Environment Variables

All SeqDesk environment variables use the SEQDESK_ prefix. They have the highest priority in the configuration resolution order, overriding config file and database values.

Value Parsing

Environment variables are parsed according to their target type:

Booleans — "true" / "false" (case-insensitive)
Numbers — parsed as integers for fields like scanDepth, cores, sessionTimeout
Arrays — comma-separated values, e.g. ".fastq.gz,.fq.gz,.fastq,.fq"
Strings — all other values

SeqDesk.com Admin Variables

These variables are used by the hosted SeqDesk.com admin service, not by an installed SeqDesk runtime. Configure them on the SeqDesk.com deployment when using install-profile administration features.

`INSTALL_PROFILE_STORAGE_SECRET`	For hosted install profiles	—	Encryption secret for install-profile access codes and encrypted profile secrets

Telemetry

These map to both the runtime config (telemetry.*) and the install-time heartbeat configuration. See Operational Telemetry for what gets reported.

Installer-only Variables

These variables are consumed by install-dist.sh and the seqdesk launcher before the app starts. They have no effect on a running app — they configure the install flow itself. Each one matches a CLI flag in the Full installer flag reference.
