The binary itself doesn't sandbox your processes unless you're in the nsjail mode. Hence, if you either use the binary raw (without docker) or mount the filesystem to be available to your container, it can run anything that is available on the filesystem.
I didn't succeed to return all output from the powershell, just last value. The only way I got it is by using control "job log". This one however has some custom header of windmill (job guid etc.), so is there any way to show a raw log ?
I generally do not like no-code tools, but first impression of this mix of no-code and code looks intriguing and app feels very nice overall, with great UI and easy to understand features. Good job.
However, we had that feedback a few time so there is a trick. If you write your result in ./result.json, we will process it as the result of your powershell script.
Am I able to install it on Windows? I need windows specific things, such as powershell remoting. One of the good things about Rundeck is that server acts as worker, and it runs on Windows without problems (Installing it is as simple as choco install rundeck). I can then use all windows tools, run applications (including GUI ones) etc. just the same as if I run them outside rundeck, using OTB powershell.
Regarding "Connection to the main database" as far as my use case is, all the settings could live in the file system json files or sqlite if that makes installation trivial for the use case of being very good job scheduler with options to create great jobs UI, logs and management of small number of users (which is a fairly common scenario).
