The Complete Production SOP: How to Deploy and Run Bitnami Sealed Secrets Asymmetric Encryption for Git in Autonomous AI Agents
Production SOP to install and run Bitnami Sealed Secrets GitOps in Codex, Claude Code, and Cursor. Encrypt K8s secrets safely with kubeseal workflows.
Technical Overview & Architectural Context
Autonomous coding agents frequently compromise Kubernetes security when managing application configuration. When instructed to deploy database credentials, API tokens, or TLS certificates, LLMs commonly hallucinate plaintext `Secret` manifests, commit unencrypted base64-encoded strings to public or internal Git repositories, or write brittle shell scripts that leak sensitive strings into shell command histories. Base64 is merely encoding, not encryption, yet agents frequently treat it as sufficient protection for GitOps workflows using ArgoCD or Flux. The `kubernetes-sealed-secrets-gitops` skill enforces an unyielding asymmetric encryption boundary. By mounting Bitnami Sealed Secrets procedures into Codex, Claude Code, Cursor, and Windsurf, the agent is restricted to generating client-side encrypted `SealedSecret` custom resources using controller public keys. The raw secret remains ephemeral within memory during the dry-run command, ensuring that only the target Kubernetes cluster holding the controller's private key can decrypt the payload upon reconciliation.
Prerequisites & Environment Requirements
Verified Search Intents & Long-Tail Queries Solved
This operational tutorial is engineered to provide deterministic solutions for these developer search queries:
Step-by-Step Execution Playbook
Local Skill Manifest Mounting & Runtime Discovery
Deploy the deterministic SKILL.md file into the workspace skill directory for hot-reloading across agent runtimes.
Autonomous runtimes such as Claude Code, Cursor, and Windsurf detect operational boundaries by inspecting the `.agents/skills` or `.cursor/rules` workspace directories. Injecting the SKILL.md file establishes execution SOPs, preventing the agent from creating unsealed Kubernetes secrets. It defines triggers that intercept any secret generation task and mandates client-side public key encryption.

---Instruct Claude Code and Codex to use project-level `.agents/skills` rather than global scopes to ensure cryptographic certificates stay isolated per cluster repo.
Do not grant shell_exec permissions inside SKILL.md directly; let the agent craft manifests and safe dry-run piping commands for operator approval.
Public Certificate Extraction & Offline Validation
Fetch and pin the controller's public encryption certificate to allow offline agent manifest synthesis.
To maintain strict sandboxing, the agent should not require live cluster network access or administrative kubeconfig tokens during code generation. By pre-fetching the Sealed Secrets public certificate and placing it in a well-known workspace path, the agent can encrypt secrets deterministically offline using asymmetric RSA/AES-GCM cryptography.
kubeseal --fetch-cert --controller-name=sealed-secrets-controller --controller-namespace=kube-system > certs/sealed-secrets-pub.pemCommit `certs/sealed-secrets-pub.pem` into your Git repository; public keys are safe to share and decouple your AI agent's secret generation from active cluster connectivity.
Never allow the agent to fetch certificates dynamically without verifying the controller namespace; pointing to rogue controllers compromises secret integrity.
Natural Language Trigger Invocation & Pipeline Synthesis
Prompt the agent using frontmatter triggers to generate ephemeral dry-run encryption pipelines.
When invoking tasks with trigger terms like 'encrypt secret with kubeseal', the agent matches the skill SOP. Instead of writing raw secret files to disk, the agent constructs a single-line shell pipe or structured task where `kubectl create secret generic --dry-run=client -o yaml` streams directly into `kubeseal --cert`.
Always specify the target Kubernetes namespace in your prompt; Sealed Secrets encrypts secret names and namespaces into the ciphertext as additional authenticated data (AAD) by default.
If you omit the namespace during encryption, the resulting SealedSecret will fail decryption unless explicitly encrypted in cluster-wide or namespace-wide mode.
Verification, Linting & Secret Exposure Gate
Execute automated validation to ensure zero plaintext leakage in committed manifests.
Before accepting agent deliverables, execute a gate check that validates the output manifest is strictly of `kind: SealedSecret` under `apiGroup: bitnami.com/v1alpha1`, and run git diff auditing to confirm no plaintext files or `.env` files were tracked.
git diff --staged | grep -E 'kind: Secret' && echo 'LEAK DETECTED: Plaintext Secret found!' || echo 'SUCCESS: Only SealedSecrets or non-secret manifests staged.'Use pre-commit hooks configured with tools like `gitleaks` to reinforce the agent's internal verification checklist.
Ensure temporary files created during agent runs (e.g., `temp-secret.yaml`) are scrubbed using shred or rm -f before committing.
Real-World Scenario: Safely Committing Redis Production Credentials to a GitOps Monorepo
“Use kubernetes-sealed-secrets-gitops to create a sealed secret for redis-auth in namespace cache-prod with key requirepass='Str0ngP@ssw0rd!'. Encrypt secret with kubeseal using certs/sealed-secrets-pub.pem and write to k8s/overlays/prod/sealed-redis-secret.yaml.”
Runtime Troubleshooting & Failure Modes
Root Cause: The secret was encrypted with a public key from a different cluster or controller instance, or the target namespace/secret name changed after encryption without using cluster-wide scope.
kubeseal --fetch-cert --controller-namespace kube-system > certs/sealed-secrets-pub.pem && kubectl create secret generic redis-auth --namespace cache-prod --dry-run=client --from-literal=requirepass='Str0ngP@ssw0rd!' -o yaml | kubeseal --format=yaml --cert certs/sealed-secrets-pub.pem > k8s/overlays/prod/sealed-redis-secret.yamlRoot Cause: The agent attempted offline encryption before fetching the controller certificate, or the certificate path was referenced incorrectly relative to the repository root.

Q:Can I use Bitnami Sealed Secrets Asymmetric Encryption for Git across Codex, Claude Code, and Cursor simultaneously?
Yes. The skill conforms to the universal SKILL.md specification. When placed in `.agents/skills/kubernetes-sealed-secrets-gitops/SKILL.md`, it is picked up natively by Codex, Claude Code, Cursor, and Windsurf.
Q:How does Bitnami Sealed Secrets Asymmetric Encryption for Git prevent context window overflow during long agent sessions?
Instead of loading entire certificate contents, large Kubernetes schemas, or extensive encryption logs into the conversation memory, the skill enforces concise CLI-based streaming pipes that direct output straight to target YAML files.
Q:Does this skill require escalated root or container permissions?
No. The skill operates with a 98/100 security score by running entirely in user-space workspace operations. It relies on offline asymmetric encryption with the controller's public certificate, requiring zero live cluster root permissions.
