Upgrading cert-manager
|
|
======================
|
|
|
|
This section contains information on upgrading cert-manager.
|
|
It also contains documents detailing breaking changes between cert-manager
|
|
versions, and information on things to look out for when upgrading.
|
|
|
|
.. note::
|
|
Before performing upgrades of cert-manager, it is advised to take a backup
|
|
of all your cert-manager resources just in case an issue occurs whilst
|
|
upgrading. You can read how to backup and restore cert-manager in the
|
|
:doc:`../backup-restore-crds` guide.
|
|
|
|
Upgrading with Helm
|
|
===================
|
|
|
|
If you installed cert-manager using Helm, you can easily upgrade using the Helm
|
|
CLI.
|
|
|
|
.. note::
|
|
Before upgrading, please read the relevant instructions at the links below
|
|
for your from and to version.
|
|
|
|
Once you have read the relevant upgrading notes and taken any appropriate
|
|
actions, you can begin the upgrade process like so - replacing
|
|
``<release_name>`` with the name of your Helm release for cert-manager (usually
|
|
this is ``cert-manager``) and replacing ``<version>`` with the
|
|
version number you want to install:
|
|
|
|
.. code:: shell
|
|
|
|
# Install the cert-manager CustomResourceDefinition resources before
|
|
# upgrading the Helm chart
|
|
kubectl apply \
|
|
-f https://raw.githubusercontent.com/jetstack/cert-manager/<version>/deploy/manifests/00-crds.yaml
|
|
|
|
# Add the Jetstack Helm repository if you haven't already
|
|
helm repo add jetstack https://charts.jetstack.io
|
|
|
|
# Ensure the local Helm chart repository cache is up to date
|
|
helm repo update
|
|
|
|
helm upgrade --version <version> <release_name> jetstack/cert-manager
|
|
|
|
This will upgrade you to the latest version of cert-manager, as listed in the
|
|
`Jetstack Helm chart repository`_.
|
|
|
|
.. note::
|
|
You can find out your release name using ``helm list | grep cert-manager``.
|
|
|
|
Upgrading using static manifests
|
|
================================
|
|
|
|
If you installed cert-manager using the static deployment manifests published
|
|
on each release, you can upgrade them in a similar way to how you first
|
|
installed them.
|
|
|
|
.. note::
|
|
Before upgrading, please read the relevant instructions at the links below
|
|
for your from and to version.
|
|
|
|
Once you have read the relevant notes and taken any appropriate actions, you
|
|
can begin the upgrade process like so - replacing ``<version>`` with the
|
|
version number you want to install:
|
|
|
|
.. code:: shell
|
|
|
|
kubectl apply \
|
|
-f https://github.com/jetstack/cert-manager/releases/download/<version>/cert-manager.yaml
|
|
|
|
.. note::
|
|
If you are running kubectl v1.12 or below, you will need to add the
|
|
``--validate=false`` flag to your ``kubectl apply`` command above else you
|
|
will receive a validation error relating to the ``caBundle`` field of the
|
|
``ValidatingWebhookConfiguration`` resource.
|
|
This issue is resolved in Kubernetes 1.13 onwards. More details can be found
|
|
in `kubernetes/kubernetes#69590`_.
