Nos meus estudos tive uma duvida que foi sanada na mesma aula do treinamento DescomplicandoKubernetes ...
Pessoal, quando estava fazendo a aula (Fazendo Rollback e conhecendo o comando Rollout) no minuto 2:40 o @badtuxx fez o rollback do deployment (kubectl rollout undo deployment -n giropops nginx-deployment) para voltar para o deploy anterior.
No primeiro momento eu pensei que o "rollout undo" faria o rollback do "Deploy Inteiro", porem no minuto 4:02, ao fazer o describe mostrou que as alterações feitas nas informações do Deploy ( como as Labels e as Replicas) permaneceram.
No minuto 6:17 que eu entendi que na verdade o rollout cuida somente das configurações a nivel de Pod.
Achei valido trazer essa informação porque me foi muito importante.
na Documentação está sendo falado dobre isso... atente a Nota:
