Garden Linux Release Database (GLRD)

This repository contains tooling and configuration to create the Garden Linux Release Database (GLRD), a system designed to manage and query release information for the Garden Linux distribution.

This repository contains these tools:

glrd-manage: A tool for generating and populating the GLRD with initial release data and for creating individual release entries.
glrd: A command-line client for querying the GLRD to retrieve release information based on various criteria.

Garden Linux Releases

For a general overview about Garden Linux releases and their lifecycle, have a look at the Garden Linux Release Plan Overview.

Overview

The GLRD provides a structured way to store and access release data for Garden Linux, including different release types such as stable, patch, nightly, and development releases. It uses JSON and YAML formats to store release information and supports integration with AWS S3 for storage to host release data..

Run GLRD

Manually run Python scripts

Details

Prerequisites

Python 3.6+

You can install the required Python packages using:

pip install -r requirements.txt

AWS CLI configured with appropriate permissions if you plan to use S3 integration.
Git and GitHub CLI (gh) installed and configured if you plan to generate release data from GitHub.

Installation

Clone the repository and ensure that the scripts are executable:

git clone https://github.com/gardenlinux/glrd.git
cd glrd
pip install -e .

Run in container

Details

You can also use the GLRD tools by building or running a container image.

Run pre-build image

podman run -it --rm ghcr.io/gardenlinux/glrd glrd
podman run -it --rm -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY -e AWS_SESSION_TOKEN ghcr.io/gardenlinux/glrd glrd-manage

Build and run image locally

podman build -t glrd .
podman run -it --rm glrd glrd
podman run -it --rm -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY -e AWS_SESSION_TOKEN glrd glrd-manage

Run in GitHub action

Details

  - name: Get latest GL patch version
    id: gl_version_latest
    uses: gardenlinux/glrd@main
    with:
      cmd: glrd --no-header --type patch --latest --fields Version
  - name: Use latest GL patch version
    run: echo ${{ steps.gl_version_latest.outputs.result }}

  - name: Get latest GL nightly version
    id: gl_version_nightly
    uses: gardenlinux/glrd@main
    with:
      cmd: glrd --no-header --type nightly --latest --fields Version
  - name: Use latest GL nightly version
    run: echo ${{ steps.gl_version_nightly.outputs.result }}

Manually query JSON data

Details

You can manually query the release JSON data by getting them from our production S3 bucket.

Query the release type that you want:

releases-stable.json
releases-patch.json
releases-nightly.json
releases-dev.json

To e.g. query the stable releases:

❯ curl -s https://gardenlinux-glrd.s3.eu-central-1.amazonaws.com/releases-stable.json
{"releases":[{"name":"stable-27","type":"stable","version":{"major":27},"lifecycle":{"released":{"isodate":"2020-06-09","timestamp":1591694693},"extended":{"isodate":"2020-12-09","timestamp":1607472000},"eol":{"isodate":"2021-03-09","timestamp":1615248000}}},{"name":"stable-184","type":"stable","version":{"major":184},"lifecycle":{"released":{"isodate":"2020-10-29","timestamp":1603984625},"extended":{"isodate":"2020-04-29","timestamp":1588118400},"eol":{"isodate":"2021-07-29","timestamp":1627516800}}},{"name":"stable-318","type":"stable","version":{"major":318},"lifecycle":{"released":{"isodate":"2021-04-28","timestamp":1619614135},"extended":{"isodate":"2021-10-28","timestamp":1635379200},"eol":{"isodate":"2023-01-28","timestamp":1674864000}}},{"name":"stable-576","type":"stable","version":{"major":576},"lifecycle":{"released":{"isodate":"2021-11-17","timestamp":1637142852},"extended":{"isodate":"2023-05-17","timestamp":1684281600},"eol":{"isodate":"2023-08-17","timestamp":1692230400}}},{"name":"stable-934","type":"stable","version":{"major":934},"lifecycle":{"released":{"isodate":"2023-06-05","timestamp":1685968163},"extended":{"isodate":"2023-12-05","timestamp":1701734400},"eol":{"isodate":"2024-03-05","timestamp":1709596800}}},{"name":"stable-1312","type":"stable","version":{"major":1312},"lifecycle":{"released":{"isodate":"2023-11-16","timestamp":1700136050},"extended":{"isodate":"2024-05-03","timestamp":1714694400},"eol":{"isodate":"2024-08-03","timestamp":1722643200}}},{"name":"stable-1443","type":"stable","version":{"major":1443},"lifecycle":{"released":{"isodate":"2024-03-13","timestamp":1710341636},"extended":{"isodate":"2024-09-13","timestamp":1726185600},"eol":{"isodate":"2025-01-13","timestamp":1736726400}}},{"name":"stable-1592","type":"stable","version":{"major":1592},"lifecycle":{"released":{"isodate":"2024-08-12","timestamp":1723457202},"extended":{"isodate":"2025-05-12","timestamp":1747008000},"eol":{"isodate":"2025-08-12","timestamp":1754956800}}}]}

AWS Authentication

glrd-manage needs write access to an AWS S3 bucket to create and manage releases. See Boto3 Credentials documentation and ways to configure this. If you are running glrd-manage in a container, you might want to use Environment variables and pass those via e.g. podman run ... -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY -e AWS_SESSION_TOKEN.

options:
  -h, --help            show this help message and exit
  --delete DELETE       Delete a release by name (format: type-major.minor). Requires --s3-update.
  --create-initial-releases CREATE_INITIAL_RELEASES
                        Comma-separated list of initial releases to retrieve and generate: 'stable,patch,nightly'.
  --create CREATE       Create a release for this type using the current timestamp and git information (choose one of: stable,patch,nightly,dev,next)'.
  --version VERSION     Manually specify the version (format: major.minor).

