Labels added to container images are added as annotations and labels to the created kubernetes pods. Additional labels and annotations can be added with the --annotation
and --label
cli argument. Environment variables that start with K8S_ANNOTATION_
and K8S_LABEL_
will be added as a kubernetes annotation or label as well. For example K8S_ANNOTATION_FOO
will create an annotation foo
with the value of the environment variable. Note that annotations and labels added via environment variables or cli will not be processed by kubedock if they have a specific control function. For these occasions specific environment variables and cli arguments are present.
