Capistrano - Like that person you hate, yet end up falling in love with

Started by dennmart · 8 months ago

One of the reasons I went exploring into Rails was because of Capistrano, a utility that greatly helps deploying Rails sites into production servers, by automating many of the tedious setup steps needed to deploy new changes into production.

    Great write-up. I found the information regarding the the missing 'script/spin' file helpful. Thanks ;)

    Nice writeup. Regarding spin, I find it useful to add a task to create it rather than have it in svn.



    namespace :deploy do
    namespace :spinner do
    desc :app do
    dispatcher_type = fetch(:dispatcher_type, 'mongrel')
    dispatcher_instances = fetch(:dispatcher_instances, 3)
    dispatcher_bind_ip = fetch(:dispatcher_bind_ip, '127.0.0.1')
    dispatcher_starting_port = fetch(:dispatcher_starting_port, 8000)
    rails_env = fetch(:rails_env, 'production')

    script = 0755
    end
    end
    end


    Then, use a trigger to execute it:


    after "deploy:update_code", "deploy:spinner:write"


    Note, this is for cap 2.x.

    The code above did not come out well. Let's try that again.


    namespace :spinner do
    desc :app do
    dispatcher_type = fetch(:dispatcher_type, 'mongrel')
    dispatcher_instances = fetch(:dispatcher_instances, 3)
    dispatcher_bind_ip = fetch(:dispatcher_bind_ip, '127.0.0.1')
    dispatcher_starting_port = fetch(:dispatcher_starting_port, 8000)
    rails_env = fetch(:rails_env, 'production')

    script = 0755
    end
    end

    Hi Dave,

    Thanks for that snippet. It does sound better having Capistrano take care of the spinner script rather than keeping it in the repository. I'm sure I'll find it very valuable when deploying my upcoming project. Thanks!

    Hello ,

    My previous seminar went well. Now I have an another query, if you help me in this also.
    As there is a concept of remoting in .net,
    is this possible to deploy the components in ROR and to make these components communicate with each other as done in remoting concept?
    Is this possible in ROR?
    Please guide me.

    Thanks
    Harbans
