Prepare a shared RP development environment

Follow these steps to build a shared RP development environment and secrets file. A single RP development environment can be shared across multiple developers and/or CI flows. It may include multiple resource groups in multiple locations.

Prerequisites

  1. You will need Contributor and User Access Administrator roles on your Azure subscription, as well as the ability to create and configure AAD applications.

  2. Set the az account

    az account set -n "<your-azure-subscription>"

  3. You will need a resource group for global infrastructure

    GLOBAL_RESOURCEGROUP=global-infra
az group create -n $GLOBAL_RESOURCEGROUP --location eastus

  4. You will need a publicly resolvable DNS Zone resource in your Azure subscription. Set PARENT_DOMAIN_NAME and PARENT_DOMAIN_RESOURCEGROUP to the name and resource group of the DNS Zone resource:

    PARENT_DOMAIN_NAME=<your-dns-parent-domain>
PARENT_DOMAIN_RESOURCEGROUP=global-infra

az network dns zone create --name $PARENT_DOMAIN_NAME -g $PARENT_DOMAIN_RESOURCEGROUP

  5. You will need a storage account in your Azure subscription in which to store shared development environment secrets. The storage account must contain a private container named secrets. All team members must have Storage Blob Data Reader or Storage Blob Data Contributor role on the storage account. Set SECRET_SA_ACCOUNT_NAME to the name of the storage account. Set SECRET_STORAGE_RESOURCEGROUP to the name of the resourcegroup to deploy the storage into.

    export SECRET_SA_ACCOUNT_NAME=<your-storage-account-name>
export SECRET_STORAGE_RESOURCEGROUP=<resource-group-for-secret-storage>
# When sourcing deploy-shared-env.sh environment variables may not be set,
# that is okay for the purpose of just deploying storage.
. ./hack/devtools/deploy-shared-env.sh 

deploy_global_secret_storage

  6. You will need an AAD object (this could be your AAD user, or an AAD group of which you are a member) which will be able to administer certificates in the development environment key vault(s). Set ADMIN_OBJECT_ID to the object ID.

    ADMIN_OBJECT_ID="$(az ad group show -g '<your-az-group>' --query id -o tsv)"

  7. You will need the ARO RP-specific pull secret (ask one of the @azure-red-hat-openshift GitHub team for this):

    PULL_SECRET=...

  8. Install Go 1.21 or later, if you haven't already.

  9. Install the Azure CLI, if you haven't already.

  10. Log in to Azure:

    az login

AZURE_TENANT_ID=$(az account show --query tenantId -o tsv)
AZURE_SUBSCRIPTION_ID=$(az account show --query id -o tsv)

  11. Git clone this repository to your local machine:

    go get -u github.com/Azure/ARO-RP/...
cd ${GOPATH:-$HOME/go}/src/github.com/Azure/ARO-RP

  12. Prepare the secrets directory:

    mkdir -p secrets

AAD applications

  1. Set a prefix variable used for naming apps/sp
# for PR E2E Environment
PREFIX=aro-v4-e2e

  1. Create an AAD application which will fake up the ARM layer:

    This application requires client certificate authentication to be enabled. A suitable key/certificate file can be generated using the following helper utility:

    go run ./hack/genkey -client arm
mv arm.* secrets

    > __NOTE:__: for macos change the -w0 option for base64 to -b0
AZURE_ARM_CLIENT_ID="$(az ad app create \
  --display-name ${PREFIX}-arm-shared \
  --query appId \
  -o tsv)"
az ad app credential reset \
  --id "$AZURE_ARM_CLIENT_ID" \
  --cert "$(base64 -w0 <secrets/arm.crt)" >/dev/null
az ad sp create --id "$AZURE_ARM_CLIENT_ID" >/dev/null

    Later this application will be granted:

    • User Access Administrator on your subscription.

  2. Create an AAD application which will fake up the first party application.

    This application requires client certificate authentication to be enabled. A suitable key/certificate file can be generated using the following helper utility:

    go run ./hack/genkey -client firstparty
mv firstparty.* secrets

    Now create the application:

    > __NOTE:__: for macos change the -w0 option for base64 to -b0
AZURE_FP_CLIENT_ID="$(az ad app create \
  --display-name ${PREFIX}-fp-shared \
  --query appId \
  -o tsv)"
az ad app credential reset \
  --id "$AZURE_FP_CLIENT_ID" \
  --cert "$(base64 -w0 <secrets/firstparty.crt)" >/dev/null
az ad sp create --id "$AZURE_FP_CLIENT_ID" >/dev/null

    Later this application will be granted:

    • ARO v4 FP Subscription on your subscription.
    • DNS Zone Contributor on the DNS zone in RESOURCEGROUP.
    • Network Contributor on RESOURCEGROUP.

