Make sure that you replace your-managed-host-ip with your host IP address. So let's create one: # cd /etc/ansibleĪdd the following lines in your hosts' file and save it: ĭocker_host ansible_host=your-managed-host-ip ansible_user=ansadmin ansible_ssh_private_key_file=/home/ansadmin/.ssh/ansible-CN ansible_python_interpreter=/usr/bin/python3 If you remember, earlier, the hosts' file was not created automatically for our Ansible. In this file, we can define groups and sub-groups. The default location for the inventory resides in /etc/ansible/hosts.
Ansible docker network password#
Now, if you wish, you can disable Password Authentication on both machines.Īnsible allows us to manage multiple nodes or hosts at the same time. Enter the password for ansadmin, and you are done. ssh/ansible-CN.pub the first time, it will ask for the password. Switch to Control Node machine to copy the public key to our Managed Host machine, we will use the command ssh-copy-id: $ su - ansadmin Other than this, it is also an excellent thing to cross-check if password authentication is enabled on the Managed Host as we need to copy the ssh public key from the control node to the Managed Host. Please make sure that the password for the username ansadmin is the same for Control and Managed Host. Now let us configure our Managed Host for Ansible.įirst, we will create a user on our managed host, so log in to your host and create a user with the same name and password.Īs our managed host is an Ubuntu machine, therefore here we have to use the adduser command. In our case, you can find keys at /home/ansadmin/.ssh/. SHA256:6G0xzIrIsmsBwCakACI8CVr8AOuRR8v5F1p2+CsB6EY key's randomart image is: Your public key has been saved in ansible-CN.pub.

Your identification has been saved in ansible-CN. Use ssh-keygen command to generate key: # ssh-keygenĮnter file in which to save the key (/home/ansadmin/.ssh/id_rsa): ansible-CNĮnter passphrase (empty for no passphrase): To generate the private and public key, follow the below-mentioned commands: # su - ansadmin Now, log in as an ansadmin user on your Control Node and generate ssh key, which we will use to connect with our remote or managed host. To reflect changes, reload the ssh service: # service sshd reload You will see why we are doing this in the next few steps. To enable it, follow the below-mentioned steps: # nano /etc/ssh/sshd_configįind PasswordAuthentication, uncomment it and replace no with yes, as shown below. By default, SSH password authentication is disabled in our instance. īefore moving forward, we have one last thing to do. Go to the end of the file and paste the below-mentioned line as it is. To do so, follow the below-mentioned steps: # nano /etc/sudoers Once we have created the user, it's time to grant sudo access to it, so it doesn't ask for a password when we log in as root. Passwd: all authentication tokens updated successfully.Ĭopy the password for user ansadmin and save it somewhere safe. Make sure that you use a strong password.
Ansible docker network update#
Now, use the passwd command to update the ansadmin user’s password. So let’s create a user, by using the command adduser, which will create a new user to our system: # useradd ansadmin The first thing we are going to do is create a user named ansadmin, as it is considered the best practice. Through the above command, we notice that the config file path is missing, which we will create and configure later. Once the installation is complete, verify: # ansible -versionĬonfigured module search path = Īnsible python module location = /usr/lib/python2.7/site-packages/ansible It might take a minute or two to complete the installation, so sit tight.
Ansible docker network install#
Use the below-mentioned command to do so: # sudo yum updateĪfter Python is installed on the system, use pip2 command to install Ansible on the Control Node: # sudo pip2 install ansible To install Ansible, we are going to use python2-pip, and to do so, first, we have to install python2.

Here we are using CentOS 8 as our Ansible Control Node. Let us begin the guide by installing Ansible on our Control node. To overcome this limitation, Ansible plays an integral part as a shell script executor, which enables Jenkins to execute the workflow of a process. Still, sometimes, it gets overwhelming to maintain the application's status, and script reusability becomes harder as the project grows. In the world of CI/CD process, Jenkins is a popular tool for provisioning development/production environments as well as application deployment through pipeline flow. In this guide, we will use Ansible as a Deployment tool in a Continuous Integration/Continuous Deployment process using Jenkins Job.
