JHipster

What is JHipster

JHipster generates (scaffolds) a complete Java backend / Web Frontend project based on answering a few configuration option questions.

Scripts

docker run script

the run script has no options and will

1. pull the jhipster docker image (only once)
2. run the jhipster docker container (only once)
3. restart the jhipster docker container (if not running)

example

./run
found 0 jhipster image(s)
pulling jhipster image
Using default tag: latest
latest: Pulling from jhipster/jhipster
32802c0cfa4d: Pull complete

run

#!/bin/bash
# WF 2018-12-26
# see https://www.jhipster.tech/installation/

# how many jhipster images have been installed?
# check how many lines the image command creates
imagecount=$(docker images jhipster/jhipster | wc -l)
#REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

# substract the repository line
imagecount=$(($imagecount-1))
echo "found $imagecount jhipster image(s)"
# if there is no image yet - get it
if [ $imagecount -eq 0 ]
then
  echo "pulling jhipster image"
  docker image pull jhipster/jhipster
fi

if [ ! -d $jhipsterhome ]
then
  echo "creating $jhipsterhome"
  mkdir $jhipsterhome

then
  echo "running jhipster container"
  docker container run --name jhipster -v ~/jhipster:/home/jhipster/app -v ~/.m2:/home/jhipster/.m2 -p 8080:8080 -p 9000:9000 -p 3001:3001 -d -t jhipster/jhipster
