Capistrano deploy slow due to assets - .sprockets-manifest* - ruby-on-rails

When deploying our API (which doesn't use assets at all), it hangs for about 5 minutes on this line:
DEBUG [985661f8] cannot access /var/www/api.staging/releases/20160208111413/public/assets/.sprockets-manifest*
DEBUG [985661f8] : No such file or directory
We have already disabled assets in config/application.rb:
config.assets.enabled = false
What else needs to be done? We're using these versions:
capistrano (3.4.0)
capistrano-bundler (1.1.4)
capistrano-rails (1.1.3)
capistrano-rails-collection (0.0.3)

OK, first it is important to know that the "No such file or directory" error is benign. Capistrano executes certain commands as tests and takes different code paths based on the results, and it is completely normal that some of those tests result in failures. Unless Capistrano raises an exception, you can safely ignore these "errors".
Second, it seems that rake assets:precompile is being run even though you are not using the asset pipeline, and therefore have no use for it. I'm surprised this step could take so long if you don't have any assets, but let's leave that for another discussion.
The quick solution is to not include the asset pipeline steps of the capistrano-rails plugin. As explained in the README, you can do this by including only the steps you need.
So:
# Put these in your Capfile
require "capistrano/bundler"
require "capistrano/rails/migrations"
# REMOVE these lines so that asset pipeline steps are excluded
# require "capistrano/rails"
# require "capistrano/rails/assets"

Deploy Rails 5.1 / Webpacker app with Capistrano

I have an Ubuntu server to deploy my Rails projects. In my Ubuntu server I had RVM.
Now I want to deploy new projects with Rails 5.1 and webpacker. To deploy this projects, I've installed NVM, npm and yarn in my Ubuntu server.
In my Rails 5.1 / Webpacker project I have following gems for capistrano deployment:
Gemfile
group :development do
gem 'capistrano-rails'
gem 'capistrano-rvm'
gem 'capistrano-passenger'
gem 'capistrano-nvm', require: false
gem 'capistrano-yarn'
end
In deploy.rb I've added some configurations for capistrano nvm and capistrano yarn.
deploy.rb
set :nvm_type, :user # or :system, depends on your nvm setup
set :nvm_node, 'v7.10.0'
set :nvm_map_bins, %w{node npm yarn}
set :yarn_target_path, -> { release_path.join('client') } #
set :yarn_flags, '--production --silent --no-progress' # default
set :yarn_roles, :all # default
set :yarn_env_variables, {}
Also I've added node_modules in linked_dirs.
deploy.rb
set :linked_dirs, %w{log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system node_modules client/node_modules}
The problem comes when I execute cap deploy in assets:precompile step. Next you have the error log.

Thanks in advance!
I prefer to compile assets locally and then copy to the production servers with rsync:
# lib/capistrano/tasks/precompile.rake
namespace :assets do
desc 'Precompile assets locally and then rsync to web servers'
task :precompile do
run_locally do
with rails_env: stage_of_env do
execute :bundle, 'exec rake assets:precompile'
end
end
on roles(:web), in: :parallel do |server|
run_locally do
execute :rsync,
"-a --delete ./public/packs/ #{fetch(:user)}##{server.hostname}:#{shared_path}/public/packs/"
execute :rsync,
"-a --delete ./public/assets/ #{fetch(:user)}##{server.hostname}:#{shared_path}/public/assets/"
end
end
run_locally do
execute :rm, '-rf public/assets'
execute :rm, '-rf public/packs'
end
end
end
# config/deploy.rb
after 'deploy:updated', 'assets:precompile'
In your Capfile you need to include all the capistrano tasks:
# Load custom tasks from `lib/capistrano/tasks` if you have any defined
Dir.glob('lib/capistrano/tasks/**/*.rake').each { |r| import r }
This eliminates the need to install node and yarn on the production servers.
Of course you need node and yarn installed locally
What worked for me was making sure NVM was included in the PATH. By default, in a bash terminal, NVM adds its environment variables to the end of ~/.bashrc, but much of that file is not usually executed in a non-interactive terminal (which Capistrano runs in). I found this comment helpful:
Put your NVM source script in your .bashrc which is still evaluated even during an non-interactive SSH session. Just make sure you place the declarations at the top, before the case statement:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
# If not running interactively, don't do anything
case $- in
*i*) ;;
*) return;;
esac
The error tells you pretty much what's wrong. Neither Yarn or Node can be found on the server. Your installation might be incorrect.
Follow instructions to install both here:
https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions
and here:
https://yarnpkg.com/lang/en/docs/install/#linux-tab
Then make sure you can call:
yarn
node
On the server. If not, you might need to add paths to executables into your PATH variable
First - Install Yarn
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt update && sudo apt install yarn
Second - Install NodeJS(now 14 is newest):
curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
sudo apt-get install -y nodejs

