Gcp Notes

Auth

get the auth file and then:

export GOOGLE_APPLICATION_CREDENTIALS="/usr/home/user/.gcp/XXX-XXX.json"

echo ${GOOGLE_CREDENTIALS}
echo ${GOOGLE_CLOUD_KEYFILE_JSON}
echo ${GCLOUD_KEYFILE_JSON}

whoami ?

gcloud auth list

could be in any one of these env vars:

also consider legacy ocnfig files ( when you want to be a suer, but you want to give the app a json file in an env var )

${HOME}/.config/gcloud/legacy_credentials/user@domain.com

Storage

Types of storage, how to choose:

https://cloud.google.com/storage-options/

Compute

https://cloud.google.com/sdk/gcloud/reference/compute/instances/create

how do I like project and familiy for well known images for terraform builds?

gcloud compute images list  --standard-images

OS Login

So you want to just ssh into the vm like you do everything else, you don't want to use

gcloud ssh login

or the "in browser" ssh client.

great , you want "OS Login"

lots of steps:

1. for the VM set the enable-oslogin meta data value to "TRUE"

in tf like this:

  metadata  = {
    enable-oslogin = "TRUE"
  }

2. give the user the correct roles:

Computer OS Login ( for vanilla , non-root access )
Compute OS Admin login ( for root access via sudo )

via command line this I think:

gcloud projects add-iam-policy-binding project-ID --member \
 serviceAccount:"velos-manager@project-ID.iam.gserviceaccount.com" \
 --role "roles/iam.serviceAccountUser"
 --no-user-output-enabled --quiet
