# First steps with Constellation
|
|
|
|
The following steps guide you through the process of creating a cluster and deploying a sample app. This example assumes that you have successfully [installed and set up Constellation](install.md).
|
|
|
|
## Create a cluster
|
|
|
|
1. Create the configuration file for your selected cloud provider.
|
|
|
|
<tabs groupId="csp">
|
|
<tabItem value="azure" label="Azure">
|
|
|
|
```bash
|
|
constellation config generate azure
|
|
```
|
|
|
|
</tabItem>
|
|
<tabItem value="gcp" label="GCP">
|
|
|
|
```bash
|
|
constellation config generate gcp
|
|
```
|
|
|
|
</tabItem>
|
|
</tabs>
|
|
|
|
This creates the file `constellation-conf.yaml` in your current working directory.
|
|
|
|
2. Fill in your cloud provider specific information.
|
|
|
|
<tabs groupId="csp">
|
|
<tabItem value="azure" label="Azure (CLI)">
|
|
|
|
You need several resources for the cluster. You can use the following `az` script to create them:
|
|
|
|
```bash
|
|
RESOURCE_GROUP=constellation # enter name of new resource group for your cluster here
|
|
LOCATION=westus # enter location of resources here
|
|
SUBSCRIPTION_ID=$(az account show --query id --out tsv)
|
|
SERVICE_PRINCIPAL_NAME=constell
|
|
az group create --name "${RESOURCE_GROUP}" --location "${LOCATION}"
|
|
az group create --name "${RESOURCE_GROUP}-identity" --location "${LOCATION}"
|
|
az ad sp create-for-rbac -n "${SERVICE_PRINCIPAL_NAME}" --role Owner --scopes "/subscriptions/${SUBSCRIPTION_ID}/resourceGroups/${RESOURCE_GROUP}" | tee azureServiceAccountKey.json
|
|
az identity create -g "${RESOURCE_GROUP}-identity" -n "${SERVICE_PRINCIPAL_NAME}"
|
|
identityID=$(az identity show -n "${SERVICE_PRINCIPAL_NAME}" -g "${RESOURCE_GROUP}-identity" --query principalId --out tsv)
|
|
az role assignment create --assignee-principal-type ServicePrincipal --assignee-object-id "${identityID}" --role 'Virtual Machine Contributor' --scope "/subscriptions/${SUBSCRIPTION_ID}"
|
|
az role assignment create --assignee-principal-type ServicePrincipal --assignee-object-id "${identityID}" --role 'Application Insights Component Contributor' --scope "/subscriptions/${SUBSCRIPTION_ID}"
|
|
echo "subscription: ${SUBSCRIPTION_ID}
|
|
tenant: $(az account show --query tenantId -o tsv)
|
|
location: ${LOCATION}
|
|
resourceGroup: ${RESOURCE_GROUP}
|
|
userAssignedIdentity: $(az identity show -n "${SERVICE_PRINCIPAL_NAME}" -g "${RESOURCE_GROUP}-identity" --query id --out tsv)
|
|
appClientID: $(jq -r '.appId' azureServiceAccountKey.json)
|
|
clientSecretValue: $(jq -r '.password' azureServiceAccountKey.json)"
|
|
```
|
|
|
|
Fill the values produced by the script into your configuration file.
|
|
|
|
By default, Constellation uses `Standard_DC4as_v5` CVMs (4 vCPUs, 16 GB RAM) to create your cluster. Optionally, you can switch to a different VM type by modifying **instanceType** in the configuration file. For CVMs, any VM type with a minimum of 4 vCPUs from the [DCasv5 & DCadsv5](https://docs.microsoft.com/en-us/azure/virtual-machines/dcasv5-dcadsv5-series) or [ECasv5 & ECadsv5](https://docs.microsoft.com/en-us/azure/virtual-machines/ecasv5-ecadsv5-series) families is supported.
|
|
|
|
Run `constellation config instance-types` to get the list of all supported options.

