#+TITLE: Bind v9 Domain name server
* Usage
** Example =compose.yml=
#+begin_src yaml
dns:
charm: bind
options:
vars:
## these vars are a facility to allow using `$var` in domain defs
myip: 1.2.3.4
zones:
## __all__ will be applied to all domains defined here
__all__:
ns:
## '_' is translated to '@' in BIND v9 zone definition, which in
## in turn refers to the current domain being defined.
_: (dns.mycompany.com,sdns1.ovh.net,ns6.gandi.net)
mx:
_: (1 ,(5 alt(1,2),10 alt(3,4)).)aspmx.l.google.com.
mycompany.com:
mx:
news: 10 news
## Names will generate IN A/CNAME depending if an IP is detected or a name
name:
## key and values can be expanded, the syntax uses the same logic
## than shell expansion with `{`, `}` and `,`. So this:
## `(_,dns,core(,-01))` will demux to `_ dns core core-01`, so all
## these keys will receive the following value.
(_,dns,core(,-01)): $myip
core-02: 4.5.6.7
## You can specify after a space, a TTL that will be applied to all
## definitions inside the section:
name 3h:
## `www` required not to be an IP by zonecheck
(www,admin,smtp,beta,alpha,erp(,-beta)): core-01
news: 77.32.131.26
r.news: r.mailin.fr.
img.news: img.mailin.fr.
spf 3h:
## Remember that this is YAML that also offer nice syntaxic
## feature to avoid repeating values.
_: &spf >-
v=spf1 a
a:smtp.free.fr
a:smtp.mycompany.com
include:spf.sendinblue.com
mx ?all
txt 3h:
_:
- *spf
- Sendinblue-code:xxx
- google-site-verification=yyy
news: "v=spf1 include:spf.sendinblue.com mx ~all"

pct=100;
ri=86400
(othercompany.com,other-company.com):
name:

#+end_src
* Persistence
backup will keep:
- /etc/bind/rndc.key
- /etc/bind/.db.$DOMAIN files keeping a hash of the configuration along
with the given serial that matches the zone file. This is to be sure to
advertise the same serial after a recovery.
