app.Usage = "Use provided environment to update configuration ini"
|
|
app.Description = `As a helper to allow docker users to update the gitea configuration
|
|
through the environment, this command allows environment variables to
|
|
be mapped to values in the ini.
|
|
|
|
Environment variables of the form "GITEA__SECTION_NAME__KEY_NAME"
|
|
will be mapped to the ini section "[section_name]" and the key
|
|
"KEY_NAME" with the value as provided.
|
|
|
|
Environment variables of the form "GITEA__SECTION_NAME__KEY_NAME__FILE"
|
|
will be mapped to the ini section "[section_name]" and the key
|
|
"KEY_NAME" with the value loaded from the specified file.
|
|
|
|
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.`
