Setup Development for Micronaut and GraalVM

Introduction

In this lab you will take a fresh OCI compute instance and set it up for development for an application that uses Micronaut, ATP and GraalVM.

Estimated Lab Time: 10 minutes

Objectives

In this lab you will:

• SSH into a remote VM
• Install git, GraalVM and Micronaut

Prerequisites

• Followed the Setup OCI lab
• An OCI compute instance setup with RSA keys installed
• The compute instance has the ATP wallet setup and installed

Setup Development Machine

1. Use SSH to access your Development Compute Instance. You have a choice: connect to your compute instance from Cloud Shell or from your local terminal.

   ssh -i ~/.ssh/local_id_rsa opc@${COMPUTE_IP}

2. Setup the Compute Instance by installing the software needed to run this lab.

   Install Git:

   sudo yum install -y git
   git --version

   Install GraalVM: Use Graal Enterprise https://docs.oracle.com/en/graalvm/enterprise/20/guide/overview/oci/create-instance.html

   sudo yum -y install graalvm20-ee-11-20.2.0-1.el7.x86_64
   sudo yum -y install graalvm20-ee-11-native-image
   
   java -version

   Make sure the version number of the java command that is on the path is the one that was installed:

   java 11.0.8.0.2 2020-07-09 LTS
   Java(TM) SE Runtime Environment GraalVM EE 20.2.0 (build 11.0.8.0.2+1-LTS-jvmci-20.2-b03)
   Java HotSpot(TM) 64-Bit Server VM GraalVM EE 20.2.0 (build 11.0.8.0.2+1-LTS-jvmci-20.2-b03, mixed mode, sharing)

   Install SDKMAN:

   curl -s https://get.sdkman.io | bash
   source "$HOME/.sdkman/bin/sdkman-init.sh"

   Install Micronaut:

   sdk install micronaut
   mn --version
   

   Note: This is a small chance this doesn't work in which case you can bypass using sdk manager:

   wget https://github.com/micronaut-projects/micronaut-starter/releases/download/v2.0.0/micronaut-cli-2.0.0.zip
   
   unzip micronaut-cli-2.0.0.zip
   
   rm micronaut-cli-2.0.0.zip
   echo 'export PATH=/home/opc/micronaut-cli-2.0.0/bin:$PATH' >> ~/.bashrc
   
   source ~/.bashrc
   mn --version

   Make sure the version number of the mn command that is on the path is the one that was installed:

   Micronaut Version: 2.0.0
   JVM Version: 11.0.8.0.2
   

   Install Gradle:

   sdk install gradle
