eru-cli

Installation

Release binaries

Every tag publishes stripped linux and darwin archives for amd64 and arm64, plus an unstripped linux debug build:

VERSION=$(curl -fsSL https://api.github.com/repos/projecteru2/cli/releases/latest | jq -r .tag_name)
curl -fsSL -o eru-cli.tar.gz \
  "https://github.com/projecteru2/cli/releases/download/${VERSION}/eru-cli_${VERSION#v}_Linux_x86_64.tar.gz"
tar xzf eru-cli.tar.gz eru-cli
install -m 0755 eru-cli /usr/local/bin/eru-cli
eru-cli --version

The archive name follows eru-cli_<version>_<Os>_<Arch>.tar.gz, where Os is Linux or Darwin and Arch is x86_64 or arm64. An unversioned alias, eru-cli_<Os>_<Arch>.tar.gz, always points at the latest release.

Container image

Multi-arch images (linux/amd64, linux/arm64) are published to Docker Hub and ghcr on every tag and every push to master:

docker run -it --rm --net host ghcr.io/projecteru2/cli eru-cli --eru <core-host>:5001 pod list

--net host is the simplest way to reach a core instance that listens on the host network.

From source

Go 1.27 or newer is required; the toolchain in go.mod is downloaded automatically.

git clone https://github.com/projecteru2/cli
cd cli
make build
./eru-cli --version

make build writes ./eru-cli with the version, revision and build time linked in. Set KEEP_SYMBOL=1 to keep the symbol table for debugging.

Pointing at a core

The client needs one address and, if core has authentication enabled, a username and password:

export ERU=127.0.0.1:5001
export ERU_USERNAME=eru
export ERU_PASSWORD=secret
eru-cli core info

The address may also be given per invocation with --eru. When several core instances register themselves in the same cluster, the address is only the entry point: core’s own service discovery decides which instance ultimately serves the call.
