My journey through Google Cloud

google cloud1 min read

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


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

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 "-----------------------------"

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

List compute instances
