1.background
The previous document mentioned how to separate the UUI server with postgres and connect the database
on the docker.
Now we use the previously created images UUI server: 1 and Postgres: 14.4 to integrate them into the oom
environment of ONAP.
First, you need to understand the knowledge of oom and the basic operations of k8s and helm.
2.pre-knowledge
OOM requires local k8s and helm environments.
Please refer to the offiffifficial documents for specifific installation
https://docs.onap.org/projects/onap-oom/en/latest/oom_quickstart_guide.html#oom-quickstart-guide
The use of helm can be learned from the offiffifficial documents
The common helm commands are:
#helm repository
helm repo list
helm repo update
helm search repo onap
#install and uninstall
helm install
helm uninstall
#deploy & undeploy （
helm plugins)
helm deploy ...
helm undeploy ...
Since helm 3 does not have a server, there is a way to create the helm local warehouse chartuseum in the
installation document of oom.
3.Specifific implementation
fifirst , we git clone oom.
current branch have not been merged.
git fetch "https://gerrit.onap.org/r/oom" refs/changes/92/129992/6 && git checkout -b
change-129992-6 FETCH_HEAD
The code to be modifified is in the directory of oom/kubernetes/uui/components
You can see other components of UUI: uui-server, uui-postgres, and uui-intent analysis
You need to add the initialization statement of uui-server to uui-postgres and connect the UUI server to uui
postgres.
The directory structure of uui-server 、uui-postgres、uui-intent-analysisserver is as follows:
3.1 uui-postgres/templates/confifigmap.yaml
Modify confifigmap.yaml is used to confifigure the database and write the initialization command of the
database.
Add at the end of the fifile
3.2 uui-server/values.yaml
service.name values in uui-postgres/values.yaml
add values in uui-server/values.yaml below
Note: keep postgres.name=uui-postgres.service.name , or uui-server cannot connect postgres
modify the image version of uui-server
image: onap/usecase-ui-server:latest
3.3 uui-server/templates/deployment.yaml
Add a parameter in the env fifield
Note : All labels in yaml must be of type string
(MSB_ADDR and MR_ADDR are also injected here and need not be modifified)
3.4 Copy the previously modifified applications.properties and run.sh
confifig/applications.properties
entrypoint/run.sh
So far, the submitted online environment has been modifified.
4.offlfflffline debug
For offlfflffline debugging, we need to modify some confifigurations before it can run. The modifified content is
commented out in the following code
4.1uui-server/values.yaml
4.2 uui-server/templates/deployment.yaml
4.3 run make
run command in dir oom/kubernetes
4.4 run uui
As can be seen from the above command, after Postgres is started, the UUI server does not report the
database connection error. It started normally. The database is connected!
In the local environment, since no probe is added and the service is started after the database is started, the
server may not be able to connect to the database for the fifirst time. The corresponding pod needs to be
deleted.
kubectl delete uui-uui-server-74fb68fdcd-clxcd -n uuisee the new server pod started to run successfully
5.follow-up work
Subsequently, we need to standardize the database connection mode of oom, that is, add probes, etc
