❯ mina --version
Mina, version v1.2.3

config/deploy.rb

set :domain, "your_server" <这里是本地关于 server 的设置>
目标项目：nginx 指向这里 /www/wwwroot/data/dev.com/current
参考项目: https://github.com/alo7i/demo-dingtalk

set :deploy_to, "/www/wwwroot/data/dev.com"
set :repository, "git@github.com:alo7i/demo-dingtalk.git"
set :branch, "master"
set :shared_dirs, ["node_modules"] <特别注意这里的: shared_dirs 而不是 shared_paths>
set :keep_releases, 2 <实际上会备份3个 2 backup + 1 current>

require "mina/rails"
require "mina/git"
# require 'mina/rbenv'  # for rbenv support. (https://rbenv.org)
# require 'mina/rvm'    # for rvm support. (https://rvm.io)

# Basic settings:
#   domain       - The hostname to SSH to.
#   deploy_to    - Path to deploy into.
#   repository   - Git repo to clone from. (needed by mina/git)
#   branch       - Branch name to deploy. (needed by mina/git)

set :application_name, "demo-dingtalk"
set :domain, "lwb"
set :deploy_to, "/www/wwwroot/data/demo-dingtalk"
set :repository, "git@github.com:alo7i/demo-dingtalk.git"
set :branch, "master"
set :shared_dirs, ["node_modules"]
set :keep_releases, 2

# Put any custom commands you need to run at setup
# All paths in `shared_dirs` and `shared_paths` will be created on their own.
task :setup do
end

desc "Deploys the current version to the server."
task :deploy do
  # uncomment this line to make sure you pushed your local branch to the remote origin
  # invoke :'git:ensure_pushed'
  deploy do
    # Put things that will set up an empty directory into a fully set-up
    # instance of your project.
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'

    command "npm install"
    command "npm run build"
    # invoke :'bundle:install'
    # invoke :'rails:db_migrate'
    # invoke :'rails:assets_precompile'
    # invoke :'deploy:cleanup'
  end

  # you can use `run :local` to run tasks on local machine before of after the deploy scripts
  # run(:local){ say 'done' }
end

# For help in making your deploy script, see the Mina documentation:
#
#  - https://github.com/mina-deploy/mina/tree/master/docs

几个重要的 `tasks`

setup: 初始化项目，即生成 releases/shared 等目录
deploy: 将目标项目，执行 build 等命令，并 copy 到 releases/current 目录下
实际的操作，可以加个 deploy_only_build 省略掉 install 的步骤
老的文档里有个方法名为：queue 现在新方法名为 command
