Hi, I've got an issue trying to parse special characters into CONFIG\_STRING in my dockerfile.  
I'm not sure here is the right place to ask, but figured someone might've come across this before.

If I try to parse

```auto
    ENV ELASTICSEARCH_HOST "https://..."

```

Error:  
_Failed to execute action {:action=\>LogStash::PipelineAction::Create/pipeline\_id:main, :exception=\>"LogStash::ConfigurationError", :message=\>"Expected one of [A-Za-z0-9\_-], [\t\r\n], "#", "{", [A-Za-z0-9\_], "}" at line 1, column 71 (byte 71) after output { elasticsearch {hosts =\> https"_

It seems to want alphanumeric characters, but I need to parse my ':' which the config file ofcourse does just take.

Any help is extremely appreciated!

Nicky

There ought to be a double quote before the https. It will be choking on the :// that follows it.

Thanks for the swift reply @Badger.

The Environment variables ELASTICSEARCH\_HOST has this. I've now also tried to trough CONFIG\_STRING but exists at the same command.. ☹
