This holds scripts for spinning up extra workers for gerrit CI on GCE.

VMs should be created as:

• named city-hackathon-40, city-hackathon-41, etc; the numbers should be free in the CI master

• Machine: 24 CPUs/90G RAM.

• Disk: RHEL 7 hardened image on 100G SSD Persistent Disk

• SSH: add your personal key.

Here is a gcloud command:

gcloud compute instances create \
   --custom-cpu=24 \
   --custom-memory=90 \
   --image-project eip-images \
   --image-family rhel-7-drawfork \
   --boot-disk-size=100GB \
   --boot-disk-type=pd-ssd \
   --zone=us-east4-a \
   city-hackathon-44

Install your own key:

gcloud compute ssh city-hackathon-44 --command='echo KEY >> .ssh/authorized_keys'

Steps:

1. Become root sudo su -

2. yum install -y git

3. Install the private key under .ssh/id_ecdsa, available to gerritcodereview-team members.

4. Download:

   git clone https://gerrit.googlesource.com/gerrit-ci-scripts/
   

5. Run setup.sh (one time)

   sh gerrit-ci-scripts/worker/setup.sh
