Error deploying rails app with Kamal: Docker login fails with exit status 256

I'm trying to deploy the rails app using Kamal, but the deployment fails during the docker login step with the following error:

    ERROR (SSHKit::Command::Failed): docker exit status: 256  
docker stdout: Nothing written  
docker stderr: WARNING! Using --password via the CLI is insecure. Use --password-stdin.

# Grab the registry password from ENV

GOOGLE_API=$GOOGLE_API
PIXABAY=$PIXABAY
OPEN_WEATHER=$OPEN_WEATHER
POSTGRES_PASSWORD=$POSTGRES_PASSWORD
POSTGRES_USER=$POSTGRES_USER

# Improve security by using a password manager. Never check config/master.key into git!
RAILS_MASTER_KEY=$(cat config/master.key)

How can I resolve this error during Kamal deployment? Any help would be greatly appreciated

Solution

  • I found the answer from this link Since I'm using wsl2 ubuntu

    I navigated to the Ubuntu terminal using the following command

    ibunhabibu@DESKTOP-RG3E4I0:/mnt/c/Users/projects/rails/writehub$ cd ~
ibunhabibu@DESKTOP-RG3E4I0:~$ cd .docker/
ibunhabibu@DESKTOP-RG3E4I0:~/.docker$ nano config.json

    then I edited it from

    {
  "credsStore": "desktop.exe"
}

    to

    {
  "credStore": "desktop.exe"
}

    after removing s in credsStore the problems solved
