The instructions to create an ONAP installation using the OOM Rancher/Kubernetes approach are in the ONAP wiki site (be sure to select the Casablanca version of the instructions). Once installed, there are further instructions on deploying ONAP at this wiki page. To install the development image rather than the nexus3 image, open a terminal session with the VM containing the Rancher controller (sb4-rancher). There are instructions on how to create a ssh tunnel to sb4-rancher at this wiki page. Once logged in, we must update parameter parameters in the values.yaml file in the Helm chart for SDNC in the OOM repository, shown here.
...
The simplest way to override the values is to copy the entire values.yaml file into a separate file (I use ~/oof-pci/override-sndc.yaml) and modify the relevant parameters in that new file. The new values are shown below. We identify the repository with the source image name and tag, create a cluster of three ODL members, and create a redundant MySQL deployment of two instances.

By default, the OOM Rancher/Kubernetes script installs all of the components, which we do not need for the proof-of-concept. We identify which components to install by copying the ~/git/oom/kubernetes/onap/values.yaml file into a separate "override" file (~/oof-pci/override-onap.yaml) and changing "enabled: true" to "enabled: false" for the unneeded components. Currently, these are the selected components.

Command to install ONAP with the development image
Following the guidelines at the OOM wiki page, I use this command to install ONAP with the desired configuration.
...
The parameter "demo" is used to preface each ONAP component with "demo-" so we have "demo-sdnc," for example. The "./onap" parameter instructs helm to use that directory to guide the deployment. The "–namespace --namespace onap" parameter causes ONAP to be deployed into the kubernetes namespace "onap." The "-f ~/oof-pci/override-onap.yaml -f ~/oof-pci/override-sdnc.yaml" parameters instruct helm to override the parameters in the ~/git/oom/kubernetes/onap/values.yaml and ~/git/oom/kubernetes/sdnc/values.yaml file with the values in the files following the "-f" option. There can be a series of override files, and the last file takes precedence.
...
The first command deletes SDNC but, despite the "–purge--purge" option, some residual resources remain. The subsequent commands discovers those resources and generates commands that can be copied and pasted into your terminal session to be executed. If you know how to pipe a string into bash so it can be executed directly, kindly update this codewiki page. The "helm del..." command takes some time, so please be patient. Once SDNC has been deleted, you can install the new version using the commands in the previous section.
