Can not get Edge to listen to localhost 0.0.0.0 on co-located headless vm

Technical Question

Hi,

I am following the docs to attempt to get Edge and Stream running on a single host. Steam deploys and listens on 0.0.0.0:9000 but Edge will only listen on 127.0.0.1:9420. This is a headless VM so I can not get to the GUI locally to continue following the docs process.

ubuntu@cribl:/opt/cribl-edge/default/cribl$ netstat -nlp

Any suggestions please or do I have to put nginx on as a proxy to get both sites working?

Hi @kane.kennedy, you can set the CRIBL_EDGE environment variable to any value to bind to 0.0.0.0 instead of the 127.0.0.1 address.

Or when you start the Cribl Edge from the CLI, ensure you pass in the -H 0.0.0.0 parameter.

Something else to note… if you connect your Edge node to a leader, it will automatically update the binding IP address to the one configured in the Fleet Settings. You will need to change this to 0.0.0.0 if you want the Edge Node to always listen on all IP addresses.

@bdalpe Thank you,

The env variable on it’s own didn’t solve the issue but it did in combination with swapping to mode-edge, starting and stopping Cribl.

I thing the docs on Installing Cribl Edge on Linux | Cribl Docs are incorrect and should tell you to deploy as mode-edge not mode-managed-edge.

Upwards and onwards into getting data in and out next.

Thanks again

Kane.

In the single instance section the docs rightly specify readers to use mode-edge. In the section following that the docs state to use mode-managed-edge given the assumption that you’d want your Edge nodes to be communicating with your leader node just like your existing worker nodes. The mode is predicated on whether you want it to be managed from the leader node, not whether it’s going to be on the same host as Stream.
