app-distributed-cloud (Prototype)

This tutorial provides a step-by-step guide on containerizing DC Services using the app-distributed-cloud prototype.

Note: All dcmanager operations are not fully tested or operational.

Disable Service Management

Disable the dcmanager services on the platform

source /etc/platform/openrc

sudo sm-unmanage service dcmanager-manager
sudo sm-unmanage service dcmanager-api
sudo sm-unmanage service dcmanager-audit
sudo sm-unmanage service dcmanager-audit-worker
sudo sm-unmanage service dcmanager-orchestrator
sudo sm-unmanage service dcmanager-state

sudo sm-unmanage service dcorch-engine
sudo sm-unmanage service dcorch-engine-worker
sudo sm-unmanage service dcorch-sysinv-api-proxy
sudo sm-unmanage service dcorch-patch-api-proxy
sudo sm-unmanage service dcorch-identity-api-proxy

sudo sm-unmanage service dcdbsync-api
sudo sm-unmanage service dcagent-api

sudo pkill -f ^".*/bin/dcmanager.*"
sudo pkill -f ^".*/bin/dcorch.*"
sudo pkill -f ^".*/bin/dcdbsync.*"
sudo pkill -f ^".*/bin/dcagent.*"

Platform Setup

system host-label-assign controller-0 starlingx.io/distributed-cloud=enabled
system host-label-assign controller-1 starlingx.io/distributed-cloud=enabled

Note: If you have issues with downloading the nginx image for dc-vault-nginx, assign the distributed-cloud label just for the controller-0

Create the namespace and root-ca secret

# Create distributed-cloud namespace

kubectl create namespace distributed-cloud

# Create default-registry-key secret | if using registry.local:9001

kubectl create secret docker-registry default-registry-key \
  --docker-server=registry.local:9001 \
  --docker-username=admin \
  --docker-password=${OS_PASSWORD} \
  --namespace=distributed-cloud

# Create ca-cert secret to allow SSL

sudo cp /etc/ssl/certs/ca-certificates.crt /home/sysadmin
sudo chown sysadmin:sys_protected /home/sysadmin/ca-certificates.crt
kubectl -n distributed-cloud create secret generic root-ca   --from-file=ca.crt=/home/sysadmin/ca-certificates.crt

Distributed Cloud Application Deployment (development)

# Configure Docker Image
# Create or download the docker image used for the dcmanager pods
DOCKER_IMAGE=registry.local:9001/docker.io/starlingx/stx-distributed-cloud:master-debian-stable-latest

sudo docker login registry.local:9001

sudo docker image pull <POD_IMAGE>
sudo docker image tag <POD_IMAGE> ${DOCKER_IMAGE}
sudo docker image push ${DOCKER_IMAGE}

# Upload the prototype
system application-upload /usr/local/share/applications/helm/distributed-cloud-25.09-0.tgz

# Set Password Variables
ADMIN_KS_PASSWORD=$(keyring get CGCS admin)
RABBITMQ_PASSWORD=$(keyring get amqp rabbit)
DCMANAGER_DB_PASSWORD=$(keyring get dcmanager database)
DCMANAGER_KS_PASSWORD=$(keyring get dcmanager services)
DCORCH_DB_PASSWORD=$(keyring get dcorch database)
DCORCH_KS_PASSWORD=$(keyring get dcorch services)
DCDBSYNC_KS_PASSWORD=$(keyring get dcdbsync services)
KEYSTONE_DB_PASSWORD=$(keyring get keystone database)
DCAGENT_KS_PASSWORD=$(keyring get dcagent services)
