Pass a readable JSON as string into Nomad Template

Question

We are using nomad template to add environment variables for our nomad deployments.

      template {
  data = <<EOH
Key1=value1
Key2=value2
Key3=AJsonstring
EOH

  change_mode = "restart"
  destination = "environments/file.env"
  env         = true
}

I notice that nomad requires me to escape my JSON string in order for me to properly pass it in. Ie: say i want to pass in {"a":3,"b":4} in Key3 I cannot just write it as is, instead, i had to write "{\"a\":3,\"b\":4}" which is a lot less readable.

Is there a way so I can just pass the plain string in and make it to interprets it as is?

Answer 1

I'd try using single quotes around your JSON object: key3='{"a": 3, "b": 4 }'.

$ echo {"a": 1}
{a: 1}
$ echo '{"a": 1}'
{"a": 1}

note: I haven't tested this! Just a guess based on how I'd expect things are put together.
