linux - fly.io 的基本用法 flyctl launch deploy view ssl domain

访问量: 66

refer to: https://fly.io/docs/speedrun/

fly.io 是一个类似于heroku, 是一个PAAS平台。 也就是说,目的是为了担任一部分的运维工作。

传统的方式:  PUSH 代码 +  虚拟机

fly.io , heroku 的方式:  在开发者的本地使用 命令行, 来上传代码和 启动服务器

注册和登录:  略。 但是记得要验证邮箱。 否则会报错:Error You must verify your email address to activate your account. https://fly.io/dashboard/parallelid/billing

记得要验证,否则后面无法使用

安装 flyctl

curl -L https://fly.io/install.sh | sh

把本地的一个简单的应用,部署到远程  

例如一个sinatra 应用。

app.rb

#!/usr/bin/env ruby

require 'rubygems'
require 'bundler/setup'
require 'sinatra'

get '/' do
  "<h1>Hello From Ruby on Fly!</h1>"
end

get '/:name' do
  "<h1>Hello From Ruby on Fly!</h1></br>and hello to #{params[:name]}"
end

Gemfile:
source 'https://rubygems.org'

ruby '3.1.0'
gem 'sinatra'
gem 'puma'

config.ru

require './app.rb'

run Sinatra::Application

本地运行:

$ rackup
Puma starting in single mode...
* Puma version: 5.6.4 (ruby 3.1.0-p0) ("Birdie's Version")
*  Min threads: 0
*  Max threads: 5
*  Environment: development
*          PID: 300873
* Listening on http://127.0.0.1:9292
* Listening on http://[::1]:9292
Use Ctrl-C to stop

在远程运行   flyctl  launch (正餐开始了)

这里会问: app name, organization, 部署到哪个地区(美国,法国。。。)

可以发现,在本地代码文件夹,会多出一个文件: fly.toml 

内容如下:

# fly.toml file generated for test-hi on 2022-06-02T11:22:18+08:00

app = "test-hi"

kill_signal = "SIGINT"
kill_timeout = 5
processes = []

[build]
  builder = "heroku/buildpacks:20"

[env]
  PORT = "8080"

  allowed_public_ports = []
  auto_rollback = true

  http_checks = []
  internal_port = 8080
  processes = ["app"]
  protocol = "tcp"
  script_checks = []

    hard_limit = 25
    soft_limit = 20
    type = "connections"

    force_https = true
    handlers = ["http"]
    port = 80

  [[services.ports]]
    handlers = ["tls", "http"]
    port = 443

  [[services.tcp_checks]]
    grace_period = "1s"
    interval = "15s"
    restart_limit = 0
    timeout = "2s"

此时,后台就会多出一个app 来。  

可以看到他的 cpu 核心数目 等等。

点击上面的红框,就可以看到 该 部署(或者叫虚拟机)的详细情况,如下图所示:

点击上图中的 hostname , (我们发现 fly 自动分配了一个 域名给我们使用   <app-name>.fly.dev )

就可以查看我们刚才弄的 app 了。

(根据官方文档,也可以使用命令行来打开 这个网址)

设置ssl 域名

点击左侧的 certificates, 输入咱们的域名, 然后点击View, 根据提示进行配置:

点击后是这样:

deploy 之前: 不要使用 HTTP_PROXY,  HTTPS_PROXY 这样的东东

会直接导致无法部署,因为proxy是不会正确识别 fly.io的各种服务器和IPV6地址的

deploy;  使用日志

LOG_LEVEL=debug fly deploy --remote-only  务必 加上这个LOG_LEVEL=debug

务必保证在你的本地是可以运行生产模式的。 rails s -e production

一定要保证这一点,否则fly.io会报错。 而且报错的位置不同
有的是在 console中报错的,有的是在web 页面中的dashboard 报错的。

遇到卡住的问题怎么办?  fly.io Error error connecting to docker: remote builder app unavailable

往往是由于 builder 所在的region跟当前app的region不是一个造成的。

解决办法: 删掉这个builder,

https://community.fly.io/t/deployment-issue-remote-builder-app-unavailable/5126/7

遇到问题怎么办?  看日志,拆分命令

1. 先是看到这个错误,完全没有头绪:

