Hi all,
I wish to specify an app server as "spare" - to be out of the load
balancer rotation. I specified as so:
role :app, '192.168.10.99', :spare => true # machines out of load
balancer rotation
The task is like this:
namespace :loadbalancer do
desc 'Remove "spare" machines from load balancer rotation by
removing public/healthcheck/balancer (to be run just before
apache:reload)'
task :set, :roles => :app, :only => { :spare => true } do
run("rm -f #{release_path}/public/healthcheck/balancer")
end
end
----------------------
The problem is that in some environments (we use what I think is
called multistage) there is no spare machine (i..e, staging) and so I
would configure no machine as designated as spare:
role :app, '192.168.10.99'
When I do this I see this error:
`deploy:loadbalancer:set' is only run for servers matching
{:roles=>:app, :only=>{:spare=>true}}, but no servers matched
----------------------
So, I designated a "blank" machine as spare:
role :app, '', :spare => true # NO machines out of load balancer
rotation
When I run the task, I know see this command being run:
servers: ["192.168.10.90", ""]
followed by an error indiocating it could not ssh into machine due to
an authentication error.
In other words, cap is trying to shh into a blank IP address.
--------------------
Seems like there should be a way to have 'spare' specified in some
configs and not in others - any one know how?
Mike
