Using curl to either check or download a script file in Otter

[scusson_9923]

Hello Alana,

We want to add to our current functionality and make it backward compatible. We have an archive job running in Jenkins which then uploads a config file to Otter and triggers a job. That Otter job runs remotely using Otter\PowerShell scripts with that config file and an input. What we want to do is have a related archive job with its own config file use the same Otter\PowerShell scripts. The issue is, we cannot guarantee that both config files will exist. It would help greatly if we can conditionally get an asset.

Thanks,
Scott

Hi @scusson_9923 ,

One idea ... how about a try/catch block?

It's not great.... but the catch will indicate the file doesn't exist.

Just a thought...

Thanks,
Alana

Hello Alana,

I tried that, but the catch returns as error if the file doesn't exist and fails the job.

Thanks,
Scott

Hi @scusson_9923 ,

Can you share the OtterScript where you tried the try/catch ? Perhasp that's just something we can more easily fix.

Hello Dean,

Here is a test script:

try
{
    Get-Asset FooBar.ps1
    (
        Overwrite: true,
        Type: Script,
        To: D:\temp\FooBar.ps1
    );
}
catch
{
    Log-Information did we catch?;
}

Here is the Otter output:

DEBUG: Beginning execution run...
INFO: Execution run succeeded.
DEBUG: Beginning execution run...
INFO: Execution run succeeded.
DEBUG: Beginning execution run...
INFO: Execution run succeeded.
DEBUG: Beginning execution run...

Hi @scusson_9923 ,

Sorry on the slow reply; i wanted to test this, but didn't get a chance and figure I'd just share this now (which should work):

set $scriptExists = true;

try
{
    Get-Asset FooBar.ps1
    (
        Overwrite: true,
        Type: Script,
        To: D:\temp\FooBar.ps1
    );
}
catch
{
    set $scriptExists = false;
    force normal;
}

Log-Information scriptExists: $scriptExists;

Cheers,
Steve

Hi Steve,

Unfortunately, I still get 'ERROR: The raft Default does not contain an asset of type Script with the name FooBar.ps1.'

Thanks,
Scott

Hi @scusson_9923 ,

The message is expected, but you should see scriptExists: false written at the end, and aNormal status (i.e. green) for the execution.

Is that not the case?

Thanks,
Steve

[scusson_9923]

Hi Steve,

scriptExists does come back as false. But my main point is that the job is marked as failure regardless. Odd that I see 'INFO: Execution run succeeded' in a job failure. I assume that this message indicates that the process itself did not experience any "internal errors"?

Thanks,
Scott

Hi @scusson_9923 ,

Looks like this is a bug in not overriding the job/execution status; the force normal statement should make it "green" and a normal execution status. Anyway we'll get it fixed via OT-524.

Cheers,
Steve
