nomad multiline environment variable

Question

Is there a way to have a multiline environment variable in a nomad template? Trying it directly gives an error about not being able to find the closing quote.

In the docs the only function that's mentioned is | toJSON, but that translates the line feeds into \n so the receiving end needs to do a search-and-replace or some "unJSON" function.

I tried using HEREDOC syntax in the template, but that didn't seem to work either.

Seem we can generate multiline file using nomad templates data with heredoc and lets the service read that file. — kholisrag, Jul 29 '22 at 18:46

Using a here document works fine:

job "example" {
  datacenters = ["dc1"]
  type = "service"
  group "cache" {
    task "redis" {
      driver = "docker"
      config {
        image = "redis:7"
      }
      env {
        EXAMPLE = <<EOF
multiline
varibale
is
here
EOF
      }
    }
  }
}

It's been half a year now so I don't recall exactly what I was doing, but maybe my issue was indenting the `EOF`. – Tim Tisdall Feb 17 '23 at 16:48
