Question

愚蠢的问题，但我们有一个破碎的卡皮斯特拉诺食谱，我想验证我们没有使用after＆amp; before不正确？

之前和之后做这些任务属于:deploy命名空间块或其外部？我看到了here的两个例子。

这是有问题的deploy.rb：

的摘录

namespace :deploy do
  task :start do ; end
  task :stop do ; end
  task :restart, :roles => :app, :except => { :no_release => true } do
    run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
  end

  # copy database.yml into project
  task :copy_database_config do
    production_db_config = "/Library/RoRconfig/#{application}.yml"
    run "cp #{production_db_config} #{current_release}/config/database.yml"
    `puts "replaced database.yml with live copy"` 
  end

  task :pipeline_precompile do
    run "cd #{release_path}; RAILS_ENV=production rake assets:precompile"
  end

  after "deploy:update_code", "deploy:pipeline_precompile"         ### <---
  before "deploy:finalize_update", "deploy:copy_database_config"   ### <---
end

Answer 1

我使用类似于以下的设置：

after :deploy, "deploy:update_code", "deploy:pipeline_precompile"
before :deploy, "deploy:finalize_update", "deploy:copy_database_config"

namespace :deploy do
  task :start do ; end
  task :stop do ; end
  task :restart, :roles => :app, :except => { :no_release => true } do
    run "#{try_sudo} touch #{File.join(current_path,'tmp','restart.txt')}"
  end

  # copy database.yml into project
  task :copy_database_config do
    production_db_config = "/Library/RoRconfig/#{application}.yml"
    run "cp #{production_db_config} #{current_release}/config/database.yml"
    `puts "replaced database.yml with live copy"` 
  end

  task :pipeline_precompile do
    run "cd #{release_path}; RAILS_ENV=production rake assets:precompile"
  end
end

Answer 2

根据https://capistranorb.com/documentation/getting-started/before-after/上capistrano的文档，这是它们在：deploy命名空间的内部和外部建议的方式：

# call an existing task
before :starting, :ensure_user
after :finishing, :notify

# or define in block
namespace :deploy do
  before :starting, :ensure_user do
    #
  end

  after :finishing, :notify do
    #
  end
end

但是，请注意不要将这些挂钩放在您导入的自定义capistrano rake文件中，因为加载顺序可能使其不存在。

在卡皮斯特拉诺食谱中放置“之前”和“之后”的位置？
