Page History

These instructions coemplement complement those from http://sling.apache.org/documentation/development/release-management.html, which are geared more towards bundle releases, while releasing the Launchpad is a bit more involved.

...

Since the Launchpad is a collection of bundles, it is required for each bundle included it in to be a release, rather than a SNAPSHOT. We currently have only releases in the starter, so this should not be an issue.

It is not recommended to group the Sling Starter and other bundles in the same release vote. The Sling Docker images are automatically built on DockerHub when a release tag is created and it a bundle is missing since it is not yet released the build will fail and will need to be manually recovered. It is possible to trigger a new build later on by deleting the release tag and creating it again but it complicates the release process and is therefore not recommended.

The diagram below shows the projects that were released for Sling 11 and their dependencies. Some unrelated dependencies (blue) were also released as they were used as snapshots. Only one archetype (magenta) was released as the others did not need any changes.

...

Since the Sling 8 release we also provide a docker image. The Dockerfile can be found in the sling-org-apache-sling-starter-docker repo. Images are deployed by tagging the repository with the version of Sling they correspond to, for instance:

git tag -a 11
git push --tags

After the tags are pushed the DockerHub build can be triggered.  We since we trigger builds based on Github tags, the type of build we use is  source_type: Tag . For more details , see the /repos/private/pmc/sling SVN repository. The build status for ongoing builds can be verified at https://hub.docker.com/r/apache/sling/builds/ .

. As of the Sling Starter 12 release, the process is automated using DockerHub automated builds . Pushing a tag of the form org.apache.sling.starter-$VERSION  will result in a DockerHub tag of $VERSION  and also in the latest  tag being updated.

There is no direct access to the DockerHub UI. If needed, a set of credentials that can be used to trigger builds are stored in the private Sling PMC area in SVN.

The automated builds setup was configured in

Image AddedNote that, like for any Apache artifacts, the sling-org-apache-sling-starter-docker module must be released before deploying binaries (like the Docker image) to public places.

Update local references to the old starter

...

Clean up starter documentation

There may be references to old features of the starter at https://sling.apache.org/documentation/the-sling-engine/the-sling-launchpad.html, so make sure that this is up to dateThe latest version of the Sling Starter is defined in the Sling site by the sling_releaseVersion  variable in src/main/jbake/templates/includes/U.groovy . Once changed, it i recommended to verify it is used, in case usage patterns have changed from the previous version.

Update the Apache Sling Wikipedia page
