Creating a cluster

Create a cluster with a controller (currently max: 1) and optionally workers (all in a single region).

python cli.py create-cluster \
    --region_tag gcp:us-central1-a 
    --controller_instance_type e2-standard-2 \
    --worker_instance_type n1-standard-1 \
    --num_workers 2

Add workers with different instance types or from different regions:

python cli.py add-worker --region_tag aws:us-west-1 --worker_instance_type g4dn.xlarge

Deploying an inference service

Create a deployment with:

kubectl --kubeconfig  ~/.skyatc/skyatc/k3s.yaml apply -f kubernetes/deployment.yml

Create a service with:

kubectl --kubeconfig  ~/.skyatc/skyatc/k3s.yaml apply -f kubernetes/service.yml

Once created, you can send requests with:

curl http://35.209.44.206:30153/generate \                                                                                     ─╯
-d '{
"prompt": "San Francisco is a",
"use_beam_search": true,
"n": 4,
"temperature": 0
}'

Output: 
{"text":["San Francisco is a pretty of for start, but I I is not a great place to work.","San Francisco is a very city to live in. \nI also a place to\n live.","San Francisco is a great place to live., but it's not the best place to live in","San Francisco is a city that. go and work.  I a for everyone.  work."]}%

cd ./cluster
sudo docker build -t sarahwooders/skyatc-autoscaler .
docker push sarahwooders/skyatc-autoscaler:latest
