Etcd installation

Why?

1. minimal or no requirements to start
2. does not require root privileges
3. run etcd instances on my laptop
4. does not require docker or virtual machnne(s)

Download

Go to etcd releases page etcd/releases and decide wich version you want. Bare in mind that the order of versions on that page is kind of random. You can search for “Latest release” tag to find the latest and greatest version.

Modify below two variables to whatever you want them to be. Both variables will be used in following steps (!).

export ETCD_VER=v3.2.24
export ETCD_INSTALL_DIR=${HOME}/etcd

Download desirable version

GOOGLE_URL=https://storage.googleapis.com/etcd
DOWNLOAD_URL=${GOOGLE_URL}

rm -f  ${ETCD_INSTALL_DIR}/etcd-${ETCD_VER}-linux-amd64.tar.gz
rm -rf ${ETCD_INSTALL_DIR} && mkdir -p ${ETCD_INSTALL_DIR}

curl -L ${DOWNLOAD_URL}/${ETCD_VER}/etcd-${ETCD_VER}-linux-amd64.tar.gz \
     -o ${ETCD_INSTALL_DIR}/etcd-${ETCD_VER}-linux-amd64.tar.gz

Installation

Installation may not be the best word in this place. I basically extract pre-compiled etcd version to $ETCD_INSTALL_DIR directory.

tar xzvf ${ETCD_INSTALL_DIR}/etcd-${ETCD_VER}-linux-amd64.tar.gz \
    -C ${ETCD_INSTALL_DIR} --strip-components=1
rm -f ${ETCD_INSTALL_DIR}/etcd-${ETCD_VER}-linux-amd64.tar.gz

Start etcd

This is standalone instance, no clustering.

${ETCD_INSTALL_DIR}/etcd \
    --name etcd0 \
    --listen-client-urls http://localhost:2379 \
    --advertise-client-urls  http://localhost:2379

Test your etcd

This is standalone instance, no clustering.

alias etcdctl="ETCDCTL_API=3 ${ETCD_INSTALL_DIR}/etcdctl --endpoints http://localhost:2379"

etcdctl version
etcdctl cluster-health
etcdctl member list
etcdctl put foo bar
etcdctl get foo
etcdctl check perf