  3. Create an AAD application which will fake up the RP identity.

    AZURE_RP_CLIENT_SECRET="$(uuidgen)"
AZURE_RP_CLIENT_ID="$(az ad app create --display-name ${PREFIX}-rp-shared --end-date '2299-12-31T11:59:59+00:00' --key-type Password --key-value "$AZURE_RP_CLIENT_SECRET" --query appId -o tsv)"
az ad sp create --id "$AZURE_RP_CLIENT_ID" >/dev/null

    Later this application will be granted:

    • Reader on RESOURCEGROUP.
    • Secrets / Get on the key vault in RESOURCEGROUP.
    • DocumentDB Account Contributor on the CosmosDB resource in RESOURCEGROUP.

  4. Create an AAD application which will fake up the gateway identity.

    AZURE_GATEWAY_CLIENT_SECRET="$(uuidgen)"
AZURE_GATEWAY_CLIENT_ID="$(az ad app create \
  --display-name ${PREFIX}-gateway-shared \
  --end-date '2299-12-31T11:59:59+00:00' \
  --key-type password \
  --password "$AZURE_GATEWAY_CLIENT_SECRET" \
  --query appId \
  -o tsv)"
az ad sp create --id "$AZURE_GATEWAY_CLIENT_ID" >/dev/null

  5. Create an AAD application which will be used by E2E and tooling.

    AZURE_CLIENT_SECRET="$(uuidgen)"
AZURE_CLIENT_ID="$(az ad app create \
  --display-name ${PREFIX}-tooling-shared \
  --end-date '2299-12-31T11:59:59+00:00' \
  --key-type password \
  --password "$AZURE_CLIENT_SECRET" \
  --query appId \
  -o tsv)"
az ad sp create --id "$AZURE_CLIENT_ID" >/dev/null

    Later this application will be granted:

    • Contributor on your subscription.
    • User Access Administrator on your subscription.

    You must also manually grant this application the Microsoft.Graph/Application.ReadWrite.OwnedBy permission, which requires admin access, in order for AAD applications to be created/deleted on a per-cluster basis.

    • Go into the Azure Portal
    • Go to Azure Active Directory
    • Navigate to the aro-v4-tooling-shared app registration page
    • Click 'API permissions' in the left side pane
    • Click 'Add a permission'.
    • Click 'Microsoft Graph'
    • Select 'Application permissions'
    • Search for 'Application' and select Application.ReadWrite.OwnedBy
    • Click 'Add permissions'
    • This request will need to be approved by a tenant administrator. If you are one, you can click the Grant admin consent for <name> button to the right of the Add a permission button on the app page

  6. Set up the RP role definitions and subscription role assignments in your Azure subscription. The usage of "uuidgen" for fpRoleDefinitionId is simply there to keep from interfering with any linked resources and to create the role net new. This mimics the RBAC that ARM sets up. With at least User Access Administrator permissions on your subscription, do:

    LOCATION=<YOUR-REGION>
az deployment sub create \
  -l $LOCATION \
  --template-file pkg/deploy/assets/rbac-development.json \
  --parameters \
    "armServicePrincipalId=$(az ad sp list --filter "appId eq '$AZURE_ARM_CLIENT_ID'" --query '[].id' -o tsv)" \
    "fpServicePrincipalId=$(az ad sp list --filter "appId eq '$AZURE_FP_CLIENT_ID'" --query '[].id' -o tsv)" \
    "fpRoleDefinitionId"="$(uuidgen)" \
    "devServicePrincipalId=$(az ad sp list --filter "appId eq '$AZURE_CLIENT_ID'" --query '[].id' -o tsv)" \
  >/dev/null

  7. Create an AAD application which will fake up the portal client.

    This application requires client certificate authentication to be enabled. A suitable key/certificate file can be generated using the following helper utility:

    go run ./hack/genkey -client portal-client
mv portal-client.* secrets

    > __NOTE:__: for macos change the -w0 option for base64 to -b0
AZURE_PORTAL_CLIENT_ID="$(az ad app create \
  --display-name ${PREFIX}-portal-shared \
  --query appId \
  -o tsv)"

