Docker login auth token

Question

I'm trying to get docker login auth from ~/.docker/config.json file. But I can't see auth token in my config.json file. Here is my docker version.

docker version Client:  Version:      17.03.1-ce  API version:  1.27  Go version:   go1.7.5  Git commit:   c6d412e  Built:        Tue Mar 28 00:40:02 2017  OS/Arch:      darwin/amd64  Server:  Version:      17.03.1-ce  API version:  1.27 (minimum version 1.12)  Go version:   go1.7.5  Git commit:   c6d412e  Built:        Fri Mar 24 00:00:50 2017  OS/Arch:      linux/amd64  Experimental: true 

When I run cat ~/.docker/config.json then what I can see is

cat .docker/config.json {     "auths": {         "https://index.docker.io/v1/": {}     },     "credsStore": "osxkeychain" }% 

According to Codeship documentation I should have to see

{     "auths": {         "https://index.docker.io/v1/": {             "auth": "auth_key",             "email": "email"         }     } } 

Can I disable storing my authkey in keychain?

I really need to get auth_key, how can I get that?

Thank you

Answer 1

Auth is simply a base64 encoded 'username:password' string. You can get it with the following command:

echo -n 'username:password' | base64 

Answer 2

If you are using Kubernetes, and you need it for creating the registry password just run:

kubectl create secret docker-registry --dry-run=true docker-regcred \ --docker-server=https://index.docker.io/v1/ \ --docker-username=xxx \ --docker-password=xxx \ [email protected] \ --namespace=xxx \ -o yaml > docker-secret.yaml 

This will create docker-secret.yaml with your JSON there. if you dont include --dry-run=client and -o yaml > docker-secret.yaml It will create the k8s secret.
