Zugriff auf Jenkins JAR beim Start

Question

Ich baue ein Kochbuch in Chef, um einen automatisierten Dienst in Jenkins zu erstellen. Ich installiere das neueste Jenkins LTS auf CentOS, aber mir wird ständig der Zugriff auf die JAR-Datei verweigert. Hat jemand eine Lösung, um dies zu überschreiben?

Hier ist meine Ausgabe:

Answer 1

Sie müssen sicher Jenkins machen gestartet, bevor Sie die JAR-Datei herunterladen. Stellen Sie außerdem sicher, dass keine Firewall oder etwas anderes den Port blockiert.

Answer 2

Unter der Annahme, dass Jenkins nur ein bisschen länger dauert, zu starten, können Sie die Anzahl der retries erhöhen, die Chef verpflichtet sich, die Datei abzurufen:

remote_file "#{node['plugins_dir']}/jenkins-cli.jar" do 
    source node['cli_jar'] 
    retries 60 
    action :create 
    mode '0755' 
    notifies :restart, "service[#{node['repo']['name']}]", :delayed 
end 

Dies wird für 60-mal versuchen.
