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.tar
108M nginx.tar

$ docker save php:5-apache > php.tar.gz
$ ls -sh php.tar.gz
372M php.tar.gz

$ docker save --output nginx.tar nginx
$ ls -sh nginx.tar
108M nginx.tar

$ docker save -o nginx-all.tar nginx
$ docker save -o nginx-latest.tar nginx:latest
