Full feature setup:

• Dependency analysis
• jBPM server

PNC is delivered as JEE EAR package that can be deployed to EAP / WildFly or other JEE application server.

JEE Server requirements:

• JBoss EAP/Wildfly Adapter
• Hibernate as JPA provider
• PostgreSQL JDBC driver

Requirements

• JDK 8
• Maven 3.2
• Java IDE (IntelliJ IDEA community recommended)
  • code style template: https://github.com/project-ncl/ide-config

REST API documentation and testing

OpenAPI api doc is available via any OpenAPI viewer using this spec http://hostname/pnc-rest/v2/openapi.json

*Requires running instance of PNC

The default build is executed by running mvn clean install.

The default build does not run "integration tests" annotated with @ContainerTest. Tests annotated with @DebugTest are also skipped by default as they are usually written to run against a remote running server.

To run container tests use profile -Pcontainer-tests. Extra parameter -Deap6.zip.url is required to provide the location of server distribution archive. Tests requiring JEE application server (tested with JBoss EAP 7.0).

Example:

mvn clean install -Pcontainer-tests -Deap.zip.url=file:///home/development/jboss-eap.zip

To run debug tests use -Pdebug-tests.

By default it is required to specify install phase to run container tests.

To use verify phase append property -DuseTargetBuilds (no value required) to use artifacts generated during package phase in target folder.

Application server is installed by default to folder target in project top level folder. During installation additional modules (HSQL, Postgresql JDBC drivers, datasources, RHSSO) required to run integration tests are installed into the server.

To run only installation of application server to specific folder use -Dtest.server.unpack.dir=.

Example to install server to /tmp folder:

mvn clean verify -Pcontainer-tests -Deap6.zip.url=SERVER_ZIP_URL -pl :test-common,:test-arquillian-container -Dtest.server.unpack.dir=/tmp

1. Install application server (see Installing application server for integration tests manually)

2. start the server

   sh /tmp/jboss-eap/bin/standalone.sh

3. run integration tests with additional system properties and excluded module test-arquillian-container

   -Darq.container.wf.configuration.jbossHome=/tmp/jboss-eap -Darq.container.wf.configuration.allowConnectingToRunningServer=true -pl !:test-arquillian-container

   mvn clean verify -Pcontainer-tests -pl !:test-arquillian-container -Deap6.zip.url= -DuseTargetBuilds -Darq.container.wf.configuration.jbossHome=/tmp/jboss-eap -Darq.container.wf.configuration.allowConnectingToRunningServer=true

1. Install application server (see Installing application server for integration tests manually)

2. start the server

   sh /tmp/jboss-eap/bin/standalone.sh

3. Create new Run/Debug configuration of type Arquillian JUnit

• setup arquillian container - Click button Configure in Arquillian Container tab, add 'Manual container configuration', add 'Maven dependency' in dependencies, type in text field org.jboss.as:jboss-as-arquillian-container-managed:7.2.0.Final

• select test class or package or module in Configuration tab

• specify path to application server and allow to connect to running server in VM options:

  -Darq.container.wf.configuration.jbossHome=/tmp/jboss-eap -Darq.container.wf.configuration.allowConnectingToRunningServer=true

• optionally append following properties (no value required) to VM options: -DcreateArchiveCopy - to write ear deployed by arquillian to project folder (eg. for content inspection) -DuseTargetBuilds - to use artifact generated by package phase in target folder

Property useTargetBuilds can be used together with configuration 'Run maven goal' mvn package -DskipTests=true in 'before lunch' tab to deploy code changes without actual need to run mvn clean install

A Maven profile called production is provided to configure the appropriate settings to build a deployment file which is compatible with the postgresql database.

mvn install -Pproduction

TODO: this is not working currently, integration tests are always run against HSQLDB The container tests can also be run against postgresql by activating the container-tests profile, and the production profile.

mvn install -Pproduction,container-tests

All configurations are centralized in the configuration file moduleconfig/src/main/resources/pnc-config.json.

You can copy the file to external location and specify the location via -Dpnc-config-file=/path/to/pnc-config.json parameter.

Or you can configure the app using the environment variables listred in the file.

For the configuration descriptions see api doc of classes in moduleconfig/src/main/java/org/jboss/pnc/common/json/moduleconfig

If you want to specify the ThreadPool size for PollingMonitor, you can do so by using the system property polling_monitor_threadpool.

For example, you can specify via -Dpolling-monitor-threadpool=10 parameter

You can also specify the environment variable polling_monitor_threadpool.

Note that the system property has precedence over the environment variable if both are defined.

You will need to download the hsqldb jar file and copy the jar file into the standalone/deployments directory of your JBoss server. Check the server log to see that the driver deployed successfully.

From the EAP/Wildfly admin console, select Configuration-->Connector-->Datasources. Click the "Add" button to add a new datasource and set the required fields.

Name: NewcastleTestDS
JNDI Name: java:jboss/datasources/NewcastleTestDS
JDBC Driver: hsqldb-2.3.3.jar
Connection URL: jdbc:hsqldb:mem:newcastletestmemdb

You can test the connection before saving the datasource settings. Finally, enable the datasource, and it is ready to be used by the newcastle application.

