SSH fail during node_exporter installation

[lykholat]

Hello the node exporter installation is failing during this part:
TASK [prometheus.prometheus.node_exporter : Download node_exporter binary to local folder] ************************
fatal: [...*]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: ubuntu@localhost: Permission denied (publickey).", "unreachable": true}

I tried this line and no errors were obtained but the installation ended up being moved to the provisioning machine and not in the target:
ansible-playbook nodeexp.yml -i inventory --connection=local

I'm using the simplest example of playbook and all the other tasks executed fine

• hosts: targets
  become: true
  roles:
  • prometheus.prometheus.node_exporter

Issue solved by modifying the install.yml file. I removed all lines that say "delegate_to: localhost"

Do you have the hostname "localhost" in your ansible inventory? Ansible should default to a local connection and not ssh for localhost.

Passing --connection=local to ansible-playbook is not ideal as it will attempt to use the local connection for all of the targets.
instead, you could do something like this in your inventory:

localhost ansible_connection=local

Also ran into this and rolled back to 0.5.1 for now. I don't have any localhost in inventory as far as I can see
Maybe we could have a PR to add connection: local to those steps?

I'm having the same issue, with the following inventory:

server:
  hosts:
    server.example.com:
  children:
    gitea:
    nextcloud:
    transmission:
    status:

other:
  hosts:
    localhost:

localhost:
  ansible_connection: local

# What --------------------

status:
  hosts:
    status.example.com:
