This post will cover deploying a Talend ESB RESTful service as a OSGI Bundle for ESB in Talend runtime environment on Ubuntu server.
sudo apt-get install openjdk-7-jdk
Environment variable JAVA_HOME must be set because Talend Runtime will first look out for Java installation.
Execute below command to find out alternative Java path.
sudo update-alternatives --config java
Select path of preferred installation and update environment file by adding below code.
sudo vi /etc/environment
Reload file and Test
I am using FileZilla to send Runtime_ESBSE to Ubuntu server after compressing it, but server directory must have required permission to copy Runtime_ESBSE.zip file.
Use chmod to give sufficient permissions.
sudo chmod 777 -R etl
Install unzip to extract Runtime_ESBSE on server.
sudo apt-get update
sudo apt-get install unzip
Execute trun command to launch Runtime environment.
On Runtime container use list command to check status of your service.
we can also verify by hitting API endpoint using CURL
curl -i -H "Accept: application/json"
-H "Content-Type: application/json"
Now we are able to deploy ESB job as service in Talend Runtime container using apache karaf but to make it run as a operating system service we must install Karaf Wrapper feature.
Installing the wrapper
- Browse to the container/bin folder of the Talend Runtime installation directory, then launch the container by executing the trun file as a root user
- To install the wrapper feature, simply type:
karaf@trun()> feature:install wrapper
Once installed, wrapper feature will provide
wrapper:install new command in the trun, which allows you to install Talend Runtime as a service.
- To register the container as a service in automatic start mode, simply type:
karaf@trun()> wrapper:install -s AUTO_START -n talend
-d Talend -D "Talend ESB Runtime Service"
To install the service:
$ ln -s /dev/etl/talend/Runtime_ESBSE/container/bin/talend-service /etc/init.d/
To start the service when the machine is rebooted:
$ update-rc.d talend-service defaults
To disable starting the service when the machine is rebooted:
$ update-rc.d -f talend-service remove
To start the service:
$ /etc/init.d/talend-service start
To stop the service:
$ /etc/init.d/talend-service stop
To uninstall the service :
$ rm /etc/init.d/talend-service