OBJ_ID="$(az ad app show --id $AZURE_PORTAL_CLIENT_ID --query id -o tsv)"

az rest --method PATCH \
 --uri "https://graph.microsoft.com/v1.0/applications/$OBJ_ID" \
 --headers 'Content-Type=application/json' \
 --body '{"web":{"redirectUris":["https://locahlost:8444/callback"]}}'

az ad app credential reset \
  --id "$AZURE_PORTAL_CLIENT_ID" \
  --cert "$(base64 -w0 <secrets/portal-client.crt)" >/dev/null

Certificates

  1. Create the VPN CA key/certificate. A suitable key/certificate file can be generated using the following helper utility:

    go run ./hack/genkey -ca vpn-ca
mv vpn-ca.* secrets

  2. Create the VPN client key/certificate. A suitable key/certificate file can be generated using the following helper utility:

    go run ./hack/genkey -client -keyFile secrets/vpn-ca.key -certFile secrets/vpn-ca.crt vpn-client
mv vpn-client.* secrets

  3. Create the proxy serving key/certificate. A suitable key/certificate file can be generated using the following helper utility:

    go run ./hack/genkey proxy
mv proxy.* secrets

  4. Create the proxy client key/certificate. A suitable key/certificate file can be generated using the following helper utility:

    go run ./hack/genkey -client proxy-client
mv proxy-client.* secrets

  5. Create the proxy ssh key/certificate. A suitable key/certificate file can be generated using the following helper utility:

    ssh-keygen -f secrets/proxy_id_rsa -N ''

  6. Create an RP serving key/certificate. A suitable key/certificate file can be generated using the following helper utility:

    go run ./hack/genkey localhost
mv localhost.* secrets

  7. Create the dev CA key/certificate. A suitable key/certificate file can be generated using the following helper utility:

    go run ./hack/genkey -ca dev-ca
mv dev-ca.* secrets

  8. Create the dev client key/certificate. A suitable key/certificate file can be generated using the following helper utility:

    go run ./hack/genkey -client -keyFile secrets/dev-ca.key -certFile secrets/dev-ca.crt dev-client
mv dev-client.* secrets

  9. Create the CA key/certificate. A suitable key/certificate file can be generated using the following helper utility:

    go run ./hack/genkey cluster-mdsd
mv cluster-mdsd.* secrets

Certificate Rotation

This section documents the steps taken to rotate certificates in dev and INT subscriptions

  1. Generate new certificates like we did in AAD application and certificate sections above

  2. Import newly generated certificates to keyvault. Note that this does not include firstparty certificates

source hack/devtools/deploy-shared-env.sh
import_certs_secrets

  1. Update the Azure VPN Gateway configuration. To do this, go to Virtual Network Gateways > Point-to-site configuration and the public cert data from vpn-ca.pem. Delete the old expired root certificate

  2. The OpenVPN configuration file needs to be manually updated. To achieve this, edit the vpn-<region>.ovpn file and add the vpn-client certificate and private key

  3. Next, we need to update certificates owned by FP Service Principal. Current configuration in DEV and INT is listed below. You can get the AAD APP ID from the secrets/env file

Variable Certificate Client Subscription Type AAD App Name Key Vault Name
AZURE_FP_CLIENT_ID firstparty DEV aro-v4-fp-shared-dev v4-eastus-dev-svc
AZURE_ARM_CLIENT_ID arm DEV aro-v4-arm-shared-dev v4-eastus-dev-svc
AZURE_PORTAL_CLIENT_ID portal-client DEV aro-v4-portal-shared-dev v4-eastus-dev-svc
AZURE_FP_CLIENT_ID firstparty INT aro-int-sp aro-int-eastus-svc 
# Import firstparty.pem to keyvault v4-eastus-svc
az keyvault certificate import --vault-name <kv_name>  --name rp-firstparty --file firstparty.pem

# Rotate certificates for SPs ARM, FP, and PORTAL (wherever applicable)
az ad app credential reset \
   --id "$AZURE_ARM_CLIENT_ID" \
   --cert "$(base64 -w0 <secrets/arm.crt)" >/dev/null

az ad app credential reset \
   --id "$AZURE_FP_CLIENT_ID" \
   --cert "$(base64 -w0 <secrets/firstparty.crt)" >/dev/null

az ad app credential reset \
   --id "$AZURE_PORTAL_CLIENT_ID" \
   --cert "$(base64 -w0 <secrets/portal-client.crt)" >/dev/null

