The Initializ Buildpack for Image Labels is a Cloud Native Buildpack that enables configuration of labels on the created images.
buildpack allows for the configuration of both OCI-specified labels with short environment variable names, as well as arbitrary labels using a space-delimited syntax in a single environment variable.
This buildpack will participate if any of the following conditions are met
$BP_IMAGE_LABELSis set$BP_OCI_AUTHORSis set$BP_OCI_CREATEDis set$BP_OCI_DESCRIPTIONis set$BP_OCI_DOCUMENTATIONis set$BP_OCI_LICENSESis set$BP_OCI_REF_NAMEis set$BP_OCI_REVISIONis set$BP_OCI_SOURCEis set$BP_OCI_TITLEis set$BP_OCI_URLis set$BP_OCI_VENDORis set$BP_OCI_VERSIONis set
The buildpack will do the following:
- If
$BP_IMAGE_LABELSis set, it will split the value first along=, respecting quotes and set each of the pairs as image labels - If
$BP_OCI_AUTHORSis set, it will set the value as theorg.opencontainers.image.authorsimage label - If
$BP_OCI_CREATEDis set, it will set the value as theorg.opencontainers.image.createdimage label - If
$BP_OCI_DESCRIPTIONis set, it will set the value as theorg.opencontainers.image.descriptionimage lable - If
$BP_OCI_DOCUMENTATIONis set, it will set the value as theorg.opencontainers.image.documentationimage label - If
$BP_OCI_LICENSESis set, it will set the value as theorg.opencontainers.image.licensesimage label - If
$BP_OCI_REF_NAMEis set, it will set the value as theorg.opencontainers.image.ref.nameimage label - If
