É possível instalar outros componentes, como o Docker, ao criar um cluster do Dataproc
usando o
recurso
Componentes opcionais. Nesta página, você conhecerá o componente Docker.
O componente do Dataproc instala um daemon do Docker em cada nó do cluster e cria um "docker" de usuário e de grupo do Linux em cada nó para executar o daemon do Docker. Esse componente também cria um serviço "docker" systemd para executar o serviço dockerd. Você precisa usar o serviço systemd para gerenciar o ciclo de vida do serviço do Docker.
Instalar o componente
Instale o componente ao criar um cluster do Dataproc.
O componente do Docker pode ser instalado em clusters criados com a imagem versão 1.5 ou posterior do Dataproc.
Para criar um cluster do Dataproc que inclua o componente Docker, use o comando gcloud dataproc clusters createcluster-name com a sinalização --optional-components.
Além disso, ele configura o Docker para usar o Container Registry e os registros padrão do Docker.
O Docker usará o auxiliar de credenciais do Docker para fazer a autenticação com o Container Registry.
Usar o componente do Docker em um cluster do Kerberos
É possível instalar o componente opcional do Docker em um cluster que está sendo criado com a segurança do Kerberos ativada.
