Visão Geral

Docker é uma plataforma para desenvolvedores e administradores de sistemas manterem aplicativos distribuídos. Consiste em um tempo de execução para executar contêineres e um serviço para compartilhar contêineres.

Com o docker, o mesmo aplicativo pode ser executado inalterado em laptops, servidores dedicados e servidores virtuais.

Este curso, durante os dois primeiros dias, ensina o uso básico do Docker, útil tanto para desenvolvedores quanto para administradores de sistema. O curso inclui muitos exercícios práticos e os participantes praticarão em seu próprio ambiente Docker e construirão suas próprias imagens Docker.

No último dia, os participantes aprenderão sobre ferramentas mais avançadas que oferecem suporte ao Docker. Será Docker Machine, Docker Compose e Docker Swarm.

Pre-Requisitos

• Familiaridade com linha de comando e Linux
