizing the same ALIAS. So long as there is parity between the nodes and there is at least one active node registered, there will be no disruption in playbook execution. It is important to note that integration actions within the playbook must have the appropriate bridge ALIAS assigned within the resource configuration and that connectivity can be established with the appropriate resources. Advanced playbooks may elect to utilize multiple bridge clusters leveraging multiple aliases.

Post-installation checks

To check if the bridge is running correctly, run the following command:

ps faux |grep automation-bridge

This is an example of running automation-bridge:
Example of running automation-bridge

On the Bridge tab in the Automation Service UI, a list of live bridge agents will be displayed along with their status.

Configuring the automation bridge for CyberArk

If you are using CyberArk, you must add the following certificates provided by CyberArk to the /opt/automation-bridge/ directory:

  • RootCA_new.crt
  • client_new.crt
  • client_new.pem

Configuring automation bridge with Podman

Enable Podman socket

  1. Run the following commands:
    systemctl enable podman.socket && systemctl start podman.socket
  2. Create a symbolic link:
    ln -s /run/podman/podman.sock /var/run/docker.sock

Change automation bridge configuration

Change the automation bridge configuration file /usr/lib/systemd/system/automation-bridge-worker@.service.

Description=Automation-bridge worker %i

ExecStart=/opt/automation-bridge/bin/automation-bridge -f /opt/automation-bridge/etc/user-configuration.conf -n %H-%i
ExecStop=/bin/kill -s TERM $MAINPID


This is the current solution and it needs to run service as root.
