This is the documentation for the latest development version of Sonobuoy. Both code and docs may be unstable, and these docs are not guaranteed to be up to date or correct. See the latest version.

Release

Preparing release version

Update the version defined in the code to the new version number. As of the time of writing, the version is defined in pkg/buildinfo/version.go.

Kubernetes release

Is this release for a Kubernetes release? If so, apply the following steps:

Conformance images

Ensure the upstream conformance script is working appropriately:

Build the kind images for this new version.
1. Checkout K8s locally at the tag in question
2. Run make check-kind-env to ensure the repo/tag are correct
3. Run make kind_images
4. Run make push_kind_images
Update the kind-config.yaml file with the new image version here.

Setup e2e image registry for new version

Add the new list of E2E test images for the targed version.

Within pkg/image/, copy the latest v1.x.go file to a file which corresponds to the new Kubernetes release number.

For example, if the new Sonobuoy release corresponds to Kubernetes v1.20, copy the v1.19.go file to v1.20.go.

cd pkg/image
cp v1.{19,20}.go

This file will contain a function to return the list of test images via a map[int]Config value.

Update the name of the function accordingly. For example, if the file is for the v1.20 release, ensure the function name is v1_20.
Copy all map entries stored in variable configs from upstream Kubernetes file kubernetes/test/utils/image/mafnifest. Remove the previous map entries and replace them wi the The copied entries.
Update the GetImageConfigs function within pkg/image/manifest.go and add a new case statement to the minor version check which will be the minor version of the new Kubernetes release. In this new case, call the newly created function (e.g. r.v1_20()).
Add the new default image registry configuration by updating the function GetDefaultImageRegistries within pkg/image/manifest.go to return the default image registries for the new version.
- Add a new case to the minor version check which will correspond the minor version of the new Kubernetes release.
- Follow previous case statements (i.e. case 19:), return a new RegistryList object which includes only the registry keys used within the registry config for that version. Some registries are not applicable to include in this object as they are there to test specific image pull behavior such as pulling from a private or non-existent registry. This object should only include registries that can be successfully pulled from. The other registries are not used within the end-to-end tests.

Updating the versioned docs

Explicit doc changes (if any) should be made to the appropriate files in directory site/docs/master.

Next, generate a set of versioned docs for v0.x.y. For instance, the new docs be generated by running the command:

./scripts/update_docs.sh v0.20.0

This will copy the current master docs into the version given and update a few of the links in the README to be correct. It will also update the website config to add the new version and consider it the newest version of the docs.

Create PR

Commit previous changes and open a new PR
Ensure your commits signed
Follow PR build progress in circleci.com
Once all checks passes, merge accordingly

Tag release

This step will tag the code and triggers a release.

From your local branch, create an annotated tag for the commit that was merged:
```
 git tag -a v0.x.y -m "Release v0.x.y"
```
NOTE: Tag the new tip of master, not the branch you just merged.
Push the tag to the github.com/vmware-tanzu/sonobuoy repository.
To ensure that the tag is pushed to the correct repository, check which remote corresponds to that repository using the following command:
```
  git remote -v
```
The output of this command should include at least two configured remotes, typically origin, which refers to your personal fork, and upstream which refers to the upstream Sonobuoy repository. For example:
```
  origin	git@github.com:<username>/sonobuoy.git (fetch)
  origin	git@github.com:<username>/sonobuoy.git (push)
  upstream	https://github.com/vmware-tanzu/sonobuoy (fetch)
  upstream	https://github.com/vmware-tanzu/sonobuoy (push)
```
For the following steps, use the remote configured for the vmware-tanzu/sonobuoy repository. The following instructions will use upstream.
Push the tag with the following command.

NOTE: This will push all tags.
```
  git push upstream --tags
```
To push just one tag, use the following command format (replacing v0.x.y with the tag created in the previous step):
```
  git push upstream refs/tags/v0.x.y
```
If there is a problem and you need to remove the tag, run the following commands:
```
  git tag -d v0.x.y
  git push upstream :refs/tags/v0.x.y
```
NOTE: The : preceding the tag ref is necessary to delete the tag from the remote repository. Git refspecs have the format <+><src>:<dst>. By pushing an empty src to the remote dst, it makes the destination ref empty, effectively deleting it. For more details, see the git push documentation or this concise explanation on Stack Overflow.

Release Validation

Open a browser tab and go to: https://circleci.com/gh/vmware-tanzu/sonobuoy and verify go releaser for tag v0.x.y completes successfully.
Upon successful completion of build job above, check the releases tab of Sonobuoy and verify the artifacts and changelog were published correctly.
Run the following command to make sure the image was pushed correctly to Docker Hub:
```
docker run -it sonobuoy/sonobuoy:v0.x.y /sonobuoy version
```
The Sonobuoy Version in the output should match the release tag above.
Go to the GitHub release page and download the release binaries and make sure the version matches the expected values.
Run a Kind cluster locally and ensure that you can run sonobuoy run --mode quick. If this release corresponds to a new Kubernetes release as well, ensure:
- you’re using the correct Kubernetes context by checking the output from:
```
kubectl config current-context
```
  and verifying that it is set to the context for the Kind cluster just created (kind-kind or kind-<custom_cluster_name>)
- you’re testing with the new Kind images by checking the output from:
```
kubectl version --short
```
  and verifying that the server version matches the intended Kubernetes version.
- you can run sonobuoy images and get a list of test images as expected
Update the release notes if desired on GitHub by editing the newly created release.

Notes

Before releasing, ensure all parties are available to resolve any issues that come up. If not, just bump the release.

If you are building a Windows release you must currently build/push the Windows image outside of CI and push the manifest to also include it. To do this you must:

Have built the Windows binaries (can be done on a Linux box and should be the default now)
Have a Windows machine available for the build. The steps below will assume a docker context which is a Windows machine.
(Recommended) Build the sample Windows plugin (in our examples directory) to test the image
(Recommended) Have a cluster with Windows available for testing

docker context use default
make build/windows/amd64/sonobuoy.exe
docker context use 2019-box
make windows_containers
PUSH_WINDOWS=true make push
