Automating APISIX TLS Secrets with CertManager using Argo Events: A Hands-On Guide
- When integrating TLS certificates with APISIX in Kubernetes, a challenge arises due to format discrepancies between cert-manager and APISIX.
- Solution involves using Argo Events to automate certificate updates in APISIX by transforming secrets and triggering changes.
- Tools and technologies used include APISIX, cert-manager, and Argo Events for managing and updating certificates.
- Cert-manager installation and Argo Events setup ensure automation of TLS certificate injection into APISIX.
- Configuration steps include creating service accounts, configuring EventBus, setting up event sources, and creating secrets.
- Process involves continuous monitoring for TLS secret changes, transformation, and injection into APISIX in the required format.
- Testing involves creating TLS certificates, verifying updates on the APISIX dashboard, and debugging if needed.
- Manual intervention is required to sync existing certificates with APISIX by recreating certificates through Cert-Manager.
- Argo Events plays a crucial role in automating the certificate management process, ensuring real-time updates in APISIX.
- Overall, the solution provides fully automated certificate synchronization, real-time updates, and seamless integration with Kubernetes.
