GCE INSTANCE WAS NOT AUTO RESTARTED AFTER A SHUTDOWN

[Dhandapani Sattanathan]

Our GCE instance was shutdown.After the operation Insatance terminated by Compute Engine.

WHAT IS THE REASON GCE INSTANCE WAS NOT RESTARTED AFTER A SHUTDOWN?

Plz refer the belo image.

After restart manully.GCE instance IP changed.We need static ip.How to set the Static ip?

Plz help!

Using the Developers Console, go to your project, then Compute-> Compute Engine-> VM instances, click on your VM instance and under 'Availability policies' make sure you VM instance is not a preemptible instance. Compute Engine might terminate (preempt) the instance if it requires access to those resources for other tasks. For more information on preemptible instances visit the article [1].

If your VM machine is not a preemptible instance, check the value for 'Automatic restart' option, if it is 'Off' change it to 'On' and for 'On host maintenance' option if the value is 'Terminate VM instance' change it to the 'Migrate VM instance' which are recommended values.

You can also check the availability policies (scheduling) options of your VM instance using the following gcloud command [1]:

$ gcloud compute instances describe INSTANCE_NAME --zone ZONE

Look at the output of the command for the scheduling options:

scheduling:

  automaticRestart: true

  onHostMaintenance: MIGRATE

  preemptible: false

If the scheduling options values of your VM machine are different than the values specified above, use the following gcloud command [2] to modify them to the recommended values:

$ gcloud compute instances set-scheduling INSTANCE_NAME --maintenance-policy MIGRATE --restart-on-failure --zone ZONE

Regarding your question about static IP address, you can promote the ephemeral external IP address which is now being used by your VM machine to a static external IP address using this command [4]:

$ gcloud compute addresses create example-address-1 --addresses 162.222.181.197 --region us-central1

Otherwise, in Developers Console click on your VM instance, Edit the 'External IP'  and change its value to 'New static IP address' which this will assign a new IP address to your VM instance.

Thanks kamran

Is static ip free / Billed?

[Kamran (Google Cloud Support)]

The static IP address if assigned but unused will cost $0.01 per hour. However there will be no charge for static IP address which is assigned and in use. Please visit article [1] for IP address pricing.
