k8s-deviceFarmer

Manifests to deploy most recent stable release of openstf in k8s. The manifests evolve the helm chart from agoda to the current k8s APIs.

Quickstart

Install the chart:

helm install my-farm ./manifests/openstf/

This command will create an instance of the chart running in the cluster with the name my-farm. To delete the instance from your cluster:

helm delete my-farm 

Step by step deployment

• Step 1) Install helm

• Step 2) Deploy your cluster of choice (in this case a single node k8s cluster):

deploy_snc

The command deploys a K0s cluster on the local machine. Note that this script requires root privileges.

• Step 3 option a) Deploy pre-requirements such as rethinkdb and all the deviceFarmer apps in a helm chart:

deploy_farm

The above command also uses flannel SDN and metallb to get external access to openstf services. (Root privileges required.)

• Step 3 option b) Assume adb-provider runs using podman in a node outside the k8s cluster. In the node mounting the phone by usb run:

podman play kube usb-phone.yaml

• cont Step 3 option b) Deploy pre-requirements and deviceFarmer deployment except the apps needed to mount the phone:

deploy_farm_local_usb

The above command also uses flannel SDN and metallb to get external access to openstf services. (Root privileges required.)

• Step 4) check that openstf pods and rethinkdb requirements are on a running state:

• Step 5) Plug phone via USB to the k8s node mounting the USB. Start piloting your remote phone fleet:

• Destroy the apps and the cluster:

destroy_farmer

Chart description

Packaging the Chart

For distribution purposes at scale it could be useful to package the helm chart into a single archive file. The helm chart can be packaged by runnning:

helm package openstf

In this case openstf is the path to the location where the chart source is located. The above command will place the archive openstf-release.tgz in the directoy you were when you ran the command.

All-in-one deviceFarmer in RHEL8

• Install podman-compose. Not that RHEL8 requires Extra Packages for Linux (EPEL 8) to get podman-compose built properly.

• To run device-farmer using podman, set the environment variables in the docker-compose-all.yml

  • TZ
  • RETHINKDB_PORT_28015_TCP
  • STF_ADMIN_EMAIL
  • STF_ADMIN_NAME

• Run podman-compose as root to mount the usb:

cd manifests/openstf/stf-local/
echo IP=<YOUR_PUBLIC_IP_ADDRESS> >> .env
podman-compose -f docker-compose-all.yml up -d
