An AEM OSGi adapter and its containerized integration API both need explicit endpoint and timeout configuration. They should share a documented contract without sharing a configuration mechanism or assuming that AEM itself runs in the cluster.
Kubernetes Configuration Strategy.
Design one deployable image with explicit environment inputs for AEM-adjacent services. This architecture separates ordinary configuration, sensitive credentials and runtime validation while connecting the same discipline to cloud-ready AEM service design.
Representative engineering design, not a verified client delivery record. Implementation steps and validation checks describe the proposed approach; no measured results are claimed.
- Image digest
- Environment config
- Secret reference
- Pod startup
- Validation
- Controlled rollout
Logical configuration assembly. AEM OSGi configuration stays separate from Kubernetes workload configuration.
Separate deployment platforms, consistent principles
Environment assumptions become hidden code
Hard-coded hosts, copied credentials and environment-specific images make promotion difficult to audit. Defaults that silently select a developer endpoint can also make a deployment appear healthy while connecting to the wrong system.
Public settings and secrets take separate paths
Use ConfigMaps for non-sensitive inputs and a controlled secret-delivery mechanism for credentials. Kubernetes Secret values are not protected merely by base64 encoding; access controls, storage protection and restrictions on workload access are separate responsibilities.
Validate configuration before accepting traffic
Define required fields, accepted formats and safe bounds for connection pools and timeouts. Promote a digest-pinned image alongside versioned configuration references, and fail startup clearly when required inputs are missing.
- Record a non-sensitive configuration revision in deployment metadata.
- Keep credentials out of Git, logs, image layers and diagnostic dumps.
- Document whether each setting is read at startup or reloaded, rather than assuming a ConfigMap update changes a running process.
Rotate with a deliberate activation step
Provision the new credential, update its reference and validate authentication before retiring the previous credential where the upstream system permits overlap. Environment-variable consumers need replacement processes; mounted-file consumers still need an application reload strategy.
- Issue credential
- Update reference
- Reload / replace
- Validate
- Revoke old
Rotation ordering depends on the external system's support for overlapping credentials.
Track drift without exposing secret values
Compare desired configuration references with the running release and inspect only redacted diagnostic information. Assign ownership for expiration, rotation failures and emergency access; a secret object alone does not supply those operational processes.
Dynamic reload versus controlled replacement
Reloading can avoid a rollout but adds application complexity around partial updates and connection renewal. Process replacement is easier to reason about, provided availability and dependency capacity support it.
Prove configuration changes are observable and reversible
The design aims for clearer environment separation and consistent deployment inputs. Evidence should show what changed without revealing sensitive values.
- Start the service with a missing or malformed required setting and verify an actionable, redacted error.
- Rotate a credential during traffic and inspect old and new connection behavior.
- Revert an ordinary configuration revision and verify the image digest is unchanged.
- Audit permissions so unrelated workloads cannot read the service's credentials.
Configuration is a versioned interface
Cloud readiness depends on explicit assumptions, not on moving values into a different file. The contract must include ownership, validation, activation and recovery for every consequential setting.
