Run WSO2 Identity Server inside the docker container

Docker is a light weight container which runs on any computer or any cloud. It runs as an isolated process on the host operating system and its easier to create, deploy and run application. It is bit like a virtual machine, but it has different architectural approach which allow us to portable and efficient development.

You can install docker using this documentation on Linux.

Step 1 :-

You need to create a docker file. I have provided a simple docker file which use to copy identity server in to a docker image. Please copy below two lines in to a new file and modify file name as 'Docker'. I'm creating a directory 'is500image' somewhere and put this file in to that directory.

Sample Dockerfile to create a docker image with WSO2 IS 5.0.0.

FROM cogniteev/oracle-java:java7
ADD ./wso2is-5.0.0.tar.gz /opt/wso2

Step 2 :-

its better to create a tar.gz file using below commands. tar.gz file unzip its contend when its coping to docker image. You may create a file in any format, but you must be unzip the file inside the docker image.

Copy extracted wso2is-5.0.0 in to the is500image directory(which is created in first step) and execute below command.

docker build -t is500dockerimage .

This command should have a dot(.) at the end (run the command in the same directory which contained Docker file)

Step 3 :-

You can create multiple docker instances using one docker image. Use this command to run a docker instance.

docker run -i -t is500dockerimage

(docker run -i -t imageName)

When you run this command in different terminal, you can create different instances.

Important commands when you working with Docker

* If you want to stop any docker image, first you have to find the process id.

docker ps -a

(list down all docker instance)

docker ps

(list down currently running docker instance)

Then you can kill the process using below command.

docker kill CONTAINER_ID

Reverse Proxy configuration with WSO2 Identity Server 5.0.0

Reverse proxy is a type of a proxy which can hide back end servers from the client applications. According to the above figure, Original servers are not exposed to the internet. Only reverse proxy is exposed to the internet.Client knows only the reverse proxy IP address. So he thinks that he is sending a request to the reverse proxy.He doesn't know anything about the original server. You can avoid some attacks using this architecture. Today I'm going to configure Apache HTTPD server(reverse proxy) and WSO2 identity server 5.0. Please download WSO2 identity server 5.0 from here You can install apache httpd server using below commands sudo apt - get update sudo apt - get install apache2 Restart the newly install apache server sudo service apache2 restart Apache is a modular server. This implies that only the most basic functionality is included in the core server.So You have to enable few other required features. Please use below command ...

Essential Debug Logs for WSO2 Identity Server

Essential Debug loggers for WSO2 Identity Server When you are working with WSO2 products, you have to enable debug logs to investigate issues. Its better to enable debug logs only for particular module that you need to investigate. It reduce debug writing time and unnecessary debug reading time.So you can easily understand the root cause when you are reading the console.I'm going to discuss about debug lines one by one. You have to add debug line to [WSO2_HOME]\repository\conf\log4j.properties file, all debug lines are displayed in the console and write to the wso2carbon.log file. To enable loggers for user core.This is helpful to investigate user related issues. log4j.logger.org.wso2.carbon.user.core=DEBUG To enable debug logs for identity module. This debug log will be helpful to investigate identity related issues. log4j.logger.org.wso2.carbon.identity=DEBUG If you need to investigate saml assertion or assertion related issue, you ca...

Logging parameters in WSO2 ESB Script mediator

Script mediator is helpful in many ways and it can be written in different scripting languages such as JavaScript, Groovy and Ruby. I'm going t o use JavaScript for this example. I'm trying to show you the way that you can use to log some values when you are writing a mediator. This will be helpful when you need to log values when you are writing a complex script mediators. This is a sample script <script language= "js" > var log = mc.getServiceLog(); log.info( "started" ); var temp_auth = mc.getProperty('authheader'); log.info( "temp_auth : " + temp_auth); log.info( "out" ); </script> When you define a " var log = mc.getServiceLog();" variable, you can use log object to display values as below. log.info( "started" ); log.info( "temp_auth : " + temp_auth); This is a sample proxy service <?xml version= "1.0" encod...
