grafana v0.1.0

Observability

Grafana — the open observability platform for dashboards and visualization, deployed as a host-networked Nomad service with a persistent Docker volume for its database and plugins.

nomad-pack run grafana --registry nomploy

…or one line (add registry + run)

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

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: grafana_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 \
  /var/lib/docker/volumes/grafana_data/_data

rclone (sync to S3/R2)

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

grafana

Grafana as a host-networked Nomad service with a persistent Docker named volume for its SQLite database and plugins.

Usage

nomad-pack registry add nomploy github.com/Nomploy/nomad-packs
nomad-pack run grafana --registry nomploy --var admin_password=change-me

Or in nomploy: Create → Nomad Pack, pick grafana from the Nomploy registry.

Variables

Variable	Default	Description
`job_name`	`grafana`	Nomad job name
`image`	`grafana/grafana:latest`	Container image
`port`	`3001`	Host port (avoids the panel's `:3000`)
`count`	`1`	Keep at 1 (local SQLite DB)
`admin_user`	`admin`	Initial admin user
`admin_password`	`admin`	Change this
`root_url`	`""`	Public URL when fronted by a domain
`data_volume`	`grafana_data`	Docker named volume for `/var/lib/grafana`
`constraints`	`[]`	Pin placement so the local volume stays put
`resources`	`{cpu=500, memory=512}`	Task resources

Notes

Persistence: uses a Docker named volume — a fresh one inherits the image's /var/lib/grafana ownership (uid 472), so Grafana can write it (an alloc bind would be root-owned and fail). Pin the job with constraints so it lands on the node holding the volume.
Set root_url when serving Grafana behind a domain/reverse proxy so its links and OAuth redirects are correct.
