WebLogic Admin Tricks & Tips

We have a couple of options to create the docker images. In the last post, we got the docker installed Linux environment available. Now in this post, we will develop the Dockerfile such that it can create an image that can have Java JRE installed and WebLogic 12c installed. Lets jump on the task where we will prepare, create the Dockerfile and build the image and run the container to check all done successful. Prepare software installation Remember that official images always the preferable choice. When you search for docker images from the public repository that is hub.docker.com. We might get a huge list some of them are Automated some of them are not. The only one will be committed as an Official Image. Here selecting an image is also a strategy, logic inside. So carefully proceed further. We need to install Java Development Kit JDK latest version and WebLogic in silent mode installation. Step 1: Copy installers to data folder this is my convention I've used Here f...

In the earlier post you have seen how to use docker-compose for WebLogic images to build and also run the container with new application deployment. In this post you will be able to see the WebLogic managed servers forms cluster and the application will be deployed on top of it. Prerequisites Let me keep the list of prerequisite steps which you can follow my previous blog post or youtube video.  docker pull oraclelinux:7-slim   git clone https://github.com/oracle/docker-images.git  download server-jre1.8 latest version copy to OracleJava/dockerfiles build the image and make it as oracle/serverjre:8 download weblogic 12.2.1.2.0 quick installer which is used for development, it is small in size. image name it as oracle/weblogic:12.2.1.2-developer   create new docker images where 12212-domain:latest using WLST and shell script which are available in container scripts.  create new docker images named as 1221-appdeploy:latest where it uses 12212-doma...

Learning docker-compose for WebLogic with examples The docker-compose is one of the docker integration tool. it works based on yml or yaml file. The yml files are easy to read plain like English text. It is developed alternative to JSON files, both are used to store the key, value pairs and hierarchical structured data. To run docker-compose command in the current directory there should be  docker-compose.yml file must be exist. Prerequisites for docker-compose well awareness of docker YML syntax docker network docker-compose build with Example Dockerfile is used to build the docker image that should be present in the current directory. Create docker-compose.yml file Lets create the docker-compose.yml file for WebLogic Domain container which uses 1221-appdeploy image. The AdminServer port exposed as 7001 from the container and on left side host port opened with 7001. The container should run the command/shell script. here we can select startWebLogic.sh as start...

Writing this blog post after couple of executions experiments and research on docker. The basic requirement for docker is there must be a Linux/Unix based platform. Here I am creating that one on my Windows host machine, and the guest Ubuntu Trusty64 platform with the help of Vagrant and Oracle Virtualbox provider. vagrant Ubuntu docker - Oracle Linux images In this Article I am not dicuss about from the scratch What is docker etc. I'm not talking about Virtualization vs Containerization. Create testnode1 folder on the Windows machine. I've created on F:\testnode1. The Vagrantfile to launch Ubuntu Trusty64 Virtual machine is as follows: Vagrantfile # -*- mode: ruby -*- # vi: set ft=ruby : Vagrant.configure(2) do |config| config.vm.define "test" do |testnode1| testnode1.vm.box = "williamyeh/ubuntu-trusty64-docker" testnode1.vm.hostname="testnode1.vybhava.com" testnode1.vm.network "private_network", ip: "192.168.33...
