Create your own customized vagrant base box

 



Below are steps to modify the vagrant image and save it for future use

 1. Login to you vagrant machine. Here I am taking example of Ubuntu 16.04
vagrant ssh

 2. Remove APT cache
sudo apt-get clean

 For Centos you can use 
yum clean all

 3. Reduce the size of OS
sudo dd if=/dev/zero of=/EMPTY bs=1M
sudo rm -f /EMPTY

 4. Exit from the VM and create vagrant base box
vagrant package --output mynew.box
Note: You should run the command in same folder where Vagrantfile is located for customized VM

 5. Add the mynew.box to vagrant box repository
vagrant box add myubuntu16 mynew.box

 6. Verify if box is added
vagrant box list

 7. Now you can deploy your customized VM
vagrant init myubuntu16

Using ansible ping module check connectivity between two nodes

Using ansible ping module check connectivity between two nodes Once server and client machine is configured with SSH passwordless authentication and  ansible installed in server, we will verify if ansible can connect from server to client. If you have not configured refer page Login to server node and create a directory to save all the work done in one location Eg:mywork [root@ansible ~]# mkdir mywork [root@ansible ~]# cd mywork/ Create new file called "hosts" under "mywork" and add your client host name in the file as shown below. [root@ansible mywork]# cat hosts [mynodes] node01 Now is the time to check if ansible from server machine able to communicate to client node01 To check this we will use ansible module called ping. Run command as shown below. [root@ansible mywork]# ansible all -i hosts -u root -m ping node01 | SUCCESS => {     "changed": false,     "ping": "pong" }
