Environment setup

Prerequisities

1. Setup TripleO http://docs.openstack.org/developer/tripleo-docs/index.html
2. install nodejs and npm sudo yum install nodejs (probably requires EPEL) In case of problems refer to https://github.com/nodejs/node-v0.x-archive/wiki/Installing-Node.js-via-package-manager#enterprise-linux-and-fedora
3. To compile and install native addons from npm you may also need to install build tools: yum install gcc-c++ make

Install and run Validations API service on Undercloud machine

Use this guide to setup and run API on Undercloud machine: https://github.com/rthallisey/clapper/blob/master/ansible-tests/README.md

Make Undercloud API services available when running app from laptop

UI requires the openstack API services to be publicly accessible.

On virt host (lab machine)

BM_NETWORK_CIDR=192.0.2.0/24
ROUTE_DEV=virbr0
SEED_IP=<UNDERCLOUD_VM_IP>
sudo ip route replace $BM_NETWORK_CIDR dev $ROUTE_DEV via $SEED_IP

On laptop

export VIRT_IP=<VIRT_HOST_IP>
export UNDERCLOUD_IP=192.0.2.1
sudo iptables -t nat -A OUTPUT -d $UNDERCLOUD_IP -j DNAT --to-destination 127.0.0.1

Copy app.conf.sample to app.conf and uncomment the lines setting keystone_url, tripleo_api_url and validations_url.

Setup ssh tunnel for OpenStack API Services

ssh stack@$VIRT_IP -L 8774:$UNDERCLOUD_IP:8774 -L 9292:$UNDERCLOUD_IP:9292 -L 8777:$UNDERCLOUD_IP:8777 -L 9696:$UNDERCLOUD_IP:9696 -L 6385:$UNDERCLOUD_IP:6385 -L 8004:$UNDERCLOUD_IP:8004 -L 5000:$UNDERCLOUD_IP:5000 -L 5001:$UNDERCLOUD_IP:5001 -L 8080:$UNDERCLOUD_IP:8080 -L 8585:$UNDERCLOUD_IP:8585 -L 35357:$UNDERCLOUD_IP:35357

Note that those ports need to be enabled in Undercloud VM's iptables (this should be already in place from undercloud installation, except for the validations API port 5001):

ssh root@<undercloud_vm_ip>
vi /etc/sysconfig/iptables

add

-A INPUT -p tcp -m tcp --dport 9696 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 8777 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 8080 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 5001 -j ACCEPT # enable Validations API port
...

below 8585 rule and restart iptables

systemctl restart iptables

Configure CORS for OpenStack services

Keystone - pastedeploy method:

ssh ssh root@<undercloud_vm_ip>
vi /usr/share/keystone/keystone-dist-paste.ini

add cors filter

[filter:cors]
paste.filter_factory = oslo_middleware.cors:filter_factory
allowed_origin=http://localhost:3000
max_age=3600
allow_methods=GET,POST,PUT,DELETE
allow_headers=Content-Type,Cache-Control,Content-Language,Expires,Last-Modified,Pragma,X-Auth-Token
expose_headers=Content-Type,Cache-Control,Content-Language,Expires,Last-Modified,Pragma

and run the filter on all pipelines like this example:

[pipeline:public_api]
# The last item in this pipeline must be public_service or an equivalent
# application. It cannot be a filter.
pipeline = cors sizelimit url_normalize request_id build_auth_context token_auth admin_token_auth json_body ec2_extension user_crud_extension public_service

and restart keystone systemctl restart openstack-keystone

Ironic - using ironic.conf

ssh root@<undercloud_vm_ip>
vi /etc/ironic/ironic.conf

add

[cors]
allowed_origin=http://localhost:3000
max_age=3600
allow_methods=GET,POST,PUT,DELETE
allow_headers=Content-Type,Cache-Control,Content-Language,Expires,Last-Modified,Pragma,X-Auth-Token
expose_headers=Content-Type,Cache-Control,Content-Language,Expires,Last-Modified,Pragma

Temporary: set auth_strategy=noauth

and restart ironic systemctl restart openstack-ironic-api

Running the App

1. git clone https://github.com/rdo-management/rdo-director-ui.git
2. cd rdo-director-ui
3. Install Gulp globally sudo npm install -g gulp
4. Install dependencies npm install
5. Serve the App gulp
6. Navigate to http://<machine_hostname>:3000/

NPM install troubleshooting

In case of errors during npm install, remove node_modules dir and clean npm cache npm cache clean. Then run npm install again.

Temporary: reqwest has a temporary issue in latest version. Downgrade to 2.0.2 to work around npm install reqwest@2.0.2. (ded/reqwest#204 (comment))

Contributing

Use GerritHub for patches and reviews (http://docs.openstack.org/infra/manual/developers.html).

1. git clone https://github.com/rdo-management/rdo-director-ui.git (if you didn't already)
2. Install git-review sudo dnf install git-review
3. Setup Gerrit by running git review -s
4. Develop on feature-branch locally
5. run git review to push patch for review.
6. Review and merge patches on GerritHub: https://review.gerrithub.io/#/q/project:rdo-management/rdo-director-ui

Tests

Single test run:

• npm test (alternatively run karma start --single-run)
• npm run lint to run ESLint
• npm test && npm run lint to run Tests and ESLint

(Info on Linting setup here: https://medium.com/@dan_abramov/lint-like-it-s-2015-6987d44c5b48, .eslintrc rules tweaks here: http://blog.javascripting.com/2015/09/07/fine-tuning-airbnbs-eslint-config/)

Style guide: https://github.com/airbnb/javascript

Tests during development:

By running gulp serve (or gulp as a shortcut), karma server is also started, and tests are run every time any .js file is saved. In case you want to explicitly run the tests, run gulp test-run.

Debugging tests

1. option:

• use console.log in the test and see the output in karma server output

2. option:

• install karma-chrome-launcher npm module npm install karma-chrome-launcher --save-dev
• replace/add 'Chrome' to browsers in karma.conf.js
• now Karma will launch Chrome to run the tests
• use debugger; statement in test code to add breakpoints
• in Karma Chrome window click 'debug' button and debug in chrome developer tools as usual
• optionally you can use karma-jasmine-html-reporter for better test output (https://www.npmjs.com/package/karma-jasmine-html-reporter)
• make sure you don't push those changes to karma.conf.js and package.json as part of your patch
