JASMIN localmirrors

[Caro.Duran.Rojas (caroduro)]

I am wokring on a suite u-dk105 that works fine to get the source code from a "localmirrors:MetOffice/SimSys_Scripts.git" location for Metoffice computers. We would like to run same suite on JASMIN HPC. Is there any instructions to follow on how to create a local mirror on JASMIN HPC?
Any information will be really appreciated.

Hi Caro.Duran.Rojas (@caroduro),
SimSys_Scripts is a public repository. Could you not modify your suite to retrieve the repository from GitHub instead?
Regarding how to create a local mirror on Jasmin, I think that question should be directed to the Jasmin admin.

[Caro.Duran.Rojas (caroduro)]

The suite is modified accordingly to run on JASMIN, but it is failing with :

[INFO] 2026-10-15T12:35:21+0100 git ls-remote --exit-code localmirrors:MetOffice/SimSys_Scripts.git main
PluginError: Error in plugin cylc.post_install.rose_opts
ConfigProcessError: file:bin/get_git_sources.py=source=git:localmirrors:MetOffice/SimSys_Scripts.git::github_scripts/get_git_sources.py::main: ls-remote: could not locate 'localmirrors:MetOffice/SimSys_Scripts.git':
    ssh: Could not resolve hostname localmirrors: Name or service not known
    fatal: Could not read from remote repository.

    Please make sure you have the correct access rights
    and the repository exists.

Or can you recommend a way to extract the JULES code from git, without the localmirrors option?

[Mohit Dalvi (mcdalvi)]

Caro.Duran.Rojas (@caroduro) I have not used this suite, but looking at rose-suite.conf you will need to replace git:localmirros at the top with https://github.com (and same for any other paths with localmirrors). Then set JASMIN_USE_MIRRORS=false; JASMIN_USE_TOKENS=true.
There should be JASMIN documentation for setting up GitHub access via tokens.

[James Bruten (james-bruten-mo)]

Yes, this is the right approach.
The documentation for the structure of the source extraction from github is in the rose docs at https://metomi.github.io/rose/doc/html/api/configuration/file-creation.html

[Caro.Duran.Rojas (caroduro)]

Mohit Dalvi (@mcdalvi), I did change the lines you suggested :

[file:bin/get_git_sources.py]
source=https://github.com:MetOffice/SimSys_Scripts.git::github_scripts/get_git_sources.py::main

[file:bin/merge_sources.py]
source=https://github.com:MetOffice/SimSys_Scripts.git::github_scripts/merge_sources.py::main

but now I am getting the following error:

Any idea how to solve this?
Thanks

OFFICIAL Hi, See the rose documentation linked by James above for extracting files. The entries that I have come across and seem to work are written as: source=git:https://github.com/MetOffice/ OFFICIAL

That was sorted I did read the info from rose, but I couldn't figure out how to write it, as it has several ":" in the line.
Thanks