Capistrano/Sidekiq task not working

I am using rails 4.0 and ruby 2.3.
I am using following gems for capscript.
capistrano (3.4.0)
capistrano-bundler (1.1.4)
capistrano-rails (1.1.5)
I am using capistrano/sidekiq module for running sidekiq related tasks.
When I am running
cap staging sidekiq:start
I get the following error:
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as deploy#10.50.11.190: sidekiq exit status: 1
sidekiq stdout: Nothing written
sidekiq stderr: Nothing written
SSHKit::Command::Failed: sidekiq exit status: 1
sidekiq stdout: Nothing written
sidekiq stderr: Nothing written
Below is the command which failed on running the above task.
cd /opt/optimus_apps/merchant_tracking/current && /usr/bin/env sidekiq --index 0 --pidfile /opt/optimus_apps/merchant_tracking/shared/server/tmp/pids/sidekiq-0.pid -- environment staging --logfile /opt/optimus_apps/merchant_tracking/shared/server/log/sidekiq.log --config /opt/optimus_apps/merchant_tracking/shared/server/config/sidekiq.yml --daemon
I tried running the above command directly on the staging server with a small change and it worked. I ran the following command.
cd /opt/optimus_apps/merchant_tracking/current/server && /usr/bin/env sidekiq --index 0 --pidfile /opt/optimus_apps/merchant_tracking/shared/server/tmp/pids/sidekiq-0.pid --environment staging --logfile /opt/optimus_apps/merchant_tracking/shared/server/log/sidekiq.log --config /opt/optimus_apps/merchant_tracking/shared/server/config/sidekiq.yml --daemon
I changed the rails path from
/opt/optimus_apps/merchant_tracking/current --> /opt/optimus_apps/merchant_tracking/current/server
The problem is my rails app lies inside current/server folder.
So my question is how can I make sidekiq task to pick current/server folder rather than the current folder?
Thanks in advance.

capistrano 3 `rake db:migrate` runs anyway

My rails application uses capistrano 3.4.0 for the deploy tasks.
In my Capfile I have the line require 'capistrano/rails/migrations' in order to have the configured task that can run the DB migrations.
When I cap production deploy, I can see always the following output:
INFO [deploy:migrate] Run `rake db:migrate`
DEBUG [6214167f] Running /usr/bin/env if test ! -d XXXX/releases/20160117093811; then echo "Directory does not exist 'XXXX/releases/20160117093811'" 1>&2; false; fi as deploy#candiru-web

DEBUG [1ebeb8c8] Command: cd XXXX/releases/20160117093811 && ( RAILS_ENV=production ~/.rvm/bin/rvm default do bundle exec rake db:migrate )
even if I don't add something like after :deploy, "deploy:migrate".
If I comment out the line require 'capistrano/rails/migrations', the migration won't be executed.
Why? shouldn't it run only if I add the task to my deploy script in config/deploy.rb?
According to documentation of the capistrano/rails gem, you have to set :conditionally_migrate option in order to check if you need to run migrations.
I guess that's the option you need and you should add it in your deploy.rb, this way:
set :conditionally_migrate, true
And to answer your question, in migrations.rake file the task deploy:migrate is already set to run after deploy:updated.
Also, if you want to completely remove this task from your deploy process, and always run migrations manually, by invoking deploy:migrate, you can do like this:
Rake::Task["deploy:migrate"].clear_actions

Capistrano throwing devise secret_key not set

I'm using Capistrano 3.1.4, with capfile
require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rvm'
require 'capistrano/rails'
require 'capistrano/rails/assets'
require 'capistrano/faster_assets'
require 'capistrano/rails/migrations'
I've setup my gems to use figaro and devise. When I ssh to the box, and ran (with .bash_profile export RAILS_ENV=production)
bundle install # works fine
bundle exec rake db:migrate # works fine
But when I execute:
cap production deploy:compile
I get the error stating devise secret key not set, is it because bash -login was not running on server?

Still getting gem not found with capistrano

I've been trying to configure my deployment with capistrano for a few weeks now, and it still is not working properly. Every time I deploy to my server I get an error saying a gem is missing, like:
DEBUG [a0e618f0] /home/ec2-user/.rvm/gems/ruby-2.0.0-p247/gems/bundler-1.3.5/lib/bundler/spec_set.rb:92:in `block in materialize'

I know how to fix this, simply install the "ansi" gem, but there is a much bigger problem here: why didn't bundler work properly with capistrano??

Clearly it looks like bundler was run (and successful!). What gives?
Here's my cap file:
# Load DSL and Setup Up Stages
require 'capistrano/setup'
# Includes default deployment tasks
require 'capistrano/deploy'
require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
# Loads custom tasks from `lib/capistrano/tasks' if you have any defined.
Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }
And in my production.rb (I'm deploying with production) at the top I have:
set :stage, :production
set :rails_env, "production"
Any ideas why bundler isn't working? And/ or why it never seems to install all the required gems?
Thank you a million
I've worked through similar issues with rvm involved (required rvm/capistrano) by providing some additional info to capitrano
set :bundle_cmd, '/path/to/project/rvm/bundle'
set :default_shell, :bash
set :rvm_type, :system
set :rvm_ruby_string, release_path
This code was in my stage-specific deploy (e.g., deploy/production.rb). The issue that I had to work around was that the bundle was installed but to the wrong place; could be what you're facing here as well.
FWIW, rvm/capsitrano also let me specify a shell to use when running certain commands within the deploy script. For example, I was using the whenever gem to update my crontab and needed the "rvm_shell" (my specific ruby with gemset) to make this happen from capistrano. The line looks like this:
run "cd #{release_path} && bundle exec whenever -w -s environment=production", shell: fetch(:rvm_shell)
