Gateway configuration

The gateway commands are located in a dedicated folder:

├── activate.sh
├── bin
│   ├── channelctl
│   ├── commons-lib.sh
│   ├── hjson-manager
│   ├── punchlinectl
│   ├── punchplatform-analytics-scan.sh
│   ├── punchplatform-env.sh
│   ├── punchplatform-lib.sh
│   ├── punchplatform-pyspark-scan.sh

│   ├── log4j2-sparkctl.properties
│   ├── log4j2-sparkctl.xml

In addition the the various command internally required bu the gateway, this folder also contains logger configuration files, and and two punch platform level configuration files resolv.hjson and punchplatform.properties generated at deployment time.

Gateway binaries

The binaries and libraries (i.e. executable) files are provided in a separate folder. These are provided by a punch uber binary package named punchplatform-binaries-*. The punch deployer install it on each punch node. Here is its layout:

punchplatform-binaries-6.1.0/
├── apache-storm-2.1.0
├── lib
│   ├── spark/
│   ├── pyspark/
│   ├── storm/
│   ├── punchplatform-command-cli-6.1.0-jar-with-dependencies.jar
│   ├── punchplatform-gateway-app-6.1.0.jar
│   ├── punchplatform-log-injector-6.1.0-jar-with-dependencies.jar
│   ├── punchplatform-monitoring-service-6.1.0-jar-with-dependencies.jar
│   ├── punchplatform-puncher-6.1.0-jar-with-dependencies.jar
│   ├── punchplatform-shiva-app-6.1.0-jar-with-dependencies.jar
│   └── ...
├── logstash-7.4.2
├── resources
└── spark-2.4.3-bin-hadoop2.7

As you can see this folder contains both the punchplatform-gateway-app-*.jar required to run the gateway itself, and the punchplatform-command-cli-*-jar-with-dependencies.jar library required by the gateway to execute punch commands.
