Kops create cluster

kops create cluster ¶

Create a Kubernetes cluster.

Synopsis ¶

Create a kubernetes cluster using command line flags. This command creates cloud based resources such as networks and virtual machines. Once the infrastructure is in place Kubernetes is installed on the virtual machines.

These operations are done in parallel and rely on eventual consistency.

kops create cluster [flags]

Examples ¶

  # Create a cluster in AWS in a single zone.
  kops create cluster --name=kubernetes-cluster.example.com \
  --state=s3://kops-state-1234 \
  --zones=eu-west-1a \
  --node-count=2

  # Create a cluster in AWS with HA masters. This cluster
  # has also been configured for private networking in a kops-managed VPC.
  # The bastion flag is set to create an entrypoint for admins to SSH.
  export NODE_SIZE=${NODE_SIZE:-m4.large}
  export MASTER_SIZE=${MASTER_SIZE:-m4.large}
  export ZONES=${ZONES:-"us-east-1d,us-east-1b,us-east-1c"}
  export KOPS_STATE_STORE="s3://my-state-store"
  kops create cluster k8s-clusters.example.com \
  --node-count 3 \
  --zones $ZONES \
  --node-size $NODE_SIZE \
  --master-size $MASTER_SIZE \
  --master-zones $ZONES \
  --networking weave \
  --topology private \
  --bastion="true" \
  --yes

  # Create a cluster in GCE.
  export KOPS_STATE_STORE="gs://mybucket-kops"
  export ZONES=${MASTER_ZONES:-"us-east1-b,us-east1-c,us-east1-d"}
  export KOPS_FEATURE_FLAGS=AlphaAllowGCE # Note: GCE support is not GA.
  kops create cluster kubernetes-k8s-gce.example.com \
  --zones $ZONES \
  --master-zones $ZONES \
  --node-count 3 \
  --yes

  # Generate a cluster spec to apply later.
  # Run the following, then: kops create -f filename.yamlh
  kops create cluster --name=kubernetes-cluster.example.com \
  --state=s3://kops-state-1234 \
  --zones=eu-west-1a \
  --node-count=2 \
  --dry-run \
  -oyaml > filename.yaml
