+
+#### Creating the Settings Files
+
+##### Local Controller Network Configuration Reference
+The user will find the network configuration file named as
+"user_config.sh" in the ICN parent directory.
+
+`user_config.sh`
+``` shell
+#!/bin/bash
+
+#Edge Location Provider Network configuration
+#Net A - Provider Network
+#If provider having specific Gateway and DNS server details in the edge location,
+#supply those values in nodes.json.
+
+#Ironic Metal3 settings for provisioning network
+#Interface to which Ironic provision network to be connected
+#Net B - Provisioning Network
+export IRONIC_INTERFACE="eno2"
+
+#Ironic Metal3 setting for IPMI LAN Network
+#Interface to which Ironic IPMI LAN should bind
+#Net C - IPMI LAN Network
+export IRONIC_IPMI_INTERFACE="eno1"
+```
+
+#### Running
+After configuring the node inventory file and network configuration
+files, please run `make install` from the ICN parent directory as
+shown below:
+
+``` shell
+root@pod11-jump:# git clone "https://gerrit.akraino.org/r/icn"
+Cloning into 'icn'...
+remote: Counting objects: 69, done
+remote: Finding sources: 100% (69/69)
+remote: Total 4248 (delta 13), reused 4221 (delta 13)
+Receiving objects: 100% (4248/4248), 7.74 MiB | 21.84 MiB/s, done.
+Resolving deltas: 100% (1078/1078), done.
+root@pod11-jump:# cd icn/
+root@pod11-jump:# vim Makefile
+root@pod11-jump:# make install
+```
+
+The following steps occurs once the `make install` command is given.
+1. All the software required to run the bootstrap cluster is
+ downloaded and installed.
+2. k8s cluster to maintain the bootstrap cluster and all the servers
+ in the edge location is installed.
+3. Metal3 specific network configuration such as local DHCP server
+ networking for each edge location, Ironic networking for both
+ provisioning network and IPMI LAN network are identified and
+ created.
+4. Metal3 is launched with IPMI configuration as configured in
+ "user_config.sh" and provisions the bare metal servers using IPMI
+ LAN network. For more information refer to the [Debugging
+ Failures](#debugging-failures) section.
+5. Metal3 launch verification runs with a timeout of 60 mins by
+ checking the status of all the servers being provisioned or not.
+ 1. All servers are provisioned in parallel. For example, if your
+ deployment is having 10 servers in the edge location, all the 10
+ servers are provisioned at the same time.
+ 2. Metal3 launch verification takes care of checking all the
+ servers are provisioned, the network interfaces are up and
+ provisioned with a provider network gateway and DNS server.
+ 3. Metal3 launch verification checks the status of all servers
+ given in user_config.sh to make sure all the servers are
+ provisioned. For example, if 8 servers are provisioned and 2
+ servers are not provisioned, launch verification makes sure all
+ servers are provisioned before launch k8s clusters on those
+ servers.
+6. BPA bare metal components are invoked with the MAC address of the
+ servers provisioned by Metal3, BPA bare metal components decide the
+ cluster size and also the number of clusters required in the edge
+ location.
+7. BPA bare metal runs the containerized Kuberenetes Reference
+ Deployment (KUD) as a job for each cluster. KUD installs the k8s
+ cluster on the slice of servers and install ONAP4K8S and all other
+ default plugins such as Multus, OVN, OVN4NFV, NFD, Virtlet and
+ SRIOV.
+8. BPA REST API agent installed in the bootstrap cluster or jump
+ server, and this install rest-api, rook/ceph, MinIO as the cloud
+ storage. This provides a way for user to upload their own software,
+ container images or OS image to jump server.
+
+## Virtual Deployment Guide
+
+### Standard Deployment Overview
+![Figure 2](figure-2.png)*Figure 2: Virtual Deployment Architecture*
+
+Virtual deployment is used for the development environment using
+Vagrant to create VMs with PXE boot. No setting is required from the
+user to deploy the virtual deployment.
+
+### Snapshot Deployment Overview
+No snapshot is implemented in ICN R2.
+
+### Special Requirements for Virtual Deployment
+
+#### Install Jump Server
+Jump server is required to be installed with Ubuntu 18.04. This will
+install all the VMs and install the k8s clusters.
+
+#### Verifying the Setup - VMs
+To verify the virtual deployment, execute the following commands:
+``` shell
+$ vagrant up --no-parallel
+$ vagrant ssh jump
+vagrant@jump:~$ sudo su
+root@jump:/home/vagrant# cd /icn
+root@jump:/icn# make verifier
+```
+`vagrant up --no-parallel` creates three VMs: vm-jump, vm-machine-1,
+and vm-machine-2, each with 16GB RAM and 8 vCPUs. `make verifier`
+installs the ICN BPA operator and the ICN BPA REST API verifier into
+vm-jump, and then installs a k8s cluster on the vm-machine VMs using
+the ICN BPA operator. The BPA operator installs the multi-cluster KUD
+to bring up k8s with all addons and plugins.
