$(basename "${BASH_SOURCE[0]}"): Update the Fedora Linux image location in the specified templates
15+
16+
Usage:
17+
$(basename "${BASH_SOURCE[0]}") [--version (<version number>|release|development[/<version number>]|rawhide)] <template.yaml>...
18+
19+
Description:
20+
This script updates the Fedora Linux image location in the specified templates.
21+
Image location basename format:
22+
23+
Fedora-Cloud-Base[-<target vendor>]-<version>-<build info>.<arch>.qcow2
24+
Fedora-Cloud-Base[-<target vendor>].<arch>-<version>-<build info>.qcow2
25+
26+
Published Fedora Linux image information is fetched from the following URL:
27+
28+
${fedora_image_list_url}
29+
30+
The downloaded files will be cached in the Lima cache directory.
31+
32+
Examples:
33+
Update the Fedora Linux image location in templates/**.yaml:
34+
$ $(basename "${BASH_SOURCE[0]}") templates/**.yaml
35+
36+
Update the Fedora Linux image location to version 41 in ~/.lima/fedora/lima.yaml:
37+
$ $(basename "${BASH_SOURCE[0]}") --version 41 ~/.lima/fedora/lima.yaml
38+
$ limactl factory-reset fedora
39+
40+
Flags:
41+
--version <version> Use the specified version.
42+
The version must be <version number>, 'release', 'development[/<version number>]', or 'rawhide'.
43+
-h, --help Print this help message
