How do I download Docker images without using the pull command?

Question

Is there a way I can download a Docker image/container using, for example, Firefox and not using the built-in docker-pull.

I am blocked by the company firewall and proxy, and I can't get a hole through it.

My problem is that I cannot use Docker to get images, that is, Docker save/pull and other Docker supplied functions since it is blocked by a firewall.

Answer 1

Just an alternative - This is what I did in my organization for couchbase image where I was blocked by a proxy.

On my personal laptop (OS X)

~$ $ docker save couchbase > couchbase.tar
~$ ls -lh couchbase.docker
-rw-------  1 vikas  devops   556M 12 Dec 21:15 couchbase.tar
~$ xz -9 couchbase.tar
~$ ls -lh couchbase.tar.xz
-rw-r--r--  1 vikas  staff   123M 12 Dec 22:17 couchbase.tar.xz

Then, I uploaded the compressed tar ball to Dropbox and downloaded on my work machine. For some reason Dropbox was open :)

On my work laptop (CentOS 7)

$ docker load < couchbase.tar.xz
