Hi, i’m still learning how to use docker and I followed this guide which combines jenkins and docker to deploy a simple application. (https://www.docker.com/sites/default/files/RA_CI%20with%20Docker_08.25.2015.pdf)
I followed all the steps, but when i try to “docker push dtr.mikegcoleman.com/hello-jenkins:$GIT_COMMIT” I need authentication and the job fails.
I tried docker login localhost:8080 with user: "root" and password: “rootpw”. But cant login.
Using Centos 7.1
