Installing Rancher HA using rke

Please use High Availability (HA) Install 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.

RKE now fetches data.json from https://github.com/rancher/kontainer-driver-metadata. To fetch data.json and compile it in rke, run

go generate

# Change RANCHER_METADATA_URL to an external URL instead of using https://releases.rancher.com/kontainer-driver-metadata/dev-v2.4/data.json by default
RANCHER_METADATA_URL=${URL} go generate

# Or load it from local file
RANCHER_METATDATA_URL=./local/data.json go generate

# Compile RKE
make

To specify RANCHER_METADATA_URL in 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]

RANCHER_METADATA_URL defaults to https://releases.rancher.com/kontainer-driver-metadata/dev-v2.4/data.json.
