DS=calico-node

CMPATH=/spec/template/spec/containers/0/env/$IDX/value
VAL="cidr=192.168.10.66/24"

kubectl patch ds/$DS -n kube-system --type='json' -p '[
  {"op":"replace","path":"'"$CMPATH"'","value": "'"$VAL"'"},
]'

Add

NM=IP_AUTODETECTION_METHOD
CMPATH=/spec/template/spec/containers/0/env/-
kubectl patch ds/$DS -n kube-system --type='json' -p '[
  {"op":"add","path":"'"$CMPATH"'","value": {"name": "'"$NM"'", "value": "'"$VAL"'"}},
]'

Change apiserver listen address after deployment

CLUSTER_PNET=192.168.10.66/24
 
IDX=`kubectl get pods -n kube-system kube-apiserver-controller -o json | \
  jq '.spec.containers[0].command |map(contains("--advertise-address=")) |index(true)'`
 
CMPATH=/spec/containers/0/command/$IDX
VAL="--advertise-address=1${CLUSTER_PNET%/*}"
DS=kube-apiserver-controller
 
kubectl patch pod/$DS -n kube-system --type='json' -p '[
  {"op":"replace","path":"'"$CMPATH"'","value": "'"$VAL"'"},
]'

had better change the ip before development

# CLUSTER_PNET IP 192.168.10.66 is the apiserver IP
CLUSTER_PNET=192.168.10.66/24
