It provides the ability to demonstrate the Istio sandbox +including a service mesh and surrounding tools including tracing, monitoring, and logging. + +The SDC sample comprises the following services: + + * **Proxy** - used to mirror traffic to security (snort-ids) services and propagate traffic to + load balancing services. In future releases, the proxy will process security alerts and + provide access control by blacklisting clients based on source IP address. + + * **Load Balancer** - provides basic round-robin load balancing to other downstream + services without Istio provisions. Istio features built-in load balancing to provide + request routing for canary and A/B scenarios. The sample application employs both tiers + of load balancing to demonstrate how load balancing algorithms can be controlled to + address both network and application requirements. + + * **Intrusion Detection System** - used to detect web vulnerabilities using limited set of + rules/signatures and send security alerts to the proxy. + + * **Server** - simple web servers used to terminate web requests from the load balancing + services for end-to-end traffic flow. + +The table below shows key details of the sample application Kubernetes manifest for the services +outlined above: + ++---------------------+----------------------+------------------------+-----------------------+ +| Service | Kubernetes | Docker Image | Ports | +| | Deployment App Name | | | ++=====================+======================+========================+=======================+ +| Proxy | proxy-access-control | clover-ns-nginx-proxy | HTTP: 9180 | +| | | | GRPC: 50054 | ++---------------------+----------------------+------------------------+-----------------------+ +| Load Balancers | app: http-lb | clover-ns-nginx-lb | HTTP: 9180 | +| | version: http-lb-v1 | | GRPC: 50054 | +| | version: http-lb-v2 | | | ++---------------------+----------------------+------------------------+-----------------------+ +| Intrusion Detection | snort-ids | clover-ns-snort-ids | HTTP: 80, Redis: 6379 | +| System (IDS) | | | GRPC: 50052 (config) | +| | | | GRPC: 50054 (alerts) | ++---------------------+----------------------+------------------------+-----------------------+ +| Servers | clover-server1 | clover-ns-nginx-server | HTTP: 9180 | +| | clover-server2 | | GRPC: 50054 | +| | clover-server3 | | | +| | clover-server4 | | | +| | clover-server5 | | | ++---------------------+----------------------+------------------------+-----------------------+ + +Additionally, the sample uses other ancillary elements including: + + * A Redis in-memory data store for the snort IDS service to write alerts. It can also be used + by the Clover tracing module to analyze traces over time. Standard community containers of + Redis are employed by Clover. + + * A Kubernetes Ingress resource (proxy-gateway) to manage external access to the service mesh. + + * Clover docker container that is used to invoke deployment and cleanup scripts for the sample. + It can also be used to execute scripts that modify run-time service configurations. Using the + container avoids the need to clone the source code. + + * Optional deployment of Jaeger tracing and Prometheus monitoring tools with access to their + browser-based UIs. + +.. image:: imgs/sdc_sample.png + :align: center + :scale: 100% + +The diagram above shows the flow of web traffic where all blue arrows denote the path of incoming +HTTP requests through the service mesh. Requests are directed to the istio-ingress entry point +using the Ingress resource (proxy-gateway). Istio-ingress acts as a gateway and sends traffic to +the proxy-access-control service. Proxy-access-control mirrors traffic to the snort-ids +service for it to monitor all incoming HTTP requests. The snort-ids asynchronously sends alert +notifications to proxy-access-control over GRPC on port 50054, which is denoted in red, and +stores the details of the alert events into Redis for other services to potentially inspect. + +Proxy-access-control also sends traffic to the http-lb load balancing service. Http-lb deploys +two versions (http-lb-v1, http-lb-v2) of itself by sharing the same app name (http-lb) but using +a distinct version in the Kubernetes manifest. By default, without any further configuration, +Istio will load balance requests with a 50/50 percentage split among these two http-lb versions. +Both the load balancers are internally configured by default to send traffic to clover-server1/2/3 +in round-robin fashion. + +A controlling agent that can reside inside or outside of the mesh can be used to modify the +run-time configuration of the services, which is denoted in green. Python sample scripts that +implement a GRPC client act as a control-agent and are used to reconfigure http-lb-v2 to load +balance across clover-server4/5 instead of servers 1/2/3. The sample application provides +additional examples of modifying run-time configurations such as adding user-defined rules +to the snort-ids service to trigger alerts on other network events. + +Deploying the sample app +======================== + +Prerequisites +------------- + +The following assumptions must be met before continuing on to deployment: + + * Ubuntu 16.04 was used heavily for development and is advised for greenfield deployments. + * Installation of Docker has already been performed. It's preferable to install Docker CE. + * Installation of Kubernetes has already been performed. The installation in this guide was + executed in a single-node Kubernetes cluster on a modest virtual machine. + * Installation of a pod network that supports the Container Network Interface (CNI). It is + recommended to use flannel, as most development work