Docker image commit

 

- Commit Container thành Image: Lệnh này lưu trạng thái container hiện tại thành một Image mới.
# Cú pháp: docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]
docker commit my_container my_backup_image:v1

- Save Image thành file .tar: Lưu Image vừa tạo ra file.
docker save -o backup_full.tar my_backup_image:v1 

- Cách khôi phục (Restore): Sử dụng lệnh load để nạp file tar vào Docker (nó sẽ trở thành một Image).
docker load -i backup_full.tar

- Gán Image Tag nếu không có
sudo docker image ls -a
docker tag <image_id> <name>:latest
