Creating Your Own Bridge Docker Image
To install the Bridge you can use the Docker image delivered by us but you can also create a BRIDGE Docker image of your own to fulfill special needs. You can do this from scratch, or you can use the delivered Bridge Docker image and change it according to your needs.
The Bridge Docker image is built in two steps:
Creation of a Debian basic image containing an Oracle and an SQL Server instant client.
Creation of the actual Bridge image on base of the Debian basic image.
Required Files to Create a Bridge Docker Image
If you want to create the Bridge Docker image you need the following files:
File | In ZIP | Usage |
|---|---|---|
Dockerfile Debian Basic |
| The Docker file that rules the build of a Debian Basic image. |
Dockerfile Bridge |
| The Docker file that rules the build of a Bridge image on base of the Debian Basic image. |
BridgeInstaller-linux-64-x.x.x.jar |
| A Bridge installer. |
guilessinstaller.properties |
| A properties file for GUI-less installation. |
proxies.xml |
| A file containing proxy definitions. You need it only if you use sudo. |
server.cfg |
| A file containing the configuration for MySQL and SQL Server client libraries. |
sudo_httpd |
| A file containing sudo and httpd configurations. |
You can download a ZIP archive containing all files that are marked with In ZIP from our download page.
The Debian Basic Docker File Explained
In a first step, a Debian basic image is created that is used later on as a base for the actual Bridge image. Expand the code section below to see and copy & paste the Docker file.

The Bridge Docker File Explained
In a second step, the actual Bridge image is created on base of the previously created Debian basic image. Expand the code section below to see and copy & paste the Docker file.
