I wrote this task to prompt for a git branch or tag to deploy. I'm pretty
new to RoR and Capistrano so I'd welcome any critique. And, maybe this will
be useful for others.
I have this at the end of my Capfile:
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }
I put this in file lib/capistrano/tasks/git_tasks.rake
desc "Prompt for branch or tag"
task git_branch_or_tag: :'git:wrapper' do
on roles(:all) do |host|
tags = "<none>"
within repo_path do
with fetch(:git_environmental_variables) do
tags = capture(:git, :tag).split.join(', ')
end
end
run_locally do
tag_prompt = "Enter a branch or tag name to deploy, available tags
include #{tags}"
ask(:branch_or_tag, tag_prompt)
tag_branch_target = fetch(:branch_or_tag)
execute "echo \"About to deploy branch or tag
'#{tag_branch_target}'\""
set(:branch, tag_branch_target)
end
end
end
before 'deploy:starting', :git_branch_or_tag
