GroROTI 🍖

Open source repository of G(r)oROTI 🍖, a selfhosted Return On Time Invested web application written in Go

The UI and functionalities are really basic. Here is a quick overview:

• create an anonymous ROTI in seconds
• find latest ROTIs in homepage (can be disabled with "Hide this ROTI" checkbox)
• Enable / disable textbox feedbacks in votes with a checkbox
• share the link (or QR code) with people that need to vote
• by default, ROTIs are cleaned 30 days after creation
• golang (memory, gc...), http (latency, codes...) and groroti metrics are exposed on /-/metrics path
• export ROTI results with a csv or a PNG file

Run it!

Locally with the binary

You can download the linux binary for arm64 and amd64 in the releases page. To build it yourself, see building section of this page.

With the docker image

Public docker images are available on hub.docker.com.

You can pull/run the latest version by running:

docker pull deezer/groroti:latest
docker run -p 3000:3000 -e FRONTEND_URL=https://groroti.mydomain.tld deezer/groroti

Aside from frontend URL, to customize other parameters, see Configuration section on this page.

Deploy with Kubernetes

You can deploy the helm chart in this repository with (change your values with your own):

cd helm
helm install groroti -f values.yaml .
#or if already installed
helm upgrade groroti -f values.yaml .

Deploy on Clever Cloud

Install clever-tools (npm i -g clever-tools), create an account on Clever cloud website. Then login in a terminal

clever login

Create an app on clever cloud

clever create --type go groroti

Set SERVER_PORT to match clever cloud golang image (8080 instead of 3000)

clever env set SERVER_PORT 8080

Get URL (from clever cloud console) of the app and then change the FRONTEND_URL

clever env set FRONTEND_URL "https://app-xxx-xxx-xxx-xxx-xxx.cleverapps.io"

Or better yet, add a domain and put a DNS record on it

clever domain add groroti.mydomain.tld
clever env set FRONTEND_URL "https://groroti.mydomain.tld"

Tell clever cloud to use gomod method to install dependancies instead of goget (deprecated, will fail in this case)

clever env set CC_GO_BUILD_TOOL gomod

Deploy on clever cloud

clever deploy

Configure it!

You can customize some of the features of GroROTI:

• configuration file path - default is "config.toml", can be overridden with GROROTI_CONFIG environment variable
• server listening address - default is "0.0.0.0", can be overridden with SERVER_ADDR environment variable or server_addr in configuration file
• server listening port - default is "3000", can be overridden with SERVER_PORT environment variable or server_port in configuration file
• url for internal links - default is "http://localhost:3000" but QR codes won't work (obviously). You can override this with FRONTEND_URL environment variable or frontend_url in configuration file
• vote input step - default is "0.5" but this can be customized (to allow only int for example) with VOTE_STEP environment variable or vote_step in configuration file
• qr code size - default is "384" (in pixels), can be overridden with QR_CODE_SIZE environment variable or qr_code_size in configuration file
• clean over time - when a new ROTI is created, remove all ROTIs that are older than xxx. Default is 30 (in days), can be overridden with CLEAN_OVER_TIME environment variable or clean_over_time in configuration file

Build it!

Prerequisites

This software requires Go 1.22+

Run dev version

The Makefile has an alias to help you run the server in dev mode with a simple make dev command

make dev
SERVER_ADDR=127.0.0.1 SERVER_PORT=3000 FRONTEND_URL=http://localhost:3000 go run main.go
2022/05/09 22:41:56 Start listening on 127.0.0.1:3000

All building operations for the project (both binaries and docker images) are done using GoReleaser by default.

goreleaser

You can build it on any commit using the --snapshot goreleaser option:

make snapshot

You can then test/run locally using the binary of the docker image:

#binary
dist/GroROTI_linux_amd64_v1/groroti

#docker image
docker run -p 3000:3000 docker.io/deezer/groroti:latest-amd64

goreleaser for Deezer staff

Deezer staff can push a new release by tagging the git repository to create a new release, and running goreleaser:

git tag -a 1.0.0 -m "1.0.0 release"
git push origin 1.0.0
export GITHUB_TOKEN="ghx_xxxxxxxxxxxxxxxxxx" #or use ~/.config/goreleaser/github_token file
goreleaser release

manually

Should you decide to not use GoReleaser to build your binary / image, you should know that the Docker image requires the binary to be builded with -extldflags '-static' ldflags

go build -ldflags="-extldflags '-static'"
docker build -t localgroroti .
docker run -p 3000:3000 localgroroti