employed this network add-on. + * Installation of Istio and Istio client (istioctl) is in your PATH (for deploy from source) + +Deploy with Clover container +---------------------------- + +The easiest way to deploy the sample is to use the Clover container by pulling the +container and executing a top-level deploy script using the following two commands: + +.. code-block:: bash + + $ docker pull opnfv/clover:<release_tag> + +The <release_tag> is **6.0.0** for the Fraser release. However, the latest +will be pulled if the tag is unspecified. + +.. code-block:: bash + + $ sudo docker run --rm \ + -v ~/.kube/config:/root/.kube/config \ + opnfv/clover \ + /bin/bash -c '/home/opnfv/repos/clover/samples/scenarios/deploy.sh' + +The deploy script invoked above begins by installing Istio 0.6.0 into your Kubernetes environment. +It proceeds to deploy the entire SDC manifest. If you've chosen to employ this method of +deployment, you may skip the next section. + +Deploy from source +------------------ + +Ensure Istio 0.6.0 is installed, as a prerequisite, using the following commands: + +.. code-block:: bash + + $ curl -L https://github.com/istio/istio/releases/download/0.6.0/istio-0.6.0-linux.tar.gz | tar xz + $ cd istio-0.6.0 + $ export PATH=$PWD/bin:$PATH + $ kubectl apply -f install/kubernetes/istio.yaml + +The above sequence of commands installs Istio with manual sidecar injection without mutual TLS +authentication between sidecars. + +To continue to deploy from the source code, clone the Clover git repository and navigate +within the samples directory as shown below: + +.. code-block:: bash + + $ git clone https://gerrit.opnfv.org/gerrit/clover + $ cd clover/samples/scenarios + $ git checkout stable/fraser + +To deploy the sample in the default Kubernetes namespace, use the following command for Istio +manual sidecar injection: + +.. code-block:: bash + + $ kubectl apply -f <(istioctl kube-inject --debug -f service_delivery_controller_opnfv.yaml) + +To deploy in another namespace, use the '-n' option. An example namespace of 'sdc' is shown below: + +.. code-block:: bash + + $ kubectl create namespace sdc + $ kubectl apply -n sdc -f <(istioctl kube-inject --debug -f service_delivery_controller_opnfv.yaml) + +When using the above SDC manifest, all required docker images will automatically be pulled +from the OPNFV public Dockerhub registry. An example of using a Docker local registry is also +provided in the ``/clover/samples/scenario`` directory. + +Verifying the deployment +------------------------ + +To verify the entire SDC sample is deployed, ensure the following pods have been deployed +with the command below: + +.. code-block:: bash + + $ kubectl get pod --all-namespaces + +The listing below must include the following SDC pods assuming deployment in the default +Kubernetes namespace: + +.. code-block:: bash + + $ NAMESPACE NAME READY STATUS + default clover-server1-68c4755d9c-7s5q8 2/2 Running + default clover-server2-57d8b786-rf5x7 2/2 Running + default clover-server3-556d5f79cf-hk6rv 2/2 Running + default clover-server4-6d9469b884-8srbk 2/2 Running + default clover-server5-5d64f74bf-l7wqc 2/2 Running + default http-lb-v1-59946c5744-w658d 2/2 Running + default http-lb-v2-5df78b6849-splp9 2/2 Running + default proxy-access-control-6b564b95d9-jg5wm 2/2 Running + default redis 2/2 Running + default snort-ids-5cc97fc6f-zhh5l 2/2 Running + +The result of the Istio deployment must include the following pods: + +.. code-block:: bash + + $ NAMESPACE NAME READY STATUS + istio-system istio-ca-59f6dcb7d9-9frgt 1/1 Running + istio-system istio-ingress-779649ff5b-mcpgr 1/1 Running + istio-system istio-mixer-7f4fd7dff-mjpr8 3/3 Running + istio-system istio-pilot-5f5f76ddc8-cglxs 2/2 Running + +Determining the ingress IP and port +----------------------------------- + +To determine how incoming http traffic on port 80 will be translated, use the following command: + +.. code-block:: bash + + $ kubectl get svc -n istio-system + NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) + istio-ingress LoadBalancer 10.104.208.165 <pending> 80:32410/TCP,443:31045/TCP + +**Note, the CLUSTER-IP of the service will be unused in this example since load balancing service +types are unsupported in this configuration. It is normal for the EXTERNAL-IP to show status +<pending> indefinitely** + +In this example, traffic arriving on port 32410 will flow to istio-ingress. The +istio-ingress service will route traffic to the proxy-access-control service based on a +configured ingress rule, which defines a gateway for external traffic to enter +the Istio service mesh. This makes the traffic management and policy features of Istio available +for edge services. + +Using the sample app +==================== + +To confirm the scenario is running properly, HTTP GET requests can be made from an external +host with a destination of the Kubernetes cluster. Requests can be invoked from the host OS +of the Kubernetes cluster. Modify the port used below (32410) with the port obtained from section +`Determining the ingress IP and port`_. If flannel is being used, requests can use the default +flannel CNI IP address, as shown below: + +.. code-block:: bash + + $ wget http://10.244.0.1:32410/ + $ curl http://10.244.0.1:32410/ + +An HTTP response will be returned as a result of the wget or curl command, if the SDC sample +is operating correctly. However, the visibility into what services were accessed within +the service mesh remains hidden. The next section `Exposing tracing and monitoring`_ shows how +to inspect the internals of the Istio service mesh. + +Exposing tracing and monitoring +------------------------------- + +To gain insight into the service mesh, the Jaeger