On other platforms, the shadow file is backed up by the underlying tools used by this module. This will not be done until we delete the user from the system. In this step, we will create a new ansible playbook to deploy a new user, deploy the ssh key, and configure the ssh service. Ansible's inventory hosts file is used to list and group your servers. Next, we will generate a new ssh-key. This ansible user is permitted unrestricted sudo access but that can be restricted via the sudoers file.
It usually boils down to these three things: 1 Respect the privacy of others. This user will be automatically created by ansible, so we just need to define the username, password, and the ssh public key. Tasks for configuring the ssh will trigger the 'restart ssh' handlers. Before we create a new ansible playbook, we will scan all server fingerprint using the ssh-keyscan command as below. Drop a comment and share your experience with Ansible here. Add new user 'provision' and give the user a password.
And we need to encrypt the 'secret01' password using the mkpasswd command. In this tutorial we going to create a playbook where we will create a user for the key-based authentication and copy the public key to the remote hosts. It's a server orchestration tool that helps you to manage and control a large number of server nodes from single places called 'Control Machines'. The first step we need to do is to set up the 'control machine'. Note: If you have a lot of server nodes, you can save your host list and then manually scan the ssh key fingerprint using bash script as shown below. Is it possible with Ansible to manage this process within the user module? Testing connection to the servers ssh 10. Thanks for contributing an answer to Stack Overflow! It represents the ansible-provisioning, where the automation is defined as tasks, and all jobs like installing packages, editing files, will be done by ansible modules.
Ansible was created by Michael DeHaan in 2012 and is written in Python and Powershell. He is working with Linux Environments for more than 5 years, an Open Source enthusiast and highly motivated on Linux installation and troubleshooting. We will install python and ansible on the ansible 'control machine' by running the following command. Key management is an issue whenever access to servers must be controlled. Deploying new user and ssh-key using ansible has been completed successfully.
The ansible inventory file has been created, and our ansible scripts will be located under the 'provision' user, inside the 'ansible01' directory. Step 6 - Testing Test using ansible command. If they are not, a descriptive error message will be shown. I'm trying to re-generate ssh host keys on a handful of remote servers via ansible and ssh-keygen , but the files don't seem to be showing up. You should adjust your tasks to make them idempotent.
We will add a new user named 'provision' in order to perform server provisioning using Ansible. Posted in , Tagged , , , Post navigation. Creating User accounts Now we have a list of usernames in a variable, we can use that to create user accounts. Ansible: Post-Install Setup Inventory hosts file After you've installed Ansible, then you'll want Ansible to know which servers to connect to and manage. The improved playbook also introduces handlers and notify to restart services when the configuration changes. Now create a new ansible configuration file 'ansible.
We will also learn how to configure the Ansible 'Control Machine', as well as how to write simple ansible playbook. I need to resort to the echo -e hackery since these remotes are running Ubuntu 14. Keys must be added when new users are created, old keys must be removed when users are deleted and keys must be updated when someone forgets a pass phrase. Ansible provides that allows to do this. We could take that a step further and maintain the users via an existing Ansible module. Furthermore I'm not too sure why I'm getting it with the code because the file exist after the copy was run.
I'm going to edit it for clarification and will be more careful for my future post. By its nature, this user will need to have root privileges, and in our case, that will be achieved via sudo. Step 3 - Create New Inventory In this step, we will define the inventory files for all server hosts. Change Expire Password Account to never command: chage -E -1 ansadm - name: 3. Provide details and share your research! Now we can manage those 'ansi01' and 'ansi02' servers using Ansible, and the 'provision' user will be default user for Ansible. If this is a relative filename then it will be relative to the user's home directory.
For each server 'ansi01' and 'ansi02' , we will create a new user named 'provision' with password 'secret01'. By having the file names match to the username we can use the same users var for the loop without needing to add additional parameters at this stage. Currently learning about OpenStack and Container Technology. All tasks for deploying a new user and ssh key have been completed successfully. Install Ansible To get Ansible installed you can just run apt-get install ansible which will install version 2.
