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.
