My journey through Google Cloud

This is my exploration into the unchartered territory of Google Cloud, delving into a multitude of tools and services

CLI commands

# to obtain access credentials for the user account
gcloud auth login

# list all available networks
gcloud compute networks list --project=:project-name

IDS

https://cloud.google.com/intrusion-detection-system/docs/configuring-ids

Query IDS endpoints across projects

gcloud projects list --format="value(projectId)"

for project_id in $(gcloud projects list --format="value(projectId)"); do
  echo "Project: $project_id"
  gcloud ids endpoints list --project=$project_id
done

Query projects that has VPC network but not IDS

# --quiet ignore any interactions

for project_id in $(gcloud projects list --format="value(projectId)"); do
  # Get IDS Endpoints and VPC Networks for the project
  ids_endpoints=$(gcloud ids endpoints list --project=$project_id --quiet --format="value(NAME)")
  vpc_networks=$(gcloud compute networks list --project=$project_id --quiet --format="value(NAME)")

  # Check if the project has VPC Networks but doesn't have IDS endpoints
  if [[ -z "$ids_endpoints" ]] && [[ -n "$vpc_networks" ]]; then
    echo "Project: $project_id"
    echo "VPC Networks:"
    echo "$vpc_networks"
    echo "-----------------------------"
  fi
done

Pulling a docker image from GCR

24 APR 23

I had to delete a image as it’s not used any more and it has security vulnerabilities. Before deleting it, I wanted to back it up just in case. You have to configure credentials to access GCR.

# login
gcloud auth login

# add credentials for GCR repositories
gcloud auth configure-docker

# pull the image
docker pull eu.gcr.io/live/gcf/europe-west2/5f4029542275:latest

List compute instances

gcloud compute instances list --project dev-test
