docker rmi <image-id>
docker rmi -f <image-id>
# docker rmi 3f5b9885f749
Excluir imagem com tag específica

docker save -o db.tar e0d9768dfdbf
## load saved image(compressed file) in to docker
docker load -i <saved file>
docker load -i db.tar
Trabalhando com contêineres
Iniciar contêiner
docker start <container-id>
Parar o recipiente
docker stop <container-id>
Reiniciar contêiner
docker restart <container-id>
Listar contêineres em execução
docker ps
Listar todos os contêineres (em execução + interrompido)
docker ps -a
Registros de contêineres
docker logs <container-id>
Detalhes de configuração do contêiner
docker inspect <container-id>
Faça login / conecte-se ao contêiner
docker exec -it <container-id> bash
# example
docker exec -it adea7b2dbc98 bash
Excluir contêiner
docker rm <container-id>
docker rm -f <container-id>
Excluir todos os contêineres
docker rm $(docker ps -a -q)
