Addon-manager
addon-manager manages two classes of addons with given template files in
$ADDON_PATH
(default /etc/kubernetes/addons/
).
- Addons with label
addonmanager.kubernetes.io/mode=Reconcile
will be periodically reconciled. Direct manipulation to these addons through apiserver is discouraged because addon-manager will bring them back to the original state. In particular:- Addon will be re-created if it is deleted.
- Addon will be reconfigured to the state given by the supplied fields in the template file periodically.
- Addon will be deleted when its manifest file is deleted from the
$ADDON_PATH
.
- Addons with label
addonmanager.kubernetes.io/mode=EnsureExists
will be checked for existence only. Users can edit these addons as they want. In particular:- Addon will only be created/re-created with the given template file when there is no instance of the resource with that name.
- Addon will not be deleted when the manifest file is deleted from the
$ADDON_PATH
.
Notes:
- Label
kubernetes.io/cluster-service=true
is deprecated (only for Addon Manager). In future release (after one year), Addon Manager may not respect it anymore. Addons have this label but withoutaddonmanager.kubernetes.io/mode=EnsureExists
will be treated as "reconcile class addons" for now. - Resources under
$ADDON_PATH
need to have either one of these two labels. Meanwhile namespaced resources need to be inkube-system
namespace. Otherwise it will be omitted. - The above label and namespace rule does not stand for
/opt/namespace.yaml
and resources under/etc/kubernetes/admission-controls/
. addon-manager will attempt to create them regardless during startup.
How to release
The addon-manager
is built for multiple architectures.
- Change something in the source
- Bump
VERSION
in theMakefile
- Bump
KUBECTL_VERSION
in theMakefile
if required - Build the
amd64
image and test it on a cluster - Push all images
# Build for linux/amd64 (default)
$ make push ARCH=amd64
# ---> gcr.io/google-containers/kube-addon-manager-amd64:VERSION
# ---> gcr.io/google-containers/kube-addon-manager:VERSION (image with backwards-compatible naming)
$ make push ARCH=arm
# ---> gcr.io/google-containers/kube-addon-manager-arm:VERSION
$ make push ARCH=arm64
# ---> gcr.io/google-containers/kube-addon-manager-arm64:VERSION
$ make push ARCH=ppc64le
# ---> gcr.io/google-containers/kube-addon-manager-ppc64le:VERSION
$ make push ARCH=s390x
# ---> gcr.io/google-containers/kube-addon-manager-s390x:VERSION
If you don't want to push the images, run make
or make build
instead
