Usage

Clone this repository and cd into it.

Create a virtualenv and install prerequisites:

$ virtualenv -p $(which python3) venv
$ . venv/bin/activate
$ pip install -r requirements.txt

Then run the following commands:

$ vagrant up
$ vagrant ssh-config

Based on the following template, create the inventory/hosts inventory file and fill it in with values for parameters HostName, Port and IdentityFile outputted by the last command:

cloudkitty-playground ansible_user=vagrant ansible_host=<IP-from-HostName> ansible_port=<number-from-Port> ansible_private_key_file=<path-from-IdentityFile>

Note

You will need to update the inventory each time you destroy the AIO VM with vagrant destroy and then create it again with vagrant up.

Confirm you are all set up by running:

$ ansible -i inventory/ all -m shell -a "hostname"

TODO: Find a method to generate Ansible inventories for Vagrant boxes automatically.

Next up, create this symlink (or move/copy the kolla subdirectory to /etc/) on your deploy host and deploy the OpenStack AIO with kolla-ansible:

$ sudo ln -s $(pwd)/kolla /etc/kolla
$ kolla-genpwd
$ kolla-ansible -vv -i inventory/ bootstrap-servers
$ kolla-ansible -vv -i inventory/ deploy
Note

Config files for all the deployed OpenStack services can be found in the /etc/kolla/ directory inside the Vagrant machine.

When the deploy is done, run these commands to create some basic OpenStack resources:

$ kolla-ansible -vv -i inventory/ post-deploy
$ source /etc/kolla/admin-openrc.sh
$ wget https://opendev.org/openstack/kolla-ansible/raw/branch/stable/train/tools/init-runonce
$ EXT_NET_CIDR='172.20.20.0/24' EXT_NET_RANGE='start=172.20.20.100,end=172.20.20.200' EXT_NET_GATEWAY='172.20.20.1' bash init-runonce

Now you can create a test instance and SSH into it to confirm the environment is fully functional:

$ openstack server create --image cirros --flavor m1.tiny --key-name mykey --network demo-net demo1
$ eval $(openstack floating ip create public1 -f shell | grep ^floating_ip_address)
$ openstack server add floating ip demo1 ${floating_ip_address}
$ openstack server list
$ ssh cirros@${floating_ip_address}
Note

You may need to wait a few seconds before SSH on the instance becomes available.

Note

The Horizon dashboard URL is http://10.10.10.254.

To confirm CloudKitty is available, run this command on your deploy host:

$ openstack rating summary get

This should return an empty list.

Replacing CloudKitty containers with host virtualenvs

For Cloudkitty testing and development it might be more convenient to work with CloudKitty installed in a virtualenv on the host rather than in containers.

$ vagrant ssh
$ sudo yum install python3 python3-devel gcc git vim -y
$ curl https://bootstrap.pypa.io/get-pip.py | sudo python3 -
$ pip3 install virtualenv==20.2.1
$ git clone https://opendev.org/openstack/cloudkitty
$ cd cloudkitty/
$ git checkout stable/train
$ virtualenv -p $(which python3) venv
$ . venv/bin/activate
$ pip install --upgrade pip
$ pip install -r requirements.txt
$ pip install pymysql==0.10.1 python-memcached==1.51 # these modules are needed but not listed in requirements
$ pip install Werkzeug==0.16.1 # the latest version (1.0.1) no longer supports the "DispatcherMiddleware()" method
$ python setup.py install
$ sudo mkdir -p /opt/cloudkitty/log
$ sudo chown -R $USER /opt/cloudkitty/

To replace the cloudkitty_processor container follow these steps:

$ sudo cat /etc/kolla/cloudkitty-processor/cloudkitty.conf | tee /opt/cloudkitty/cloudkitty.conf
$ sudo cat /etc/kolla/cloudkitty-processor/metrics.yml | tee /opt/cloudkitty/metrics.yml
Note

Sample metrics.yml files can be found on collector-specific branches in this repository.

Adjust paths for the following config parameters found in /opt/cloudkitty/cloudkitty.conf:

sed -i.$(date +%s).bak 's|\(^log_dir = \).*|\1/opt/cloudkitty/log|' /opt/cloudkitty/cloudkitty.conf #`log_dir = /opt/cloudkitty/log` in section `[DEFAULT]`
sed -i.$(date +%s).bak 's|\(^lock_path = \).*|\1/opt/cloudkitty/tmp|' /opt/cloudkitty/cloudkitty.conf #`lock_path = /opt/cloudkitty/tmp` in section `[oslo_concurrency]`
sed -i.$(date +%s).bak 's|\(^metrics_conf = \).*|\1/opt/cloudkitty/metrics.yml|' /opt/cloudkitty/cloudkitty.conf #`metrics_conf = /opt/cloudkitty/metrics.yml` in section `[collect]`

Also, remove or comment out log_file if present. Finally, start the service:

$ sudo docker stop cloudkitty_processor
$ . venv/bin/activate
$ $(which cloudkitty-processor) --config-file /opt/cloudkitty/cloudkitty.conf

Processor logs will be written to /opt/cloudkitty/log/cloudkitty-processor.log.

To replace the cloudkitty_api container follow these steps:

$ sudo cat /etc/kolla/cloudkitty-api/cloudkitty.conf | tee /opt/cloudkitty/cloudkitty.conf
$ sudo docker exec cloudkitty_api cat /etc/cloudkitty/api_paste.ini | tee /opt/cloudkitty/api_paste.ini

Adjust paths for the following config parameters found in /opt/cloudkitty/cloudkitty.conf:

sed -i.$(date +%s).bak 's|\(^log_dir = \).*|\1/opt/cloudkitty/log|' /opt/cloudkitty/cloudkitty.conf #`log_dir = /opt/cloudkitty/log` in section `[DEFAULT]`
sed -i.$(date +%s).bak 's|\(^lock_path = \).*|\1/opt/cloudkitty/tmp|' /opt/cloudkitty/cloudkitty.conf #`lock_path = /opt/cloudkitty/tmp` in section `[oslo_concurrency]`

Also, remove or comment out log_file if present. Finally, start the service:

$ sudo docker stop cloudkitty_api
$ . venv/bin/activate
$ $(which cloudkitty-api) --host 10.10.10.254 --port 8889 -- --config-file /opt/cloudkitty/cloudkitty.conf
Note

The port number and the host IP have to be passed through flags even if they are specified again in the [api] section of cloudkitty.conf.

API logs will be written to /opt/cloudkitty/log/cloudkitty-api.log.

Finding CloudKitty data in Influx

Run these commands to check out what data CloudKitty has collected so far in its InfluxDB database:

$ sudo docker exec -it influxdb influx -host 10.10.10.254 -database cloudkitty
> SHOW MEASUREMENTS
> SELECT * FROM dataframes ORDER BY time DESC LIMIT 10