|
|
|
|
* **subscription**: The UUID of your Azure subscription, e.g., `8b8bd01f-efd9-4113-9bd1-c82137c32da7`.
|
|
|
|
You can view your subscription UUID via `az account show` and read the `id` field. For more information refer to [Azure's documentation](https://docs.microsoft.com/en-us/azure/azure-portal/get-subscription-tenant-id#find-your-azure-subscription).
|
|
|
|
* **tenant**: The UUID of your Azure tenant, e.g., `3400e5a2-8fe2-492a-886c-38cb66170f25`.
|
|
|
|
You can view your tenant UUID via `az account show` and read the `tenant` field. For more information refer to [Azure's documentation](https://docs.microsoft.com/en-us/azure/azure-portal/get-subscription-tenant-id#find-your-azure-ad-tenant).
|
|
|
|
* **location**: The Azure datacenter location you want to deploy your cluster in, e.g., `westus`. CVMs are currently only supported in a few regions, check [Azure's products available by region](https://azure.microsoft.com/en-us/global-infrastructure/services/?products=virtual-machines®ions=all). These are:
|
|
|
|
* `westus`
|
|
* `eastus`
|
|
* `northeurope`
|
|
* `westeurope`
|
|
|
|
* **resourceGroup**: [Create a new resource group in Azure](https://learn.microsoft.com/azure/azure-resource-manager/management/manage-resource-groups-portal) for your Constellation cluster. Set this configuration field to the name of the created resource group.
|
|
|
|
* **userAssignedIdentity**: [Create a new managed identity in Azure](https://learn.microsoft.com/azure/active-directory/managed-identities-azure-resources/how-manage-user-assigned-managed-identities). You should create the identity in a different resource group as all resources within the cluster resource group will be deleted on cluster termination.
|
|
|
|
Add two role assignments to the identity: `Virtual Machine Contributor` and `Application Insights Component Contributor`. The `scope` of both should refer to the previously created cluster resource group.
|
|
|
|
Set the configuration value to the full ID of the created identity, e.g., `/subscriptions/8b8bd01f-efd9-4113-9bd1-c82137c32da7/resourcegroups/constellation-identity/providers/Microsoft.ManagedIdentity/userAssignedIdentities/constellation-identity`. You can get it by opening the `JSON View` from the `Overview` section of the identity.
|
|
|
|
The user-assigned identity is used by instances of the cluster to access other cloud resources.
|
|
For more information about managed identities refer to [Azure's documentation](https://docs.microsoft.com/en-us/azure/active-directory/managed-identities-azure-resources/how-manage-user-assigned-managed-identities).
|
|
|
|
* **appClientID**: [Create a new app registration in Azure](https://learn.microsoft.com/azure/active-directory/develop/quickstart-register-app).
|
|
|
|
Set `Supported account types` to `Accounts in this organizational directory only` and leave the `Redirect URI` empty.
|
|
|
|
Set the configuration value to the `Application (client) ID`, e.g., `86ec31dd-532b-4a8c-a055-dd23f25fb12f`.
|
|
|
|
In the cluster resource group, go to `Access Control (IAM)` and set the created app registration as `Owner`.
|
|
|
|
* **clientSecretValue**: In the previously created app registration, go to `Certificates & secrets` and create a new `Client secret`.
|
|
|
|
Set the configuration value to the secret value.
|
|
|
|
* **instanceType**: The VM type you want to use for your Constellation nodes.
|
|
|
|
For CVMs, any type with a minimum of 4 vCPUs from the [DCasv5 & DCadsv5](https://docs.microsoft.com/en-us/azure/virtual-machines/dcasv5-dcadsv5-series) or [ECasv5 & ECadsv5](https://docs.microsoft.com/en-us/azure/virtual-machines/ecasv5-ecadsv5-series) families is supported. It defaults to `Standard_DC4as_v5` (4 vCPUs, 16 GB RAM).
|
|
|
|
Run `constellation config instance-types` to get the list of all supported options.
