disk: 50GB

Like:

gcloud compute instances create cks-master --zone=europe-west3-c \
--machine-type=e2-medium \
--image=ubuntu-2404-noble-amd64-v20250530 \
--image-project=ubuntu-os-cloud \
--boot-disk-size=50GB

# see available images:
gcloud compute images list --project=ubuntu-os-cloud --no-standard-images --filter="name~'ubuntu-2404'"

Configure

sudo -i
bash <(curl -s https://raw.githubusercontent.com/killer-sh/cks-course-environment/master/cluster-setup/latest/install_master.sh)

Setup cks-worker

Like:

gcloud compute instances create cks-worker --zone=europe-west3-c \
--machine-type=e2-medium \
--image=ubuntu-2404-noble-amd64-v20250530 \
--image-project=ubuntu-os-cloud \
--boot-disk-size=50GB

# see available images:

# install "gcloud" command

# connect "gcloud" to your GCP
gcloud auth login
gcloud projects list
gcloud config set project YOUR_PROJECT

# connect to instance
gcloud compute instances list
gcloud compute ssh cks-master

Open ports
