我在一个阶段将 Capistrano v3 中的配置实施到多台服务器时遇到问题。或者我想要一些不可能的东西。
我在 deploy.rb 中创建了一个测试任务,如下所示:
namespace :test do
task :run do
on roles(:all) do
print "\nenvcode:\n"
p fetch(:envcode)
print "\nglobal_var:\n"
p fetch(:global_var)
print "\nssh_options:\n"
p fetch(:ssh_options)
print "\nmain_domain_name:\n"
p fetch(:main_domain_name)
end
end
end
这是一个在同一阶段定义为模拟服务器的配置:
role :app, %w{ip1 ip2}
role :web, %w{ip1 ip2}
role :db, %w{ip1 ip2}
set :main_domain_name, "#{fetch(:envcode)}.mytestdomain.com"
set :global_var, 'foobar'
set :ssh_options, -> do
{
user: 'userip0'
}
end
server 'ip1',
roles: %w{web db app},
ssh_options: { user: 'userip1' },
user: 'userip1',
envcode: "envip1",
dbname: 'userip1',
dbuser: 'userip1',
dbpass: 'password',
dbhost: 'localhost'
server 'ip2',
roles: %w{web db app},
ssh_options: { user: 'userip2' },
user: 'userip2',
envcode: "envip2",
dbname: 'userip2',
dbuser: 'userip2',
dbpass: 'password',
dbhost: 'localhost'
当我运行 cap staging test:run 我得到这个输出意味着 capistrano 完全忽略了我的服务器覆盖:
envcode:
nil
global_var:
"foobar"
ssh_options:
{:user=>"userip0"}
envcode:
nil
main_domain_name:
".mytestdomain.com"
global_var:
"foobar"
ssh_options:
{:user=>"userip0"}
main_domain_name:
".mytestdomain.com"
我希望得到:
envcode:
envip1
global_var:
"foobar"
ssh_options:
{:user=>"userip1"}
envcode:
envip2
main_domain_name:
"envip1.mytestdomain.com"
global_var:
"foobar"
ssh_options:
{:user=>"userip2"}
main_domain_name:
"envip2.mytestdomain.com"
我做错了什么,还是我对这些服务器配置阵列的理解有误?
