Unable to successfully create jhipster project using Docker image and install instructions

Question

I am attempting to follow the official jhipster install instructions from http://jhipster.github.io/installation.html I am attempting to do the Docker install. I am using Linux Mint 17.1 and have installed docker (Docker version 1.0.1, build 990021a)

I have successfully pulled the docker container, run the container using the command provided, and ssh'd into the container.

However, when I attempt to run "yo jhipster" I run into issues. It prompts me with the standard generator questions then successfully creates all the files necessary for the project itself. Near the end of the generator, after a few of the npm installs, I end up getting an error message followed by an exception.

I'm unclear where this exception is coming from or what to do to resolve it. The official documentation doesn't mention anything about this issue, nor have I been able to locate any other reports of this exact issue.

I believe whatever is causing this exception also seems to cause issues when I try and launch the project. I use "mvn spring-boot:run" and the application appears to run, but when I try and access the webpage, I don't see any of the normal generated 'default' app I would expect. Instead, all I see is the title of the page as "jhipster" and the only text on the page itself "This is your footer"

Below is the output of the "yo jhipster" command (with some of the 'create' messages redacted for space)

Welcome to the JHipster Generator

This is an existing project, using the configuration from your .yo-rc.json file 
to re-generate the project...

create package.json

identical .gitignore
identical .gitattributes
create Gruntfile.js

I'm all done. Running bower install & npm install for you to install the required dependencies. If this fails, try running the command yourself.

Answer 1

This seems to be a bug with the JHipster Dockerfile. I submitted a pull request today in which the node version is updated. With an updated node version there is no problem anymore.

You have two options:

1. Wait for this pull request to be merged, which probably won't take more than a day or two and this will trigger an update to the JHipster Docker image on DockerHub

2. Download the Dockerfile from my forked repository and build the image yourself using the following command in the same directory as the Dockerfile

   docker build -t yourusername/jhipster-docker .
   sudo docker run -v ~/jhipster:/jhipster -p 8080:8080 -p 9000:9000 -p 35729:35729 -p 4022:22 -t yourusername/jhipster-docker 
   

This docker run command was taken from the JHipster documentation page as you mentioned before.

Answer 2

Try ">npm cache clean" and run ">yo jhipster".. it should work.

Answer 3

Have a look at these lines from the yo jhipster command

npm ERR! EEXIST, open '/home/jhipster/.npm/ebc17495-r-npm-minimist-1-1-0-   package-tgz.lock'
File exists: /home/jhipster/.npm/ebc17495-r-npm-minimist-1-1-0-package-tgz.lock
Move it away, and try again.

So delete the .lock file and try again
