| 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. |
| 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' |

| 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 Deployment Pod may also include a logging sidecar container. |
| The sidecar is included if .Values.logDirectory is set. The |
| logging sidecar and the DCAE microservice container share a |
| volume where the microservice logs are written. |
| |
| The Deployment includes an initContainer that pushes the |
| microservice's initial configuration (from .Values.applicationConfig) |
| into Consul. All DCAE microservices retrieve their initial |
| configurations by making an API call to a DCAE platform component called |
| the config-binding-service. The config-binding-service currently |
| retrieves configuration information from Consul. |
| |
| The Deployment also 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. |
| |
| 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. |
| |
| 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 |
