Capistrano deploys not pulling latest commits - ruby-on-rails

Question

I'm deploying a Rails app with Capistrano, to an Ubuntu server (EC2).
When I deploy, with --trace, everything appears to go fine.
When I look at the revisions log on the server, it shows the latest commit hash was used on the most recent deploy, however, when I go into that latest release directory (yes I confirmed that a new release directory was created and that I'm in that one) it doesn't have the most recent commits.
If I do a 'git pull origin master' from with the new release directory on the server, of course it pulls the latest commits.
Any idea why the git pull wouldn't be happening on the Capistrano deploy?
EDIT:
Here's the deploy.rb file:
lock "~> 3.14.0"
set :pty, true
set :application, "123abc"
set :repo_url, "git#github.com:123/abc.git "
# ask :branch, `git rev-parse --abbrev-ref HEAD`.chomp
set :branch, "master"
set :rbenv_ruby, File.read('.ruby-version').strip
append :linked_files, "config/secrets.yml"
append :linked_dirs, "log", "tmp/pids", "tmp/cache", "tmp/sockets"
namespace :deploy do
before :compile_assets, :force_cleanup_assets do
on release_roles(fetch(:assets_roles)) do
within release_path do
with rails_env: fetch(:rails_env) do
execute :rake, 'assets:clobber'
end
end
end
end
app_service_name = "#{fetch(:application)}-#{fetch(:stage)}"
services = ["#{app_service_name}-workers"]
desc "Restart application"
task :restart do
on roles(:app), in: :sequence, wait: 5 do
execute :sudo, :systemctl, :stop, app_service_name
sleep 1
execute :sudo, :systemctl, :start, app_service_name
# execute :sudo, :systemctl, :restart, app_service_name
end
end
desc "Restart Workers"
task :restart_services do
on roles(:app), in: :sequence, wait: 5 do
services.each { |service| execute "sudo systemctl restart #{service}" }
end
end
desc "Start Workers"
task :start_services do
on roles(:app), in: :sequence, wait: 5 do
services.each { |service| execute "sudo systemctl start #{service}" }
end
end
desc "Stop Workers"
task :stop_services do
on roles(:app), in: :sequence, wait: 5 do
services.each { |service| execute "sudo systemctl stop #{service}" }
end
end
end

Answer 1

Is your organization using a proxy with ca certificate?.
Are you pulling from github site using SSL or from another git clone with a self signing certificate?.
Please try to su to the user used for the deployment, and attempt git pull, to see if it works?.
Are you using Tokens to authenticate or credentials or certificates?.
I would attempt to tcpdump to see what's going on, if effectively it attempts to connect to github.
Your deploy works with full clone or pull?. Can you deploy using full clone?.
Are you using SSH or HTTPS, and default or special ports?.
Can you publish the trace, or at least check that you don't have something like:
Connection refused - connect(2)
I guess that the ending spaces after your repourl are not in your final file.
Cheers

This could happen because of ownership/permissions inside <deploy_path>/repo, for example if once you had run deploy or git pull on server under other user.
Make sure that you have correct username in your deploy/<env>.rb configs and chown -r that_user:that_user <deploy_path>/repo (and may be other directories as well)
