Destroy a Fabric

Destroying a Fabric is very easy and is two steps:

  1. Terminate the Kubernetes cluster.
  2. Terminate any provisioned infrastructure and the underlying network.

Danger Will Robinson! Danger!

Destroying a fabric cannot be undone! All running systems including data storage will be wiped from existence in that fabric only! You have been warned!

Procedure

Each instructions assumes you're starting from the root directory of the repository:

  1. Teardown the Kubernetes cluster:

    cd kubernetes/
terraform plan -var-file=../config.json -destroy -out plan-destroy.out
terraform apply plan-destroy.out

kops delete cluster \
    --yes \
    --name="$(cd .. && bin/get_fabric_fqdn.py)" \
    --state="s3://$(cd .. && bin/get_state_store_name.py)"

    When all of these commands are completed then the Kubernetes cluster will be either completely shutdown or in a state of shutting down (EC2 instance shutdown is asynchronous). If you only want to teardown the Kubernetes cluster and not the rest of the fabric then DO NOT RUN THE NEXT STEP!

  2. Teardown the infrastructure fabric:

    terraform plan -var-file=../config.json -destroy -out plan-destroy.out
terraform apply plan-destroy.out
