これは現在不可能のようです。https://github.com/kubernetes/kubernetes/blob/37b5726716231c13117c4b05a841e00417b92cda/pkg/cloudprovider/providers/aws/aws.goの API で次のコードを使用します。
func (s *AWSCloud) EnsureLoadBalancer(name, region string, publicIP net.IP, ports []*api.ServicePort, hosts []string, affinity api.ServiceAffinity) (*api.LoadBalancerStatus, error) {
glog.V(2).Infof("EnsureLoadBalancer(%v, %v, %v, %v, %v)", name, region, publicIP, ports, hosts)
.
.
.
// Create a security group for the load balancer
var securityGroupID string
{
sgName := "k8s-elb-" + name
sgDescription := "Security group for Kubernetes ELB " + name
securityGroupID, err = s.ensureSecurityGroup(sgName, sgDescription, vpcId)
if err != nil {
glog.Error("Error creating load balancer security group: ", err)
return nil, err
}
permissions := []*ec2.IpPermission{}
for _, port := range ports {
portInt64 := int64(port.Port)
protocol := strings.ToLower(string(port.Protocol))
sourceIp := "0.0.0.0/0"
permission := &ec2.IpPermission{}
permission.FromPort = &portInt64
permission.ToPort = &portInt64
permission.IpRanges = []*ec2.IpRange{{CidrIp: &sourceIp}}
permission.IpProtocol = &protocol
permissions = append(permissions, permission)
}
_, err = s.ensureSecurityGroupIngress(securityGroupID, permissions)
if err != nil {
return nil, err
}
}
securityGroupIDs := []string{securityGroupID}
.
.
.
}
セキュリティ グループの作成を防止する方法はありません。
