How Do I Create an Image Package?
Run the docker save command to compress the container image into a .tar or .tar.gz package. The command format is as follows:
docker save [OPTIONS] IMAGE [IMAGE...]
[OPTIONS] can be set to --output or -o, indicating that the image is exported to a file.
Example:
$ docker save nginx:latest > nginx.tar$ ls -sh nginx.tar108M nginx.tar$ docker save php:5-apache > php.tar.gz$ ls -sh php.tar.gz372M php.tar.gz$ docker save --output nginx.tar nginx$ ls -sh nginx.tar108M nginx.tar$ docker save -o nginx-all.tar nginx$ docker save -o nginx-latest.tar nginx:latest
