Upload saved image to docker

Question

I've an image from another repo I'd like to upload to my docker repo.

I've managed to save it:

docker save <imageId> -o mydockersimage.tar

Now how can I upload this image to my public repo? Sorry if that's dumb, I'm getting started with docker

What do you mean by "my public repo" ? Please provide more details what you try to achieve — agg3l, Oct 21 '16 at 07:23

No, @Rao, this question is 1) about pushing to a private repo 2) an image already tagged — Guig, Oct 21 '16 at 18:56
Yes, that was to push to a private repo only. Any way, looks you got answer already. — Rao, Oct 21 '16 at 18:58

If you want to upload an image to a repository you should tag your image

docker tag [initial-image] [reponame]\[imagename]:[tag]

and then push it

docker push [reponame]\[imagename]:[tag]

If you just want to put your image to a new computer you can import this image copy the mydockersimage.tar to the new computer and do

docker import /path/to/mydockersimage.tar

But I thing it not a good practice I encourage you to do a push like my previous answer.
