Zoom

Doina Cristina Duma (CNAF)

Il corso permeterà acquisire conoscenza sulle caratteristiche della cultura/paradigma DevOps; migliorare le capacità di progettare, sviluppare, distribuire e utilizzare software e servizi più rapidamente; sviluppare pratiche di automazione attraverso categorie di strumenti comuni di DevOps: source code management, continuous integration & delivery, containers, orchestrazione di containers, monitoraggio delle applicazioni, metriche e la loro visualisazione. Inoltre saranno presentati alcuni  dei strumenti a supporto dello sviluppo, resi disponibili dai Servizi Nazionali della CCR.

Gli argomenti trattati comprenderanno (in modo non esaustivo):

• Una presentazione generale del paradigma DevOps
• Nozioni base e avanzate di Git, Gitlab (baltig.infn.it)
• Gestione di progetti di sviluppo usando JIRA (issues.infn.it) e Confluence
• Containers, orchestrazione di containers, Kubernetes
• Containers Registries
• Continuous integration, definizione di pipeline per la verifica della qualità dello software, (baltig.infn.it)
• Monitoraggio, dei container e applicazioni
