Docker Container 옮기기#

1. 백업전 Container 종료 (Stop container)
2. Container Image로 저장 (Save container)
3. 새로운 Image 확인 (Check container)
4. Tar파일로 Export (Export image)
5. Tar파일로부터 Docker Image 만들기 (Load image)
6. Image로부터 Container 생성하기 (Create container)

1. 백업전 Container 종료 (Stop container)#

$ docker stop curr_20200812
curr_20200812

$ 

2. Container Image로 저장 (Save container)#

• curr_20200812 (ContainerName) = 02e4cbbb6083 (ContainerID)
• docker commit -p {ContainerID} {NewImageName}

$ docker commit -p 02e4cbbb6083 new_20230125
sha256:800ec1b622c0beb81fdebc7a5b6bc83d2c9906dba66a6c4885307b819520f528

$ 

3. 새로운 Image 확인 (Check container)#

$ docker images
REPOSITORY             TAG                 IMAGE ID            CREATED             SIZE
curr_20200812         latest              ed24abf0dc3c        9 months ago        1.4GB
new_20230125          latest              800ec1b622c0        4 minutes ago       2.06GB

$ 

4. Tar파일로 Export (Export image)#

$ docker save -o ./new_20230125.tar new_20230125

$ ls
-rw-------   1 ssem  staff   1.9G  5 24 14:49 new_20230125.tar

$ 

5. Tar파일로부터 Docker Image 만들기 (Load image)#

• 4에서 만들어지 tar파일을 Target 시스템으로 복사한 후 load 시켜준다.

• docker load < [백업한 파일이름].tar

• docker load -i [백업한 파일이름].tar

$ docker load -i new_20230125.tar
