## vault + KeePass LookUp-Plugin
|
||||
|
||||
### Einrichtung
|
||||
Das Plugin wird bei einer Installation mit dem Playbook "ansible" mit eingerichtet.
|
||||
|
||||
Die "Secrets" liegen in der KeepassDB die mit dem Kennwort aus `vault-pass.yml` verschlüsselt ist.
|
||||
`vault-pass.yml` steht mit in der .gitignore
|
||||
Die Variable `vault_password_file` ist mit `~/ansible/vault-pass.yml` in der `ansible.cfg` gesetzt.
|
||||
Diese Datei enthält das Passwort mit dem die KeePassDB verschlüsselt ist.
|
||||
Das vault-secret für die GroupVars wird mit `ansible-vault encrypt_string <password>` erstellt.
|
||||
|
||||
### Erklärung
|
||||
|
||||
```yaml
|
||||
keepass_dbx: "./keepass_db.kdbx"
|
||||
keepass_psw: !vault |
|
||||
$ANSIBLE_VAULT;1.1;AES256
|
||||
62383737XXXXXX531
|
||||
```
|
||||
|
||||
1. mit `vault-pass.yml` wird das Kennwort an ansible-vault übergeben
|
||||
2. ansible-vault entschlüsselt hiermit die Variable `keepass_psw`
|
||||
3. der Inhalt der Variable wird dann an das KeePass-Lookup-Plugin übergeben was damit die KeePass-Datei öffnet
|
||||
|
||||
### Abfrage der Secrets in tasks/playbooks
|
||||
`restic_repository_password: "{{ lookup('keepass', 'restic_repository_password', 'password') }}"`
|
||||
|
||||
#### Erklärung
|
||||
|
||||
```yaml
|
||||
restic_repository_password: <-- Ansible Variablen Name
|
||||
lookup('keepass' <-- Aufruf Keepass-Lookup-Plugin
|
||||
restic_repository_password <-- Titel Eintrag mit Secret
|
||||
password <-- Feldbzeichner in KeepassDB
|
||||
```
|
||||
|
||||
## Inventory anzeigen
|
||||
`ansible-inventory -i inventory --graph`
|
||||
|
||||
## Alternatives Dictionary Format
|
||||
|
||||
```bash
|
||||
zfs_pool:
|
||||
- name: "ssd_vm_mirror"
|
||||
type: "ssd"
|
||||
cron_minute_zfs_trim: "5"
|
||||
cron_hour_zfs_trim: "22"
|
||||
cron_month_zfs_trim: "4,8,12"
|
||||
cron_day_zfs_trim: "2"
|
||||
cron_weekday_zfs_scrub: "6"
|
||||
cron_minutes_zfs_scrub: "0"
|
||||
cron_hour_zfs_scrub: "23"
|
||||
```
|
||||
|
||||
ist das gleiche wie:
|
||||
|
||||
```yaml
|
||||
zfs_pool:
|
||||
- { name: "ssd_vm_mirror", type: "ssd", cron_minute_zfs_trim: "5", cron_hour_zfs_trim: "22", cron_month_zfs_trim: "4,8,12", cron_day_zfs_trim: "2", cron_weekday_zfs_scrub: "6", cron_minutes_zfs_scrub: "0", cron_hour_zfs_scrub: "23"}
|
||||
```
|
||||
|
||||
## when: true
|
||||
`Use when: var rather than when: var == True (or conversely when: not var)`
|
||||
`when: dokuwiki_update # entspricht when: dokuwiki_update == true`
|
||||
|
||||
## Loop + Join
|
||||
### Vars
|
||||
|
||||
```yaml
|
||||
mountpoint: "/shares"
|
||||
sources:
|
||||
- "/dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_drive-scsi1"
|
||||
- "/dev/disk/by-id/scsi-0QEMU_QEMU_HARDDISK_drive-scsi2"
|
||||
opts: defaults,allow_other,direct_io,use_ino,moveonenospc=true,category.create=mfs,minfreespace=100G
|
||||
```
|
||||
|
||||
### Tasks
|
||||
|
||||
```yaml
|
||||
- name: "Join/Combine sources"
|
||||
set_fact:
|
||||
src: "{{sources | join (':')}}"
|
||||
loop: "{{ sources }}"
|
||||
|
||||
- debug:
|
||||
msg: "{{src}}"
|
||||
|
||||
- name: "Mount mergerFS"
|
||||
mount:
|
||||
path: "{{ mountpoint }}"
|
||||
src: "{{ src }}"
|
||||
opts: "{{ opts }}"
|
||||
fstype: fuse.mergerfs
|
||||
state: mounted
|
||||
```
|
||||
|
||||
## prüfen ob eine Datei existiert
|
||||
|
||||
```yaml
|
||||
- name: check if migration file exists
|
||||
stat:
|
||||
path: /etc/miniflux.d/.migration_successful
|
||||
register: migration_successful_existiert
|
||||
|
||||
- name: migration tocuh
|
||||
file:
|
||||
path: /etc/miniflux.d/.migration_successful
|
||||
state: touch
|
||||
when: migration_successful_existiert.stat.exists == False
|
||||
```
