Simple Jenkins pipeline file breaks in docker - docker

Question

I am running Jenkins on my OSX machine. My system was working fine last 2 weeks ago and I can't figure out what might have changed. I am running a super simple script to limit what I am doing to try to determine the problem but I am out of ideas. If anyone knows where to look next I would appreciate it.
From what I can tell the docker command is running just fine. But the pipeline is breaking possibly when it is trying to enter the running docker container??? How can I confirm this and how can I see if there is a problem with my Jenkins, Docker, or system in general.
Here is the error:

Here is my Jenkins file I got off the Jenkins website
pipeline {
agent {
docker { image 'node:7-alpine' }
}
stages {
stage('Test') {
steps {
sh 'node --version'
}
}
}
}

Check your PATH when the Jenkins pipeline does execute itself, and see if you have installed Jenkins plugins recently.
For instance, palantir/gradle-docker issue 162 mentions
I'm also experiencing this and it seems to be because the PATH environment variable running under Gradle's Exec plugin (which this plugin uses to shell out to Docker) does not include /usr/local/bin.
In my case, I installed Docker using Homebrew which placed it there.
Check also JENKINS-43294 regarding master and nodes:
I've found that you can easily work around this bug by using the pipeline plugin, and using the docker.image("some image").inside {} function.
Just place that inside the proper node('some label'){} and it will run on the desired node.
