SPIRE ESSENTIALS: ZERO TRUST IDENTITY FOR MICROSERVICES: Implement workload authentication, mTLS, and automated certificate rotation for Kubernetes and service mesh
Give every service a short lived identity and make mTLS, rotation, and verification predictable in production.
Static secrets slow teams, blur accountability, and fail under audits. This book replaces ad hoc credentials with workload scoped identity using SPIFFE and SPIRE so services prove who they are on every connection without long lived keys.
You get a practical path from first SVIDs to multi cluster federation and audited CA operations. Each step is field tested, reversible, and aligned with how real platforms run.
Build a secure SPIRE install on Kubernetes, place server and agent correctly, and expose the Workload API through safe socketsIssue and rotate X.509 SVIDs with Envoy SDS, or deliver file based SVIDs with the SPIFFE CSI driver when stacks cannot run EnvoyUse the SPIRE Controller Manager with ClusterSPIFFEID and SPIFFEID to make registration declarative and reviewableDesign selectors around namespace and service account first, then labels when needed, to prevent over issuanceIntegrate Istio and Linkerd without surprises, set injector templates, configure gateways, and align authorization to SPIFFE IDsRun the OIDC Discovery Provider for JWT SVIDs, set issuer and audience correctly, and operate healthy verifier cachesPlan federation with bundle endpoints and profiles including https spiffe and https web, and scope federation to specific identitiesOperate high availability SPIRE with a SQL datastore, size Postgres, and set readiness and liveness probes that catch real failuresWatch the metrics that matter, issuance latency, SDS stream health, datastore pressure, and capacity signalsChoose UpstreamAuthority options, AWS PCA, GCP CAS, Vault, or cert manager, and decide where signing keys liveUse KeyManager with KMS or HSM, including AWS KMS patterns and a clear key handling postureRoll CAs without outages using a dual bundle window and a disciplined cutover planMigrate cleanly from the Istio default CA to SPIRE with a reversible step plan and namespace scoped changesOnboard VMs and hybrid workloads with cloud node attestors, AWS IID, GCP IIT, Azure MSI, and deliver identity to processes safelyWrite production runbooks for server loss, agent crash loops, and OIDC verifier breakages that on call engineers can execute fastProduce compliance evidence, a concrete threat model, change guards, and clear exit criteria that stand up in reviewThis is a code heavy guide with working YAML, HCL, Bash, and Systemd Unit examples that you can adapt directly to clusters and hosts.
