Is not clear to me why your error mentions docker compose! Or TCL for that matter.

The first thing I need to ask is are you running this on a DLS Red hat 8 workstation? 2nd did you run the podman setup script supplied by the cloud team? (If not search for podman in confluence to find it)

olliesilvester commented 10 months ago

Yes this is a DLS red hat 8 workstation, and I have run the startup script. I had some issues with it but it seems to have worked eventually (https://jira.diamond.ac.uk/browse/HLA-767)

gilesknap commented 10 months ago

Ok. Can you try podman system reset and report any errors you see.

Then try c7 again

I'm going to need to take a look at your machine probably.

I'm not back in the office until Thurs.

In the mean time what happens if you run

podman run -it ubuntu​

OK, thanks!

That command gives:

That is as expected so podman is working on your workstation.

I've just verified that c7 is working for me as per the instructions here https://dls-controls.github.io/dev-c7/main/tutorials/start.html.

One thing I note about those instructions is that they assume $HOME/bin is in your path. Are you able to verify that:

  1. You are using the latest c7 script from https://raw.githubusercontent.com/dls-controls/dev-c7/main/c7

  2. That you are definitely launching that script (i.e. if you type which c7 it shows the file you downloaded from the above.

I expect I need to come an have a look at your workstation tomorrow as this is probably something specific to your setup.

olliesilvester commented 10 months ago

$HOME/bin wasn't on my path, although I get the same error after adding it. I can verify my script is the latest one and that which c7 points to ~/bin/c7

gilesknap commented 10 months ago

Hi @olliesilvester unfortunately I'm going to be working from home for a few more days because my car is broken.

Let me know what your machine name is and I'll see if I can connect an reproduce the issue.

olliesilvester commented 10 months ago

No problem, I am ws103

gilesknap commented 10 months ago

Sorry for the delay, I'm still stuck at home for this week. Back on Mon next.

I could not reproduce any problems on your ws103 machine.

I did notice that your account loads modules that add docker-compose to the path. Please can you report what happens if you remove "/dls_sw/dasc/tools:/dls_sw/apps/docker-compose/2.23.0/bin:" from your PATH and run c7 again.

olliesilvester commented 10 months ago

Removing this from the path seemed to fix it, thank you!

gilesknap commented 10 months ago

I guess that is not a permanent fix as you might need those things - now we need to track down who provides the modulet that adds it to your path.

olliesilvester commented 10 months ago

It was on my bash rc - I think someone recommended I add it when I first joined diamond but I guess it's outdated now

gilesknap commented 10 months ago

OK great, I figure we can close this issue then. I have used docker compose in the past and I may not have tried launching dev-c7 with it - I don't fully understand the interaction but will look into it again if it becomes an issue for anyone.

olliesilvester commented 10 months ago

Thanks for your help!
