我有多阶段多服务器设置,在我的任务中我需要使用服务器名称,例如在stagin.rb我有:
set :stage, :staging
# Define servers
server 'xxx.xx.xx.xxx', user: 'deploy', roles: %w{app}, name: 'app1'
server 'xxx.xx.xx.yyy', user: 'deploy', roles: %w{app}, name: 'app2'
我想在我的任务中使用"name"变量:
task :configure do
on roles(:app), in: :parallel do
# how do I get server name here?
end
end
我正在尝试使用capistrano(第一次)部署我的rails应用程序.首先要点,我正在使用:
尝试运行时出现以下错误 cap production deploy

我正在使用capistrano:Capistrano版本:3.6.1(耙子版本:11.3.0)

在此之前3.0有一种方法可以做到这一点:
# ...
set :mysql_password, proc { Capistrano::CLI.password_prompt "Gimme remote database server password. Don't worry, I won't tell anyone: " }
# ...
namespace :db do
desc 'Dump remote database'
task :dump do
run "mysqldump -u #{mysql_user} -p #{mysql_database} > ~/#{mysql_database}.sql" do |channel, stream, data|
if data =~ /^Enter password:/
channel.send_data "#{mysql_password}\n"
end
end
end
end
它提示输入密码,在您键入时不显示密码,并且在日志和输出中不留下任何痕迹.
现在,作为3.0我发现的唯一方式:
# ...
namespace :db do
desc 'Dump remote database'
task :dump do
ask :mysql_password, nil
on roles(:db) do …我在命名空间中有一个命名空间和几个任务,在deploy:updated之后运行.这是一个例子:
namespace :myservice do
task :start do
on roles(:app) do
sudo :start, "my/application"
end
end
end
我喜欢这些任务中的一个只能在特定环境或主机属性上运行.我怎么能做到这一点？
我希望能够过滤环境,例如:
namespace :myservice do
task :start do
on roles(:app), env(:vagrant) do
sudo :start, "my/application"
end
end
end
完成此任务的最佳方法是什么？
在Capistrano 2中,你可以这样做:
set :default_environment, {
'PATH' => '$PATH:/opt/rubies/ruby-2.1.1/bin'
}
是否有上限3的等价物？
我有以下capistrano 3任务:
desc 'Add root scheduled tasks'
task :root_schedules do
on roles(:all) do
within release_path do
execute :sudo, :bundle, 'exec whenever -w config/root_schedule.rb -u root'
end
end
end
我需要使用sudo权限运行此任务,因为我需要以更高权限运行计划任务.这些是后端计划的服务器任务.问题是我每次运行此命令时都会得到以下信息:
DEBUG [46d3800c] [sudo] password for [user]
输入密码后按Enter键,它永远不会完成任何操作.完全没有回应.有答案吗？

我一直在努力让基本的 Capistrano 部署在我的登台服务器上工作。我按照本指南设置了 Capistrano。
git:check由于据称无权访问我在 GitLab上的存储库，部署过程总是在舞台上失败。我确信我的 SSH 代理转发工作正常，因为我能够通过 SSH 连接到我的服务器并使用我的 SSH 密钥访问 GitLab。SSH 密钥未存储在我服务器上的任何位置：
$ ssh deploy@myserver.com
deploy@MyServer:~$ ssh -T git@gitlab.com
debug1: client_input_channel_open: ctype auth-agent@openssh.com rchan 2 win 65536 max 16384
debug1: channel 1: new [authentication agent connection]
debug1: confirm auth-agent@openssh.com
Welcome to GitLab, Alexander!debug1: channel 1: FORCE input drain
到目前为止，关于这个问题的所有问题都没有对我有用。
这是我的部署文件：
部署文件
set :application, "myapp"
set :branch, "master"
set :repo_url, "git@gitlab.com:MyApp/myapp.git"
