The following message is printed when you ssh to the ondemand instance:

Steps to reproduce:

• from the outside ssh to frontend as hpcadmin ssh -p 6222 hpcadmin@localhost
• from frontent ssh to ondemand with this command ssh ondemand
• error message is printed after the MOTD

It appears to be this ~/.bash_profile. I can't tell when these were changed from rhel/7 to 8, but since we're on 8, this scl_source isn't required for 8.

The following message is printed when you ssh to the ondemand instance:

I'm unable to reproduce. What OS/Docker version are you running? Can you double check you have the latest images: ./hpcts cleanup; ./hpcts start.

Sounds good. We should be able to just remove that line. However, while this line exists in the ondemand docker image it shouldn't be used anyway. We mount /home as a volume and the home from the underlying image is not used.

This is what I see after running ./hpcts start:

$ docker volume ls | grep home
local     hpc-toolset-tutorial_home

$ ssh -p 6222 hpcadmin@localhost
[hpcadmin@frontend ~]$ ssh ondemand
[hpcadmin@ondemand ~]$ cat /home/hpcadmin/.bash_profile 
# .bash_profile

if [ -f ~/.bashrc ]; then
    . ~/.bashrc

Login to ondemand and it appears we add it again!

Ok then! Unless I'm missing something, it's a harmless warning correct? If so, we can add this to the TODO for PEARC23.

Yea I can submit a patch soon while it's on our minds, but we don't need to release more containers. It is harmless and will keep until PEARC23.
