You can create Docker containers from the BRIDGE images using docker-compose. This includes the following steps:

Step 1: Extract the Software

Load the BRIDGE Docker image with

docker image load -i bridge-<version>.tar

Step2: Configure the Installation Settings

To configure the settings of the Docker image, you need to put your configuration in a docker-compose.yml file.

1. Create a folder to contain the BRIDGE Docker configuration.

   Please note that the docker-compose project is named after this folder, and also the created Docker containers. Naming convention for the Docker containers is: <docker-compose project name>_bridge_1.

2. Create a file docker-compose.yml to the previously created folder. This file should have the following content:

   services:
     bridge:
       image: 'bridge:${VERSION:-7.7.0}'
       hostname: '${BRIDGE_SERVER_HOSTNAME:}'
   	environment:
         - 'BRIDGE_SERVER_HOSTNAME=${BRIDGE_SERVER_HOSTNAME}'
       restart: always
       ports:
         - '${HOST_BRIDGE_PORT:-8080}:8080'
         - '${HOST_PORTS}:${CONTAINER_PORTS}'
       volumes:
         - 'bridge_data:/opt/bridge_data/'
         - './${BRIDGE_SERVER_HOSTNAME}_key.pem:/opt/bridge_data/proxies/conf/${BRIDGE_SERVER_HOSTNAME}_key.pem'
         - './${BRIDGE_SERVER_HOSTNAME}_cert.pem:/opt/bridge_data/proxies/conf/${BRIDGE_SERVER_HOSTNAME}_cert.pem'
   volumes:
     bridge_data:
       driver: local

   Here, you can change the following settings:

   Line	Setting	Description	Allowed Values / Example
   6	services/bridge/environment	Specify a proxy node name for your BRIDGE installation. You can use the environment variables ${BRIDGE_PROXY_HOSTNAME} and ${BRIDGE_SERVER_HOSTNAME}, or specify a fix filename.	a string
   			${BRIDGE_PROXY_HOSTNAME}
   			${BRIDGE_SERVER_HOSTNAME}
   7	services/bridge/restart	Define if the BRIDGE Docker container should be started automatically, e.g. on host reboot. Delete this line, if you do not want to start the container automatically. For more information on Docker restart refer to the Docker documentation pages.	always	Restart BRIDGE container on host reboot.
   13/14	services/bridge/volumes/*.pem	Mount the proxy certificate files into the container. This works with intermediate certificates as well. Copy the certificate files to the folder the docker-compose.yml resides in, or specify a valid path instead of ./. You can use the environment variables ${BRIDGE_PROXY_HOSTNAME} and ${BRIDGE_SERVER_HOSTNAME}, or specify a fix filename.

3. To define the variables used in the docker-compose.yml, create a .env file in the same folder the docker-compose.yml resides in.

   Variable	Description	Mandatory	Allowed Values / Example
   BRIDGE_SERVER_HOSTNAME	Provide your BRIDGE hostname (that matches with the BRIDGE license).		BRIDGE_SERVER_HOSTNAME='bridge.scheer-acme.com'
   BRIDGE_PROXY_HOSTNAME	Provide your BRIDGE proxy hostname (that matches with the proxy license).		BRIDGE_PROXY_HOSTNAME='proxy.scheer-acme.com'
   COMPOSE_PROJECT_NAME	Define the Docker compose project name. This name is used as a prefix for all BRIDGE volumes and containers. Once you have defined a project name and installed the BRIDGE, do not change the project name anymore.		COMPOSE_PROJECT_NAME=bridge_prod
   VERSION	Provide the version of the Docker image.		VERSION=7.8.0
   HOST_BRIDGE_PORT	Provide the BRIDGE port on the host.		HOST_BRIDGE_PORT=8090
   			Default	8080
   HOST_PORTS	Map BRIDGE Docker ports to the ports of the host. You can specify a single port or a range FROM-TO. The HOST_PORTS and CONTAINER_PORTS must have a matching count of port numbers. We recommend to route all service calls via the same proxy, so at least one more proxy mapping will be needed (as shown in the example).		HOST_PORTS=1443 HOST_PORTS=1443-1444
   CONTAINER_PORTS			CONTAINER_PORTS=443 CONTAINER_PORTS=443-444

Step 3: Start the Container

Start the container by running the following command:

docker-compose up

To run the container in the background, use:

docker-compose up -d

You can stop the container using

docker-compose stop

Step 4: Checking the Installation

If you want to check the installation, continue with Checking the Installation.
