Hi all,
I am working on an idea for an Ansible role that installs CUDA, where I
want to have a var consisting of a list of items with multiple key/value
pairs (some values being lists of items.) So I came up with this YAML data
structure, in a file I named cuda_versions.yml:
---
cuda_versions:
- cuda_8_0:
cuda_ver: 8.0.61
min_driver_ver: 375.26
installer_url:
https://developer.nvidia.com/compute/cuda/8.0/Prod2/local_installers/cuda_8.0.61_375.26_linux-run
patchset_url_list:
-
https://developer.nvidia.com/compute/cuda/8.0/Prod2/patches/2/cuda_8.0.61.2_linux-run
- cuda_9_0:
cuda_ver: 9.0.176
min_driver_ver: 384.81
installer_url:
https://developer.nvidia.com/compute/cuda/9.0/Prod/local_installers/cuda_9.0.176_384.81_linux-run
patchset_url_list:
-
https://developer.nvidia.com/compute/cuda/9.0/Prod/patches/1/cuda_9.0.176.1_linux-run
-
https://developer.nvidia.com/compute/cuda/9.0/Prod/patches/2/cuda_9.0.176.2_linux-run
-
https://developer.nvidia.com/compute/cuda/9.0/Prod/patches/3/cuda_9.0.176.3_linux-run
-
https://developer.nvidia.com/compute/cuda/9.0/Prod/patches/4/cuda_9.0.176.4_linux-run
- cuda_9_1:
cuda_ver: 9.1.85
min_driver_ver: 387.26
installer_url:
https://developer.nvidia.com/compute/cuda/9.1/Prod/local_installers/cuda_9.1.85_387.26_linux
patchset_url_list:
-
https://developer.nvidia.com/compute/cuda/9.1/Prod/patches/1/cuda_9.1.85.1_linux
-
https://developer.nvidia.com/compute/cuda/9.1/Prod/patches/2/cuda_9.1.85.2_linux
-
https://developer.nvidia.com/compute/cuda/9.1/Prod/patches/3/cuda_9.1.85.3_linux
- cuda_9_2:
cuda_ver: 9.2.148
min_driver_ver: 396.37
installer_url:
https://developer.nvidia.com/compute/cuda/9.2/Prod2/local_installers/cuda_9.2.148_396.37_linux
patchset_url_list:
-
https://developer.nvidia.com/compute/cuda/9.2/Prod2/patches/1/cuda_9.2.148.1_linux
- cuda_10_0:
cuda_ver: 10.0.130
min_driver_ver: 410.48
installer_url:
https://developer.nvidia.com/compute/cuda/10.0/Prod/local_installers/cuda_10.0.130_410.48_linux
patchset_url_list:
Which when turned into an Ansible var via include_vars: ./cuda_versions.yml
has the structure:
"cuda_versions": [
{
"cuda_8_0": {
"cuda_ver": "8.0.61",
"installer_url":
"https://developer.nvidia.com/compute/cuda/8.0/Prod2/local_installers/cuda_8.0.61_375.26_linux-run";,
"min_driver_ver": 375.26,
"patchset_url_list": [
"https://developer.nvidia.com/compute/cuda/8.0/Prod2/patches/2/cuda_8.0.61.2_linux-run";
]
}
},
{
"cuda_9_0": {
"cuda_ver": "9.0.176",
"installer_url":
"https://developer.nvidia.com/compute/cuda/9.0/Prod/local_installers/cuda_9.0.176_384.81_linux-run";,
"min_driver_ver": 384.81,
"patchset_url_list": [
"https://developer.nvidia.com/compute/cuda/9.0/Prod/patches/1/cuda_9.0.176.1_linux-run";,
"https://developer.nvidia.com/compute/cuda/9.0/Prod/patches/2/cuda_9.0.176.2_linux-run";,
"https://developer.nvidia.com/compute/cuda/9.0/Prod/patches/3/cuda_9.0.176.3_linux-run";,
"https://developer.nvidia.com/compute/cuda/9.0/Prod/patches/4/cuda_9.0.176.4_linux-run";
]
}
},
{
"cuda_9_1": {
"cuda_ver": "9.1.85",
"installer_url":
"https://developer.nvidia.com/compute/cuda/9.1/Prod/local_installers/cuda_9.1.85_387.26_linux";,
"min_driver_ver": 387.26,
"patchset_url_list": [
"https://developer.nvidia.com/compute/cuda/9.1/Prod/patches/1/cuda_9.1.85.1_linux";,
"https://developer.nvidia.com/compute/cuda/9.1/Prod/patches/2/cuda_9.1.85.2_linux";,
"https://developer.nvidia.com/compute/cuda/9.1/Prod/patches/3/cuda_9.1.85.3_linux";
]
}
},
{
"cuda_9_2": {
"cuda_ver": "9.2.148",
"installer_url":
"https://developer.nvidia.com/compute/cuda/9.2/Prod2/local_installers/cuda_9.2.148_396.37_linux";,
"min_driver_ver": 396.37,
"patchset_url_list": [
"https://developer.nvidia.com/compute/cuda/9.2/Prod2/patches/1/cuda_9.2.148.1_linux";
]
}
},
{
"cuda_10_0": {
"cuda_ver": "10.0.130",
"installer_url":
"https://developer.nvidia.com/compute/cuda/10.0/Prod/local_installers/cuda_10.0.130_410.48_linux";,
"min_driver_ver": 410.48,
"patchset_url_list": null
}
}
]
Now I am stuck trying to get a value from a given key for a given item key
in Ansible. For example, how would one get the "installer_url" value for
the "cuda_9_0" item key from this var in Ansible? I tried a few things, but
none of them have worked, and this is the most complicated var list that
I've yet worked with :)
Or, is there a better way to structure my YAML so that it produces a better
(more Ansible-friendly, easier to work with) data structure?
