Apache SkyWalking Go Release Guide

This documentation guides the release manager to release the SkyWalking Go in the Apache Way, and also helps people to check the release for vote.

Prerequisites

Close(if finished, or move to next milestone otherwise) all issues in the current milestone from skywalking-go and skywalking, create a new milestone if needed.
Update CHANGES.md.
Check the dependency licenses including all dependencies.

Add your GPG public key to Apache svn

Upload your GPG public key to a public GPG site, such as MIT’s site.
Log in id.apache.org and submit your key fingerprint.
Add your GPG public key into SkyWalking GPG KEYS file, you can do this only if you are a PMC member. You can ask a PMC member for help. DO NOT override the existed KEYS file content, only append your key at the end of the file.

Build and sign the source code package

export VERSION=<the version to release>
git clone git@github.com:apache/skywalking-go && cd skywalking-go
git tag -a "v$VERSION" -m "Release Apache SkyWalking-Go v$VERSION"
git tag -a "toolkit/v$VERSION" -m "Release Apache SkyWalking-Go Toolkit v$VERSION"
git push --tags
make release

In total, six files should be automatically generated in the directory: apache-skywalking-go-${VERSION}-bin.tgz, apache-skywalking-go-${VERSION}-src.tgz, and their corresponding asc, sha512 files.

Remove Unnecessary Releases

Please remember to remove all unnecessary releases in the mirror svn (https://dist.apache.org/repos/dist/release/skywalking/), if you don’t recommend users to choose those version.
