Elastic Search stops on my VPS mainly after a deploy

Hi,

I have a small VPS running my Rails app which is a personal website. I use SearchKick and that in turn uses ElasticSearch.

I find that ElasticSearch appears to fall over. I notice it mainly after a deploy. I had a similar issue with Delayed Job and was told I could set up a Capistrano task to restart that after each deploy. Code for that is below. That works fine but I don’t think I can do the same for ElasticSearch (I have tried and it didn’t work).

Anyone have any ideas as to how I can ensure ES is running properly after a deploy?

The code to restart Delayed Job is:

namespace :delayed_job do
 
    def args
      fetch(:delayed_job_args, "")
    end
   
    def delayed_job_roles
      fetch(:delayed_job_server_role, :app)
    end
   
    desc 'Stop the delayed_job process'
    task :stop do
      on roles(delayed_job_roles) do
        within release_path do
          with rails_env: fetch(:rails_env) do
            execute :bundle, :exec, :'bin/delayed_job', :stop
          end
        end
      end
    end
   
    desc 'Start the delayed_job process'
    task :start do
      on roles(delayed_job_roles) do
        within release_path do
          with rails_env: fetch(:rails_env) do
            execute :bundle, :exec, :'bin/delayed_job', args, :start
          end
        end
      end
    end
   
    desc 'Restart the delayed_job process'
    task :restart do
      on roles(delayed_job_roles) do
        within release_path do
          with rails_env: fetch(:rails_env) do
            execute :bundle, :exec, :'bin/delayed_job', args, :restart
          end
        end
      end
    end
   
  end
