Note of Google Cloud SDK.

Common

Use -q to avoid inactive prompt when delete resources.

gcloud iam service-accounts delete -q ${SERVICE_ACCOUNT_EMAIL}

Impersonate as a service account

gcloud --impersonate-service-account=${SERVICE_ACCOUNT_EMAIL} compute instances list

Use Python3 to fix encoding problem

# Use python3
export CLOUDSDK_PYTHON=python3

# Show Billing Account Name
gcloud alpha billing accounts list --format='value[separator=","](ACCOUNT_ID,NAME)'

Use Python3 to fix Windows Long Path problem

Problem:

There's a file path exceed 260 characters: "F:\path_very_long_and_exceed260char\file.txt".

> gsutil cp -r F:\Data gs://BUCKET_NAME/Data
OSError: The system cannot find the path specificed

Root cause:

Cloud SDK and gsutil default use Python 2.7 and Python 2.7 does not support Windows registry "LongPathsEnabled".

Solution:

1. Install python3.6+
2. Set the environment variable: CLOUDSDK_GSUTIL_PYTHON
3. Run gsutil command in Powershell:

> $Env:CLOUDSDK_GSUTIL_PYTHON="py"
> gsutil cp -r F:\Data gs://BUCKET_NAME/Data

IAM

Show all IAM roles

gcloud iam roles list | grep "name:"

List User Role assignments

gcloud organizations get-iam-policy <ORGANIZATION_ID> \
  --filter="bindings.members:<TEST-USER@GMAIL.COM>" \
  --flatten="bindings[].members" \
  --format="table(bindings.role)" > roles.txt

Reference: https://blog.doit-intl.com/view-gcp-user-role-assignments-2241373529f1

Copy roles to another user

This script adds IAM policy binding from user user1@example.com to user user2@example.com in the project.

SOURCE_USER="user:user1@example.com"
TARGET_USER="user:user2@example.com"
SOURCE_PROJECT_ID=<PROJECT_A_ID>
TARGET_PROJECT_ID=<PROJECT_B_ID>

ROLES=($(gcloud projects get-iam-policy $SOURCE_PROJECT_ID --flatten=bindings --filter="bindings.members=($SOURCE_USER)" --format="value[delimiter=' '](bindings.role)"))
for role in ${ROLES[@]}; do
  role=${role//$SOURCE_PROJECT_ID/$TARGET_PROJECT_ID}
  echo "grant $TARGET_USER with $role"
  gcloud projects add-iam-policy-binding $TARGET_PROJECT_ID \
    -q \
    --member=$TARGET_USER \
    --role=$role \
    > /dev/null
done

Copy custom role to another project

SOURCE_PROJECT_ID=<PROJECT_A_ID>
TARGET_PROJECT_ID=<PROJECT_B_ID>
ROLE_ID=<ROLE_ID> # Remeber remove prefix: projects/<PROJECT_ID>/roles/

gcloud iam roles describe --project=$SOURCE_PROJECT_ID $ROLE_ID > $ROLE_ID.yml

sed -i '/^etag/d' $ROLE_ID.yml
sed -i '/^name/d' $ROLE_ID.yml

gcloud iam roles create $ROLE_ID --project=$TARGET_PROJECT_ID --file=$ROLE_ID.yml

Compute

List compute instances with network tags

gcloud compute instances list \
  --format="table[box](name, tags.items.flatten())" \
  --sort-by="name"

Count by disk types

gcloud compute instances list \
  --filter="status=running" \
  --format="value(machine_type.basename())" \
  | sort \
  | uniq -c

Count by disk size

gcloud compute disks list \
  --format="value(size_gb)" \
  | sort \
  | uniq -c

Delete os-login profile all ssh-keys

myArray=$(gcloud compute os-login ssh-keys list --format='value(key)')

for str in ${myArray[@]}; do
  gcloud compute os-login ssh-keys remove --key=$str
done

BigQuery

Show BigQuery public dataset

bq ls bigquery-public-data:

List bigquery query jobs' totalBytesBilled

Install Dependency in Cloud Shell

sudo apt-get install gawk

Format output and export as csv file

bq ls -j -a --format=prettyjson -n 5000 \
  | jq -r '.[] | .statistics.startTime + "," + .id + "," + .user_email + "," +.statistics.query.totalBytesBilled' \
  | awk -F',' '{ printf "%s, %s, %s, %.2fGB\n", strftime("%Y-%m-%d %H:%M:%S", $1/1000), $2, $3, $4/1024/1024/1024; }' \
  > output.csv

columns:

• startTime, convert time format from timestamp(millisecond) to "%Y-%m-%d %H:%M:%S"
• job_id
• user_email
• totalBytesBilled, convert B to GB

Monitoring

List Cloud Monitoring dashboards

gcloud beta monitoring dashboards list --format="value(name, displayName, etag)"

Network

Show dynamic routes destination ranges of Cloud Router

gcloud compute routers get-status ${CLOUD_ROUTER} \
  --region=${REGION} \
  --format="value(result.bestRoutes.destRange)" \
  | tr ";" "\n" \
  | sort
