2023 2Q update
Requirements & Constraints
Security/secrets not directly addressed - scope of other discussions, but relevant here - especially exposed via environment/files
Beyond config/repositories (stored externally via connectors/standard k8s objects), Only ephemeral storage - otherwise immutable. Declarative
One egeria server per pod
Aim for early results, build on what exists
top level server definition/type in k8s object, but most config remains in json document(s)
Integration use-case
Multiple stages: assembling a container (capabilities) vs deploying
Progress
Education on eclipse microprofile
Identified list of experiments/investigations
Example application which runs only a single server (no platform configuration). See PR . Addresses biggest pain point of having to run rest API calls to configure egeria server after container started
Repo created for experiments
Other recent achievements in k8s charts/containers
More connectors have an associated docker container, built using the same version of Egeria as that the connector pre-reqs
As part of Java 17/Egeria 4 work, containers are now using a Java 17 UBI-9 containers, which also now contains more tools (sdk, not just runtime) to facilitate monitoring/debugging - BUT we need to understand more around sizing (memory, limits, k8s...)
Atruvia's contributions to helm charts are merged which provides more configurability on the base chart (such as Kafka endpoints), and provision of a new lineage chart (which still needs some fixes)
For lab charts, storage class now configurable
'snippet' samples for helm charts
Other work in progress/to be done
Memory footprint - currently JVMs may grow until container environment kills them. Support added to limit resources, but default remains unlimited as unable to get a stable environment
