Note: whatever changes we did in the host file, it will start being considered.ģ.Now create one user(ex:insight) in all servers/instances/machines. # some basic default values… inventory = /etc/ansible/hosts sudo_user = root >Uncomment # inventory = /etc/ansible/hosts ….# some basic default values… # inventory = /etc/ansible/hosts # sudo_user = root >Now this host file is only working after updating the “ansible.cfg” file. # Ex 1: Ungrouped hosts, specify before any group headers.Ĭhecks nodes are integrated, >cat /etc/ansible/hosts >Now go to the hosts file of the ansible server and paste Private_IPs of all integrated nodes/servers.Ĭreate a group and add the nodes.(For example group means Prod or Dev Cluster) # yum install git python python-level python-pip openssl ansible -yĢ.Integrating all hosts/nodes/servers(Slave) with Ansible server(Master) Now, we have to install all the packages one by one(Some dependencies software) Ansible does not need any special skills to install and use it.ġ.Now go to the inside ansible server and download the ansible package. It is very secure due to its agentless(no chef client), capabilities and open SSH security features.ĩ. Ansible is a Python-dependent configuration-management software, where both the controlling node and the target machine must have Python and its dependent packages installed.Ĩ. RedHat launches the Ansible Tower (GUI).ĥ. YAML language is a simple text human-readable file.Ĥ. YAML stands for Yet Another Markup Language). Ansible uses a YAML language to write the code (YAML is a data serialization language that is often used for writing configuration files. ![]() It turns our code into Infrastructure as Code(IAC).ģ. Ansible is agentless, temporarily connecting remotely via SSH or Windows Remote Management (allowing remote PowerShell execution) to do its tasks.Ģ. Ansible was written by Michael DeHaan and acquired by Red Hat in 2015. It includes its own declarative language to describe system configuration.ġ. It runs on many Unix-like systems and can configure both Unix-like systems as well as Microsoft Windows. (2) You could try and test a shortcut with the existing become plugin sudo and become_flags.Ansible is an open-source software provisioning, configuration management, and application-deployment tool enabling infrastructure as code. (1) You could just create your own customized become plugin based on the existing ansible/plugins/become/sudo.py, means just tweak it with an additional 'ip netns exec %s' % (become_network_namespace).Īfter a custom become plugin is created and provided, in example called as sudo_ns.py, one could use privilege escalation and a new to introduce fact become_network_namespace like - name: "download file archive" The solution lays within the Become plugins. ![]() ![]() Depending on how one look on it, it is quite simple. Is there some sort of Ansible task override to handle this scenario? ![]() How would you tackle this? Is there some sort of Ansible task override to handle this scenario? This would be fine for simple things like wget instead of get_url module, but would not work for things like the pip module when installing stuff from the internet. Run the tasks on the localhost (using delegate_to) and copy the files over.Run the desired commands as a command or shell task, instead of using individual modules (not best practice).So, because of this, regular Ansible commands that require reaching the internet do not work: - name: "download file archive" Or to wget a file, I need to do: sudo ip netns exec ns-mgmt wget I have some network gear that must run some commands within a network namespace in order to reach the internet.įor example, to install a pip package, I would do: sudo ip netns exec ns-mgmt pip3 install boto3 ![]()