|

<tabItem value="gcp" label="GCP (CLI)">
|
|
|
|
You need a service account for the cluster. You can use the following `gcloud` script to create it:
|
|
|
|
```bash
|
|
SERVICE_ACCOUNT_ID=constell # enter name of service account here
|
|
PROJECT_ID= # enter project id here
|
|
SERVICE_ACCOUNT_EMAIL=${SERVICE_ACCOUNT_ID}@${PROJECT_ID}.iam.gserviceaccount.com
|
|
gcloud iam service-accounts create "${SERVICE_ACCOUNT_ID}" --description="Service account used inside Constellation" --display-name="Constellation service account" --project="${PROJECT_ID}"
|
|
gcloud projects add-iam-policy-binding "${PROJECT_ID}" --member="serviceAccount:${SERVICE_ACCOUNT_EMAIL}" --role='roles/compute.instanceAdmin.v1'
|
|
gcloud projects add-iam-policy-binding "${PROJECT_ID}" --member="serviceAccount:${SERVICE_ACCOUNT_EMAIL}" --role='roles/compute.networkAdmin'
|
|
gcloud projects add-iam-policy-binding "${PROJECT_ID}" --member="serviceAccount:${SERVICE_ACCOUNT_EMAIL}" --role='roles/compute.securityAdmin'
|
|
gcloud projects add-iam-policy-binding "${PROJECT_ID}" --member="serviceAccount:${SERVICE_ACCOUNT_EMAIL}" --role='roles/compute.storageAdmin'
|
|
gcloud projects add-iam-policy-binding "${PROJECT_ID}" --member="serviceAccount:${SERVICE_ACCOUNT_EMAIL}" --role='roles/iam.serviceAccountUser'
|
|
gcloud iam service-accounts keys create gcpServiceAccountKey.json --iam-account="${SERVICE_ACCOUNT_EMAIL}"
|
|
echo "project: ${PROJECT_ID}
|
|
serviceAccountKeyPath: $(realpath gcpServiceAccountKey.json)"
|
|
```
|
|
|
|
Fill the values produced by the script into your configuration file.
|
|
|
|
By default, Constellation uses `n2d-standard-4` VMs (4 vCPUs, 16 GB RAM) to create your cluster. Optionally, you can switch to a different VM type by modifying **instanceType** in the configuration file. Supported are all machines from the N2D family. Refer to [N2D machine series](https://cloud.google.com/compute/docs/general-purpose-machines#n2d_machines) or run `constellation config instance-types` to get the list of all supported options.
|
|
|
|
</tabItem>
|
|
<tabItem value="gcp-console" label="GCP (Console)">
|
|
|
|
* **project**: The ID of your GCP project, e.g., `constellation-129857`.
|
|
|
|
You can find it on the [welcome screen of your GCP project](https://console.cloud.google.com/welcome). For more information refer to [Google's documentation](https://support.google.com/googleapi/answer/7014113).
|
|
|
|
* **region**: The GCP region you want to deploy your cluster in, e.g., `us-west1`.
|
|
|
|
You can find a [list of all regions in Google's documentation](https://cloud.google.com/compute/docs/regions-zones#available).
|
|
|
|
* **zone**: The GCP zone you want to deploy your cluster in, e.g., `us-west1-a`.
|
|
|
|
You can find a [list of all zones in Google's documentation](https://cloud.google.com/compute/docs/regions-zones#available).
|
|
|
|
* **serviceAccountKeyPath**: To configure this, you need to create a GCP [service account](https://cloud.google.com/iam/docs/service-accounts) with the following permissions:
|
|
|
|
* `Compute Instance Admin (v1) (roles/compute.instanceAdmin.v1)`
|
|
* `Compute Network Admin (roles/compute.networkAdmin)`
|
|
* `Compute Security Admin (roles/compute.securityAdmin)`
|
|
* `Compute Storage Admin (roles/compute.storageAdmin)`
|
|
* `Service Account User (roles/iam.serviceAccountUser)`
|
|
|
|
Afterward, create and download a new JSON key for this service account. Place the downloaded file in your Constellation workspace, and set the config parameter to the filename, e.g., `constellation-129857-15343dba46cb.json`.
|
|
|
|
* **instanceType**: The VM type you want to use for your Constellation nodes.
|
|
|
|
Supported are all machines from the N2D family with a minimum of 4 vCPUs. It defaults to `n2d-standard-4` (4 vCPUs, 16 GB RAM), but you can use any other VMs from the same family. Refer to [N2D machine series](https://cloud.google.com/compute/docs/general-purpose-machines#n2d_machines) or run `constellation config instance-types` to get the list of all supported options.

