#### **--dns**=*ipaddr*

|
|
Set custom DNS servers.
|
|
|
|
This option can be used to override the DNS
|
|
configuration passed to the container. Typically this is necessary when the
|
|
host DNS configuration is invalid for the container (e.g., **127.0.0.1**). When this
|
|
is the case the **--dns** flag is necessary for every run.
|
|
|
|
The special value **none** can be specified to disable creation of _/etc/resolv.conf_ in the container by Podman.
|
|
The _/etc/resolv.conf_ file in the image is then used without changes.
|
|
|
|
Note that **ipaddr** may be added directly to the container's _/etc/resolv.conf_.
|
|
This is not guaranteed though. For example, passing a custom network whose *dns_enabled* is set to *true* to **--network** will result in _/etc/resolv.conf_ only referring to the aardvark-dns server. aardvark-dns then forwards to the supplied **ipaddr** for all non-container name queries.
