Jelastic - Application configuration

Application configuration

The Configuration Manager gives you access to the home directory and your environment's configuration files. Use the Configuration Manager to specify any additional settings that your application needs.

To run the Configuration Manager, click on your environment's Config button for the needed node (app server, database, nginx, memcached or maven):

The list of configuration folders will be opened. Here you can make all your settings.

Application Server Configuration
Database Configuration
Cron Configuration
NGINX Balancer Configuration
Maven Configuration
Memcached Configuration

A. Application Server Configuration

The following app server configuration files are available:

Software stack	Supported configuration files
Tomcat 6	server.xml, catalina.properties, tomcat-users.xml, context.xml, web.xml

TomEE	server.xml, catalina.properties, tomcat-users.xml, context.xml, web.xml, tomee.xml, system.properties

If you have several application servers you can configure them separately. To do this use the drop-down menu at the top of the configuration tab. It includes the list of all your servers.

Choose the one you need and make the configurations.
To apply the changes:

only for the chosen server click Save only for current instance button from drop-down menu;
for all the servers click Save.

Among all available configurations you can also set scheduled backups of your database using the instructions in the Scheduling Database Backups document.

MongoDB configuration files include keys directory to which you can upload any private key which is needed for your application.

Generate the key, save it as a simple file and upload to the key folder.
Now you can use it for different cases just stating the path to your key:
