Login failure into ACR with helm 3.7 / 3.8

Question

Hi,

I am getting error: Error: Get "https://myregistry.azurecr.io/v2/": unauthorized: authentication required, visit https://aka.ms/acr/authorization for more information. when login a service principal with helm:

echo $SP_PASSWD | helm registry login myregistry.azurecr.io --username $SP_ACR_ID --password-stdin

On the other hand docker succeeds:

echo $SP_PASSWORD | docker login myregistry.azurecr.io --username $SP_ACR_ID --password-stdin
Login Succeeded

Can you suggest best way to resolve this? This is blocking azure pipeline builds.

Thanks!
MT

Hi @MT ,
Thanks for reaching out to Microsoft QnA Platform. Apologies for he delay in response.
From the above commands posted by you, I can see the password is stored in two different variables for both the commands, one is $SP_PASSWD, and the other one is $SP_PASSWORD. Could you please check and verify if you are providing the the variable name correctly.

Also, I checked and the helm registry login works fine. Please see the below output.

~$ echo -n "$password" | helm registry login $registry -u $username --password-stdin  
Login Succeeded  
~$ helm version  
version.BuildInfo{Version:"v3.8.0", GitCommit:"d14138609b01886f544b2025f5000351c9eb092e", GitTreeState:"clean", GoVersion:"go1.17.5"  

Please let me know if the issue is still persisting and if the my above response helps.
