### SKA versions summary

[Config](SKA-CONFIG.md) summary of vlkb-soda releases to SKA.

Configuration summary for versions released to [SKA-harbor](https://harbor.srcdev.skao.int).

Based on Soda helm-charts v0.0.4:

* gatekeeper-ingress requires path-prefix: /soda

* soda/values.yaml sets: fsGroup, relativeSubPath and ACCESS_CONTEXT_ROOT 

| vlkb-soda version: | 1.6.2     | 1.7(.2)   | 1.8.3     |

|--------------------|:---------:|:---------:|:---------:|

| user in container  | root      | 1000:1000 | 1002:1002 |

| security: fsGroup  | n/a       | 1000      | 1002      |

| volume: relativeSubPath   | "surveys" | "datasets" | "datasets" |

| **SECURITY** (deprecated) | \<empty\> | \<empty\> | n/a |

| **ACCESS_CONTEXT_ROOT** defaults | n/a | "datasets" | "soda" |

| webapp-name (web.xml) | "soda" | "soda" | "sync" | 

Caveats:

Set ACCESS_CONTEXT_ROOT to empty string to avoid its default and

default used only when the var is not *defined* (only in 1.8.3).

In 1.6.2 and 1.7 default used only when ACCESS_CONTEXT_ROOT is not defined or is an empty string.
