Does it work if you escape the $ using $$ ?

I'm not sure there is anything we can do about this. $ is now a special character, and needs to be escaped.

It does work with the escaping. These docker-compose.yml files worked before and then stopped after I upgraded, I missed the variable substitution section of the documentation.

Closing.
