Bash variables with curly braces ${} in template files

[Igor Cicimov]

Hi,

Is there a way to tell TF that:

${var1:$((${#var1}-1)):1}

is bash variable in a shell script that's being rendered as template? Or is there any way of escaping this kind of vars so TF does not think they are var placeholders?

Thanks,
Igor

Use double dollar, $$, to escape interpolation.

_doh_, no idea how did I missed that or forgot about, it's in the very first paragraph of the interpolation document page ... Thanks, Michael.

I have the same issue. But when I use $$, terraform plan accepts it but terraform apply does not. Also the $$var in bash passes the name of the variable preceded by number 2. I am really stuck and don't know what to do. I'd really appreciate any help.
