# ansible

The ansible files for the pains-perdus infra.

## Deploy a playbook

`ansible-playbook playbook.yml`

Add `--check` to do a dry run

## Edit the vault

`ansible-vault edit group_vars/all/vault`

with the edditor defined in the env varible `$EDITOR` and the password of the vault in the file `.vault_password` (Carefull not to commit it!!!)

## SSH key whith passphrase

To avoid entering the passphrase of the ssh key for each host, we have to use an ssh-agent.
The ssh-agent with xonsh does not really works, so in my case I have to use ansible and the agent inside a sh process:

```
sh
eval `ssh-agent -s`
ssh-add
ansible all -m ping # or whatever you want to do with ansible
exit
```

## Vault managment

To use multiple vaults with multiple password, we use vault id.
The mapping vault-id@password-file is done in ansible.cfg under [defaults] in vault_identity_list:
`vault_identity_list = main_vault@.main_vault_password , user_vault@.user_vault_password`

To create a new vault with an id and password registered in ansible.cfg:
`ansible-vault create --encrypt-vault-id user_vault group_vars/all/user_vault`

## User managment

The user managment role allows to manage user.

Especially, it generate the described users on each hosts. 

The password are stored in the variables in there hash form. The script `hash_passwd.py` can give you the hash of a password.
