Multi-prefix on JSON configuration file gets overwritten

[calvn]

@sethvargo I was wondering if you have looked into this. I can start working on this and send you a PR if you are busy

@cleung2010 thank you for opening an issue.

The JSON you supplied is not a direct translation from the HCL. Top-level keys in HCL are actually keys to arrays of objects in JSON, i.e.:

consul = "127.0.0.1:8500"
token = "abcd1234"
retry = "10s"
max_stale = "10m"

auth {
  enabled = true
  username = "test"
  password = "test"
}

becomes:

{
  "auth": [
    {
      "enabled": true,
      "password": "test",
      "username": "test"
    }
  ]
}

Are you experiencing issues when you specify the prefixes as an array of objects, because that should definitely work?

So I am not using HCL at all as my config file. I want to use multi-prefix via JSON. The readme says I can do it like so in HCL:

prefix {
  source = "global@nyc1"
  destination = "local/nyc1"
}

prefix {
  source = "global@nyc2"
  destination = "local/nyc2"
}

But how can I do this in JSON since keys need to be unique (thus two prefix wouldn't work)?

[sethvargo]

@cleung2010 the same as my example for auth (and the example you provided yourself above):

{
  "prefix": [
    {
      "source": "...",
      "destination": "..."
    }
  ]
}

[calvn]

Oh nice, and I assume the same would apply for destination. I am going to go ahead and close the issue, thanks for clearing this up! It wouldn't hurt to provide a JSON example on the readme for people less familiar with explicit translations done by HCL :)

[sethvargo]

@cleung2010 no, destination must be a string. It's the same as the command line. If you want multiple destinations, you need to specify the prefix multiple times.

[calvn]

So

{
"prefix": [
        {
            "destination": "local/nyc1",
            "source": "global@nyc1"
        },
        {
            "destination": "local/nyc2",
            "source": "global@nyc2"
        },
        {
            "destination": "temp/nyc2",
            "source": "global@nyc2"
        }
    ]
}

Instead of

{
"prefix": [
        {
            "destination": "local/nyc1",
            "source": "global@nyc1"
        },
        {
            "destination": [
                "local/nyc2",
                "temp/nyc2"
            ],
            "source": "global@nyc2"
        }
    ]
}

[sethvargo]

Yes

Cool, thanks!
