Supabase (Firebase)
Module:
Supabase —— Build in a weekend, Scale to millions
Supabase 口号是：“花个周末写写，随便扩容至百万”
Supabase 是一个开源的 Firebase 替代，基于 PostgreSQL 提供了认证，开箱即用的 API，边缘函数，实时订阅，存储，向量嵌入能力。
Supabase 已经于 2024.04.15 正式宣布进入 GA 状态，Pigsty 也于第一时间跟进并提供了自托管的支持。
快速上手
要使用现有 PostgreSQL 实例运行 Supabase，请使用 supa.yml 配置模板创建数据库集群。
然后使用 docker-compose 模板启动无状态的部分即可：
cd ~/pigsty/app/supabase; make up # https://supabase.com/docs/guides/self-hosting/docker
然后您就可以通过 http://<admin_ip>:8000 访问 Supabase Studio 管理界面，默认的用户名是 supabase，密码是 pigsty。
你可以通过配置 infra_portal 将 Supabase WebUI 通过 Nginx 和 SSL 对外暴露。
PostgreSQL置备
Supabase 需要特定的 PostgreSQL 扩展插件，以及一系列角色与权限才可以正常工作。请注意，这些扩展插件目前仅在 Pigsty 扩展插件仓库中针对 EL8/EL9, Debian12/Ubuntu22.04 提供。
Pigsty 可以通过声明式配置，替用户置备好所需的 PostgreSQL 集群：supa.yml。
例如，下面的集群 pg-meta 就配置了 Supabase 所需的用户，数据库，扩展插件，权限等信息：
# supabase example cluster: pg-meta
# this cluster needs to be migrated with app/supabase/migration.sql :
# psql postgres://supabase_admin:[email protected]:5432/supa -v ON_ERROR_STOP=1 --no-psqlrc -f ~pigsty/app/supabase/migration.sql
pg-meta:
hosts: { 10.10.10.10: { pg_seq: 1, pg_role: primary } }
vars:
pg_cluster: pg-meta
pg_users:
# supabase roles: anon, authenticated, dashboard_user

- { name: service_role ,login: false ,bypassrls: true }
# supabase users: please use the same password

- { name: authenticator ,password: 'DBUser.Supa' ,pgbouncer: true ,inherit: false ,roles: [ authenticated ,anon ,service_role ] }

- { user: all ,db: supa ,addr: all ,auth: pwd ,title: 'allow supa database access from entire world' } # not safe!
请注意在 supa 数据库定义中的 baseline: supa.sql，它会在集群初始化的时候执行 files/supa.sql，完成一部分数据库迁移任务，这些模式定义是来自 Supabase的初始化脚本，基本是固定的，会自动执行。
你还需要在集群初始化后，运行另一部分初始化脚本： migration.sql，这一部分的模式定义是可能会变化的，是从 supabase/postgres/migrations/db/migrations 目录中按照执行顺序合并而来，并根据 Pigsty 的实际情况进行调整得到的模式变更脚本。
当前的最新版本：同步至 20231013070755
为了运行这个模式迁移 SQL，你可以使用 psql 命令行工具，连接到 pg-meta 集群，并执行：
PGURL=postgres://supabase_admin:[email protected]:5432/supa
psql ${PGURL} -v ON_ERROR_STOP=1 --no-psqlrc -f ~/pigsty/app/supabase/migration.sql
成功执行后，这个 PostgreSQL 数据库集群就可以用于 Supabase 了！
无状态的部分
您可以在 https://supabase.com/docs/guides/self-hosting/docker#generate-api-keys 生成 JWT Secret，ANON_KEY 以及 SERVICE_KEY.
Supabase stateless part is managed by docker-compose, the docker-compose file we use here is a simplified version of github.com/supabase/docker/docker-compose.yml.
Everything you need to care about is in the .env file, which contains important settings for supabase. It is already configured to use the pg-meta.supa database by default, You have to change that according to your actual deployment.
############
# Secrets - YOU MUST CHANGE THESE BEFORE GOING INTO PRODUCTION
############
# you have to change the JWT_SECRET to a random string with at least 32 characters long
# and issue new ANON_KEY/SERVICE_ROLE_KEY JWT with that new secret, check the tutorial:
# https://supabase.com/docs/guides/self-hosting/docker#securing-your-services
JWT_SECRET=your-super-secret-jwt-token-with-at-least-32-characters-long
ANON_KEY=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyAgCiAgICAicm9sZSI6ICJhbm9uIiwKICAgICJpc3MiOiAic3VwYWJhc2UtZGVtbyIsCiAgICAiaWF0IjogMTY0MTc2OTIwMCwKICAgICJleHAiOiAxNzk5NTM1NjAwCn0.dc_X5iR_VP_qT0zsiyj_I_OZ2T9FtRU2BBNWN8Bu4GE
SERVICE_ROLE_KEY=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyAgCiAgICAicm9sZSI6ICJzZXJ2aWNlX3JvbGUiLAogICAgImlzcyI6ICJzdXBhYmFzZS1kZW1vIiwKICAgICJpYXQiOiAxNjQxNzY5MjAwLAogICAgImV4cCI6IDE3OTk1MzU2MDAKfQ.DaYlNEoUrrEn2Ig7tqibS-PHK5vgusbcbo7X36XVt4Q
############
# Dashboard - Credentials for the Supabase Studio WebUI
############
DASHBOARD_USERNAME=supabase # change to your own username
DASHBOARD_PASSWORD=pigsty # change to your own password
############
# Database - You can change these to any PostgreSQL database that has logical replication enabled.
############
POSTGRES_HOST=10.10.10.10 # change to Pigsty managed PostgreSQL cluster/instance VIP/IP/Hostname
POSTGRES_PORT=5432 # you can use other service port such as 5433, 5436, 6432, etc...
POSTGRES_DB=supa # change to supabase database name, `supa` by default in pigsty
POSTGRES_PASSWORD=DBUser.Supa # supabase dbsu password (shared by multiple supabase biz users)
Usually you’ll have to change these parameters accordingly. Here we’ll use fixed username, password and IP:Port database connstr for simplicity.
The postgres username is fixed as supabase_admin and the password is DBUser.Supa, change that according to your supa.yml
And the supabase studio WebUI credential is managed by DASHBOARD_USERNAME and DASHBOARD_PASSWORD, which is supabase and pigsty by default.
The official tutorial: Self-Hosting with Docker just have all the details you need.
Hint
You can use the Primary Service of that cluster through DNS/VIP and other service ports, or whatever access method you like.
You can also configure
supabase.storageservice to use the MinIO service managed by pigsty, too
Once configured, you can launch the stateless part with docker-compose or make up shortcut:
cd ~/pigsty/app/supabase; make up # = docker compose up
对外暴露服务
Supabase Studio 提供了一个 Web 管理界面，默认监听 8000 端口，你可以将其加入 infra_portal，来对外 暴露服务。
infra_portal: # domain names and upstream servers
# ...
supa : { domain: supa.pigsty ,endpoint: "10.10.10.10:8000", websocket: true }
To expose the service, you can run the infra.yml playbook with the nginx tag:
./infra.yml -t nginx
Make suare supa.pigsty or your own domain is resolvable to the infra_portal server, and you can access the supabase studio dashboard via https://supa.pigsty.
