Deploy development RP

Prerequisites

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

Installing the extension

  1. Build the development az aro extension:

    . ./env
    make az
    
  2. 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. If you need to use the "prod" extension, what is bundled in az natively rather than your ./python, you can unset AZURE_EXTENSION_DEV_SOURCES (found in your ./env file).

Prepare your environment

  1. If you don't have access to a shared development environment and secrets, follow prepare a shared RP development environment.

  2. If you have multiple subscriptions in your account, verify that "ARO SRE Team - InProgress (EA Subscription 2)" is your active subscription:

    az account set --subscription "ARO SRE Team - InProgress (EA Subscription 2)"
    
  3. 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
    
  4. 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/.
  5. 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" \
      1>/dev/null
    

Run the RP and create a cluster

  1. Source your environment file.

    . ./env
    
  2. Run the RP

    make runlocal-rp
    
  3. To create a cluster, EITHER follow the instructions in Create, access, and manage an Azure Red Hat OpenShift 4 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:

    # Create the application to run the cluster as and load it
    CLUSTER=<cluster-name> go run ./hack/cluster createapp
    source clusterapp.env
    # Create the cluster
    CLUSTER=<cluster-name> go run ./hack/cluster create
    

    Later the cluster can be deleted as follows:

    CLUSTER=<cluster-name> go run ./hack/cluster delete
    CLUSTER=<cluster-name> go run ./hack/cluster deleteapp
    

    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.

    NOTE: If the cluster creation fails with unable to connect to Podman socket...dial unix ///run/user/1000/podman/podman.sock: connect: no such file or directory, then you will need enable podman user socket by executing : systemctl --user enable --now podman.socket, and re-run the installation.

  4. 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'
      
    • Optionally, create these aliases for viewing logs

      cat >>~/.bashrc <<'EOF'
      alias rp-logs='journalctl _COMM=aro -o json --since "15 min ago" -f | jq -r '\''select (.COMPONENT != null and (.COMPONENT | contains("access"))|not) | .MESSAGE'\'''
      alias rp-logs-all='journalctl _COMM=aro -o json -e | jq -r '\''select (.COMPONENT != null and (.COMPONENT | contains("access"))|not) | .MESSAGE'\'''
      EOF
      

Use a custom installer

Sometimes you want to use a custom installer, for example, when you want to test a new OCP version's installer. You can create a cluster with the new installer following these steps:

  1. Push the installer image to somewhere accessible from Hive AKS.

    quay.io would be one of the options. You need pull-secret to use the repositories other than arointsvc.azurecr.io. It must be configured in the secrets. If you are using the hack script, you don't have to care about it because the script uses USER_PULL_SECRET automatically.

  2. Run the RP

  3. Update the OpenShift installer version

  4. Create a cluster with the version you updated.

    If you are using the hack script, you can specify the version with OS_CLUSTER_VERSION env var.

Automatically run local RP

If you are already familiar with running the ARO RP locally, you can speed up the process executing the local_dev_env.sh script.

Connect ARO-RP with a Hive development cluster

The env variables names defined in pkg/util/liveconfig/manager.go control the communication of the ARO-RP with Hive.

  • If you want to use ARO-RP + Hive, set HIVE_KUBE_CONFIG_PATH to the path of the kubeconfig of the AKS Dev cluster. Info about creating that kubeconfig (Step Access the cluster via API).
  • If you want to create clusters using the local ARO-RP + Hive instead of doing the standard cluster creation process (which doesn't use Hive), set ARO_INSTALL_VIA_HIVE to true.
  • If you want to enable the Hive adoption feature (which is performed during adminUpdate()), set ARO_ADOPT_BY_HIVE to true.

After setting the above environment variables (using export directly in the terminal or including them in the env file), connect to the VPN (Connect to the VPN section).

Then proceed to run the ARO-RP as usual.

After that, when you create a cluster, you will be using Hive behind the scenes. You can check the created Hive objects following Debugging OpenShift Cluster and using the oc command.

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

    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
