 Bootstrapping
 =============
 
+OS Installation - Switches
+==========================
+
+.. note::
+
+   This part will be done automatically once we have a DHCP and HTTP server set up in the infrastructure.
+   For now, we need to download and install the ONL image manually.
+
+Install ONL with Docker
+-----------------------
+First, enter **ONIE rescue mode**.
+
+Set up IP and route
+^^^^^^^^^^^^^^^^^^^
+.. code-block:: console
+
+   # ip addr add 10.92.1.81/24 dev eth0
+   # ip route add default via 10.92.1.1
+
+- `10.92.1.81/24` should be replaced by the actual IP and subnet of the ONL.
+- `10.92.1.1` should be replaced by the actual default gateway.
+
+Download and install ONL
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. code-block:: console
+
+   # wget https://github.com/opennetworkinglab/OpenNetworkLinux/releases/download/v1.3.2/ONL-onf-ONLPv2_ONL-OS_2020-10-09.1741-f7428f2_AMD64_INSTALLED_INSTALLER
+   # sh ONL-onf-ONLPv2_ONL-OS_2020-10-09.1741-f7428f2_AMD64_INSTALLED_INSTALLER
+
+The switch will reboot automatically once the installer is done.
+
+.. note::
+
+   Alternatively, we can `scp` the ONL installer into ONIE manually.
+
+Setup BMC for remote console access
+-----------------------------------
+Log in to the BMC from ONL by
+
+.. code-block:: console
+
+   # ssh root@192.168.0.1 # pass: 0penBmc
+
+on `usb0` interface.
+
+Once you are in the BMC, run the following commands to setup IP and route (or offer a fixed IP with DHCP)
+
+.. code-block:: console
+
+   # ip addr add 10.92.1.85/24 dev eth0
+   # ip route add default via 10.92.1.1
+
+- `10.92.1.85/24` should be replaced by the actual IP and subnet of the BMC.
+  Note that it should be different from the ONL IP.
+- `10.92.1.1` should be replaced by the actual default gateway.
+
+BMC uses the same ethernet port as ONL management so you should give it an IP address in the same subnet.
+BMC address will preserve during ONL reboot, but won’t be preserved during power outage.
+
+To log in to ONL console from BMC, run
+
+.. code-block:: console
+
+   # /usr/local/bin/sol.sh
+
+If `sol.sh` is unresponsive, please try to restart the mainboard with
+
+.. code-block:: console
+
+   # wedge_power.sh restart
+
+Setup network and host name for ONL
+-----------------------------------
+
+.. code-block:: console
+
+   # hostnamectl set-hostname <host-name>
+
+   # vim.tiny /etc/hosts # update accordingly
+   # cat /etc/hosts # example
+   127.0.0.1 localhost
+   10.92.1.81 menlo-staging-spine-1
+
+   # vim.tiny /etc/network/interfaces.d/ma1 # update accordingly
+   # cat /etc/network/interfaces.d/ma1 # example
+   auto ma1
+   iface ma1 inet static
+   address 10.92.1.81
+   netmask 255.255.255.0
+   gateway 10.92.1.1
+   dns-nameservers 8.8.8.8

+TOST Deployment
+===============
+
+Update aether-pod-config
+========================
+
+Aether-pod-configs is a git project hosted on **gerrit.opencord.org** and we placed the following materials in it.
+
+- Terraform scripts to install TOST applications on Rancher, including ONOS, Stratum and Telegraf.
+- Customized configuration for each application (helm values).
+- Application specific configuration files, including ONOS network configuration and Stratum chassis config.
+
+Here is an example folder structure:
+
+.. code-block:: console
+
+   ╰─$ tree staging/ace-menlo/tost

+   └── variables.tf
+
+There are four Terraform scripts inside **tost** directory and are responsible for managing each service.
+
+Root folder
+^^^^^^^^^^^
+Terraform reads **app_map.tfvars** to know which application will be installed on Rancher
+and which version and customized values need to apply to.
+
+Here is the example of **app_map.tfvars** which is used to install the **hostpath** storage.
+We specify the Helm Chart version to **0.2.9** and use the file **hostpath.yaml** as the custom values
+
+.. code-block::
+
+   project_name     = "tost"
+   namespace_name   = "tost"
+
+   app_map = {
+      hostpath-provisioner = {
+         app_name         = "hostpath-provisioner"
+         target_namespace = "tost"
+         catalog_name     = "rimusz"
+         template_name    = "hostpath-provisioner"
+         template_version = "0.2.9"
+         values_yaml      = ["hostpath.yaml"]
+      }
+   }
+
+The content of **hostpath.yaml** looks like below.
+It follows the standard yaml format and we use this file to customize the **hostpath** Helm Chart.
+
+.. code-block::
+
+   storageClass:
+      name: fast-disks
+
+ONOS folder
+^^^^^^^^^^^
+All files under **onos** directory are related to ONOS application.
+As we mentioned above, the **app_map.tfvars** describe the information about ONOS helm chart.
