Deploy remote LKFT lab.

LKFT remote lab

The LKFT framework is a collection of software tools and hardware devices. LKFT is composed of a builds scheduler (Jenkins), a device management framework (LAVA), an LKFT LAVA hardware micro-instance, and a scheduling framework and reporting framework (SQUAD).

This project documents the steps required to deploy a such LKFT test lab. It is named as lkft-remote-lab as it is able to share the following components that Linaro maintaining.

• Jenkins: https://ci.linaro.org/
• LKFT lava-master: https://lkft.validation.linaro.org/
• Scheduling and reporting framework: https://qa-reports.linaro.org/

A lkft-remote-lab could be either of the following types:

• Partially Hosted: only hosts a local lava-slave
• Fully Hosted: hosts lava-slave plus lava-master with a public domain
• Ultra secure: hosts everything except squad

The documents and configs included in the project is trying to cover all the aspects required to deploy a LKFT remote lab with step by step guidelines.

Ultra secure

1. deploy-distributed-lava-instance
2. deploy-docker-based-jenkins
3. setup-report-system

Fully hosted

1. deploy-distributed-lava-instance
2. setup-report-system

Partially hosted

1. Refer to deploy-distributed-lava-instance to install lava-slave.
2. setup-report-system

Once local lava-slave installed and test devices connected, talk to administrator of Linaro's LKFT lava-master to:

1. Establish openvpn connection to the lab
2. Add your local lava-slave as a worker
3. Add your test devices

CI flow

Once LKFT remote lab set properly, a new commit will trigger a new build from Jekkins, the build job will submit test jobs via squad to lava-master, and test results will be pull back and presented instantly. Once all test jobs finished, squad will send a report with the comparison with last build.

Refer to the below diagram for ultra secure mode for the flow

How a micro local LAVA worker looks like

Components used:

• Thinkpad T440 running Debian9.3 as lava-slave
• Raspberry Pi3 plus relay module for power/OTG on/off/reboot control. Refer to power-control.md
• ORICO USB3.0 Hub with Gigabit Ethernet Converter for:
  • Connection to HiKey's serial and OTG USB ports
  • Connection to Raspberry Pi3's Ethernet port to control reply module over ssh
• Test device: HiKey
