Capistrano 中的部署用户是什么？

Question

我正试图了解 Capistrano。

什么是 ssh 部署用户？我有带 ssh 访问权限的共享托管空间，我通常使用 ssh myuser@domain.com 并使用 RSA 私钥进行身份验证。

这是我尝试进行部署的输出

这是我的 deploy.rb

# config valid only for Capistrano 3.3.5
lock "3.4.0" # change the version to the capistrano version you are using - I used capistrano version 3.3.5

set :application, "name"
#set :deploy_user, "your-ssh-deploy-user"
set :deploy_user, "user"

# setup repo details
set :repo_url, "git@bitbucket.org:user/reponame.git"
set :scm, :git

# how many old releases do we want to keep, not much
set :keep_releases, 2

这是我的产品.rb

set :stage, :production # or :staging or :your_environment
set :branch, "master" # or another branch, for example "development"

# used in case we're deploying multiple versions of the same
# app side by side. Also provides quick sanity checks when looking
# at filepaths
set :full_app_name, "#{fetch(:application)}_#{fetch(:stage)}"

#server 'your-ip-address', user: 'your-ssh-deploy-user', roles: %w{web app db}, primary: true
server 'ipaddress', user: 'myuser', roles: %w{web app db}, primary: true

set :deploy_to, "/home/dir/blah/blah"

# whether we're using ssl or not, used for building nginx
# config file
set :enable_ssl, false

#role :app, %w{deploy@your-ip-address}

#role :db,  %w{deploy@your-ip-address}
role :app, %w{myuser@myipaddress}
role :web, %w{myuser@myipaddress}
role :db,  %w{myuser@myipaddress}

Deploy user 只是普通的 capistrano 来表示适用于不同上下文的用户，例如生产、登台服务器或一般不同的服务器。我开始关注语义。
