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

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

126 {{- $opt := hasKey $vol "optional" | ternary $vol.optional true }}

139 dcaegen2-services-common._externalVolumeMounts:
140 This template generates a list of volume mounts for the microservice container,
141 based on information provided in .Values.externalVolumes. This
142 template works in conjunction with dcaegen2-services-common._externalVolumes
143 to give the microservice access to data in volumes created else.
144 This initial implementation supports ConfigMaps only, as this is the only
145 external volume mounting required by current microservices.

166 dcaegen2-services-common.microserviceDeployment:
167 This template produces a Kubernetes Deployment for a DCAE microservice.
169 All DCAE microservices currently use very similar Deployments. Having a
170 common template eliminates a lot of repetition in the individual charts
171 for each microservice.
173 The template expects the full chart context as input. A chart for a
174 DCAE microservice references this template using:
175 {{ include "dcaegen2-services-common.microserviceDeployment" . }}
176 The template directly references data in .Values, and indirectly (through its
177 use of templates from the ONAP "common" collection) references data in
180 The exact content of the Deployment generated from this template
181 depends on the content of .Values.
183 The Deployment always includes a single Pod, with a container that uses
184 the DCAE microservice image. The image name and tag are specified by
185 .Values.image. By default, the image comes from the ONAP repository
186 (registry) set up by the common repositoryGenerator template. A different
187 repository for the microservice image can be set using
188 .Values.imageRepositoryOverride. Note that this repository must not
189 require authentication, because there is no way to specify credentials for
190 the override repository. imageRepositoryOverride is intended primarily
191 for testing purposes.
193 The Deployment Pod may also include a logging sidecar container.
194 The sidecar is included if .Values.log.path is set. The
195 logging sidecar and the DCAE microservice container share a
196 volume where the microservice logs are written.
198 Deployed POD may also include a Policy-sync sidecar container.
199 The sidecar is included if .Values.policies is set. The
200 Policy-sync sidecar polls PolicyEngine (PDP) periodically based
201 on .Values.policies.duration and configuration retrieved is shared with
202 DCAE Microservice container by common volume. Policy can be retrieved based on
203 list of policyID or filter. An optional policyRelease parameter can be specified
204 to override the default policy helm release (used for retreiving the secret containing
205 pdp username and password)
207 Following is example policy config override
209 dcaePolicySyncImage: onap/org.onap.dcaegen2.deployments.dcae-services-policy-sync:1.0.1
212 policyRelease: "onap"
214 '["onap.vfirewall.tca","onap.vdns.tca"]'
216 The Deployment includes an initContainer that checks for the
217 readiness of other components that the microservice relies on.
218 This container is generated by the "common.readinessCheck.waitfor"
219 template. See the documentation for this template
220 (oom/kubernetes/common/readinessCheck/templates/_readinessCheck.tpl).
222 If the microservice uses a DMaaP Data Router (DR) feed, the Deployment
223 includes an initContainer that makes provisioning requests to the DMaaP
224 bus controller (dmaap-bc) to create the feed and to set up a publisher
225 and/or subscriber to the feed. The Deployment also includes a second
226 initContainer that merges the information returned by the provisioning
227 process into the microservice's configuration. See the documentation for
228 the common DMaaP provisioning template
229 (oom/kubernetes/common/common/templates/_dmaapProvisioning.tpl).
231 If the microservice acts as a TLS client or server, the Deployment will
232 include an initContainer that retrieves certificate information from
233 the AAF certificate manager. The information is mounted at the
234 mount point specified in .Values.certDirectory. If the microservice is
235 a TLS server (indicated by setting .Values.tlsServer to true), the
236 certificate information will include a server cert and key, in various
237 formats. It will also include the AAF CA cert. If the microservice is
238 a TLS client only (indicated by setting .Values.tlsServer to false), the
239 certificate information includes only the AAF CA cert.
241 If the microservice uses certificates from an external CMPv2 provider,
242 the Deployment will include an initContainer that performs certificate
