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]
