Configuration

All configuration via environment variables in the pipeline deployment.

S3 Access (Required)

Variable	Description
`S3_ENDPOINT`	VAST S3 data VIP (e.g., `http://172.200.201.67`). No trailing slash.
`S3_ACCESS_KEY`	S3 access key for source bucket
`S3_SECRET_KEY`	S3 secret key

Variable	Description	Default
`VAST_DB_ENDPOINT`	DataBase endpoint	Falls back to `S3_ENDPOINT`
`VAST_DB_ACCESS_KEY`	DataBase access key	Falls back to `S3_ACCESS_KEY`
`VAST_DB_SECRET_KEY`	DataBase secret key	Falls back to `S3_SECRET_KEY`
`VAST_DB_BUCKET`	Database-enabled bucket	`sergio-db`
`VAST_DB_SCHEMA`	Schema name (shared with exr-inspector)	`exr_metadata_2`

Variable	Description	Default
`KAFKA_BROKER`	Kafka broker address	`vastbroker:9092`
`KAFKA_TOPIC`	Topic for proxy completion events	`spaceharbor.proxy`

Variable	Description	Default
`OCIO_CONFIG_PATH`	Optional OCIO config file. If set and valid, enables ACES colorspace names. If unset or missing, uses oiiotool built-in transforms (linear, sRGB, Rec709).	(unset)
`OIIO_TIMEOUT`	Subprocess timeout in seconds for oiiotool and ffmpeg	`300`
`DEV_MODE`	Skip Kafka publishing and S3 uploads when `true`	`false`

Resource	Recommended	Notes
CPU request	500m	ffmpeg + color transform are CPU-bound
CPU limit	2000m	ffmpeg parallelizes internally
Memory request	512Mi	Full EXR in memory for color transform
Memory limit	2Gi	4K EXR + resize intermediates
Ephemeral disk	5Gi	Source download + intermediates + outputs
Timeout	600s	4K EXR encode can take 30-60s
RPS factor	1	One file per pod (CPU-bound)
minScale	1	Avoid cold start (loads oiiotool + ffmpeg)
maxScale	5	Cap memory (5 pods x 2GB = 10GB)
Delivery	unordered	Each file is independent
Scale-down delay	60s	Avoid thrashing during burst ingestion
