使用distillery&&docker 部署phoenix 应用

distillery 发布了2.0 了，有好多的新的功能

config prodiver 进行环境变量的配置
appup tansforms 插件系统，方便在release 构建的时候进行修改
mix release.gen.appup 新的mix task
pid 文件

demo 是一个简单的phoenix 同时使用docker 进行构建

项目创建

mix phx.new --no-ecto phoenix_distillery

添加distillery 支持

mix.exs

defp deps do

    [ ...,

      {:plug_cowboy, "~> 1.0"}, // 需要添加，不然构建会有问题

      {:distillery, "~> 2.0"}

       ]

end

配置phoenix endpoint 信息

config/prod.exs

config :phoenix_distillery, PhoenixDistilleryWeb.Endpoint,

  http: [port: {:system, "PORT"}],

  url: [host: "localhost", port: {:system, "PORT"}], # This is critical for ensuring web-sockets properly authorize.

  cache_static_manifest: "priv/static/cache_manifest.json",

  server: true,

  root: ".",

  version: Application.spec(:phoenix_distillery, :vsn)

构建

mix deps.get --only prod

MIX_ENV=prod mix compile

cd assets

yarn build build --production

cd ..

mix phx.digest

distillery release

进行release 初始化配置

mix release.init

MIX_ENV=prod mix release

运行

PORT=4001 _build/prod/rel/phoenix_distillery/bin/phoenix_distillery foreground

docker 构建支持

构建&&运行

docker-compose build && docker-compose up -d

效果

说明

2.0 有好多新特性的添加，后边会有简单的使用demo，功能很强大