+
+In this example, we specify the **onos-tost** helm chart version to **0.1.18** and load **onos.yaml**
+as custom value files.
+
+.. code-block::
+
+   apps = ["onos"]
+
+   app_map = {
+      onos = {
+         app_name         = "onos-tost"
+         project_name     = "tost"
+         target_namespace = "onos-tost"
+         catalog_name     = "onos"
+         template_name    = "onos-tost"
+         template_version = "0.1.18"
+         values_yaml      = ["onos.yaml"]
+      }
+   }
+
+**onos.yaml** used to custom your ONOS-tost Helm chart values and please pay attention to the last section, config.
+
+.. code-block:: yaml

+         clusterUrl: http://onos-tost-onos-classic-hs.tost.svc:8181/onos/v1/cluster
+
+Once the **onos-tost** containers are deployed into Kubernetes,
+it will read **onos-netcfg.json** file from the **aether-pod-config** and please change the folder name to different location if necessary.
+
+**onos-netcfg.json** is environment dependent and please change it to fit your environment.
+
+..
+   TODO: Add an example based on the recommended topology
+
+Stratum folder
+^^^^^^^^^^^^^^
+Stratum uses a similar directory structure as ONOS for Terraform and its configuration files.
+
+The customize value file is named **stratum.yaml**
+
+.. code-block::
+
+   app_map = {
+      stratum= {
+         app_name         = "stratum"
+         project_name     = "tost"
+         target_namespace = "stratum"
+         catalog_name     = "stratum"
+         template_name    = "stratum"
+         template_version = "0.1.9"
+         values_yaml      = ["stratum.yaml"]
+      }
+   }
+
+Like ONOS, **stratum.yaml** used to customize Stratum Helm Chart and please pay attention to the config section.
+
+.. code-block:: yaml
+
+   image:
+      registry: registry.aetherproject.org
+      repository: tost/stratum-bfrt
+      tag: 9.2.0-4.14.49
+      pullPolicy: Always
+      pullSecrets:
+         - aether-registry-credential
+
+   extraParams:
+      - "-max_log_size=0"
+      - '-write_req_log_file=""'
+      - '-read_req_log_file=""'
+      - "-v=0"
+      - "-stderrthreshold=0"
+      - "-bf_switchd_background=false"
+
+   nodeSelector:
+   node-role.aetherproject.org: switch
+
+   tolerations:
+      - effect: NoSchedule
+         value: switch
+         key: node-role.aetherproject.org
+
+   config:
+      server: gerrit.opencord.org
+      repo: aether-pod-configs
+      folder: staging/ace-onf-menlo/tost/stratum
+
+Stratum has the same deployment workflow as ONOS.
+Once it is deployed to Kubernetes, it will read switch-dependent config files from the aether-pod-configs repo.
+The key folder indicates that relative path of configs.
+
+.. attention::
+
+   The switch-dependent config file should be named as **${hostname}-chassis-config.pb.txt**.
+   For example, if the host name of your Tofino switch is **my-leaf**, please name config file **my-leaf-config.pb.txt**.
+
+..
+   TODO: Add an example based on the recommended topology
+
+Telegraf folder
+^^^^^^^^^^^^^^^
+
+The app_map.tfvars specify the Helm Chart version and the filename of the custom Helm value file.
+
+.. code-block::
+
+   apps=["telegraf"]
+
+   app_map = {
+      telegraf= {
+         app_name         = "telegraf"
+         project_name     = "tost"
+         target_namespace = "telegraf"
+         catalog_name     = "influxdata"
+         template_name    = "telegraf"
+         template_version = "1.7.23"
+         values_yaml      = ["telegraf.yaml"]
+      }
+   }
+
+The **telegraf.yaml** used to override the Telegraf Helm Chart and its environment-dependent.
+Please pay attention to the **inputs.addresses** section.
+Telegraf will read data from stratum so we need to specify all Tofino switch’s IP addresses here.
+Taking Menlo staging pod as example, there are four switches so we fill out 4 IP addresses.
+
+.. code-block:: yaml
+
+   podAnnotations:
+      field.cattle.io/workloadMetrics: '[{"path":"/metrics","port":9273,"schema":"HTTP"}]'
+
+   config:
+      outputs:
+         - prometheus_client:
+            metric_version: 2
+            listen: ":9273"
+   inputs:
+      - cisco_telemetry_gnmi:
+         addresses:
+            - 10.92.1.81:9339
+            - 10.92.1.82:9339
+            - 10.92.1.83:9339
+            - 10.92.1.84:9339
+         redial: 10s
+      - cisco_telemetry_gnmi.subscription:
+         name: stratum_counters
+         origin: openconfig-interfaces
+         path: /interfaces/interface[name=*]/state/counters
+         sample_interval: 5000ns
+         subscription_mode: sample
+
+Quick recap
+^^^^^^^^^^^
+
+To recap, most of the files in **tost** folder can be copied from existing examples.
+However, there are a few files we need to pay extra attentions to.