  1. The RP makes API calls to kubernetes cluster via a proxy VMSS agent. For the agent to get the updated certificates, this vm needs to be deleted & redeployed. Proxy VM is currently deployed by the deploy_env_dev function in deploy-shared-env.sh. It makes use of env-development.json

  2. Run [rharosecretsdev|e2earosecrets|e2earoclassicsecrets] make secrets-update to upload it to your storage account so other people on your team can access it via make secrets

Environment file

  1. Choose the resource group prefix. The resource group location will be The resource group location will be appended to the prefix to make the resource group name. If a v4-prefixed environment exists in the subscription already, use a unique prefix.

    RESOURCEGROUP_PREFIX=<your-rg-prefix>

  2. Choose the proxy domain name label. This final proxy hostname will be of the form vm0.$PROXY_DOMAIN_NAME_LABEL.$LOCATION.cloudapp.azure.com.

    PROXY_DOMAIN_NAME_LABEL=<your-proxy-domain-name-label>

  3. Create the secrets/env file:

    # use a unique prefix for Azure resources when it is set, otherwise use your user's name
cat >secrets/env <<EOF
export AZURE_PREFIX="${AZURE_PREFIX:-$USER}"
export AZURE_TENANT_ID='$AZURE_TENANT_ID'
export AZURE_SUBSCRIPTION_ID='$AZURE_SUBSCRIPTION_ID'
export AZURE_ARM_CLIENT_ID='$AZURE_ARM_CLIENT_ID'
export AZURE_FP_CLIENT_ID='$AZURE_FP_CLIENT_ID'
export AZURE_FP_SERVICE_PRINCIPAL_ID='$(az ad sp list --filter "appId eq '$AZURE_FP_CLIENT_ID'" --query '[].id' -o tsv)'
export AZURE_PORTAL_CLIENT_ID='$AZURE_PORTAL_CLIENT_ID'
export AZURE_PORTAL_ACCESS_GROUP_IDS='$ADMIN_OBJECT_ID'
export AZURE_PORTAL_ELEVATED_GROUP_IDS='$ADMIN_OBJECT_ID'
export AZURE_CLIENT_ID='$AZURE_CLIENT_ID'
export AZURE_SERVICE_PRINCIPAL_ID='$(az ad sp list --filter "appId eq '$AZURE_CLIENT_ID'" --query '[].id' -o tsv)'
export AZURE_CLIENT_SECRET='$AZURE_CLIENT_SECRET'
export AZURE_RP_CLIENT_ID='$AZURE_RP_CLIENT_ID'
export AZURE_RP_CLIENT_SECRET='$AZURE_RP_CLIENT_SECRET'
export AZURE_GATEWAY_CLIENT_ID='$AZURE_GATEWAY_CLIENT_ID'
export AZURE_GATEWAY_SERVICE_PRINCIPAL_ID='$(az ad sp list --filter "appId eq '$AZURE_GATEWAY_CLIENT_ID'" --query '[].id' -o tsv)'
export AZURE_GATEWAY_CLIENT_SECRET='$AZURE_GATEWAY_CLIENT_SECRET'
export RESOURCEGROUP="$RESOURCEGROUP_PREFIX-\$LOCATION"
export PROXY_HOSTNAME="vm0.$PROXY_DOMAIN_NAME_LABEL.\$LOCATION.cloudapp.azure.com"
export DATABASE_NAME="\$AZURE_PREFIX"
export RP_MODE='development'
export PULL_SECRET='$PULL_SECRET'
export SECRET_SA_ACCOUNT_NAME='$SECRET_SA_ACCOUNT_NAME'

export KEYVAULT_PREFIX="\$RESOURCEGROUP"
export ADMIN_OBJECT_ID='$ADMIN_OBJECT_ID'

export DOMAIN_NAME="\$LOCATION.\$PARENT_DOMAIN_NAME"
export AZURE_ENVIRONMENT='AzurePublicCloud'
export OIDC_STORAGE_ACCOUNT_NAME="\${RESOURCEGROUP//-}oic"
EOF

After creating this file, run make secrets-update to upload it to your storage account so other people on your team can access it via make secrets.

Deploy shared RP development environment (once per location)

Look at the helper file to understand each of the bash functions below.