|
|
|
|
In case you don't have access to CVMs on Azure, you may use less secure [trusted launch VMs](../workflows/trusted-launch.md) instead. For this, set **confidentialVM** to `false` in the configuration file.
|
|
|
|
:::
|
|
|
|
3. Download the trusted measurements for your configured image.
|
|
|
|
```bash
|
|
constellation config fetch-measurements
|
|
```
|
|
|
|
For details, see the [verification section](../workflows/verify-cluster.md).
|
|
|
|
4. Create the cluster with one control-plane node and two worker nodes. `constellation create` uses options set in `constellation-conf.yaml`.
|
|
|
|
:::tip
|
|
|
|
On Azure, you may need to wait 15+ minutes at this point for role assignments to propagate.
|
|
|
|
:::
|
|
|
|
```bash
|
|
constellation create --control-plane-nodes 1 --worker-nodes 2 -y
|
|
```
|
|
|
|
This should give the following output:
|
|
|
|
```shell-session
|
|
$ constellation create ...
|
|
Your Constellation cluster was created successfully.
|
|
```
|
|
|
|
5. Initialize the cluster
|
|
|
|
```bash
|
|
constellation init
|
|
```
|
|
|
|
This should give the following output:
|
|
|
|
```shell-session
|
|
$ constellation init
|
|
Your Constellation master secret was successfully written to ./constellation-mastersecret.json
|
|
Initializing cluster ...
|
|
Your Constellation cluster was successfully initialized.
|
|
|
|
Constellation cluster identifier g6iMP5wRU1b7mpOz2WEISlIYSfdAhB0oNaOg6XEwKFY=
|
|
Kubernetes configuration constellation-admin.conf
|
|
|
|
You can now connect to your cluster by executing:
|
|
export KUBECONFIG="$PWD/constellation-admin.conf"
|
|
```
|
|
|
|
The cluster's identifier will be different in your output.
|
|
Keep `constellation-mastersecret.json` somewhere safe.
|
|
This will allow you to [recover your cluster](../workflows/recovery.md) in case of a disaster.
|
|
|
|
:::info
|
|
|
|
Depending on your CSP and region, `constellation init` may take 10+ minutes to complete.
|
|
|
|
:::
|
|
|
|
6. Configure kubectl
|
|
|
|
```bash
|
|
export KUBECONFIG="$PWD/constellation-admin.conf"
|
|
```
|
|
|
|
## Deploy a sample application
|
|
|
|
1. Deploy the [emojivoto app](https://github.com/BuoyantIO/emojivoto)
|
|
|
|
```bash
|
|
kubectl apply -k github.com/BuoyantIO/emojivoto/kustomize/deployment
|
|
```
|
|
|
|
2. Expose the frontend service locally
|
|
|
|
```bash
|
|
kubectl wait --for=condition=available --timeout=60s -n emojivoto --all deployments
|
|
kubectl -n emojivoto port-forward svc/web-svc 8080:80 &
|
|
curl http://localhost:8080
|
|
kill %1
|
|
```
|
|
|
|
## Terminate your cluster
|
|
|
|
```bash
|
|
constellation terminate
|
|
```
|
|
|
|
This should give the following output:
|
|
|
|
```shell-session
|
|
$ constellation terminate
|
|
Terminating ...
|
|
Your Constellation cluster was terminated successfully.
|
|
```
|
|
|
|
:::tip
|
|
|
|
On Azure, if you have used the `az` script, you can keep the prerequisite resources and reuse them for a new cluster.
|
|
|
|
Or you can delete them:
|
|
|
|
```bash
|
|
RESOURCE_GROUP=constellation # name of your cluster resource group
|
|
APPID=$(jq -r '.appId' azureServiceAccountKey.json)
|
|
az ad sp delete --id "${APPID}"
|
|
az group delete -g "${RESOURCE_GROUP}-identity" --yes --no-wait
|
|
az group delete -g "${RESOURCE_GROUP}" --yes --no-wait
|
|
```
|
|
