Running OnDemand inside Docker container

Get Help
1

Hi,

I am currently building container to run OnDemand from Ubuntu base image. I have set the OnDemand in the container up till authentication, but when I try to log in with the credentials, I do not get the dashboard.
When I checked the logs I get this error: App 573 output: [2024-10-25 09:15:17 +0200 ] ERROR “[ActionDispatch::HostAuthorization::DefaultResponseApp] Blocked host: my_domain_name.com”.
I have not mounted the host home directory to the container, instead created a user inside the container, as I am currently only testing the container locally.

Also is it a good idea to run OnDemand inside container and deploying it on login node for production, would it create any issue with the scheduler?

Thank you,
Varun

I wouldn’t say it is no. I think deploying the package on a VM/login node is the better route.

If you’re looking to build and interact with a container locally (on your own machine) I’d follow these instructions on how to get a development container going. This is what I use when I need to hack around on something. Note that it’s not meant to run in production, but can give you some insight into what configuration you may be missing.

Hi Jeff,

Thanks for the info.
This one looks good for testing, and for production we will do the VM / bare metal solution.
