unable to resolve host n1: Name or service not known

[Mariyam Mapkar]

Hello all,

I recently created a slice in FABRIC and I was able to reserve it. However, when I try to install docker I am getting error; unable to resolve host n1

n1 is the name of my node

I tried resolving this issue several times but was unable to do so. can anybody provide me guidance on resolving this issue?

I am attaching screenshots of my error as well

Thanks

Here is what I’ve been doing after the slice has been set up. I’m not really sure if there is a better way to fix this:

 

command = ‘echo “127.0.0.1 $HOSTNAME” | sudo tee -a /etc/hosts’

node1 = slice.get_node(name=node1_name)
stdout, stderr = node1.execute(command)

Also we do provide images with Docker pre-configured. There is a notebook in the examples that shows how to list available images, the docker ones are easy to tell apart since they have the word docker in them.
