systemd integration

[dimidd]

Hi, I'd like to restart shoryuken after a restart and after a deploy (preferably with capistrano-shoryuken). Is there an equivalent for the sidekiq systemd unit file?

Hi @dimidd

There's not. But I guess it's just a matter of s/sidekiq/shoryuken/g in the systemd unit file you linked.

Besides the search and replace, you may need to change this line as well, for something like ExecStart=/usr/local/bin/bundle exec shoryuken -C /path/shoryuken.yml ....

Please let me know if you create a system unit file, so I can update this wiki with the instructions.

Thanks, I'm using this one, which seems to work, but I still have to test it thoroughly.

@dimidd nice! I linked your gist in here.

FYI
foreman will export Procfile to systemd for You!
I used foreman 0.84.0 out of the box
I added to my capistrano deploy.rb some lines:

namespace :foreman do
  desc "Export the Procfile to Ubuntu's systemd scripts"
  task :export do
    on roles(:app) do
      within release_path do
        with rails_env: fetch(:stage) do
          execute :sudo, '/home/boss/.rvm/bin/rvm 2.4.2 do bundle exec foreman export systemd /etc/systemd/system ' +
        "-f Procfile.#{fetch(:stage)} -a #{fetch(:application)}-#{fetch(:stage)} -u #{fetch(:user)} -l #{shared_path}/log -e #{shared_path}/.env --root #{current_path}"
        end
      end
    end
  end
end

Where #{shared_path}/.env have entries with standard KEY=value syntax

Content of Procfile.staging

web: /home/boss/.rvm/bin/rvm 2.4.2 do bundle exec unicorn -c ./config/unicorn.rb
worker: /home/boss/.rvm/bin/rvm 2.4.2 do bundle exec shoryuken --rails -C config/shoryuken.yml

This command will create all files for systemd:

cap staging foreman:export

What we have in the sytemd

ls -1 /etc/systemd/system/boss*
/etc/systemd/system/boss-staging.target
/etc/systemd/system/boss-staging-web@.service
/etc/systemd/system/boss-staging-web.target
/etc/systemd/system/boss-staging-worker@.service
/etc/systemd/system/boss-staging-worker.target

/etc/systemd/system/boss-staging-web.target.wants:
boss-staging-web@3010.service

/etc/systemd/system/boss-staging-worker.target.wants:
boss-staging-worker@3110.service
