I'm quite not sure that this post could be useful for someone else because the other day I faced a weird situation to install docker-cli and docker images to an EC2 instance of AmazonLinux2023 which is isolated from the Internet by the VPC policy in my company.
My plan was that docker-cli and docker images were downloaded with my private PC, those binaries split were uploaded to S3, those were downloaded them in in-house PC, and finally those were transferred to the EC2 instance.
First of all, I didn't know which an architecture of this AmazonLinux2023 was used, then I found x86_64(amd64) by this command. Also I found it was composed of Fedora 34.
uname -a
The official docker document said you can find docker-cli images as follows Index of linux/fedora/34/x86_64/stable/Packages/. But resolving the dependencies libraries was found. So you should not follow that official instruction.
To download docker-cli, these commands worked after creating /bin in the current directory. In Fedora lately, you need to use dnf instead of yum, btw.
docker run --rm -v {$PWD}/bin:/tmp -it amazonlinux:2023 bash
cd /tmp
dnf install 'dnf-command(config-manager)'
dnf install --downloadonly --downloaddir=/tmp docker

You would see many rpms in /bin.
Now I was ready to download docker images. This was easier part. Only you execute is to docker pull, docker save and docker load. The last two commands I didn't know earlier are quite useful to save a docker image. Say
docker pull --platform linux/amd64 python:slim
docker save python:slim > image.tar
Next I needed to upload the image to S3 after split.
split -b 10M -d image.tar split-
Those tiny images could be downloaded through the proxy of my company. After collecting those scattered files, I merged them by
cat split-?? > image.tar
After scp, you need to install docker-cli. Also you need to take care of the installing order because many rpms have the order of dependencies.
After installing docker-cli, you can docker load and you'll get docker images finally.
docker load < image.tar
