K3s Version

[Syndlex]

I have Problems updating a K3s Version.
The line Renovate should update looks like this.

# renovate: datasource=github-release depName=k3s-io/k3s versioning=regex:^v(?<major>\d+)(\\.(?<minor>\d+))?(\\.(?<patch>\\d+))\\+k3s?((?<build>\\d+))$
k3s_version: v1.21.6+k3s1

My Renovate Json defines a Regex Matcher Like this.

... 
 "regexManagers": [
    {
      "fileMatch": [
        "(^|/)all.yml$"
      ],
      "matchStrings": [
        "datasource=(?<datasource>.*?) depName=(?<depName>.*?)( versioning=(?<versioning>.*?))?\\s.*?_version: (?<currentValue>.*)\\s"
      ],
      "versioningTemplate": "{{#if versioning}}{{{versioning}}}{{else}}semver{{/if}}"
    }
  ]
...

The Log of Renovate gives me this json.

         "regex": [
           {
             "packageFile": "group_vars/all.yml",
             "deps": [
               {
                 "depName": "k3s-io/k3s",
                 "currentValue": "v1.21.6+k3s1",
                 "datasource": "github-release",
                 "versioning": "regex:^v(?<major>\\\\d+)(\\\\.(?<minor>\\\\d+))?(\\\\.(?<patch>\\\\d+))\\\\+k3s?((?<build>\\\\d+))$",
                 "replaceString": "datasource=github-release depName=k3s-io/k3s versioning=regex:^v(?<major>\\\\d+)(\\\\.(?<minor>\\\\d+))?(\\\\.(?<patch>\\\\d+))\\\\+k3s?((?<build>\\\\d+))$\nk3s_version: v1.21.6+k3s1\n",
                 "depIndex": 0,
                 "updates": [],
                 "warnings": [],
                 "skipReason": "invalid-config"
               }
             ],
             "matchStrings": [
               "datasource=(?<datasource>.*?) depName=(?<depName>.*?)( versioning=(?<versioning>.*?))?\\s.*?_version: (?<currentValue>.*)\\s"
             ],
             "versioningTemplate": "{{#if versioning}}{{{versioning}}}{{else}}semver{{/if}}"
           }

I don't get why the config should be invalid.

I tested the Regex with regex101: https://regex101.com/r/Kz04Be/1
I added extra \ when pasting it to the versioning field.

[viceice]

you forgot to escape some more \: (?<major>\d+) > (?<major>\\d+)

Don't escape with \ in your source file

[Syndlex]

To be Clear. The line in the source file should be this?

# renovate: datasource=github-release depName=k3s-io/k3s versioning=regex:^v(?<major>\d+)(\.(?<minor>\d+))?(\.(?<patch>\d+))\+k3s?((?<build>\d+))$
k3s_version: v1.21.6+k3s1

I also tried this and it didn't work.
The output from renovate was.

    "regex": [
      {
        "packageFile": "group_vars/all.yml",
        "deps": [
          {
            "depName": "k3s-io/k3s",
            "currentValue": "v1.21.6+k3s1",
            "datasource": "github-release",
            "versioning": "regex:^v(?<major>\\d+)(\\.(?<minor>\\d+))?(\\.(?<patch>\\d+))\\+k3s?((?<build>\\d+))$",
            "replaceString": "datasource=github-release depName=k3s-io/k3s versioning=regex:^v(?<major>\\d+)(\\.(?<minor>\\d+))?(\\.(?<patch>\\d+))\\+k3s?((?<build>\\d+))$\nk3s_version: v1.21.6+k3s1\n",
            "depIndex": 0,
            "updates": [],
            "warnings": [],
            "skipReason": "invalid-config"
          }
        ],
        "matchStrings": [
          "datasource=(?<datasource>.*?) depName=(?<depName>.*?)( versioning=(?<versioning>.*?))?\\s.*?_version: (?<currentValue>.*)\\s"
        ],
        "versioningTemplate": "{{#if versioning}}{{{versioning}}}{{else}}semver{{/if}}"
      }
    ]

Thanks for the fast response.

I use this, but in a packageRule:

    {
      "description": "Use custom regex versioning for k3s",
      "matchPackageNames": ["k3s"],
      "matchDatasources": ["github-releases"],
      "versioning": "regex:^v(?<major>\\d+)\\.(?<minor>\\d+)\\.(?<patch>\\d+)(?<compatibility>\\+k3s)(?<build>\\d+)$"
    }

I found the Problem. there is a missing s in my datasource "datasource": "github-release" should be "datasource": "github-releases"

@viceice how do you follow the stable branch of k3s?
I would like it if i only get Merge Requests for the Stable version. https://update.k3s.io/v1-release/channels

[viceice]

Nope, i mostly switch to next version when first or second patch is released. You need to read changelogs anyways.

Hello everyone,

Maybe a little late to the party but there is a very useful solution to this in the renovate documentation:
https://docs.renovatebot.com/modules/datasource/custom/

{
  "customManagers": [
    {
      "customType": "regex",
      "fileMatch": ["k3s.version"],
      "matchStrings": ["(?<currentValue>\\S+)"],
      "depNameTemplate": "k3s",
      "versioningTemplate": "semver-coerced",
      "datasourceTemplate": "custom.k3s"
    }
  ],
  "customDatasources": {
    "k3s": {
      "defaultRegistryUrlTemplate": "https://update.k3s.io/v1-release/channels",
      "transformTemplates": [
        "{\"releases\":[{\"version\": $$.(data[id = 'stable'].latest),\"sourceUrl\":\"https://github.com/k3s-io/k3s\",\"changelogUrl\":$join([\"https://github.com/k3s-io/k3s/releases/tag/\",data[id = 'stable'].latest])}],\"sourceUrl\": \"https://github.com/k3s-io/k3s\",\"homepage\": \"https://k3s.io/\"}"
      ]
    }
  }
}

k3s.version

v1.29.3+k3s1

@Syndlex @viceice
This makes sure you only get stable versions as well :-)
