[Airship-discuss] [airship-discuss] Error when changing simple parameters for AIAB?

[SKELS, KASPARS]

Hi Nick,

I think you may need to look into the AIAB scripts to see more if changing the region name may impact the changes in actual deployment scripts/assumptions of AIAB. It is definitely the right idea but then on the other hand AIAB are sort of demo/development case with various assumptions/simplifications to make it possible to do a single touch deployment in a single VM - without any user input.

I would suggest to poke around and initially try some config changes that may have lesser impact on the system as a whole. The particular variable, region_name is definitely possible to change, for example see Seaworthy deployment https://github.com/airshipit/treasuremap/blob/master/site/seaworthy/software/config/common-software-config.yaml#L15 .

I think simple visible things could be updating pod replicas or logging levels of OpenStack components to start with.

For example Heat
https://github.com/airshipit/treasuremap/blob/master/site/aiab/software/charts/osh/openstack-heat/heat.yaml<https://github.com/airshipit/treasuremap/blob/master/site/aiab/software/charts/osh/openstack-compute-kit/nova.yaml>
You may add replica part to the site manifests (borrowed from type)
https://github.com/airshipit/treasuremap/blob/master/type/sloop/charts/osh/comps/heat.yaml#L18

For all the available variables you can change for Heat or any component will be in values.yaml in openstack-helm project, including OpenStack image that can be changed and overridden for chart deployment (in case you have a custom build)
https://opendev.org/openstack/openstack-helm/src/branch/master/heat/values.yaml#L42

There is also another way to update site deployments with config changes, without full re-deploy, that is when site is running (day 2 operations)

Kindly, Kaspars

So i was able to deploy Airship in a Bottle, albeit on a much larger machine (but that's a separate issue).  I wanted to demonstrate how the manifests control things, so I started up a fresh VM and edited /root/deploy/treasuremap/site/aiab/software/config/common-software-config.yaml to change the region name:

I then went ahead and ran the script as usual, but it was unable to deploy/find Horizon.  To make sure that the change was the issue, I then went and created a THIRD fresh VM and ran it without the change, and it deployed successfully.

Is this expected?

To duplicate:


sudo -i

mkdir -p /root/deploy && cd "$_"

git clone https://opendev.org/airship/treasuremap/<https://urldefense.proofpoint.com/v2/url?u=http-3A__opendev.org_airship_treasuremap_&d=DwMFaQ&c=LFYZ-o9_HUMeMTSQicvjIg&r=L2WcX1Ge33cpIHXX6krAgw&m=i7XiFhmUk7_iab0NprdyhgeYbBuzyviytv6_co_GVYs&s=wE686gobeMCRbv5J_45OiKOp9F1UR9O0UiPofZlHnZY&e=>

cd /root/deploy/treasuremap/tools/deployment/aiab/

Then

Edit :~/deploy/treasuremap/site/aiab/software/config/common-software-config.yaml


---

schema: pegleg/CommonSoftwareConfig/v1

metadata:

  schema: metadata/Document/v1

  name: common-software-config

  layeringDefinition:

    abstract: false

    layer: site

  storagePolicy: cleartext

data:

  osh:

    region_name: ThisIsMyRegion

...

Then
./airship-in-a-bottle.sh

If someone can recommend a value that I could successfully change as a demonstration, I would really appreciate it.

Thanks!
