Sample Docker configurations to facilitate installation, configuration, and environment setup for DevOps users. This project includes quick start dockerfiles and samples for WebLogic 12.1.3, 12.2.1, 12.2.1.1 and 12.2.1.2 based on Oracle Linux and Oracle JDK 8 (Server).
The certification of WebLogic on Docker does not require the use of any file presented in this repository. Customers and users are welcome to use them as starters, and customize/tweak, or create from scratch new scripts and Dockerfiles.
For more information on the certification, please check the WebLogic on Docker Certification Whitepaper and WebLogic Blog for updates.
For pre-built images containing Oracle software, please check the Oracle Container Registry.
This project offers sample Dockerfiles for WebLogic 12cR2 (12.2.1.x) and WebLogic 12c (12.1.3), and for each version it also provides at least one Dockerfile for the 'developer' distribution and a second Dockerfile for the 'generic' distribution, as well more if necessary. To assist in building the images, you can use the buildDockerImage.sh script. See below for instructions and usage.
The buildDockerImage.sh script is just a utility shell script that performs MD5 checks and is an easy way for beginners to get started. Expert users are welcome to directly call docker build with their prefered set of parameters.
You must first download the Oracle Server JRE binary and drop in folder ../OracleJava/java-8 and build that image. For more information, visit the OracleJava folder's README file.
$ cd ../OracleJava/java-8
$ sh build.sh
IMPORTANT: you have to download the binary of WebLogic and put it in place (see .download files inside dockerfiles/).
Before you build, choose which version and distribution you want to build an image of, then download the required packages (see .download files) and drop them in the folder of your distribution version of choice. Then go into the dockerfiles folder and run the buildDockerImage.sh script as root.
$ sh buildDockerImage.sh -h
Usage: buildDockerImage.sh -v [version] [-d | -g | -i] [-s]
Builds a Docker Image for Oracle WebLogic.
Parameters:
-v: version to build. Required.
Choose one of: 12.1.3 12.2.1
-d: creates image based on 'developer' distribution
-g: creates image based on 'generic' distribution
-i: creates image based on 'infrastructure' distribution
-c: enables Docker image layer cache during build
-s: skips the MD5 check of packages
* select one distribution only: -d, -g, or -i

IMPORTANT: the resulting images will NOT have a domain pre-configured. You must extend the image with your own Dockerfile, and create your domain using WLST. You might take a look at the use case samples as well below.
To give users an idea on how to create a domain from a custom Dockerfile to extend the WebLogic image, we provide a few samples for 12c versions for the Developer distribution. For an example on 12.2.1, you can use the sample inside samples/1221-domain folder. For the 12.1.3 version, check the folder samples/1213c-domain.
This Dockerfile will create an image by extending oracle/weblogic:12.2.1-developer. It will configure a base_domain with the following settings:
- Admin Username:
weblogic - Admin Password: provided by
ADMIN_PASSWORD - Oracle Linux Username:
oracle - Oracle Linux Password:
welcome1 - WebLogic Domain Name:
base_domain - Admin Server on port:
7001 - NodeManager on port:
5556 - Managed Server on port:
7002
Make sure you first build the WebLogic 12.2.1 Image with -d to get the Developer Image.
The best way to create your own, or extend domains is by using WebLogic Scripting Tool. You can find an example of a WLST script to create domains at create-wls-domain.py. You may want to tune this script with your own setup to create DataSources and Connection pools, Security Realms, deploy artifacts, and so on. You can also extend images and override an existing domain, or create a new one with WLST.
To try a sample of a WebLogic image with a domain configured, follow the steps below:
-
Make sure you have oracle/weblogic:12.2.1-developer image built. If not go into dockerfiles and call
$ sh buildDockerImage.sh -v 12.2.1 -d
-
Go to folder samples/1221-domain
-
Run the following command:
$ docker build -t 1221-domain --build-arg ADMIN_PASSWORD= .
-
Verify you now have this image in place with
$ docker images
To start the WebLogic AdminServer, you can simply call docker run -d 1221-domain command. The sample Dockerfile defines startWebLogic.sh as the default CMD.
$ docker run -d --name=wlsadmin -p 7001:7001 1221-domain
Now you can access the AdminServer Web Console at http://localhost:7001/console.
WebLogic has a Machine concept, which is an operational system with an agent, the Node Manager. This resource allows WebLogic AdminServer to create and assign Managed Servers of an underlying domain in order to expand an environment of servers for different applications and resources, and also to define a Cluster. By using Machines from containers, you can easily create a Dynamic Cluster by simply firing new NodeManagers containers. With some WLST magic, your cluster can scale in and out.
You can deploy a cluster of WebLogic using Docker with the samples scripts defined in this repository. After you have an AdminServer running on a container as per above, you can easily create a cluster by deploying new Docker containers of Managed Servers. To do that, first make sure you have an AdminServer containerized with name wlsadmin. Then you can fire the following command:
$ docker run -d --link wlsadmin:wlsadmin 1221-domain createServer.sh
Wait 5-10 seconds, and then go into the AdminServer Web Console and check in the Machines page if the NodeManager was registered. Then check if the Managed Server was also created and registered. The script createServer.sh starts a NodeManager inside the container and then it will also create a Managed Server, and register both on the Admin Server located at wlsadmin as per the alias indicated.
By using the sample samples/1221-multihost, which contains a set of scripts that leverage Docker Machine and Docker Swarm, and by digging through the scripts that create the containers across multiple hosts combined with the scripts inside 1221-domain/container-scripts, you can learn the necessary steps to deploy this with different Docker setups.
The basic idea behind this setup is that you must have all the containers across different hosts assigned to a specific Docker Overlay Network, a feature of Docker 1.9+ that allows containers to join the same network, even though they are running at different host environments.
The Supplemental Quick Installer is a lightweight installer that contains all of the necessary artifacts to develop and test applications on Oracle WebLogic Server 12.2.1. You can extend the WebLogic developer install image oracle/weblogic:12.2.1-developer to create a domain image with the MedRec application deployed.
-
Make sure you have
oracle/weblogic:12.2.1-developerimage built. If not go into dockerfiles and call$ sh buildDockerImage.sh -v 12.2.1 -d
-
Go to folder samples/1221-medrec
-
Download into this folder the supplemental package for WebLogic 12R2
-
Run the following command:
$ docker build -t 1221-medrec .
-
Now run a container from this new sample domain image
$ docker run -ti -p 7002:7002 1221-medrec
-
Now access the AdminServer Console at
This project hosts two to three configurations (depending on WebLogic version) for building Docker images with WebLogic 12c.