 => ERROR [gems 3/3] RUN bundle install &&  rm -rf vendor/bundle/ruby/*/cache                                                                                                          0.9s
------
 > [gems 3/3] RUN bundle install &&  rm -rf vendor/bundle/ruby/*/cache:

------
DEBUG result image:<nil> error:error building: executor failed running [/bin/bash -c bundle install &&  rm -rf vendor/bundle/ruby/*/cache]: exit code: 18
Error error building: executor failed running [/bin/bash -c bundle install &&  rm -rf vendor/bundle/ruby/*/cache]: exit code: 18

然后,我们就把对应的Dockerfile 做个改动, 只运行一个:

-RUN bundle install && rm -rf vendor/bundle/ruby/*/cache
+#RUN bundle install && rm -rf vendor/bundle/ruby/*/cache
+RUN bundle install --verbose  (现在使用了这个 --verbose 参数)

然后我们就看到原因了,是ruby版本号不对。

连接 fly.io 上的postgres 数据库

flyctl postgres connect -a <nft-contract-api-db>

后面的是db的名字, 也就是app name,  在后台中可以看到。

连到之后, 就是正常的postgres操作了。

默认: 会产生一个 数据库,名称和app name 是一样的。记得修改  config/database.yml ( 在 dockerfile 中)

例如增加下面这句

82
83 COPY . .
84 COPY ./config/database.yml.fly.io ./config/database.yml
85
86 RUN bundle exec rails assets:precompile

如何部署Rails 应用?

为Rails项目增加 fly.toml ,内容如下:

# fly.toml file generated for pns-nft-contract-api on 2022-06-02T15:37:11+08:00

app = "pns-nft-contract-api"

kill_signal = "SIGINT"
kill_timeout = 5
processes = []

[build]

  [build.args]
    BUNDLER_VERSION = "2.3.3"
    NODE_VERSION = "14"
    RUBY_VERSION = "3.1.1"

[deploy]
  release_command = "bundle exec rails db:migrate"

[env]
  PORT = "8080"
  SERVER_COMMAND = "bundle exec puma -C config/puma.rb"

[experimental]
  allowed_public_ports = []
  auto_rollback = true

[[services]]
  http_checks = []
  internal_port = 8080
  processes = ["app"]
  protocol = "tcp"
  script_checks = []

  [services.concurrency]
    hard_limit = 25
    soft_limit = 20
    type = "connections"

  [[services.ports]]
    force_https = true
    handlers = ["http"]
    port = 80

  [[services.ports]]
    handlers = ["tls", "http"]
    port = 443

  [[services.tcp_checks]]
    grace_period = "1s"
    interval = "15s"
    restart_limit = 0
    timeout = "2s"

[[statics]]
  guest_path = "/app/public"
  url_prefix = "/"

如何部署静态网页? https://fly.io/docs/getting-started/static/

1. 把项目在本地成功

yarn install  

yarn dev 

yarn build

就会得到静态文件夹, 有的是dist, 有的是 public, 有的是 build , 叫法不一样。

2. 创建Dockerfile  (因为fly.io 需要用gostatic 来运行, 注意下面的COPY后面的参数,必须是正确的  (public, dist... ) )

FROM pierrezemb/gostatic
COPY ./public/ /srv/http/

3. flyctl launch

做一系列选择,填写app 的名称(这个最重要) 会生成一个 fly.toml文件。

(一定要先有Dockerfile , 再 生成 fly.toml , 否则生成的fly.toml 中包含了build 模块,会导致占用大量的时间和空间,

另外,需要修改 fly.toml中的 端口为8043, 因为gostatic 会用这个端口,而不是8080 .

4. flyctl deploy

对于静态文件,部署需要一些时间(还是会生成一个docker的。所以需要等一会儿)

部署静态文件的完整日志 (大概5分钟吧。主要是传140MB的内容到docker )

如何查看log?

flyctl logs

如何 登录SSH?

flyctl ssh console  即可(前提是 这个APP需要成功运行起来)进入后跟linux的操作系统一样的。

WORKDIR /app   这个是dockerfile中定义的内容。

所以我们 ssh 之后,来这里就可以看到了 

1234? 6789? 这个是啥APP?

