dcaegen2-services-common._ms-specific-env-vars:
This template generates a list of microservice-specific environment variables
as specified in .Values.applicationEnv. The
dcaegen2-services-common.microServiceDeployment uses this template
to add the microservice-specific environment variables to the microservice's container.
These environment variables are in addition to a standard set of environment variables
provided to all microservices.
The template expects a single argument, pointing to the caller's global context.
Microservice-specific environment variables can be specified in two ways:
1. As literal string values. (The values can also be Helm template fragments.)
2. As values that are sourced from a secret, identified by the secret's
uid and the key within the secret that provides the value.
The following example shows an example of each type. The example assumes
that a secret has been created using the OOM common secret mechanism, with
a secret uid "example-secret" and a key called "password".
applicationEnv:
APPLICATION_PASSWORD:
secretUid: example-secret
key: password
APPLICATION_EXAMPLE: "An example value"
The example would set two environment variables on the microservice's container,
one called "APPLICATION_PASSWORD" with the value set from the "password" key in
the secret with uid "example-secret", and one called "APPLICATION_EXAMPLE" set to
the the literal string "An example value".

dcaegen2-services-common._externalVolumes:
This template generates a list of volumes associated with the pod,
based on information provided in .Values.externalVolumes. This
template works in conjunction with dcaegen2-services-common._externalVolumeMounts
to give the microservice access to data in volumes created else.
This initial implementation supports ConfigMaps only, as this is the only
external volume mounting required by current microservices.
.Values.externalVolumes is a list of objects. Each object has 3 required fields and 2 optional fields:
- name: the name of the resource (in the current implementation, it must be a ConfigMap)
that is to be set up as a volume. The value is a case sensitive string. Because the
names of resources are sometimes set at deployment time (for instance, to prefix the Helm
release to the name), the string can be a Helm template fragment that will be expanded at
deployment time.
- type: the type of the resource (in the current implementation, only "ConfigMap" is supported).
The value is a case-INsensitive string.
- mountPoint: the path to the mount point for the volume in the container file system. The
value is a case-sensitive string.
- readOnly: (Optional) Boolean flag. Set to true to mount the volume as read-only.
Defaults to false.
- optional: (Optional) Boolean flag. Set to true to make the configMap optional (i.e., to allow the
microservice's pod to start even if the configMap doesn't exist). If set to false, the configMap must
be present in order for the microservice's pod to start. Defaults to true. (Note that this
default is the opposite of the Kubernetes default. We've done this to be consistent with the behavior
of the DCAE Cloudify plugin for Kubernetes [k8splugin], which always set "optional" to true.)
Here is an example fragment from a values.yaml file for a microservice:
externalVolumes:
- name: my-example-configmap
type: configmap
mountPath: /opt/app/config
- name: '{{ include "common.release" . }}-another-example'
type: configmap
mountPath: /opt/app/otherconfig
optional: false

dcaegen2-services-common.microserviceDeployment:
This template produces a Kubernetes Deployment for a DCAE microservice.
All DCAE microservices currently use very similar Deployments. Having a
common template eliminates a lot of repetition in the individual charts
for each microservice.
The template expects the full chart context as input. A chart for a
DCAE microservice references this template using:
{{ include "dcaegen2-services-common.microserviceDeployment" . }}
The template directly references data in .Values, and indirectly (through its
use of templates from the ONAP "common" collection) references data in
.Release.
The exact content of the Deployment generated from this template
depends on the content of .Values.
The Deployment always includes a single Pod, with a container that uses
the DCAE microservice image. The image name and tag are specified by
.Values.image. By default, the image comes from the ONAP repository
(registry) set up by the common repositoryGenerator template. A different
repository for the microservice image can be set using
.Values.imageRepositoryOverride. Note that this repository must not
require authentication, because there is no way to specify credentials for
the override repository. imageRepositoryOverride is intended primarily
for testing purposes.
The Deployment Pod may also include a logging sidecar container.
The sidecar is included if .Values.log.path is set. The
logging sidecar and the DCAE microservice container share a
volume where the microservice logs are written.
Deployed POD may also include a Policy-sync sidecar container.
The sidecar is included if .Values.policies is set. The
Policy-sync sidecar polls PolicyEngine (PDP) periodically based
on .Values.policies.duration and configuration retrieved is shared with
DCAE Microservice container by common volume. Policy can be retrieved based on
list of policyID or filter. An optional policyRelease parameter can be specified
to override the default policy helm release (used for retreiving the secret containing
pdp username and password)
Following is example policy config override
dcaePolicySyncImage: onap/org.onap.dcaegen2.deployments.dcae-services-policy-sync:1.0.1
policies:
duration: 300
policyRelease: "onap"
policyID: |
'["onap.vfirewall.tca","onap.vdns.tca"]'
The Deployment includes an initContainer that checks for the
readiness of other components that the microservice relies on.
This container is generated by the "common.readinessCheck.waitfor"
template. See the documentation for this template
(oom/kubernetes/common/readinessCheck/templates/_readinessCheck.tpl).
If the microservice uses a DMaaP Data Router (DR) feed, the Deployment
includes an initContainer that makes provisioning requests to the DMaaP
bus controller (dmaap-bc) to create the feed and to set up a publisher
and/or subscriber to the feed. The Deployment also includes a second
initContainer that merges the information returned by the provisioning
process into the microservice's configuration. See the documentation for
the common DMaaP provisioning template
(oom/kubernetes/common/common/templates/_dmaapProvisioning.tpl).
If the microservice acts as a TLS client or server, the Deployment will
include an initContainer that retrieves certificate information from
the AAF certificate manager. The information is mounted at the
mount point specified in .Values.certDirectory. If the microservice is
a TLS server (indicated by setting .Values.tlsServer to true), the
certificate information will include a server cert and key, in various
formats. It will also include the AAF CA cert. If the microservice is
a TLS client only (indicated by setting .Values.tlsServer to false), the
certificate information includes only the AAF CA cert.
If the microservice uses certificates from an external CMPv2 provider,
the Deployment will include an initContainer that performs certificate
post-processing.
