Hi DCAE team,
I am trying to play around with PNDA in R3 release and explore its
capabilities. I faced few issues while I am trying to integrate PNDA with
DCAEGEN2. In this mail I will try to describe the issues I faced and the
hacks I did, though I am not still able to bring up PNDA yet :)
*Keystone V3:*
There is no direct way to launch PNDA in keystone v3 only supported
openstack deployments:
*Workarounds*: In
oom/kubernetes/pnda/charts/dcae-pnda-bootstrap/resource/inputs/pnda_env.yaml
set "KEYSTONE_AUTH_VERSION" to 3. Next in pnda-bootstrap container image,
we must modify a file called "backend_heat_templates.py" which will be under*
/pnda-cli/cli/backend_heat_templates.py*. Modify the line from
auth = v3.Password(
auth_url=auth_url,
username=username,
password=password,
project_name=project_name)
to
auth = v3.Password(
auth_url=auth_url,
username=username,
password=password,
*user_domain_name="Default",*
* project_domain_name="Default",*
project_name=project_name)
*Flavors not exist:*
After the communication to openstack is working from dcae-pnda-bootstrap
container. The next step is creating the heat stack for PNDA components.
But I face the issue like flavors not exist "ec2.m4.large"
*Workarounds*: In the dcae-pnda-bootstrap container, go to
/pnda-cli/heat-templates folder and modify the flavors which exists in your
openstack environment. I think we must allow these parameters to be passed
from OOM.
*Keypair not exist:*
Similar to flavor, we must create the keypair with name "pnda" in our
openstack.
*Questions:*
*Floating IPs:*
As we are launch PNDA components in the same networks as OOM machine, why
do we need extra floating ips to communicate between pnda-bootstrap
container and PNDA VMs?
*Is Openstack Swift mandatory:*
I can see dcae-pnda heat stack created but there are some issues in
connectivity, but can you please let me know, do we need Openstack Swift
service to be installed?
Best Regards
Bharath T
