WildFly, formerly known as JBoss AS or JBoss, is an application server authored by JBoss, now developed by Red Hat. WildFly is written in Java and implements the Java Platform, Enterprise Edition (Java EE) specification. It runs on multiple platforms.

Prerequisite

  1. Add the following in kubernetes YAML file, in the containers section:

    	command: ["/opt/jboss/wildfly/bin/standalone.sh"]
	args: ["-b", "0.0.0.0", "-bmanagement" ,"0.0.0.0"]

  2. For Virtual machines, install the Linux agent.

Configuration

Do the following configuration tasks.

Configure credentials

Configure the credentials in the /opt/opsramp/agent/conf/app.d/creds.yaml directory:

wildfly:
- name: wildfly
  user: <username>
  pwd: <Password>
  encoding-type: plain
  labels:
    key1: val1
    key2: val2

Virtual machine

Configure the application in the directory /opt/opsramp/agent/conf/app/discovery/auto-detection.yaml

- name: wildfly
  instance-checks:
    service-check:
      - wildfly
    process-check:
      - wildfly
    port-check:
      - 8080
      - 9990

Docker environment

Configure the application in the directory /opt/opsramp/agent/conf/app/discovery/auto-container-detection.yaml

- name: wildfly
  container-checks:
    image-check:
      - wildfly
    port-check:
      - 8080
      - 9990

Kubernetes environment