  1. Copy, edit (if necessary) and source your environment file. The required environment variable configuration is documented immediately below:

    cp env.example env
vi env
. ./env
    • LOCATION: Location of the shared RP development environment (default: eastus).

  2. Create AzSecPack managed Identity https://msazure.visualstudio.com/ASMDocs/_wiki/wikis/ASMDocs.wiki/234249/AzSecPack-AutoConfig-UserAssigned-Managed-Identity (required for deploy_env_dev)

  3. Enable EncryptionAtHost for subscription.

    az feature register --namespace Microsoft.Compute --name EncryptionAtHost

  4. Create the resource group and deploy the RP resources:

    . ./hack/devtools/deploy-shared-env.sh
# Create the RG
create_infra_rg
# Deploy the predeployment ARM template
deploy_rp_dev_predeploy
# Deploy the infrastructure resources such as Cosmos, KV, Vnet...
deploy_rp_dev
# Deploy RP MSI for aks/hive
deploy_rp_managed_identity
# Deploy the proxy and VPN
deploy_env_dev
# Deploy AKS resources for Hive
deploy_aks_dev
# Deploy additional infrastructure required for workload identity clusters
deploy_miwi_infra_dev

    If you encounter a "VirtualNetworkGatewayCannotUseStandardPublicIP" error when running the deploy_env_dev command, you have to override two additional parameters. Run this command instead:

    deploy_env_dev_override

    If you encounter a "SkuCannotBeChangedOnUpdate" error when running the deploy_env_dev_override command, delete the -pip resource and re-run.

  5. Get the AKS kubeconfig and upload it to the storage account:

    make aks.kubeconfig
mv aks.kubeconfig secrets/
make secrets-update

  6. Install Hive on the new AKS

  7. Load the keys/certificates into the key vault:

    import_certs_secrets

    NOTE:: in production, three additional keys/certificates (rp-mdm, rp-mdsd, and cluster-mdsd) are also required in the $KEYVAULT_PREFIX-svc key vault. These are client certificates for RP metric and log forwarding (respectively) to Geneva.

    If you need them in development:

    ! DO NOT RUN THIS IN E2E, INT! !

    az keyvault certificate import \
     --vault-name "$KEYVAULT_PREFIX-svc" \
     --name rp-mdm \
     --file secrets/rp-metrics-int.pem
az keyvault certificate import \
     --vault-name "$KEYVAULT_PREFIX-gwy" \
     --name gwy-mdm \
     --file secrets/rp-metrics-int.pem
az keyvault certificate import \
     --vault-name "$KEYVAULT_PREFIX-svc" \
     --name rp-mdsd \
     --file secrets/rp-logging-int.pem
az keyvault certificate import \
     --vault-name "$KEYVAULT_PREFIX-gwy" \
     --name gwy-mdsd \
     --file secrets/rp-logging-int.pem
az keyvault certificate import \
     --vault-name "$KEYVAULT_PREFIX-svc" \
     --name cluster-mdsd \
     --file secrets/cluster-logging-int.pem

    NOTE:: in development, if you don't have valid certs for these, you can just upload localhost.pem as a placeholder for each of these. This will avoid an error stemming from them not existing, but it will result in logging pods crash looping in any clusters you make. Additionally, no gateway resources are created in development so you should not need to execute the cert import statement for the "-gwy" keyvault.

  8. In pre-production (int, e2e) certain certificates are provisioned via keyvault integration. These should be rotated and generated in the keyvault itself:

Vault Name: "$KEYVAULT_PREFIX-svc"
Certificate: rp-firstparty
Development value: secrets/firstparty.pem

Vault Name: "$KEYVAULT_PREFIX-svc"
Certificate: cluster-mdsd
Development value: secrets/cluster-logging-int.pem

NOTE:: in the new tenant OneCert is not available, therefore firstparty and cluster-mdsd are self signed.

   az keyvault certificate import \
      --vault-name "$KEYVAULT_PREFIX-svc" \
      --name rp-firstparty \
      --file secrets/firstparty.pem

   az keyvault certificate import \
      --vault-name "$KEYVAULT_PREFIX-svc" \
      --name cluster-mdsd \
      --file secrets/cluster-mdsd.pem

  1. Create nameserver records in the parent DNS zone:

    update_parent_domain_dns_zone

  2. Store the VPN client configuration:

    vpn_configuration
