A crawler for kernel releases distributed by the major Linux distributions.
It supports, Amazon Linux v1, Amazon Linux v2, Amazon Linux 2022, Centos, Debian, Ubuntu, Fedora, Oracle Linux, OpenSUSE Linux, Arch Linux.
The crawling data is continuously published and is available at db.krawler.dev.
krawler [options] <command>
-c, --config file: (optional) the config file to customize the list of mirrors to scrape for kernel releases (by default it looks at $HOME/.krawler.yaml).-v, --verbosity level: (optional) the verbosity level (debug, info, warn, error, fatal, panic). By (default warning).
List available kernel releases with distributed headers, by Linux distribution.
It returns a list of kernelRelease objects. The output format can be specified by flag parameter.
krawler [options] list|ls <distribution> [-o <format>]
distribution: (required) The Linux distribution for which the release has been pubished.
Available distributions:
- amazonlinux
- amazonlinux2
- amazonlinux2022
- centos
- debian
- ubuntu
- fedora
- oracle
- opensuse
- archlinux
-o, --output format: (optional) the format of the output of the list of kernel releases (one of text, json or yaml). By default yaml.
The list|ls command prints on standard ouput a is a list of kernel release objects of type KernelRelease.
An example of a json result entry:
{
"full_version": "4.18.0",
"version": 4,
"patch_level": 18,
"sublevel": 0,
"extra_version": "331",
"full_extra_version": "-331.el8.aarch64",
"architecture": "aarch64",
"package_name": "kernel-devel",
"package_url": "https://mirrors.edge.kernel.org/centos/8-stream/BaseOS/aarch64/os/Packages/kernel-devel-4.18.0-331.el8.aarch64.rpm",
"compiler_version": "80500"
}
Let's imagine you want to list the available CentOS kernel releases, scraping default mirrors. You do it by running:
krawler ls centos
A configuration lets you configure parameters for the crawling, like the mirrors to scrape.
The default configuration file path is $HOME/.krawler.yaml. You can specify a custom path with the --config option.
When a configuration is not present, a default configurations for repositories are used (for example this is the default for Centos).
For a detailed overview see the reference.
Moreover, sample configurations are available here.
- Provide GCC versions for all releases
- Support new distributions
