Step 2: Build your own docker file for postgres container.

So whoever building multiple layers over the postgres image, if they want to execute any other SQL commands or any, just use an ADD instruction to add your SQL files into the directory рџ™‚ДЄbove you see an SQL file, that will help to install pljava. If you look the official postgres dockerfile, you will see, it executes all the files that stay under this folder. It can be like the first command to be executed on running the container. You know what is entrypoint in docker terms вЂ“ we saw in the previous post. Why there is another folder вЂ“ docker-entrypoint-initdb.d?

You will also see other package manager run instructions. You will see the base image is from official postgres:11. You can check it from Pega official git repository It will be interesting to check the base Dockerfile right?!!. I am going to use the highest version postgres 11. If you click on the Tags, tab, there you have 3 tags (flavours) of docker image вЂ“ 9.4, 9.6 and 11. You can read more about our base image вЂ“ Note: If you choose postgres official image as the base image, then you need to add these jars in your Dockerfile. Similarly to run a pega postgres container, we somehow need to install !, Pega provided image already supports this, we donвЂ™t need to do any additional work to install it. You can find it under the installation guide вЂ“

Now think, if you need to install pega on postgres (without containers), you need to manually install it from the media file in the resource kit. So with Postgres without pljava, you cannot use these functions. PL/Java is an add-on module to Postgres that brings the Java stored procedures, triggers, and functions into Postgres database.Дo we use Java functions in pega database? вЂ“ Yes, remember the pr_read_from_stream function which is used to read the blob data from database. Step 1: Explore the right base image and tag.ДЄs I mentioned before, we will use the pegasystems/postgres-pljava-openjdk as our base image. Two main parts in this tutorial, first we will start with setting up a Postgres container and load it with our pega rule engine (necessary schemas) and then we will set up a tomcat server, connect to the Postgres and launch our Pega web application.

pegasystems/pega-ready вЂ“ for running web application in tomcat server.

pegasystems/postgres-pljava-openjdk вЂ“ for running postgres.

I am going to stick with the Pega principles вЂ“ Always reuse рџ‰ Build for change рџ™‚ So to run your Pega docker container, you can either build your image from scratch or use these official pega images. Note: Some of the images are fully baked those you can use as such and some are half baked which you can use as a base image and build your changes over.

You see they joined in 2016 and they have 8 repositories as of now and they do update the main repositories frequently with new changes рџ™‚ You can visit official pegasystems images in dockerhub. Years before Pega also started their research and published multiple images for different Pega flavors. Putting this in container terms, to run your Pega application in a docker container, you need to run two containers вЂ“ a web server вЂ“ tomcat container and a database server вЂ“ Postgres container.ДЄs soon as containerization came trending, every tech giant started their investment to make their applications container ready (mostly docker ready). A database server like Postgres to hold the entire rule base and other data.A webserver ( or an app server) like Tomcat to run the web application.

Now think, what are the minimum software need to run a Pega application? If you are a docker expert, then no need рџ‰ДЄll the commands in this post can be found the git repository вЂ“ I strongly recommend you go through all my 3 previous posts on docker for better understanding. This is the final post on docker series, where we will see how we can run a Pega docker container.
