Adding hosts to CML Ubuntu server /etc/hosts file

[ramirezcyrus]

The /etc/hosts file is a readonly file. Is there any way I can create another hosts file to add devices to in order to complete an ansible lab?

Hello @ramirezcyrus ,

If your user is a member of the sudo group, which should be true for a CML Ubuntu server, you can edit the file /etc/hosts using the sudo command:

sudo nano /etc/hosts

or

sudo vi /etc/hosts

The OS will ask you again for your password and after you supply it, you can edit the file in the editor of your choice.

By default, Ansible uses the inventory file located in /etc/ansible/hosts

You can use any inventory file you want, but in this case you have to provide the path to the inventory file with the -i parameter when running Ansible commands.

It's better to use the default ansible inventory file in /etc/ansible/hosts and leave the /etc/hosts for it's intended purpose of name resolution.
