Deploy development RP

Prerequisites

Your development environment is prepared according to the steps outlined in Prepare Your Dev Environment

Installing the extension

Build the development az aro extension:

make az

Verify that the ARO extension path is in your az configuration:

grep -q 'dev_sources' ~/.azure/config || cat >>~/.azure/config <<EOF
[extension]
dev_sources = $PWD/python
EOF

Verify the ARO extension is registered:

az -v
...
Extensions:
aro                                0.4.0 (dev) /path/to/rp/python/az/aro
...
Development extension sources:
    /path/to/rp/python
...

Note: you will be able to update your development az aro extension in the future by simply running git pull.

Prepare your environment

If you don't have access to a shared development environment and secrets, follow prepare a shared RP development environment.
Set SECRET_SA_ACCOUNT_NAME to the name of the storage account containing your shared development environment secrets and save them in secrets:
```
SECRET_SA_ACCOUNT_NAME=rharosecretsdev make secrets
```
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).
- RP_MODE: Set to development to use a development RP running at https://localhost:8443/.

Create your own RP database:

az deployment group create \
  -g "$RESOURCEGROUP" \
  -n "databases-development-$USER" \
  --template-file pkg/deploy/assets/databases-development.json \
  --parameters \
    "databaseAccountName=$DATABASE_ACCOUNT_NAME" \
    "databaseName=$DATABASE_NAME" \
  >/dev/null

Run the RP and create a cluster

Source your environment file.
```
. ./env
```
Run the RP
```
make runlocal-rp
```
To create a cluster, EITHER follow the instructions in Create, access, and manage an Azure Red Hat OpenShift 4.3 Cluster. Note that as long as the RP_MODE environment variable is set to development, the az aro client will connect to your local RP.

OR use the create utility:
```
CLUSTER=<cluster-name> go run ./hack/cluster create
```
Later the cluster can be deleted as follows:
```
CLUSTER=<cluster-name> go run ./hack/cluster delete
```
By default, a public cluster will be created. In order to create a private cluster, set the PRIVATE_CLUSTER environment variable to true prior to creation. Internet access from the cluster can also be restricted by setting the NO_INTERNET environment variable to true.

The following additional RP endpoints are available but not exposed via az aro:

Delete a subscription, cascading deletion to all its clusters:

curl -k -X PUT \
  -H 'Content-Type: application/json' \
  -d '{"state": "Deleted", "properties": {"tenantId": "'"$AZURE_TENANT_ID"'"}}' \
  "https://localhost:8443/subscriptions/$AZURE_SUBSCRIPTION_ID?api-version=2.0"

List operations:

curl -k \
  "https://localhost:8443/providers/Microsoft.RedHatOpenShift/operations?api-version=2020-04-30"

View RP logs in a friendly format:

journalctl _COMM=aro -o json --since "15 min ago" -f | jq -r 'select (.COMPONENT != null and (.COMPONENT | contains("access"))|not) | .MESSAGE'

Make Admin-Action API call(s) to a running local-rp

export CLUSTER=<cluster-name>
export AZURE_SUBSCRIPTION_ID=<subscription-id>
export RESOURCEGROUP=<resource-group-name>
  [OR]
. ./env

Perform AdminUpdate on a dev cluster

curl -X PATCH -k "https://localhost:8443/subscriptions/$AZURE_SUBSCRIPTION_ID/resourceGroups/$RESOURCEGROUP/providers/Microsoft.RedHatOpenShift/openShiftClusters/$CLUSTER?api-version=admin" --header "Content-Type: application/json" -d "{}"

Get Cluster details of a dev cluster

curl -X GET -k "https://localhost:8443/subscriptions/$AZURE_SUBSCRIPTION_ID/resourceGroups/$RESOURCEGROUP/providers/Microsoft.RedHatOpenShift/openShiftClusters/$CLUSTER?api-version=admin" --header "Content-Type: application/json" -d "{}"

Get SerialConsole logs of a VM of dev cluster

VMNAME="aro-cluster-qplnw-master-0"
curl -X GET -k "https://localhost:8443/admin/subscriptions/$AZURE_SUBSCRIPTION_ID/resourceGroups/$RESOURCEGROUP/providers/Microsoft.RedHatOpenShift/openShiftClusters/$CLUSTER/serialconsole?vmName=$VMNAME" --header "Content-Type: application/json" -d "{}"

List Clusters of a local-rp

curl -X GET -k "https://localhost:8443/admin/providers/microsoft.redhatopenshift/openshiftclusters"