Basic installation instructions for Postgres on recent versions of Fedora can be found on the Fedora wiki: https://fedoraproject.org/wiki/PostgreSQL

(Optional) In addition to the postgresql server, it's useful to install the gui admin tool pgadmin3 (dnf install pgadmin3).

Once postgresql is installed and started, you can create and modify the databases using the psql command.

Connect to postgres

$ psql -h localhost newcastle -U <ROOT_USERNAME>

Create the user "newcastle Create user

postgres=# CREATE USER newcastle WITH PASSWORD newcastle;

Create the newcastle database Create newcastle database

postgres=# CREATE DATABASE newcastle OWNER newcastle;

Once the database is created, the schema can be built using the SQL files included with the newcastle source code, or it can be created automatically if it doesn't exist.

You will need to download and install the PostgreSQL JDBC driver into Wildfly (https://jdbc.postgresql.org/download.html). Copy the postgresql jdbc driver jar into the standalone/deployments directory of your JBoss server. Check the server log to see whether the driver deployed successfully.

From the EAP/Wildfly admin console, select Configuration-->Connector-->Datasources. Click the "Add" button to add a new datasource and set the required fields.

Name: NewcastleDS
JNDI Name: java:jboss/datasources/NewcastleDS
JDBC Driver: postgresql-9.3.jar
Connection URL: jdbc:postgresql://localhost:5432/newcastle
Username: newcastle
Password: newcastle

You can test the connection before saving the datasource settings.

This project comes with possibility to be secured. Security is delivered via Keycloak project http://keycloak.jboss.org/. To be able to turn on whole project on secure side you need 2 parts to fulfill.

1. Have running and configured Keycloak server instance.
   
2. Build & configure security for your PNC installation.

PRE-REQUIREMENTS:

Install your Keycloak server standalone or in Openshift according to

• http://keycloak.github.io/docs/userguide/html/server-installation.html.
• http://keycloak.github.io/docs/userguide/html/openshift.html

Configure Keycloak server

1. Create your realm By default the Keycloak server comes with "master realm", which is for demo purpose, so please create your own realm.

HINTS

Configure keycloak subsystem secure-deployment in EAP/wildfly stanbdalone.xml

1. pncrest additional props -> use these below for skipping ssl & defining rest for accepting only access_token for authentication/authorization.

• "ssl-required": "none",
• "bearer-only" : true,

2. pncweb additional props -> look at http://keycloak.github.io/docs/userguide/html/ch08.html#adapter-config to find more about adapter's config.

• "ssl-required" : "none",
• "use-resource-role-mappings" : false,
• "enable-basic-auth" : false,
• "enable-cors" : true,
• "cors-max-age" : 1000,
• "cors-allowed-methods" : "POST,PUT,DELETE,GET",
• "bearer-only" : false,

By default PNC project comes with no security at all, it is up to you to turn it on. In case you want to enable authentication use -Pauth together with your build command. Enabling authentication means following

1. Your backend REST endpoints will become secured

• rest.war will use the web.xml with security-constraints & security-roles (rest/src/main/webconfig/auth/web.xml)

2. Your pnc web UI gain the SSO ability and authentication via Keycloak login page.

• with your first unauthenticated session you will be redirected from pnc web UI into Keycloak login page.
• you will be asked to provide your credentials.
• after successful log-in you will be redirected back to pnc web UI.

3. Configure your JEE server (EAP) for keycloak

• Use -Dauth.eap.home=<path to your EAP installation> with you build command, if you want EAP configure for Keycloak. According the http://docs.jboss.org/keycloak/docs/1.1.0.Final/userguide/html/ch08.html#jboss-adapter-installation installation will be performed on server for the given path.

Before running the PNC you have to update the pnc-config.json and set "authenticationProviderId" to "Keycloak" instead of the default "JAAS" if you want to use Keycloank authentication.

PNC is using OpenShift to provide clean build environmtn for each build. You can override the pod definitions used to configure the build-agent pod via pnc configuration:

{
  "@module-group": "pnc",
  "configs": [
      {
        "@module-config": "openshift-build-agent",
          "pncBuilderPod": {...},
          "pncBuilderService": {...},
          "pncBuilderRoute": {...},
          "pncBuilderSshRoute": {...}
      },
      ...
  ]

You only need to define the key for which you want to modify its definition. There is no need to define all the keys.

PNC tracks metrics of JVM and its internals via Dropwizard Metrics. The metrics can currently be reported to a Graphite server by specifying as system property or environment variables those properties:

• metrics_graphite_server (mandatory)
• metrics_graphite_port (mandatory)
• metrics_graphite_prefix (mandatory)
• metrics_graphite_interval (optional)

If the metrics_graphite_interval variable (interval specified in seconds) is not specified, we'll use the default value of 60 seconds to report data to Graphite.

The graphite reporter is configured to report rates per second and durations in terms of milliseconds.
