Payara Micro s2i Builder for OpenShift

The s2i-payara-micro builder simplifies build, configuration and deployment of ThinWARs in cloud native environments like OpenShift and docker.

Getting started

The s2i-payara-micro inherits from the payara-micro-s2i and indirectly java8-s2i docker images from Docklands. The base CentOS 7 operating system, Java and Payara 5 are inherited.

Instead of building the universe, s2i-payara-micro configures the Payara 5 server using stock pre-boot scripts, copies 3rd-party libraries like e.g. JDBC-drivers and deploys a ThinWAR from the local folder.

Also checkout the thin.war example.

Payara configuration

Create a asadmin-preboot or asadmin-postboot scripts to configure the application server: https://docs.payara.fish/documentation/payara-micro/asadmin/pre-and-post-boot-scripts.html

Building the builder

The build is based on Payara Micro 5 s2i base image from docklands, published to dockerhub airhacks/payara-micro-s2i:5.192.

1. Clone https://github.com/AdamBien/docklands.git
2. cd java/java8-s2i/ and docker build -t airhacks/java-s2i .
3. cd payara-micro-s2i and docker build -t airhacks/payara-micro-s2i:5.192

Now build the builder:

1. git clone https://github.com/AdamBien/s2i-payara-micro
2. docker build -t airhacks/s2i-payara-micro .

Installing on OpenShift

1. Import the image into an image stream: oc import-image s2i-payara-micro --from=airhacks/s2i-payara-micro:latest --confirm
2. Create an app from the imported image: oc new-app s2i-payara-micro:latest~/. --name=thinwar
3. Start a build: oc start-build --from-dir . thinwar from a directory with the following contents:
