From the base directory run these commands:

1. make build-base
2. docker-compose build

NB: To run Kilda, you should have built it already (ie the previous section). This is particularly important because docker-compose will expect some of the containers to already exist.

From the base directory run these commands:

1. docker-compose up

or

1. make up-test-mode

From the base directory run these commands:

1. make build-floodlight
2. make run-floodlight

Start with the following

1. '''make unit'''

From there, you can go to specific projects to build / develop / unit test. Just follow the make unit trail. Most projects have a maven target.

NB: Several projects have a dependency on the maven parent; look at make unit

Look in the base/hacks/usecase directory and you'll find several makefiles that will assist with the development and testing of that use case.

As an example, you can execute the following command for more information on the network discovery use case:

make -f base/hacks/usecase/network.disco.make help

# or

cd base/hacks/usecase
make -f network.disco.make help

VirtualBox and Vagrant are popular options for creating VMs. A VM may be your best bet for doing development with Kilda. There are a set of files in the source tree that will facilitate this.

• NB1: Ensure you have VirtualBox and Vagrant installed and on the path
• NB2: You'll re-clone kilda so that there aren't any write permission issues between the guest VM and the host.

Steps:

1. From the root directory, look at the Vagrantfile; feel free to change its parameters.
2. vagrant up - create the VM; it'll be running after this step.
3. vagrant ssh - this will log you into the vm.
4. ssh-keygen -t rsa -C "[email protected]" - you'll use this for GitHub. Press for each question; three in total.
5. Add the ~/.ssh/id-rsa.pub key to your GitHub account so that you can clone kilda

cat ~/.ssh/id_rsa.pub

6. Clone and Build

# NB: Instead of putting it in vm-dev, you can use /vagrant/vm-dev
#     This has the added benefit that the code will appear outside the VM
#     i.e. /vagrant is shared with the same directory as the Vagrantfile
git clone [email protected]:<your_github_account>/open-kilda.git vm-dev
cd vm-dev
git checkout mvp1rc
make build-base
docker-compose build
make unit
make up-test-mode
make atdd

We have ansible playbook for managing config/properties files from templates which is placed in templates/ folder. This playbook contains three files with variables. One for default options (like endpoints, all defaults should be here): templates/defaults/main.yaml and second one for paths of template and destinations: templates/vars/path.yaml and last one for overriding defaults: templates/vars/vars.yaml

For now default options are the same which was before this playbook implementation and suitable for docker-compose build.

Pre-requirements: You have to add localhost ansible_connection=local to /etc/ansible/hosts

1. create and place jinja template file to templates/templates/ folder
2. add it to templates/vars/path.yaml
3. change (if needed) vars in templates/defaults/main.yaml
4. run: make update-props-dryrun for checking that template behaviour is ok
5. run: make update-props for applying templates

1. Add new vars, edit: templates/defaults/main.yaml
2. If you need override default vars, edit: templates/vars/vars.yaml
3. run: make update-props-dryrun for checking that template behaviour is ok
4. run: make update-props for applying templates

An exmaplte, you already have neo4j server, and want to use it instead of dockerized neo4j. You can add neo4j endpoints to templates/defaults/main.yaml and create properties template for services which use neo4j:

templates/defaults/main.yaml:

neo4j_host: "neo4j"
neo4j_user: "neo4j"
neo4j_password: "temppass"

templates/templates/topology-engine/topology_engine.properties.j2:

[kafka]
consumer.group=python-tpe-tl-consumer
topology.topic={{ kafka_topic }}
bootstrap.servers={{ kafka_hosts }}

[gevent]
worker.pool.size=1024

[zookeeper]
hosts={{ zookeeper_hosts }}

[neo4j]
host={{ neo4j_host }}
user={{ neo4j_user }}
pass={{ neo4j_password }}

templates/vars/path.yaml:

  - topology_engine_properties:
    dest: services/topology-engine/queue-engine/topology_engine.properties
    tmpl: templates/topology-engine/topology_engine.properties.j2

In this example we will generate file services/topology-engine/queue-engine/topology_engine.properties from template templates/topology-engine/topology_engine.properties.j2

Someone with admin rights should log in using github account to https://travis-ci.org and on the page https://travis-ci.org/profile/telstra activate telstra/open-kilda repository. All configurations for travis are located in .travis.yml. For adding new scripts you should create new line under script parameter.

script:
- make run-test
