# 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

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

## Platform Setup

```bash
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

```bash
# Create distributed-cloud namespace

kubectl create namespace distributed-cloud

# Create system-local-ca secret

cp /etc/ssl/certs/dc-adminep-root-ca.pem /home/sysadmin/root-ca.pem

kubectl -n distributed-cloud create secret generic root-ca --from-file=ca.crt=/home/sysadmin/root-ca.pem
```

## Distributed Cloud Application Deployment (development)

```bash
# 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
```

```bash
# Set Password Variables
ADMIN_KS_PASSWORD=$(keyring get CGCS admin)

```bash
system helm-override-update distributed-cloud dcmanager distributed-cloud --values dcmanager.yaml
system helm-override-update distributed-cloud dcorch distributed-cloud --values dcorch.yaml

system helm-override-show distributed-cloud dcmanager distributed-cloud
system helm-override-show distributed-cloud dcorch distributed-cloud
```

## Apply app-distributed-cloud

```bash
system application-apply distributed-cloud
system application-show distributed-cloud
```

## To remove

```bash
system application-remove distributed-cloud
system application-delete distributed-cloud
```

## Check dcmanager endpoints

```bash
openstack endpoint list | grep dcmanager
```

## Check if dcmanager-api endpoint works

```bash
kubectl get svc dcmanager-api -n distributed-cloud
kubectl get endpoints dcmanager-api -n distributed-cloud

# Get Token
openstack token issue

curl -i http://<endpoint>/v1.0/subclouds -X GET -H "Content-Type: application/json" -H "Accept: application/json" -H "X-Auth-Token:${TOKEN}"
```

## Configure dcmanager-client

Edit file: /usr/lib/python3/dist-packages/dcmanagerclient/api/v1/client.py

```python
_DEFAULT_DCMANAGER_URL = (
    "http://dcmanager-api.distributed-cloud.svc.cluster.local:8119/v1.0"
)

# delete if not dcmanager_url: to always set default
dcmanager_url = _DEFAULT_DCMANAGER_URL
```

## Check dcmanager-manager is working

```bash
dcmanager subcloud-group add --name test
dcmanager subcloud update --group 2 subcloud2-stx-latest
```
