title: 'Custom User Changes & Patches | Scripting'
|
|
---
|
|
|
|
If you'd like to change, patch or alter files or behavior of `docker-mailserver`, you can use a script.
|
|
|
|
In case you cloned this repository, you can copy the file [`user-patches.sh.dist` (_under `config/`_)][github-file-userpatches] with `#!sh cp config/user-patches.sh.dist docker-data/dms/config/user-patches.sh` in order to create the `user-patches.sh` script.
|
|
|
|
If you are managing your directory structure yourself, create a `docker-data/dms/config/` directory and add the `user-patches.sh` file yourself.
|
|
|
|
``` sh
|
|
# 1. Either create the docker-data/dms/config/ directory yourself
|
|
# or let docker-mailserver create it on initial startup
|
|
/tmp $ mkdir -p docker-data/dms/config/ && cd docker-data/dms/config/
|
|
|
|
# 2. Create the user-patches.sh file and edit it
|
|
/tmp/docker-data/dms/config $ touch user-patches.sh
|
|
/tmp/docker-data/dms/config $ nano user-patches.sh
|
|
```
|
|
|
|
The contents could look like this:
|
|
|
|
``` sh
|
|
#!/bin/bash
|
|
|
|
cat >/etc/amavis/conf.d/50-user << "END"
|
|
use strict;
|
|
|
|
$undecipherable_subject_tag = undef;
|
|
$admin_maps_by_ccat{+CC_UNCHECKED} = undef;
|
|
|
|
#------------ Do not modify anything below this line -------------
|
|
1; # ensure a defined return
|
|
END
|
|
|
|
```
|
|
|
|
And you're done. The user patches script runs right before starting daemons. That means, all the other configuration is in place, so the script can make final adjustments.
|
|
|
|
!!! note
|
|
Many "patches" can already be done with the Docker Compose-/Stack-file. Adding hostnames to `/etc/hosts` is done with the `#!yaml extra_hosts:` section, `sysctl` commands can be managed with the `#!yaml sysctls:` section, etc.
