Quando o **contêiner** é iniciado e está rodando (iniciado a partir de uma **imagem de contêiner**), ele pode criar ou modificar arquivos, variáveis de ambiente, etc. Essas mudanças vão existir somente nesse contêiner, mas não persistirão na imagem subjacente do container (não serão salvas no disco).

/// tip

Don't worry if some of these items about **containers**, Docker, or Kubernetes don't make a lot of sense yet.

/// tip | "Tipp"

Machen Sie sich keine Sorgen, wenn einige dieser Punkte zu **Containern**, Docker oder Kubernetes noch nicht viel Sinn ergeben.

Ich werde Ihnen in einem zukünftigen Kapitel mehr über Container-Images, Docker, Kubernetes, usw. erzählen: [FastAPI in Containern – Docker](docker.md){.internal-link target=_blank}.

### Ephemeral Containers Graduate to Stable

#   TF uses hub.docker.com/r/tensorflow/build containers for CI,
#   and scripts on Linux create a persistent container called "tf"
#   which mounts your TensorFlow directory into the container.
#
#   Important: because the container is persistent, you cannot change TFCI
#   variables in between script executions. To forcibly remove the
#   container and start fresh, run "docker rm -f tf". Removing the container

  - Changed the Pod API so that the `resources` defined for containers are mutable for `cpu` and `memory` resource types.
  - Added `resizePolicy` for containers in a pod to allow users control over how their containers are resized.
  - Added `allocatedResources` field to container status in pod status that describes the node resources allocated to a pod.
  - Added `resources` field to container status that reports actual resources applied to running containers.