tracing and Prometheus monitoring tools +can also be deployed. These tools can show how the sample functions in the service mesh. +Using the Clover container, issue the following command to deploy these tools +into your Kubernetes environment: + +.. code-block:: bash + + $ sudo docker run --rm \ + -v ~/.kube/config:/root/.kube/config \ + opnfv/clover \ + /bin/bash -c '/home/opnfv/repos/clover/samples/scenarios/view.sh' + +The Jaeger tracing UI is exposed outside of the Kubernetes cluster via any node IP in the cluster +using the following commands **(above command already executes the two commands below)**: + +.. code-block:: bash + + $ kubectl expose -n istio-system deployment jaeger-deployment --port=16686 --type=NodePort + +Likewise, the Promethues monitoring UI is exposed with the following command: + +.. code-block:: bash + + $ kubectl expose -n istio-system deployment prometheus --port=9090 --type=NodePort + +To find the ports the Jaeger tracing and Prometheus monitoring UIs are exposed on, use the +following command: + +.. code-block:: bash + + $ kubectl get svc --all-namespaces + NAMESPACE NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) + istio-system jaeger-deployment NodePort 10.105.94.85 <none> 16686:32174/TCP + istio-system prometheus NodePort 10.97.74.230 <none> 9090:32708/TCP + +In the example above, the Jaeger tracing web-based UI will be available on port 32171 and +the Prometheus monitoring UI on port 32708. In your browser, navigate to the following +URLs for Jaeger and Prometheus respectively:: + + http://<node IP>:32174 + http://<node IP>:32708 + +Where node IP is an IP from one of the Kubernetes cluster node(s). + +.. image:: imgs/sdc_tracing.png + :align: center + :scale: 100% + +The diagram above shows the Jaeger tracing UI after traces have been fetched for the +proxy-access-control service. After executing an HTTP request using the simple curl/wget +commands outlined in `Using the sample app`_ , a list of SDC services will be displayed +in the top left drop-down box labelled ``Service``. Choose ``proxy-access-control`` in +the drop-down and click the ``Find Traces`` button at the bottom of the left controls. +The blue box denotes what should be displayed for the services that were involved in +handling the request including: + + * istio-ingress + * proxy-access-control + * http-lb + * clover-server1 OR clover-server2 OR clover-server3 + +The individual traces can be clicked on to see the details of the messages between services. + +Modifying the run-time configuration of services +================================================ + +The following control-plane actions can be invoked via GRPC messaging from a controlling agent. +For this example, it is conducted from the host OS of a Kubernetes cluster node. + +**Note, the subsequent instructions assume the flannel network CNI plugin is installed. Other +Kubernetes networking plugins may work but have not been validated.** + +Modifying the http-lb server list +---------------------------------- + +By default, both versions of the load balancers send incoming HTTP requests to clover-server1/2/3 +in round-robin fashion. To have the version 2 load balancer (http-lb-v2) send its traffic to +clover-server4/5 instead, issue the following command: + +.. code-block:: bash + + $ sudo docker run --rm \ + -v ~/.kube/config:/root/.kube/config \ + opnfv/clover \ + /bin/bash -c 'python /home/opnfv/repos/clover/samples/services/nginx/docker/grpc/nginx_client.py \ + --service_type=lbv2 --service_name=http-lb-v2' + +Adding rules to snort-ids +-------------------------- + +The snort service installs the readily available community rules. An initial, basic provision to +allow custom rule additions has been implemented within this release. A custom rule will trigger +alerts and can be defined in order to inspect network traffic. This capability, including +rule manipulation, will be further expounded upon in subsequent releases. For the time being, the +following basic rule additions can be performed using a client sample script. + +A snort IDS alert can be triggered by adding the HTTP User-Agent string shown below. The +signature that invokes this alert is part of the community rules that are installed in the +snort service by default.

"Cloud native" has a ever evolving and expanding definition, -and in Clover, the focus is effectively running and operating VNFs built -in a micro-service design pattern running on Docker containers and -orchestrated by Kubernetes. - -The strength of cloud native applications is their operablity and -scalability. Essential to achieve these qualities is the use of service -mesh. As such, in Fraser release, Clover's emphasis is on demonstrating -running a sample micro-service composed VNF on Istio, the service mesh -platform of Clover's choice in Fraser, and how to maximize visibility -of this sample running in a service mesh. - -What is in Fraser? -================== - - * a sample micro-service composed VNF - - * logging module: fluentd and elasticsearch Kubernetes manifests, - installation validation, log data correlation in datastore - - * tracing module: jaeger Kubernetes manifest, installation validation, - jaegar tracing query tools, trace data correlation in datastore - - * monitoring module: prometheus Kubernetes manifest, installation - validation, prometheous query tools for Istio related metrics, - metrics correlation in datastore - - * Istio route-rules and circuit breaking sample yaml and validation - tools - - * Test scripts - - * Reference for a demo shown during ONS - -Usage -===== - - * each modules (service mesh, logging, tracing, monitoring) are Python - modules with their own set of library calls / API exposed.
