In this post i will show Tomcat Clustering in Docker Container. In  my previous post i discussed how to achieve tomcat clustering with Nginx Front end . Its almost same scenario, but this time we will achieve via docker container. Docker Docker  is an  open-source  project that automates the deployment of  applications  inside  software containers , by providing an additional layer of abstraction and automation of  operating-system-level virtualization  on  Linux . [4]  Docker uses resource isolation features of the Linux kernel  such as  cgroups  and kernel  namespaces  to allow independent "containers" to run within a single Linux instance, avoiding the overhead of starting and maintaining  virtual machine   --Wikipedia

Hi this is my fifth part of the  Tomcat Clustering Series . In this post we are going to discuss how to replace Apache httpd load balancer to Nginx as a load balancer.  [Check the video below for better understanding] Hi i finished Tomcat Clustering Series . In these series we have 2 big setups needed for Tomcat Clustering Setup and configure the Load Balancer Configure the Session Replication in Tomcat. In first setup, we configure the Load Balancer using Apache httpd web server. Its open source and widely used. Second setup is session replication in Tomcat through modify/add <cluster> tag in server.xml file. These tomcat instance may run on single machine or different machine. In our Tomcat Clustering Series , the big part is configure the Load balancer (Apache httpd web server). Because there are lots of steps are involved Install the Apache httpd web server from either source or repo Compile and install...
