CONGA - Usage
Make sure you have installed:
- Java 8 or higher
- Apache Maven 3.3 or higher
Example project can be found at: https://github.com/wcm-io-devops/conga/tree/develop/tooling/conga-maven-plugin/src/it/example
CONGA differentiates between role/template definitions and environment definitions. Although it is possible to put them all together into one single Maven project it is recommended to separate them, because they are usually maintained by separated people, see general concepts.
In this example they are separated, start with building the definitions:
cd definitions mvn clean install
This produces an maven artifact
io.wcm.devops.conga.example.definitions-1-SNAPSHOT.jar which is installed in the local maven repository as well. It contains role definitions and file templates. It is recommended to deploy it to a central maven repository within your organization.
The role files can be found in
src/main/roles, you can also see there what configuration parameters are possible and what are their default values.
The file templates are located at
src/main/templates in folders per role. They are written using the Handlebars scripting language.
To build the real configuration files switch go to the environments folder:
cd environments mvn clean package
This builds all configuration files for all nodes defined in the environment files. The definitions from the previous step are referenced as maven dependency.
You find the generated files at
target/configuration, they are packed as well in a ZIP file located at
target. Those files can be uploaded to the destination system (ideally in an automated fashion by using a deployment automation tool).
Using from command line
It is possible to use CONGA outside Maven from the command line using this prepackaged JAR with all dependencies:

This mode lacks some features like building definition artifacts, versioning etc. So it is recommended to use the Maven plugin whenever possible.
