Deploy with capistrano error: …/REVISION No such file or directory

问题

I'm using the gem Capistrano ~2.15.5 and deploying my application to my remote server. Everything works fine until the end of the cap prod deploy command. I'm receiving this error:

** [52.74.34.196 :: out] /bin/bash: ebs/apps/CloudTrendz/releases/20150318203140/REVISION: No such file or directory

  if deploy_env == 'prod'

    system "git tag -a -m 'Deployment on prod' #{tag_name}"

    system "git push origin #{tag_name}"
    if $? != 0
      raise "Pushing tag to origin failed"
    end
   end
 end

 namespace :assets do
   task :precompile, :roles => :web, :except => { :no_release => true } do
    logger.info "Skipping asset pre-compilation because there were no asset changes"
   end
 end

end

after "deploy:update", "deploy:migrate", "deploy:cleanup"

What is wrong with this code?

Thank you in advance

回答1:

It looks to me like it is failing when cloning the git repository from Github. Make sure that you've added the remote server's SSH key to the Github repository.

You can verify if this is the problem by SSH'ing into the remote server and attempting to run:

git clone git@github.com:prashant4224/CloudTrendz.git

If this fails, copy the contents of ~/.ssh/id_rsa.pub and then go to https://github.com/prashant4224/CloudTrendz/settings/keys, click "Add deploy key" and paste it in.

If ~/.ssh/id_rsa.pub does not exist on the remote server, run ssh-keygen to create it.
