Server Access
For the meantime when you request access to the Akraino Pods at UNH-IOL we will ask that you send us your public ssh key so we can add it to the root users of those machines.
If you wish to have your own user we can get that setup, but it is much quicker and easier if you just stick with the root user
IPMI Access
Once you have successfully connected to the VPN there is a file located in each machine in /opt called ipmi_info.txt, this file has the username and password for the IPMI interfaces.
IMPORTANT:
Please write down the information or copy the file somewhere safe in case of the machines getting reinstalled and the file will be gone. We are trying to prevent sending emails with passwords in them. If for some reason you did not have this info before it got wiped you can email akraino-lab@iol.unh.edu and we will help you by making a new file in the machines with the IPMI username and password.
You can access an IPMI interface like the example below:
Then enter the username and password provided from the file in /opt and now you can manage the system on your and will even be able to add your own public keys in the event of a reinstall of the machine.
If you have any issues with any of the IPMI interfaces please email akraino-lab@iol.unh.edu and we will assist you in anyway we can.

Usage
This POD is used for connected vehicle blueprint.
Tarsframwork is deployed in Ampere Server 1.
TarsNode is deployed in Ampere Server 2 and Ampere Server 3.
To make the CI/CD work, we set up Jenkins master in Ampere Server 1, Jankins slave Ampere Server 2 and 3.
Beyond that, we create a folder in CI/CD gerrit repo( path: ci/ci-management/jjb/connected-vehicle) and write a YAML file. Let Jenkins control the tars framework via the Yaml file.
In the end, we upload the CI/CD log to Akraino Community. In this way to make sure connected vehicle pass R2 release review.
