We don't necessarily want to include that script here in the main container image.

To my understanding, the lines here are newly added, right? There is some new handling of the Jupyter's URL compared to the one in
mspass/scripts/tacc_examples/single_node.sh
Lines 31 to 42 in 23898f4
What I would suggest is instead of handling the URL here inside of the startup script of the container, we should do it inside the job script instead (i.e., single_node.sh and distributed_node.sh). Then, we don't need to create a dedicated container for this specific purpose anymore.
Obviously, this do mean that we need to change how the main container is built so that we could specify a password by giving it an environment variable, and I do agree that we should incorporate that change inside the mspass container in general.
I can see that doing it inside of the job script means that we need some additional mechanism inside Tapis to change how containers are launched. We can discuss that further in our next meeting, but for the MsPASS repo, I figured it is better to use job script instead of creating dedicated container image.
