Q

What are gcloud CLI properties?

A

The gcloud CLI properties are settings that affect the behavior of the gcloud CLI tools. Some of these properties can be set by either global or command options—in which case, the value set by the option takes precedence.

Q

What is the gcloud default configuration?

A

When you start using the gcloud CLI, you’ll work with a single configuration named default and you can set properties by running gcloud init or gcloud config set. This single default configuration is suitable for most use cases.

Q

How can you work with multiple projects or authorization accounts?

A

You can set up multiple configurations with gcloud config configurations create and switch among the configurations. Within a configuration, you can customize properties. For example, to set your project within an active configuration use the project property:

gcloud config set project <project-id></project-id>

Q

How can you control prompting?

A

To protect against unintended destructive actions, the gcloud CLI confirms your intentions before executing commands such as gcloud projects delete.

You might be prompted when additional information is needed. For example you will be asked to choose a zone when you create a Compute Engine virtual machine instance using gcloud compute instances create test-instance.

To disable prompting, use the –quiet option.

Q

What is a gcloud CLI Component?

A

Components are the installable parts of the Google Cloud CLI. A component can be a command-line tool (gcloud, bq, and gsutil), a set of gcloud CLI commands at the Alpha or Beta release levels, or a package that contains dependencies used by a tool in the gcloud CLI.

28
Create a compute instance with a specific machine type, n1-standard-2
gcloud compute instances create i1 --machine-type=n1-standard-2 👉 Machine types 👈 Default machine type is n1-standard-1 (1 CPU, 3.75 GB RAM) Instance name argument can be repeated to create multiple instances
29
Create a compute instance in a specific VPC network and subnet
gcloud compute instances create i1 \ --network my-vpc \ --subnet my-subnet-1 Default VPC network is default If --network is set to a VPC network with “custom” subnet mode, then --subnet must also be specified Instance name argument can be repeated to create multiple instances

This allows incoming ICMP and SSH (TCP port 22) traffic to any instances in the VPC network from any source (e.g. from the public Internet). After creating this firewall rule, you’re able to: Ping instances in the VPC network: ping EXTERNAL_IP SSH to instances in the VPC network: gcloud compute ssh i1

105
change the machine type of an instance?
gcloud compute instances set-machine-type INSTANCE_NAME [--machine-type=MACHINE_TYPE] [--zone=ZONE] [--custom-cpu=CUSTOM_CPU --custom-memory=CUSTOM_MEMORY : --custom-extensions --custom-vm-type=CUSTOM_VM_TYPE] [GCLOUD_WIDE_FLAG …] DESCRIPTION gcloud compute instances set-machine-type lets you change the machine type of a virtual machine in the TERMINATED state (that is, a virtual machine instance that has been stopped). For example, the following command would create an instance running an N1 machine type with 4 vCPUs and 5 GB of total memory: gcloud compute instances create example-instance \ --custom-cpu=4 --custom-memory=5 For N2 machine types, use the gcloud compute instances create command and include one of the following options: The --custom-cpu, --custom-memory, and --custom-vm-type flags. The --machine-type=n2-custom-NUMBER_OF_CPUS-NUMBER_OF_MB flag. When using the --custom-memory flag, specify the total amount of memory in GB or in MB. The property must be an integer, so if you want to specify increments of 0.25 GB for memory, convert that value to MB instead. To specify an incremental value, such as 2.5 GB of memory, convert the value to MB and supply the value followed by the MB suffix. The following example creates an instance running an N2 machine type: gcloud compute instances create example-instance \ --custom-cpu=6 --custom-memory=3072MB --custom-vm-type=n2 Alternatively, you can specify a custom machine type using the following format: gcloud compute instances create example-instance \ --machine-type n2-custom-NUMBER_OF_CPUS-NUMBER_OF_MB Replace the following: NUMBER_OF_CPUS: The number of CPUs you want. NUMBER_OF_MB: The amount of memory, in MB. For example: gcloud compute instances create example-instance --machine-type=n2-custom-6-3072
