Question Docker: Environment Variables with "=" are not allowed - why?

[Tim Weyand]

Hi,
i have a problem with an Docker Container. The Container has an Environment Variable which influence the runtime command. By Default in may be used unchanged or overwritten.

In Plesk Onyx 17.5.3 i have the problem, that there is:

1. no way to keep the default value
2. Plesk does not allow "=" in Environment Variables (XSS prevention?)

Is there anyway to use the Container, or do I have to rewrite it for Plesk? I tried escaping it already (screenshot)

Best,
Tim

Could you please clarify why you can't specify the path to vcl Varnish config as VCL_CONFIG variable like in this article Varnish HTTP Cache plugin for Wordpress in a Docker container ?

Hi Igor,
nice Blogpost As I said I could rewrite the Dockerfile or for that instance use another Docker (for example: million12/varnish) container.

As I wanted to use a Docker, which we have in our Production Cluster - the Question remains how and if I can use "=" in Environment Variables or how I do not change the Default Variables given in a Dockerfile.

@Tim Weyand At the moment there is no opportunity to use = symbol in Environment Variables. I would recommend you create the corresponding report here https://talk.plesk.com/forums/reports.746/ and I will forward it to the responsible person in Plesk Team for the further consideration.
Thanks.
