A new environment variable RKE_ADMISSION_CONFIG_CHECKSUM whose value is the checksum of the content of the admission configuration file is added to the env list that is set in the `kube-apiserver` container configuration, so any changes in the admission configuration file will result in a change in the container's configuration. RKE will detect the changes during reconciliation and therefore restart the kube-apiserver container on all CP nodes. The upgrade cadence is thresholded by the upgrade strategy in the cluster. This PR also drops the unnecessary appending of env var to the cluster object which shows in the cluster.rkestate file. Signed-off-by: Jiaqi Luo <6218999+jiaqiluo@users.noreply.github.com> |

This file is auto-generated from README-template.md, please make any changes there.
Rancher Kubernetes Engine, an extremely simple, lightning fast Kubernetes installer that works everywhere.
Latest Release
Download
Please check the releases page.
Requirements
Please review the Requirements for each node in your Kubernetes cluster.
Getting Started
Please refer to our RKE docs for information on how to get started! For cluster config examples, refer to RKE cluster.yml examples
Installing Rancher HA using rke
Please use Setting up a High-availability RKE Kubernetes Cluster to install Rancher in a high-availability configuration.
Building
RKE can be built using the make command, and will use the scripts in the scripts directory as subcommands. The default subcommand is ci and will use scripts/ci. Cross compiling can be enabled by setting the environment variable CROSS=1. The compiled binaries can be found in the build/bin directory. Dependencies are managed by Go modules and can be found in go.mod.
Read codegen/codegen.go to check the default location for fetching data.json. You can override the default location as seen in the example below:
# Fetch data.json from default location
go generate
# Fetch data.json from URL using RANCHER_METADATA_URL
RANCHER_METADATA_URL=${URL} go generate
# Use data.json from local file
RANCHER_METATDATA_URL=./local/data.json go generate
# Compile RKE
make
To override RANCHER_METADATA_URL at runtime, populate the environment variable when running rke CLI. For example:
RANCHER_METADATA_URL=${URL} rke [commands] [options]
RANCHER_METADATA_URL=${./local/data.json} rke [commands] [options]
