Credential saving error when connecting to service on docker

Question

I am on a silicon chip Macbook Pro running macOS Monterey version 12.0.1 and the following error occurs on attempting to connect to the NGC service using sudo docker login ncvr.io.

Error saving credentials: error storing credentials - err: exit status 1, out: `Post "http://ipc/registry/credstore-updated": dial unix /var/root/Library/Containers/com.docker.docker/Data/backend.sock: connect: no such file or directory`

Answer 1

You will need to have docker running. Try opening Docker Desktop and attempt your login again.

Answer 2

i had the same issue and could resolve it by deleting the ~/.docker/config.json file. originally it contained only one entry being "credStore=desktop". after deletion, and trying to login again, it changed to "osxkeychain".

Surprisingly it worked also for me, but I don't understand why :( – Ocher

Also worked for me in macOS. – Curzon

Simply opening Docker Desktop, a newly upgraded version on my system I think, fixed the issue for me. My ~/.docker/config.json file had set "credsStore": "desktop" for what it's worth. – Biscay

Thanks. It worked for me on Docker version 4.13.0 macOs – Palladino

This can be used when you are not using docker desktop anymore. – Bosworth

Answer 3

I find that running the following (assuming you are already on the command line) helps

mv ~/.docker/config.json ~/.docker/config.json.old
cat ~/.docker/config.json.old | sed /credsStore/d > ~/.docker/config.json
rm ~/.docker/config.json.old

or, all in one go as part of my run script

mv ~/.docker/config.json ~/.docker/config.json.old; cat ~/.docker/config.json.old | sed /credsStore/d > ~/.docker/config.json; rm ~/.docker/config.json.old
