* Add contrib/environment-to-ini This contrib command provides a mechanism to allow arbitrary setting of ini values using the environment variable in a more docker standard fashion. Environment variable keys should be structured as: "GITEA__SECTION_NAME__KEY_NAME" Use of the command is explained in the README. Partial fix for #350 Closes #7287 * Update contrib/environment-to-ini/environment-to-ini.go Co-Authored-By: 6543 <6543@obermui.de> Co-authored-by: Antoine GIRARD <sapk@users.noreply.github.com> Co-authored-by: 6543 <6543@obermui.de>

Environment To Ini
 | 
						|
==================
 | 
						|
 | 
						|
Multiple docker users have requested that the Gitea docker is changed
 | 
						|
to permit arbitrary configuration via environment variables.
 | 
						|
 | 
						|
Gitea needs to use an ini file for configuration because the running
 | 
						|
environment that starts the docker may not be the same as that used
 | 
						|
by the hooks. An ini file also gives a good default and means that
 | 
						|
users do not have to completely provide a full environment.
 | 
						|
 | 
						|
With those caveats above, this command provides a generic way of
 | 
						|
converting suitably structured environment variables into any ini
 | 
						|
value.
 | 
						|
 | 
						|
To use the command is very simple just run it and the default gitea
 | 
						|
app.ini will be rewritten to take account of the variables provided,
 | 
						|
however there are various options to give slightly different
 | 
						|
behavior and these can be interrogated with the `-h` option.
 | 
						|
 | 
						|
The environment variables should be of the form:
 | 
						|
 | 
						|
	GITEA__SECTION_NAME__KEY_NAME
 | 
						|
 | 
						|
Environment variables are usually restricted to a reduced character
 | 
						|
set "0-9A-Z_" - in order to allow the setting of sections with
 | 
						|
characters outside of that set, they should be escaped as following:
 | 
						|
"_0X2E_" for ".". The entire section and key names can be escaped as
 | 
						|
a UTF8 byte string if necessary. E.g. to configure:
 | 
						|
 | 
						|
	"""
 | 
						|
	...
 | 
						|
	[log.console]
 | 
						|
	COLORIZE=false
 | 
						|
	STDERR=true
 | 
						|
	...
 | 
						|
	"""
 | 
						|
 | 
						|
You would set the environment variables: "GITEA__LOG_0x2E_CONSOLE__COLORIZE=false"
 | 
						|
and "GITEA__LOG_0x2E_CONSOLE__STDERR=false". Other examples can be found
 | 
						|
on the configuration cheat sheet.
 | 
						|
 | 
						|
To plug this command in to the docker, you simply compile the provided go file using:
 | 
						|
 | 
						|
	go build environment-to-ini.go
 | 
						|
 | 
						|
And copy the resulting `environment-to-ini` command to /app/gitea in the docker.
 | 
						|
 | 
						|
Apply the below patch to /etc/s6/gitea.setup to wire this in.