是临时性的app, 直接删掉就好

部署Redis

redis是Rails项目必须用到的东东

千万不要参考 官方文档  https://fly.io/docs/reference/redis/ ,这个步骤会生成一个 有问题的 fly.toml  ,无法完成部署

要参考这个: https://github.com/fly-apps/redis  后面其他的demo也都是一样的

其实非常简单, 创建一个文件夹,例如叫 my_redis, 然后增加这个 fly.toml 文件;

app = "siwei-redis"

[build]
  image = "flyio/redis:6.2.6"

[mounts]
  destination = "/data"
  source = "redis_server"

然后创建 volume:

flyctl volumes create redis_server --size 1  (创建容量为1G的 名称为 redis_server 的volume)

flyctl volumes list  ( 查看 volume列表)

然后为Redis创建 password

fly secrets set REDIS_PASSWORD=siweidaydayup
fly secrets list

flyctl deploy  (可以看到大概20秒就部署成功了。如果一直卡在  monitoring ... 那一步的时候,就要登录web console 去看出现的log 了)

fly deploy

==> Creating release
--> release v1 created

--> You can detach the terminal anytime without stopping the deployment
==> Monitoring deployment

--> v1 deployed successfully

登录 REDIS SSH: 

flyctl ssh console

/ # redis-cli -h siwei-redis.internal
pns-redis.internal:6379> auth (password)daydayup
OK
pns-redis.internal:6379> keys *
(empty array)

注意:以上步骤创建的是IP地址对外不公开的redis.  使用的地址是   siwei-redis.internal 

如果要创建对外可以使用IP的话(推荐),可以用这个fly.toml:

app = "pns-redis"

[build]
  image = "flyio/redis:6.2.6"

[mounts]
  destination = "/data"
  source = "redis_server"

[[services]]
internal_port = 6379
protocol      = "tcp"

  [[services.ports]]
  port     = "6379"

  [[services.tcp_checks]]
  interval = 10000
  timeout  = 2000

使用fly.io 创建mongo  (部署Docker)

参考:
https://fly.io/docs/getting-started/dockerfile/  和
https://community.fly.io/t/unable-to-connect-to-mongodb-instance/4837

fly.io 官方中没有支持mongo的demo , 不过我们可以通过创建docker来创建mongo

创建一个文件夹 fly.io.mongo

进来, 创建文件  Dockerfile

FROM mongo:latest

创建volume

flyctl volumes create mongodb --size 1

然后创建 fly.toml , 内容如下;

app = "siwei-mongo"

[build]
  image = "mongo:5.0.6"

[mounts]
  destination = "/data/db"    # 这个很重要,mongodb的docker默认是放在 /data/db目录下的
  source = "mongodb"

[[services]]
  internal_port = 27017
  protocol      = "tcp"

  # 想要允许外网访问的话,就把这个打开。
  [[services.ports]]
  port     = "64000"

  [[services.tcp_checks]]
  interval = 10000
  timeout  = 2000

然后部署:

$ fly deploy

就可以发现,很快跑起来了。

$ fly ssh console 

就可以登录了。

如何restore mongodb  

使用 mongorestore --host=<公共ip> --port=<端口> --archive=<file> 就可以了
前提是需要把mongo的 27017端口对外开放。

fly wireguard create    可以创建一个wire tunnel ,会得到下面的内容:

 fly wireguard create
? Select organization: parallxxxx (paralxxx)
Creating WireGuard peer "interactive-DESKTOP-GG23M21-shensiwei-sina-com-733" in region "hkg" for organization parallelid

!!!! WARNING: Output includes private key. Private keys cannot be recovered !!!!
!!!! after creating the peer; if you lose the key, you'll need to remove    !!!!
!!!! and re-add the peering connection.                                     !!!!
? Filename to store WireGuard configuration in, or 'stdout':  stdout

[Interface]
PrivateKey = t15Gk4qBOoGlwJff+wJzcqjxxx
Address = fdaa:0:6bbf:a7b:9xxxx
DNS = fdaa:0:6bbf::3

[Peer]
PublicKey = e1Yk8div9bnazZD7Mo48x8C+x2xxx
AllowedIPs = fdaa:0:6bbf::/48
Endpoint = hkg2.gatewaxxxxx
PersistentKeepalive = 15

安装  sudo apt install wireguard-tools openresolv  ( 参考: https://fly.io/docs/reference/private-networking/)

关于网络问题

你的app叫啥名字,网络就是 xx.internal,  例如上面的redis,  app = 'xx', 那么内网ip就是  xx.internal,  可以被直接访问
