Pull access denied docker hub

Im triying to pull docker image of jboss/wildlfy:14.0.1.Final from docker hub, a few days ago I use this image without problems, but now Im getting this error:

  • docker: Error response from daemon: pull access denied for jboss/wildlfy, repository does not exist or may require ‘docker login’: denied: requested access to the resource

I understand that is a login problem, but ¿Why now I required Login to pull the imagen?

The most popular way of deploying an application is using the deployment scanner. In WildFly this method is enabled by default and the only thing you need to do is to place your application inside of the deployments/ directory. It can be /opt/jboss/wildfly/standalone/deployments/ or /opt/jboss/wildfly/domain/deployments/ depending on which mode you choose (standalone is default in the jboss/wildfly image)
