Guide how migrate cluster ${CLUSTER_ID} from GS MC ${OLD_MC} to CAPA MC ${CAPI_MC}

prereq

• create kubeconfig and vaultconfig for the old MC (where GS cluster is located)
  • opsctl create kubeconfig -i ${OLD_MC}
  • opsctl create vaultconfig -i ${OLD_MC}
  • export the variables from the vaultconfig
• create kubeconfig for the new CAPI MC - ${CAPI_MC}
• export AWS credentials for the AWS account where the cluster is located

export AWS_ACCESS_KEY_ID=AKIARHXXXXXXX
export AWS_SECRET_ACCESS_KEY=2hgUZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
export AWS_REGION=eu-west-1

run the commands in the folowing order:

before running be sure to set current kubernetes contex to ${OLD_MC}

./aws-gs-to-capi create cp --context=${CAPI_MC} --cluster-id=${CLUSTER_ID}
./aws-gs-to-capi update dns --context=${CAPI_MC} --cluster-id=${CLUSTER_ID}
#  now you need to remove manifests from old masters (specialy `api server` and `controller manager`), atm this is not automated
./aws-gs-to-capi create np --context=${CAPI_MC} --cluster-id=${CLUSTER_ID}

how clean:

clean CAPA components first(you need MC CAPI kubeconfig) and than delete cluster via GS api

./aws-gs-to-capi delete np --context=${CAPI_MC} --cluster-id=${CLUSTER_ID}
./aws-gs-to-capi delete dns --context=${CAPI_MC} --cluster-id=${CLUSTER_ID}
./aws-gs-to-capi delete cp --context=${CAPI_MC} --cluster-id=${CLUSTER_ID}
gsctl delete cluster ${CLUSTER_ID}
