Why dotfiles with Ansible ?

• Config files derivation by host or by OS with jinja2 templating
• It can manage packages too
• Secrets with Ansible-vault
• Multiple hosts and ability to update a config on all hosts from a single command

Test VMs|Containers

Please check vagrant/*/README.md and docker/*/README.md

Docs

Please look at roles/*/README.md if exists for specific hosts configuration.

How to

** Use carefully** backup your home before using ! Ansible will backup any existing conf file before overriding.

1. Fork Me!

2. Clone your repo on a personal host

git clone --recursive https://github.com/[your_repo]/dotfiles
cd dotfiles

3. Generate ssh keys

ssh-keygen -t rsa

4. Replace your ssh key in authorized_keys role

!!! Use as is, you will add my SSH key in your authorized_keys !!!

cp ~/.ssh/id_rsa.pub dotfiles/roles/authorized_keys/id_rsa.pub

5. Generate hosts file with your managed hosts

hosts file is defaultly gitignored.

cd dotfiles
mv hosts.template hosts

Add your hosts in right sections

• server : install only cli tools
• desktop : install graphic environment
• laptop : install desktop + some extra packages

Please explicitly define an ansible_user which will receive configurations

[server]
server1 ansible_user=root
[laptop]
host1 ansible_user=user
[desktop]
host2 ansible_user=user2

Remove useless groups and hosts

6. Deploy SSH keys on nodes

Node per node if password differ between users. It adds your public ssh keys on hosts

ansible-playbook install.yml -t init_ssh -l host1 -k
ansible-playbook install.yml -t init_ssh -l host2 -k
ansible-playbook install.yml -t init_ssh -l host3 -k

7. Run ansible-playbook

For runs on hosts configured with root user You can use without providing extra passwords

ansible-playbook install.yml -l server

For hosts configured with non-root user User needs to be in sudoers. You need to use -K to ask sudo password, and -l to limit to that host

ansible-playbook install.yml -l host1 -K --ask-vault-pass

Extra commands

To list tasks and tags

ansible-playbook install.yml --list-tasks

To limit to a tag

ansible-playbook install.yml -K -t <tag>

To dry-run and print files diff on all declared hosts

ansible-playbook install.yml -l host1 -CDK

Local run

Add localhost line and user in right hosts file section

[server]
[laptop]
localhost ansible_connection=local ansible_user=user
[desktop]

ansible-playbook install.yml -l localhost -K --ask-vault-pass
