You’re not telling me where you’re trying to install etcd-client (in a lab? on a vagrant-based cluster? On playground? ) so I’m going to guess that’s it’s on a virtual system.

Some questions:

  • Did you run apt-get update first?
  • Are you running as root?

I just tried this on a cluster built from the CKA repo’s instructions for vagrant/virtualbox, and I see the following:

root@controlplane:/home/vagrant# apt search etcd | grep client

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

  Transitional package for etcd-client and etcd-server
etcd-client/jammy-updates,jammy-security 3.3.25+dfsg-7ubuntu0.22.04.1 amd64
  highly-available key value store -- client
  client for the etcd3 API - doc
  client for etcd3 grpc-gateway v3 API - doc
  Python Etcd client library - Python3 module
  client for the etcd3 API - Python 3.x
  client for etcd3 grpc-gateway v3 API - Python 3.x

So on my system, after doing apt update, etcd-client is available for installation.

Hello Rob,

I’m using K8s playground -named: Kubernetes single-node (latest) Playground

OK, this works for me on that playground:

$ apt update
$ apt search etcd-client. # finds an install candidate
$ apt install etcd-client # works
$ type etcdctl
etcdctl is /usr/bin/etcdctl

This installs a fairly old copy of etcdctl (it’s a 3.3), but the install works fine.