+
+# Verifying the Setup
+ICN blueprint checks all the setup in both bare metal and VM
+deployment. Verify script will check that Metal3 provisioned the OS in
+each bare metal servers by checking with a timeout period of 60 sec
+and interval of 30. BPA operator verifier will check whether the KUD
+installation is complete by doing plain curl command to the k8s
+cluster installed in bare metal and VM setup.
+
+**Bare Metal Verifier**: Run the `make bm_verifer`, it will verify the
+bare-metal deployment.
+
+**Verifier**: Run the `make vm_verifier`, it will verify the virtual
+deployment.
+
+# Developer Guide and Troubleshooting
+For development uses the virtual deployment, it take up to 10 mins to
+bring up the virtual BMC VMs with PXE boot. Virtual deployment works
+well for the BPA operator development for Metal3 installation scripts.
+
+## Utilization of Images
+No images provided in this ICN release.
+
+## Post-deployment Configuration
+No post-deployment configuration required in this ICN release.
+
+## Debugging Failures
+* For first time installation enable KVM console in the trial or lab
+ servers using Raritan console or use Intel web BMC console.
+
+ ![Figure 3](figure-3.png)
+* Deprovision state will result in Ironic agent sleeping before next
+ heartbeat - it is not an error. It results in bare metal server
+ without OS and installed with ramdisk.
+* Deprovision in Metal3 is not straight forward - Metal3 follows
+ various stages from provisioned, deprovisioning and ready. ICN
+ blueprint take care navigating the deprovisioning states and
+ removing the BareMetalHost (BMH) custom resouce in case of cleaning.
+* Manual BMH cleaning of BMH or force cleaning of BMH resource result
+ in hang state - use `make bmh_clean` to remove the BMH state.
+* Logs of Ironic, openstack baremetal command to see the state of the
+ server.
+* Logs of baremetal operator gives failure related to images or images
+ md5sum errors.
+* It is not possible to change the state from provision to deprovision
+ or deprovision to provision without completing that state. All the
+ issues are handled in ICN scripts.
+* k8s cluster failure can be debugged by KUD Pod logs.
+
+## Reporting a Bug
+Required Linux Foundation ID to launch bug in ICN:
+https://jira.akraino.org/projects/ICN/issues
+
+# Uninstall Guide
+
+## Bare Metal deployment
+The command `make clean_all` uninstalls all the components installed by
+`make install`
+* It de-provision all the servers provisioned and removes them from
+ Ironic database.
+* Baremetal operator is deleted followed by Ironic database and
+ container.
+* Network configuration such internal DHCP server, provisioning
+ interfaces and IPMI LAN interfaces are deleted.
+* docker images built during the `make install` are deleted, such as
+ all Ironic, baremetal operator, BPA operator and KUD images.
+* KUD will reset the bootstrap cluster - k8s cluster is torn down in
+ the jump server and all the associated docker images are removed.
+* All software packages installed by `make install_all` are removed,
+ such as Ironic, openstack utility tool, docker packages and basic
+ prerequisite packages.
+
+## Virtual deployment
+The command `make vm_clean_all` uninstalls all the components for the
+virtual deployments.

+# Frequently Asked Questions
+**How to setup IPMI?**
+
+First, make sure the IPMI tool is installed in your servers, if not
+install them using `apt install ipmitool`. Then, check for the
+ipmitool information of each servers using the command `ipmitool lan
+print 1`. If the above command doesn't show the IPMI information, then
+setup the IPMI static IP address using the following instructions:
+- Mostl easy way to set up IPMI topology in your lab setup is by
+ using IPMI tool.
+- Using IPMI tool -
+ https://www.thomas-krenn.com/en/wiki/Configuring_IPMI_under_Linux_using_ipmitool
+- IPMI information can be considered during the BIOS setting as well.
+
+**BMC web console URL is not working?**
+
+It is hard to find issues or reason. Check the ipmitool bmc info to
+find the issues, if the URL is not available.
+
+**No change in BMH state - provisioning state is for more than 40min?**
+
+Generally, Metal3 provision for bare metal takes 20 - 30 mins. Look at
+the Ironic logs and baremetal operator to look at the state of
+servers. Openstack baremetal node shows all state of the server right
+from power, storage.
+
+**Why provider network (baremetal network configuration) is required?**
+
+Generally, provider network DHCP servers in a lab provide the router
+and DNS server details. In some labs, there is no DHCP server or the
+DHCP server does not provide this information.