+
+- **onos-netcfg.json** in **onos** folder
+- Chassis config in **stratum** folder
+  There should be one chassis config for each switch. The file name needs to be **${hostname}-chassis-config.pb.txt**
+- **telegraf.yaml** in **telegraf** folder need to be updated with all switch IP addresses
+
+Double check these files and make sure they have been updated accordingly.
+
+
+Create a review request
+^^^^^^^^^^^^^^^^^^^^^^^
+We also need to create a gerrit review request, similar to what we have done in the **Aether Run-Time Deployment**.
+Please refer to :doc:`Aether Run-Time Deployment <run_time_deployment>` to create a review request.
+
+
+Create TOST deployment job in Jenkins
+=====================================
+There are three major components in the Jenkins system, the Jenkins pipeline and Jenkins Job Builder and Jenkins Job.
+
+.. note::
+
+   All Jenkins related files are placed in a `temporary repository <https://github.com/hwchiu/stratum-example/tree/master/pipelines>`_ and will move to another repo once the Aether Jenkins is ready.
+
+
+Jenkins pipeline
+^^^^^^^^^^^^^^^^
+Jenkins pipeline runs the Terraform scripts to install desired applications into the specified Kubernetes cluster.
+
+Both ONOS and Stratum will read configuration files (network config, chassis config) from aether-pod-config.
+The default git branch is master.
+For testing purpose, we also provide two parameters to specify the number of reviews and patchset.
+We will explain more in the next section.
+
+.. note::
+
+   Currently, we don’t perform the incremental upgrade for TOST application.
+   Instead, we perform the clean installation.
+   In the pipeline script, Terraform will destroy all existing resources and then create them again.
+
+Jenkins jobs
+^^^^^^^^^^^^
+
+Jenkins job is the task unit in the Jenkins system. A Jenkins job contains the following information:
+
+- Jenkins pipeline
+- Parameters for Jenkins pipeline
+- Build trigger
+- Source code management
+
+We created one Jenkins job for each TOST component, per Aether edge.
+We have four Jenkins jobs (HostPath provisioner, ONOS, Stratum and Telegraf) for each edge as of today.
+
+There are 10+ parameters in Jenkins jobs and they can be divided into two parts, cluster-level and application-level.
+Here is an example of supported parameters.
+
+.. image:: images/jenkins-onos-params.png
+   :width: 480px
+
+Application level
+"""""""""""""""""
+
+- **config_review/config_patchset** tell the pipeline script to read the config for ONOS from a specified
+   gerrit review, instead of the HEAD branch. It’s good for developer to test its change before merge.
+- **onos_user/onos_password**: used to login ONOS controller
+   **onos_password** is a key which will load the real password from Jenkins Credential system.
+- **onos_ns**: the namespace we installed the secret file for ONOS, (will refactor in the future).
+- **git_repo/git_server/git_user/git_password_env**: information of git repository, **git_password_env** is a key for
+   Jenkins Credential system.
+
+Cluster level
+"""""""""""""
+- **gcp_credential**: Google Cloud Platform credential for remote storage, used by Terraform.
+- **terraform_dir**: The root directory of the TOST directory.
+- **rancher_cluster**: target Rancher cluster name.
+- **rancher_api_env**: Rancher credential to access Rancher, used by Terraform.
+- **k8s_conifg**: Kubernetes config to access remote Kubernetes cluster.
+
+.. note::
+
+   Typically, developer only focus on **config_review** and **config_patchset**. The rest of them are managed by OPs.
+
+Jenkins Job Builder (JJB)
+^^^^^^^^^^^^^^^^^^^^^^^^^
+We prefer to apply the IaaC (Infrastructure as a Code) for everything.
+We use the JJB (Jenkins Job Builder) to create new Jenkins Job, including the Jenkins pipeline.
+We need to clone a set of Jenkins jobs when a new edge is deployed.
+
+..
+   TODO: Automate Jenkins job creation with JJB once the Aether Jenkins is set updated
+
+Trigger TOST deployment in Jenkins
+==================================
+Ideally, whenever a change is merged into **aether-pod-config**,
+the Jenkins job should be triggered automatically to (re)deploy TOST.
+This is still being set up at this moment.
+Therefore, we need to manually trigger the deployment by clicking the **Build** button
+of each Jenkins job and provide parameters accordingly.
+
+..
+   TODO: Update this once the gerrit trigger is implemented
+
+
+Troubleshooting
+===============
+
+The deployment process involves the following steps:
+
+1. Jenkins Job
+2. Jenkins Pipeline
+3. Clone Git Repository
+4. Execute Terraform scripts
+5. Rancher start to install applications
+6. Applications be deployed into Kubernetes cluster
+7. ONOS/Stratum will read the configuration (network config, chassis config)
+8. Pod become running
+
+Taking ONOS as an example, here's what you can do to troubleshoot.
+
+You can see the log message of the first 4 steps in Jenkins console.
+If something goes wrong, the status of the Jenkins job will be in red.
+If Jenkins doesn't report any error message, the next step is going to Rancher's portal
+to ensure the Answers is same as the *onos.yaml* in *aether-pod-configs*.
