|
|
* `alpine:3.13.5` for JLINK distributions.
|
|
* `scratch` for NATIVE_IMAGE distributions.
|
|
|
|
== Default Labels
|
|
|
|
JReleaser will add the following labels if they are not explicitly defined:
|
|
|
|
* org.opencontainers.image.title = {{distributionName}}
|
|
* org.opencontainers.image.description = {{projectDescription}}
|
|
* org.opencontainers.image.url = {{projectWebsite}}
|
|
* org.opencontainers.image.licenses = {{projectLicense}}
|
|
* org.opencontainers.image.version = {{projectVersion}}
|
|
* org.opencontainers.image.revision = {{commitFullHash}}
|
|
|
|
You may use any xref:configuration:name-templates.adoc[] as part of the label value.
|
|
|
|
== Generic Image Names
|
|
|
|
Some users might want to keep their image name as generic as possible. That can be accomplished simply by adding
|
|
a template to the `imageNames` field.

This will build the following images:
|
|
|
|
* `myuser/app`
|
|
|
|
== Prerelease Image Names
|
|
|
|
A different set of images names will be automatically configured when the project is snapshot, to avoid possible clashes
|
|
with production images.
|
|
|
|
JReleaer will look for the first image name that ends with `:{{tagName}}` and discard the rest.
|
|
|
|
It will use `{{repoOwner}}/{{distributionName}}:{{tagName}}` if no matching image name is found.
|
|
|
|
== Keeping docker images updated for current major
|
|
|
|
Some users might want to when version to push docker tags `:v1`, `:v1.6`, `:v1.6.4` and `:latest` when `v1.6.4`
|
|
(for example) is built. That can be accomplished by using multiple image names:
