6 minute read
This document guides maintainers through the process of creating an Envoy Gateway release.
Release Candidate
The following steps should be used for creating a release candidate.
Prerequisites
- Permissions to push to the Envoy Gateway repository.
Set environment variables for use in subsequent steps:
export MAJOR_VERSION=0
export MINOR_VERSION=3
export RELEASE_CANDIDATE_NUMBER=1
export GITHUB_REMOTE=origin
Clone the repo, checkout the
main
branch, ensure it’s up-to-date, and your local branch is clean.Create a topic branch for adding the release notes and updating the VERSION file with the release version. Refer to previous release notes and VERSION for additional details.
Sign, commit, and push your changes to your fork.
Submit a Pull Request to merge the changes into the
main
branch. Do not proceed until your PR has merged and the Build and Test has successfully completed.Create a new release branch from
main
. The release branch should be namedrelease/v${MAJOR_VERSION}.${MINOR_VERSION}
, e.g.release/v0.3
.git checkout -b release/v${MAJOR_VERSION}.${MINOR_VERSION}
Push the branch to the Envoy Gateway repo.
git push ${GITHUB_REMOTE} release/v${MAJOR_VERSION}.${MINOR_VERSION}
Create a topic branch for updating the Envoy proxy image and Envoy Ratelimit image to the tag supported by the release. Reference PR #2098 for additional details on updating the image tag.
Sign, commit, and push your changes to your fork.
Submit a Pull Request to merge the changes into the
release/v${MAJOR_VERSION}.${MINOR_VERSION}
branch. Do not proceed until your PR has merged into the release branch and the Build and Test has completed for your PR.Ensure your release branch is up-to-date and tag the head of your release branch with the release candidate number.
git tag -a v${MAJOR_VERSION}.${MINOR_VERSION}.0-rc.${RELEASE_CANDIDATE_NUMBER} -m 'Envoy Gateway v${MAJOR_VERSION}.${MINOR_VERSION}.0-rc.${RELEASE_CANDIDATE_NUMBER} Release Candidate'
Push the tag to the Envoy Gateway repository.
git push ${GITHUB_REMOTE} v${MAJOR_VERSION}.${MINOR_VERSION}.0-rc.${RELEASE_CANDIDATE_NUMBER}
This will trigger the release GitHub action that generates the release, release artifacts, etc.
Confirm that the release workflow completed successfully.
Confirm that the Envoy Gateway image with the correct release tag was published to Docker Hub.
Confirm that the release was created.
Note that the Quickstart Guide references are not updated for release candidates. However, test the quickstart steps using the release candidate by manually updating the links.
Generate the GitHub changelog.
Ensure you check the “This is a pre-release” checkbox when editing the GitHub release.
If you find any bugs in this process, please create an issue.
Setup cherry picker action
After release branch cut, RM (Release Manager) should add job cherrypick action for target release.
Configuration looks like following:
cherry_pick_release_v0_4:
runs-on: ubuntu-latest
name: Cherry pick into release-v0.4
if: ${{ contains(github.event.pull_request.labels.*.name, 'cherrypick/release-v0.4') && github.event.pull_request.merged == true }}
steps:
- name: Checkout
uses: actions/checkout@b4ffde65f46336ab88eb53be808477a3936bae11 # v4.1.1
with:
fetch-depth: 0
- name: Cherry pick into release/v0.4
uses: carloscastrojumo/github-cherry-pick-action@a145da1b8142e752d3cbc11aaaa46a535690f0c5 # v1.0.9
with:
branch: release/v0.4
title: "[release/v0.4] {old_title}"
body: "Cherry picking #{old_pull_request_id} onto release/v0.4"
labels: |
cherrypick/release-v0.4
# put release manager here
reviewers: |
AliceProxy
Replace v0.4
with real branch name, and AliceProxy
with the real name of RM.
Minor Release
The following steps should be used for creating a minor release.
Prerequisites

Set environment variables for use in subsequent steps:
export MAJOR_VERSION=0
export MINOR_VERSION=3
export GITHUB_REMOTE=origin
Clone the repo, checkout the
main
branch, ensure it’s up-to-date, and your local branch is clean.Create a topic branch for adding the release notes, release announcement, and versioned release docs.
- Create the release notes. Reference previous release notes for additional details. Note: The release notes should be an accumulation of the release candidate release notes and any changes since the release candidate.
- Create a release announcement. Refer to PR #635 as an example release announcement.

git checkout -b release/v${MAJOR_VERSION}.${MINOR_VERSION} $GITHUB_REMOTE/release/v${MAJOR_VERSION}.${MINOR_VERSION}
If the tip of the release branch does not match the tip of
main
, perform the following:Create a topic branch from the release branch.
Cherry-pick the commits from
main
that differ from the release branch.Run tests locally, e.g.
make lint
.Sign, commit, and push your topic branch to your Envoy Gateway fork.
Submit a PR to merge the topic from of your fork into the Envoy Gateway release branch.
Do not proceed until the PR has merged and CI passes for the merged PR.
If you are still on your topic branch, change to the release branch:
git checkout release/v${MAJOR_VERSION}.${MINOR_VERSION}
Ensure your local release branch is up-to-date:
git pull $GITHUB_REMOTE release/v${MAJOR_VERSION}.${MINOR_VERSION}
Tag the head of your release branch with the release tag. For example:
git tag -a v${MAJOR_VERSION}.${MINOR_VERSION}.0 -m 'Envoy Gateway v${MAJOR_VERSION}.${MINOR_VERSION}.0 Release'
Note: The tag version differs from the release branch by including the
.0
patch version.Push the tag to the Envoy Gateway repository.
git push origin v${MAJOR_VERSION}.${MINOR_VERSION}.0
