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. +*/}} + +{{- define "dcaegen2-services-common.microserviceDeployment" -}} +{{- $logDir := default "" .Values.logDirectory -}} +{{- $certDir := default "" .Values.certDirectory . -}} +{{- $tlsServer := default "" .Values.tlsServer -}} +apiVersion: apps/v1 +kind: Deployment +metadata: {{- include "common.resourceMetadata" . | nindent 2 }} +spec: + replicas: 1 + selector: {{- include "common.selectors" . | nindent 4 }} + template: + metadata: {{- include "common.templateMetadata" . | nindent 6 }} + spec: + initContainers: + - command: + - sh + args: + - -c + - | + {{- range $var := .Values.customEnvVars }} + export {{ $var.name }}="{{ $var.value }}";
