In CDK, how do you enable `associatePublicIpAddress` in an AutoScalingGroup that has a `mixedInstancesPolicy`?lg...
I'm using AWS CDK and am trying to enable the associatePublicIpAddress property for an AutoScalingGroup that's using a launch template.
My first attempt was to just set `associatePublicIpAddress: true`, but I get this error (https://github.com/aws/aws-cdk/blob/master/packages/%40aws-cdk/aws-autoscaling/lib/auto-scaling-group.ts#L1526-L1528)
```typescript
// first attempt
new asg.AutoScalingGroup(this, 'ASG', {
associatePublicIpAddress: true, // here
minCapacity: 1,
maxCapacity: 1,
vpc,
vpcSubnets: {
subnetType: SubnetType.PUBLIC,
onePerAz: true,
availabilityZones: [availabilityZone],
},
mixedInstancesPolicy: {
instancesDistribution: {
spotMaxPrice: '1.00',
onDemandPercentageAboveBaseCapacity: 0,
},
launchTemplate: new LaunchTemplate(this, 'LaunchTemplate', {
securityGroup: this._securityGroup,
role,
instanceType
machineImage,
userData: UserData.forLinux(),
}),
launchTemplateOverrides: [
{
instanceType: InstanceType.of(
InstanceClass.T4G,
InstanceSize.NANO
),
},
],
},
keyName,
})
```
```typescript
// I hit this error from the CDK
if (props.associatePublicIpAddress) {
throw new Error('Setting \'associatePublicIpAddress\' must not be set when \'launchTemplate\' or \'mixedInstancesPolicy\' is set');
}
```
My second attempt was to not set `associatePublicIpAddress` and see if it gets set automatically because the AutoScalingGroup is in a public availablity zone with an internet gateway. However, it still doesn't provision a public ip address.
Has anyone been able to create an autoscaling group with a mix instance policy and an associated public ip?lg...
