- An App needs a persistent Volume tied to the Kubernetes Namespace
- Create a "pv" yaml (Example, see oom/kubernetes/aaf/charts/aaf-hello/templates/aaf-hello.pv.yaml")
- Create a "pvc" yaml (Example, see oom/kubernetes/aaf/charts/aaf-hello/templates/aaf-hello.pvc.yaml")
- Configure your Volume to your Deployment - NOTE: AS anyone dealing with HELM Charts knows, NO Tabs are allowed, and spacing is CRITICAL!!!. Use the ACTUAL helm chart, and not this summary.

volumes:
name: aaf-hello-vol
persistentVolumeClaim:
claimName: {{ .Release.Name }}-aaf-hello-pvc - In BOTH the initContainer AND your own Container, make sure you have the SAME Volume Mount
volumeMounts:
- mountPath: "/opt/app/osaaf"
name: aaf-hello-vol - Set YOUR Apps' values in "values.yaml"
# application image
service:
fqdn: "aaf-hello"
agentImage: onap/aaf/aaf_agent:2.1.15-SNAPSHOT
image: <YOUR IMAGE>
app_ns: <YOUR AAF Namespace, for "Hello", this is "org.osaaf.aaf" >
fqi: <YOUR AAF Identity, for "Hello", this is "aaf@aaf.osaaf.org" >
fqdn: <YOUR FQDN (how your App is known in K8s). This will be the main Entry for Certificate. You can add others with SAN. For "Hello", this is "aaf-hello" >
public_fqdn: <This it the PUBLIC name for the Kubernetes Cluster. For AAF's Demo, this is "aaf.osaaf.org" >
port: < This is Hello's Internal Port... configure your OWN ports accordingly "8130" >
public_port: < This is Hello's EXTERNAL Port... configure your OWN ports accordingly "31116" >
deploy_fqi: < For ONAP Envs, use the "Deployer's Identity" "deployer@people.osaaf.org" >
cadi_latitude: < Latitude of Installation (will be working on OOM to declare on Nodes) for now, anything reasonable "38.0" >
cadi_longitude: < Longitude of Installation (will be working on OOM to declare on Nodes) for now, anything reasonable "-72.0" >- Using these, your "init Container" can be:
initContainers:
- name: {{ include "common.name" . }}-config
image: {{ .Values.global.repository }}/{{.Values.service.agentImage}}
imagePullPolicy: {{ .Values.global.pullPolicy | default .Values.pullPolicy }}
volumeMounts:
- mountPath: "/opt/app/osaaf"
name: aaf-hello-vol
command: ["bash","-c","exec /opt/app/aaf_config/bin/agent.sh"]
env:
- name: APP_FQI
value: "{{ .Values.service.fqi }}"
- name: aaf_locate_url
value: "https://aaf-locate.{{ .Release.Namespace}}:8095"
- name: aaf_locator_container
value: "oom"
- name: aaf_locator_container_ns
value: "{{ .Release.Namespace }}"
- name: aaf_locator_fqdn
value: "{{ .Values.service.fqdn }}"
- name: aaf_locator_app_ns
value: "{{ .Values.service.app_ns }}"
- name: DEPLOY_FQI
value: "{{ .Values.service.deploy_fqi }}"
# Note: We want to put this in Secrets or at LEAST ConfigMaps
- name: DEPLOY_PASSWORD
value: "demo123456!"
# Note: want to put this on Nodes, evenutally
- name: cadi_longitude
value: "{{ .Values.service.cadi_longitude }}"
- name: cadi_latitude
value: "{{ .Values.service.cadi_latitude }}"
# Hello specific. Clients don't don't need this, unless Registering with AAF Locator
- name: aaf_locator_public_fqdn
value: "{{.Values.global.aaf.public_fqdn}}"
- Using these, your "init Container" can be:
- DEMO TESTS
- OOM (elalto) - use
kubectl -n onap scale --replicas=1 deployment.extensions/elalto-aaf-hello
to start the Hello Instance - Helm (in Helm, aaf-hello is a clearly separate app) - use
- helm --namespace onap -n hello install aaf-hello
- To validate, look at Logs, Container logs and/or actual Volumes
- OOM (elalto) - use
- NOTES:
- Latitude, Longitude and Public FQDN (if required) entries should be attached to actual Nodes/ENV. Will work with OOM
- DEPLOY_FQI and DEPLOY PASSWORD are more appropriate as Real-time Administrator entered "Secrets".
- ONAP's "Start from Scratch Daily" requirement makes this impossible for ONAP Test Environments. Config Maps may be more appropriate for ONAP Tests.
- Exactly how to get REAL users to use Secrets method while allowing for TESTING Automation is TBA (to be determined)
- AS STATED ABOVE, this Temporary Documentation will be moved to official "READ THE DOCS" documentation during EL ALTO.