List cluster Azure Resources of a dev cluster

curl -X GET -k "https://localhost:8443/admin/subscriptions/$AZURE_SUBSCRIPTION_ID/resourceGroups/$RESOURCEGROUP/providers/Microsoft.RedHatOpenShift/openShiftClusters/$CLUSTER/resources"

Perform Cluster Upgrade on a dev cluster

curl -X POST -k "https://localhost:8443/admin/subscriptions/$AZURE_SUBSCRIPTION_ID/resourceGroups/$RESOURCEGROUP/providers/Microsoft.RedHatOpenShift/openShiftClusters/$CLUSTER/upgrade"

Get container logs from an OpenShift pod in a cluster

NAMESPACE=<namespace-name>
POD=<pod-name>
CONTAINER=<container-name>
curl -X GET -k "https://localhost:8443/admin/subscriptions/$AZURE_SUBSCRIPTION_ID/resourceGroups/$RESOURCEGROUP/providers/Microsoft.RedHatOpenShift/openShiftClusters/$CLUSTER/kubernetespodlogs?podname=$POD&namespace=$NAMESPACE&container=$CONTAINER"

Debugging OpenShift Cluster

SSH to the bootstrap node:

NOTE: If you have a password-based sudo command, you must first authenticate before running sudo in the background

sudo openvpn secrets/vpn-$LOCATION.ovpn &
CLUSTER=cluster hack/ssh-agent.sh bootstrap

Get an admin kubeconfig:

CLUSTER=cluster make admin.kubeconfig
export KUBECONFIG=admin.kubeconfig

"SSH" to a cluster node:

Get the admin kubeconfig and export KUBECONFIG as detailed above.
Run the ssh-agent.sh script. This takes the argument is the name of the NIC attached to the VM you are trying to ssh to.
Given the following nodes these commands would be used to connect to the respective node

$ oc get nodes
NAME                                     STATUS     ROLES    AGE   VERSION
aro-dev-abc123-master-0               Ready      master   47h   v1.19.0+2f3101c
aro-dev-abc123-master-1               Ready      master   47h   v1.19.0+2f3101c
aro-dev-abc123-master-2               Ready      master   47h   v1.19.0+2f3101c
aro-dev-abc123-worker-eastus1-2s5rb   Ready      worker   47h   v1.19.0+2f3101c
aro-dev-abc123-worker-eastus2-php82   Ready      worker   47h   v1.19.0+2f3101c
aro-dev-abc123-worker-eastus3-cbqs2   Ready      worker   47h   v1.19.0+2f3101c


CLUSTER=cluster hack/ssh-agent.sh master0 # master node aro-dev-abc123-master-0
CLUSTER=cluster hack/ssh-agent.sh aro-dev-abc123-worker-eastus1-2s5rb # worker aro-dev-abc123-worker-eastus1-2s5rb
CLUSTER=cluster hack/ssh-agent.sh eastus1 # worker aro-dev-abc123-worker-eastus1-2s5rb
CLUSTER=cluster hack/ssh-agent.sh 2s5rb  # worker aro-dev-abc123-worker-eastus1-2s5rb
CLUSTER=cluster hack/ssh-agent.sh bootstrap # the bootstrap node used to provision cluster

Debugging AKS Cluster

Connect to the VPN:

To access the cluster for oc / kubectl or SSH'ing into the cluster you need to connect to the VPN first.

NOTE: If you have a password-based sudo command, you must first authenticate before running sudo in the background

sudo openvpn secrets/vpn-aks-$LOCATION.ovpn &

Access the cluster via API (oc / kubectl):

make aks.kubeconfig
export KUBECONFIG=aks.kubeconfig

$ oc get nodes
NAME                                 STATUS   ROLES   AGE   VERSION
aks-systempool-99744725-vmss000000   Ready    agent   9h    v1.23.5
aks-systempool-99744725-vmss000001   Ready    agent   9h    v1.23.5
aks-systempool-99744725-vmss000002   Ready    agent   9h    v1.23.5

"SSH" into a cluster node:

Run the ssh-aks.sh script, specifying the cluster name and the node number of the VM you are trying to ssh to.

hack/ssk-aks.sh aro-aks-cluster 0 # The first VM node in 'aro-aks-cluster'
hack/ssk-aks.sh aro-aks-cluster 1 # The second VM node in 'aro-aks-cluster'
hack/ssk-aks.sh aro-aks-cluster 2 # The third VM node in 'aro-aks-cluster'

Access via Azure Portal

Due to the fact that the AKS cluster is private, you need to be connected to the VPN in order to view certain AKS cluster properties, because the UI interrogates k8s via the VPN.

Metrics

To run fake metrics socket:

go run ./hack/monitor
