Update either Server or Role Variables

Jonathan.Engstrom

Is it possible to update a variable for a server based on code? For example, can I create a variable called OS and have it populate based on CIM_OperatingSystem or WMI? More specifically edit a variable on a server?

Product: Otter
Version: 2.0.13

You could use the Variables Management API for this:

So I have been working on different ways to update a server, and I am having some issues. I can create a new server, or add a new server to a role no problem with the code below. But Updating variables, I am getting this:

Invoke-RestMethod : 547160Variables_CreateOrUpdateVariable57`The INSERT statement conflicted with the FOREIGN KEY constraint "FK__Variables__Servers".

$Key= 'blahblah'
$Server = 'hdarsintsv1'

$Body =
'{
"variables": {
"Viking": "True",
},
}'

Invoke-RestMethod $URI -Method Post -Body $Body -Verbose

Any ideas? Thanks!

Forgot to add this too:

$URI = "https://azlmidrange.azlifem.azl.pvt:8626/api/infrastructure/servers/update?key=$key"

My bad!

So I am able to update all of the attributes of a server, with the exception of variables. I am able to edit roles, environments, temppath, drift, all without issue. I am not able to change server variables, though. Can anyone test this to confirm it may be a bug, or perhaps I am doing something wrong? Being I can update everything else, I am going to side with the former, but anything's possible.

$Key= 'blahblah'

$Server = 'hdarsintsv1'

$URI = "https://otterserver.test:8626/api/infrastructure/servers/update/$Server`?key=$key"

$Body =

'{

 "variables": 
 
 {
     "Viking": "True",
     
 },

}'

Invoke-RestMethod $URI -Method Post -Body $Body -Verbose

That is indeed a bug in that particular API, but in the meantime the variables API can be used as follows:

$VariableObj = @{
    name = "Viking"
    value = "True"
    server = "hdarsintsv1"	
}

$Headers = @{
    "X-ApiKey" = "blahblah"
}

Invoke-RestMethod "http://otterint/api/variables/scoped/single" -Method Post `
    -Body ($VariableObj | ConvertTo-Json) `
    -Headers $Headers -Verbose

I am not familiar with this way to do it, and it does not appear to work for me:

Invoke-RestMethod : The underlying connection was closed: An unexpected error occurred on a receive.

This appears to be an issue when using headers, but I have not found a reliable way to fix this.

You can adapt it to your method (i.e. just use JSON directly as you did in your previous example), I just already had this script handy and don't like putting the API key in the query string if I can avoid it.

Thanks John. I did try a few variations, and after I ended up renaming a server trying to get your method to work, I decided to stop trying. I am not very familiar with the format you are using, and it is different from the documentation. However, I agree that not adding the key to the URL string is probably a safer way to do it, and that process and examples should be added to the documentation.

I still am not able to update a variable, but if one creates a new server, then you can add variables as long as it's a create. Maybe that will help whoever is going to fix it.

Ahh I see the confusion now. The important bit is that I am using a completely different API (i.e. the Variables Management API that Tod originally mentioned at /api/variables, not the Infrastructure API at /api/infrastructure) to accomplish the same task as a workaround. These endpoints are also far more powerful for variables specifically (i.e. you can edit multiple at once, handle multi-scoping, etc.)

As I mentioned, what you did originally is supposed to work, and there is a bug filed to fix for the next release: https://inedo.myjetbrains.com/youtrack/issue/OT-257

Alright, after messing around with that information, I was able to get it to work. I am able to update the variables. Interesting thing is that it doesn't appear I can change just one variable, I have to change all of them, or at least enter all of them as they are?

Thanks for your help!