  --log-level {ERROR,WARNING,INFO,DEBUG}

Testing release creation

Files named releases-${type}.json will be created in the current working directory.

Without passing --s3-update, no actual update will be made and changes can safely be tested and verified locally.

Generate and populate initial release data

This will generate the following initial release data ...

stable releases
patch releases
nightly releases
releases from releases-input.yaml (contain manual lifecycle fields)

... and upload it to the default S3 bucket (if --s3-update is passed).

❯ glrd-manage --create-initial-releases stable,patch,nightly --input

Generate/Update an arbitrary release from JSON/YAML data

This will generate/update a release from JSON data and upload it to the default S3 bucket.

❯ echo '{
  "releases": [
    {
      "name": "patch-1592.1",
      "type": "patch",
      "version": {
        "major": 1592,
        "minor": 1
      },
      "lifecycle": {
        "released": {
          "isodate": "2024-08-22",

        },
        "eol": {
          "isodate": "2025-08-12",

      }
    }
  ]
}' | glrd-manage --input-stdin

Another approach is writing release YAML data to an input file and use this file as input parameter.

❯ cat releases-input.yaml

  - name: patch-1592.1
    type: patch
    version:
      major: 1592

❯ glrd-manage --input --input-file releases-input.yaml

Create or update a stable release

https://github.com/gardenlinux/glrd?tab=readme-ov-file#default-stable-dates When creating a new stable release, Default Stable dates can be automatically set for you. In addition to that, you can also overwrite the dates by hand.

# use default dates
❯ glrd-manage --create stable --version 1312

# overwrite default dates
❯ glrd-manage --create stable --version 1312 --date-time-released 2023-11-16T00:00:00 --date-time-extended 2024-05-03T00:00:00 --date-time-eol 2024-08-03T00:00:00

Create or update a patch release

When creating a new patch release, the previous patch release of the same major release gets automatically updated. See Lifecycle Dependencies for details.

# create new patch
❯ glrd-manage --create patch --version 1312.7

Create a new nightly release

Without any additional parameters, the current timestamp and git information will be used to create releases. For patch, nightly and dev releases, the next free minor version is automatically chosen.

❯ glrd-manage --create nightly

  - timestamp: The UNIX timestamp of the release date.
- extended:
  - isodate: Optional extended maintenance date in ISO format.
  - timestamp: Optional UNIX timestamp for the extended maintenance date.
- eol:
  - isodate: End-of-life date in ISO format.
  - timestamp: UNIX timestamp for the end-of-life date.

Lifecycle Dependencies

The lifecycle fields in the release schemas help track the release dates, extended maintenance dates and end-of-life (EOL) dates for each release.

Default Stable dates

The defaults for extended and eol dates are based on the Garden Linux Release Plan Overview and defined to be:

extended
- released + 6 month
eol
- released + 9 month

For example:

Stable Release stable-1443:
- released: 2024-03-13
- extended: 2024-09-13
- eol: 2025-01-13

Stable and Patch releases

There is a dependency between the lifecycle fields of stable and patch releases:

EOL of Patch Releases: The eol date of a patch release is set to the released date of the next patch release. If there is no subsequent patch release, the eol date is aligned with the eol date of the corresponding stable release.
EOL of Latest Patch Release: The latest patch release's eol date matches the eol date of the stable release.
EOL of Stable Releases: The eol date for a stable release marks the end of support for that major version.

This ensures that all minor updates within a major release adhere to the same overall support timeline.

For example:

Stable Release stable-1312:
- released: 2023-11-16
- extended: 2024-05-03
- eol: 2024-08-03
Patch Release patch-1312.1:
- released: 2023-11-23
- eol: 2024-01-15 (next patch release date)
Patch Release patch-1312.2:
- released: 2024-01-15
- eol: 2024-02-14 (next patch release date)
...
Patch Release patch-1312.7:
- released: 2024-07-03
- eol: 2024-08-03 (inherits from stable release eol)

In this example, the eol of patch-1312.1 is set to the released date of patch-1312.2, and the eol of the latest patch release (patch-1312.7) is set to the eol of the stable release (patch-1312).

Please note that the extended lifecycle field is not taken into account for patch releases. This is simply an administrative date that has no technical implications.

Nightly an Dev dates

Due to the nature of the nightly and dev releases, those do not have extended and eol dates.
