O documento descreve a configuração e o gerenciamento de um aplicativo em OpenShift, incluindo detalhes sobre a criação de builds e deploymentconfigs. Ele menciona o uso de webhooks para integração com GitHub, estratégias de build, e especificações de recursos como CPU e memória. O texto também aborda o uso de estratégias rolling e blue/green para deploy, além de parâmetros de balanceamento para rotas.
