Add capability to authenticate with docker account when pulling images

[thewookiewon]

Would it be possible to add an option to pass an API token to allow authenticated docker pulls?

Basically getting the below error

You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit

How/where would you need the API-token? Like how is it used?

My understanding is that all you've got to do is to first login with docker login --username=yourUsername and then start pulling. But I might be wrong or maybe misunderstood the issue, have not needed to troubleshoot this myself.

(link to docker-commandline-login docs )

I would need some more info to be able to continue on this, know the actual issue / preferred outcome.

Yes I can just do that docker login --username=yourUsername

Maybe I was just looking for that capability to be added to the app BUT happy if you prefer to close this FR.

You could create yourself a function in your .bashrc or so.

Something like

function dchk {
  docker login --username YourUser
  /home/user/dockcheck.sh "$@"
}

Then you can run eg. dchk -yp -e nginx or whatever flags/arguments needed and it would first prompt your login.

Or if you'd like to not have to write the password, but read it from a file:

function dchk {
cat ~/pwd.txt | docker login --username YourUser --password-stdin
~/dockcheck.sh "$@"
}

Edit as necessary (paths, usernames etc).

Added this suggestion to the Readme, wont implement it to the actual script - closing.
