gel v0.1.0

Databases

Gel (formerly EdgeDB) — a modern graph-relational database built on PostgreSQL, with a strict typed schema, a powerful query language (EdgeQL), migrations and built-in auth. Deployed as a single host-networked Nomad service (bundled PostgreSQL).

nomad-pack run gel --registry nomploy

…or one line (add registry + run)

curl -fsSL https://packs.nomploy.com/install.sh | sh -s -- gel

Needs nomad-pack on PATH. The script only adds the nomploy registry and runs this pack.

Back up this pack

This pack stores data in one Docker named volume: gel_data

restic

# Run on the node hosting this pack. Point restic at your repo first:
#   export RESTIC_REPOSITORY="s3:https://<account>.r2.cloudflarestorage.com/<bucket>"
#   export RESTIC_PASSWORD="<repo-password>"
#   export AWS_ACCESS_KEY_ID=<key>  AWS_SECRET_ACCESS_KEY=<secret>
restic backup \

rclone (sync to S3/R2)

rclone sync /var/lib/docker/volumes/gel_data/_data backup:<bucket>/gel_data

Paths assume the default Docker volume location (/var/lib/docker/volumes). Restore by stopping the job, restoring files into the same volume, and re-running the pack.

Readme

gel

Gel (formerly EdgeDB) is a modern graph-relational database built on top of PostgreSQL. It pairs a strict, typed schema with EdgeQL — an expressive query language designed to avoid SQL's awkwardness with nested/related data — plus first-class migrations, access policies, computed properties and built-in auth. You get Postgres' reliability with a far nicer developer experience.

This pack runs Gel as a single host-networked Nomad service. The image bundles its own PostgreSQL, so there's nothing else to deploy.

Deploy

nomad-pack run gel --registry=nomploy \
  --var server_password=$(openssl rand -hex 16)

Gel generates a self-signed TLS certificate on first boot and serves on port 5656. Connect with the gel CLI or a client library.

Configuration

Variable	Default	Description
`image`	`geldata/gel:latest`	Container image (pin a tag in production).
`port`	`5656`	Host port for the server.
`server_password`	`gel_change_me`	Password for the `admin` user — change this.
`tls_cert_mode`	`generate_self_signed`	TLS cert mode (auto self-signed by default).
`data_volume`	`gel_data`	Volume for data + bundled PostgreSQL.
`resources`	1000 MHz / 1024 MB	CPU and memory for the task.

The database (and its embedded PostgreSQL) persists in data_volume. Since the cert is self-signed, point clients at the server with TLS verification set to insecure, or mount a trusted certificate and set tls_cert_mode=require_file.
