Dom Cloud - Classic Web Hosting Made Easy
Adaptable - The easiest way to deploy your FullStack App
Microtica
Coherence - The First Developer Experience Platform

原先在 Heroku 上架了 Line Bot, 使用上面的free PostgreSQL 跟 Redis. fly 剛好符合目前想要的使用情境, 所以這篇文章紀錄一下如何使用~

fly 免費方案的RAM約250MB, 想比Heroku的 500 MB 小了很多, 但 fly 不像 Heroku 會30分鐘沒使用就讓你的 server 停機

Install Flyctl

MAC

1
brew install flyctl

其他的 OS安裝方式可以參考 : https://fly.io/docs/hands-on/install-flyctl/

首先要先註冊再來是登入, 指令如下

1
2
flyctl auth signup
flyctl auth login

Launch and Deploy

Launch

可以直接到你的project下執行 flyctl launch 此時就他會詢問一些問題, 像是你的app name , 跟 server 要放在哪個國家區域等

  hkg (Hong Kong, Hong Kong)
  iad (Ashburn, Virginia (US))
  lax (Los Angeles, California (US))

  maa (Chennai (Madras), India)
  mad (Madrid, Spain)
  mia (Miami, Florida (US))

  scl (Santiago, Chile)
  sea (Seattle, Washington (US))
  sin (Singapore)
  sjc (San Jose, California (US))
  syd (Sydney, Australia)
  yul (Montreal, Canada)

最後會自動產生出fly.toml 跟 Dockerfile. 這邊是我的Django

ARG PYTHON_VERSION=3.7

RUN mkdir -p /app

COPY requirements.txt .
RUN pip install -r requirements.txt

COPY . .

RUN python manage.py makemigrations
RUN python manage.py collectstatic --noinput


EXPOSE 8000

# replace APP_NAME with module name
CMD ["gunicorn", "--bind", ":8000", "--workers", "2", "gogopowerkimibot.wsgi"]

Deploy

flyctl deploy , 就可以在 fly的 dashboard 看到程式碼正在部署了～如果有程式異動, 也可以直接打此指令

Create Postgre

跟上一步建立flyctl launch 差不多. 執行此指令flyctl postgres create, 最後他產生出一組連線資訊跟密碼. 記得要把它存起來, 要不然之後沒地方可以查到這些資訊

Create Redis

執行此指令flyctl redis create 記得要把它存起來, 要不然之後沒地方可以查到這些資訊

https://fly.io/docs/reference/redis/

其他指令:

1

4
flyctl redis list
flyctl redis status gogopowerkimi-redis
fly redis connect
fly redis delete {ID}

Secrets

當 Postgre 跟 Redis 都建立好時, 你可以把連線資訊或者你的環境變數寫入 .env 檔. 藉由 flyctl secrets import 去匯入 ex:

1
flyctl secrets import < .env.flyio

Fly Status

flyctl ssh console : 可以 ssh 進去 fly status --all : 看目前此 project 狀態

最後可以在你的 Dashborad上看到

Github Action

https://fly.io/docs/app-guides/continuous-deployment-with-github-actions/

1. 建立 Fly API Token

flyctl auth token 產生出一組 token, 並把它寫到你的 repositiry > settings > Secrets > Actions 取名為 FLY_API_TOKEN 如下圖

2. 建立 yml 檔

最後可以使用 Github Action, 當push時, 自動 deploy 在你的目錄 .github/workflows 資料夾下建立一個yml檔

# https://fly.io/docs/app-guides/continuous-deployment-with-github-actions/
name: Fly Deploy
on:   
  workflow_dispatch:
  push:
    branches:
      - flyio

env:
  FLY_API_TOKEN: ${{ secrets.FLY_API_TOKEN }}
jobs:
  deploy:
      name: Deploy app
      runs-on: ubuntu-latest
      steps:
        - uses: actions/checkout@v2
        - uses: superfly/flyctl-actions/setup-flyctl@master
        - run: flyctl deploy

之後只要push到 flyio branch 就會自動跑 action了
