This Docker image prepares an Oracle WebLogic Server (a developer desktop licensed version of WebLogic Server) image for development purposes by creating a sample domain preconfigured to run Pega applications.

The following instructions are for building the WebLogic Proprietary information hidden.0 Pega Docker image using Linux.

Datasource and JMS resources are automatically configured according to the Pega Platform Installation Guide for Oracle WebLogic Server using the datasource.properties file.

You can find the Pega Platform Installation Guide for Oracle WebLogic Server for your Pega platform version here: https://community.pega.com/knowledgebase/products/platform

Pega archives placed in the /pega/deploy directory are automatically deployed.
Split-Schema installations are supported using Pega 7 deployment plan.

The domain name is base_domain

Pega 7 platform versions supported

• Pega 7.3
• Pega 7.3.1
• Pega 7.4

Build Prerequisites

Download the following prerequisites and copy them to the directory where the Docker build file (Dockerfile) is stored.

• Oracle WebLogic Server Proprietary information hidden.0 - Generic Installer (developer desktop licensed version) WebLogic Download Page
• Oracle Java JDK 8u171 - 64-bit RedHat package Java Download Page

Run Prerequisites

A database with the Pega rulebase must be installed and connected to the Docker container.

Volumes

At runtime, the image exposes the following mount point as volumes:

/pega

Ports

The admin server listens to port 7001. This port can be exposed and mapped to a different host port while running the container for the first time.

WebLogic Console

WebLogic Console app is reachable at ip_address:<mapped_port>/console

Domain admin credentials are: weblogic/Pegasys1+

Note: you can change the password by providing a different one in the ADMIN_PASSWORD variable when the container is run. For example:

- e 'ADMIN_PASSWORD=my_password'

Build

$ docker build -t prpc_wls:12.2.1 .

Run

Prepare the datasource

Edit the datasource.properties file and provide the JDBC connection details. The following datasource.oracle.properties Oracle based sample is placed in pega/etc

datasource.name=PegaRules

datasource.database.name=PEGA

datasource.target=AdminServer

datasource.filename=PegaRules.xml

datasource.jndiname=jdbc/PegaRULES

datasource.driver.class=oracle.jdbc.OracleDriver

datasource.url=jdbc:oracle:thin:@oradb:1521/pega

datasource.username=PEGA_DATA

datasource.password=PEGA

datasource.pool.initialSize=10

datasource.pool.maxSize=60

datasource.test.query=SQL SELECT 1 FROM DUAL

The docker --link run option can be used to reference the database container using an alias. In the above sample (datasource.url=jdbc:oracle:thin:@oradb:1521/pega) the database alias oradb is referenced in the JDBC URL and must be provided at runtime in this way:

--link <db_container_name>:oradb

Prepare the host directories

Create the expected folder structure in your system.

The local pega directory can be used as a template.

/pega

Within this directory the following directories are expected:

/deploy

Place the archives to be automatically deployed at runtime in this directory.

/etc

Place the datasource configuration file and the standard Pega configuration files in this directory. The standard Pega configuration files are:

* datasource.properties

* adminDatasource.properties (optional)

* prbootstrap.properties

* prconfig.xml

* prlogging.xml

* prlog4j2.xml

/tmp

This will be used as Pega temporary directory

/logs

This directory is assigned to the ${pega.log.location} environment variable. Ensure that the prlogging.xml or prlog4j2.xml file (the file to use depends on the logging configuration selected) is updated to include this variable in file paths.

/lib

Place here the JDBC driver referenced by the -e DRIVER= run option

Run command

Run WebLogic in interactive mode using as_wls1221_ora_740 as host and container name, exposing port 7741, linking a database container db-pega-740 using the db alias, using the JDBC driver dbdriver.jar, mounting the host path obtained via bash command $(pwd) on the container volume /pega

$ docker run -it -p 7740:7001 -h as_wls1221_ora_740 --name=as_wls1221_ora_740 \

--link db-pega-740:db \

-v $(pwd):/pega \

-e 'DRIVER=dbdriver.jar' \

-e 'USER_MEM_ARGS=-Xms2048m -Xmx4096m -XX:MetaspaceSize=256m -XX:MaxMetaspaceSize=1024m -XX:ReservedCodeCacheSize=256m -XX:+UseCodeCacheFlushing' \

- e 'ADMIN_PASSWORD=my_password' \

prpc_wls:12.2.1

More details about the used arguments:

Dual-User Configuration

The Admin Datasource is required to automatically apply DML statements to the Pega Schemas.

Note: To inform Pega about the Admin Datasource availability, the following environment entries are required.

prconfig/database/databases/PegaRULES/dataSourceAdmin

prconfig/database/databases/PegaDATA/dataSourceAdmin

These string entries must contain the JNDI name of the Admin Datasource(s). Since WebLogic doesn't allow to add custom entries to the JNDI tree the Application Deployment Descriptors must be used instead.

The deployment plan in /pega/deploy/prpc/plan takes care of providing values for those entries.

Stopping a running container

Attach an interactive console to the container.
This is not required if you run the container with the -i option:

$ docker attach --sig-proxy=true Container_Name

Press CTRL+C to stop the container.

Starting an existing container

$ docker start -i -a <Container_Name>

Attached are the files from my sample. I hope this is useful to you!
