Hello, first off thanks for resolving my issue with long running
migrations, heres what I added to the conf file to make it work:
after 'deploy:migrate', 'session:reconnect'
...
namespace :session do
desc "Force SSH to reconnect"
task :reconnect do
teardown_connections_to(sessions.keys)
end
end
-----------------------
I have another issue with long running tasks - in this case the task
is started at the end of deployment and since it is so long running I
wanted to have Cap "kick off" the task and run it in the background.
Heres what I tried:
desc "Generate Sitemap file"
task :generate, :roles => :app do
run "cd #{release_path} && nohup rake sitemap:generate
RAILS_ENV=#{rails_env}&"
end
However, no arrangement of ampersands and 'nohup' would make this
work. I did see examples online in other blogs etc. but these actually
never work.
I thought about running the actual rake task from a shell but do not
like tat solution and would simply like Cap to honor the ampersand to
run the task in the background.
Has someone been able to run a task in the background - can you show
me the exact syntax (were using Cap v. 2.5.5)?
FYI Heres what I ended up doing - its an additional set of tasks that
are run on their own command line:
cap post_deploy:jobs
---------in deploy.rb:
after 'post_deploy:jobs', 'post_deploy:sitemap:generate'
after 'post_deploy:sitemap:generate', 'session:reconnect'
...
# Put post-deploy tasks here. These are not run by the deploy task at
all
# Typically we do cap <env> post_deploy:jobs to run these (long
running) tasks
namespace :post_deploy do
desc "Run Post-Deploy Jobs"
task :jobs do
# placeholder - setup your task to be after this one
end
# generate first copy - each night at 1AM each machine also re-
generates this file
# This should not be used as it takes a long long time - and cap
doesnt make it easy or possible to run tasks in the background
namespace :sitemap do
desc "Generate Sitemap file"
task :generate, :roles => :app do
run "cd #{release_path} && rake sitemap:generate
RAILS_ENV=#{rails_env}"
end
end
end
