Safe Sre Investigator

Safe SRE Investigator

This skill helps set up and use dedicated read-only Service Accounts for investigating GCP and Kubernetes resources. It provides wrapper scripts safe_gcloud and safe_kubectl to ensure commands are run with these limited-privilege accounts. When suggesting commands, it includes a risk assessment.

Core Tasks

1. Setup GCP: Initialize the GCP service account and safe_gcloud script.
2. Setup Kubernetes: Initialize the Kubernetes service account and safe_kubectl script for a specific cluster.
3. Suggest Commands: Provide gcloud or kubectl commands with risk assessments.

1. Setup GCP (safe_gcloud)

When first using this skill for a project, or if the user asks for setup, guide them through the one-time setup process for GCP access.

Action: Ask the user for the Project ID.

Script: Run the setup script:

bash ./scripts/setup_safe_sre_investigator.sh PROJECT_ID

• This script is idempotent.
• It creates ~/bin/safe_gcloud.
• The user might need to re-source their shell profile.
• IAM roles are in references/iam_roles.md.

2. Setup Kubernetes (safe_kubectl)

This setup must be run for EACH Kubernetes cluster you want to investigate.

Action: Ask the user for the Cluster Name and Cluster Location (Zone or Region).

Script: Run the setup script:

bash ./scripts/setup_safe_kubectl.sh CLUSTER_NAME CLUSTER_LOCATION

• This script needs to be run with user credentials that have permissions to create ServiceAccounts and ClusterRoleBindings in the target cluster.
• It creates a read-only ServiceAccount in the cluster and generates a dedicated kubeconfig in ~/.kube/safe-investigator-configs/.
• It also creates ~/bin/safe_kubectl.
• The K8s roles are in references/k8s_readonly_role.yaml.

3. Suggesting Commands

When the user asks for a command:

• GCP: Use safe_gcloud PROJECT_ID <gcloud commands>.
• Kubernetes: Use safe_kubectl CLUSTER_NAME -- <kubectl commands>.
• Risk Assessment: ALWAYS include a risk assessment block. See references/risk_assessment.md.
• Write Operations: For commands requiring write access, provide the standard gcloud or kubectl command and warn the user to run it with their own credentials, noting the risks.

Example safe_gcloud:

# 🎬 Check GKE cluster status
# ⚠️ Risk: ⚪ NONE: This is a read-only operation.
safe_gcloud my-project container clusters list

Example safe_kubectl:

# 🎬 List pods in the default namespace
# ⚠️ Risk: ⚪ NONE: This is a read-only operation.
safe_kubectl my-cluster -- get pods -n default
