Um **contêiner** roda a partir de uma **imagem de contêiner**.

Uma imagem de contêiner é uma versão **estática** de todos os arquivos, variáveis de ambiente e do comando/programa padrão que deve estar presente num contêiner. **Estática** aqui significa que a **imagem** de contêiner não está rodando, não está sendo executada, somente contém os arquivos e metadados empacotados.

* kubectl get -o jsonpath=... will now throw an error if the path is to a field not present in the json, even if the path is for a field valid for the type.  This is a change from the pre-1.5 behavior, which would return the default value for some fields even if they were not present in the json.

Un **contenedor** se ejecuta desde una **imagen de contenedor**.

Una imagen de contenedor es una versión **estática** de todos los archivos, variables de entorno y el comando/programa por defecto que debería estar presente en un contenedor. **Estático** aquí significa que la **imagen** de contenedor no se está ejecutando, no está siendo ejecutada, son solo los archivos empaquetados y los metadatos.
