Zorluk: OrtaDeploying and Managing Compute Engine Virtual Machines

A DevOps engineer is scripting the deployment of a Compute Engine instance using the `gcloud` CLI. The VM requires a local initialization script `./init.sh` to run at boot time and must run under an existing custom service account `[email protected]`. Which TWO `gcloud compute instances create` flags should be included in the command execution?

  1. --metadata-from-file=startup-script=./init.shCevap
  2. [email protected]Cevap
  3. C
    --startup-script=./init.sh
  4. D
    --iam-role=roles/editor

Cevap

The correct options are `--metadata-from-file=startup-script=./init.sh` and `[email protected]`.
To provision a Compute Engine VM with a custom service account and a local startup script, two distinct `gcloud` flags are required: `--service-account` specifies the custom service account identity, and `--metadata-from-file=startup-script=...` loads the contents of the specified local file into the VM's metadata.

Adım Adım Çözüm

1
Identify the flag required to pass a local startup script file during instance creation.
Determine that local file content must be loaded into instance metadata using `--metadata-from-file=startup-script=./init.sh`.
Compute Engine uses instance metadata to handle startup script execution, and local file contents must be read using the `--metadata-from-file` flag.
2
Identify the flag required to associate a custom service account with the Compute Engine instance.
Determine that `[email protected]` is used to attach the service account.
The `--service-account` flag explicitly assigns identity and associated credentials to the virtual machine instance.
