Installation

Binary Download

Currently confd ships binaries for OS X and Linux 64bit systems. You can download the latest release from GitHub

OS X

$ wget https://github.com/kelseyhightower/confd/releases/download/v0.16.0/confd-0.16.0-darwin-amd64

Linux

Download the binary

$ wget https://github.com/kelseyhightower/confd/releases/download/v0.16.0/confd-0.16.0-linux-amd64

Move the binary to an installation path, make it executable, and add to path

mkdir -p /opt/confd/bin
mv confd-0.16.0-linux-amd64 /opt/confd/bin/confd
chmod +x /opt/confd/bin/confd
export PATH="$PATH:/opt/confd/bin"

Building from Source

$ make build
$ make install

Building from Source for Alpine Linux

Since many people are using Alpine Linux as their base images for Docker there's support to build Alpine package also. Naturally by using Docker itself. :)

$ docker build -t confd_builder -f Dockerfile.build.alpine .
$ docker run -ti --rm -v $(pwd):/app confd_builder make build

The above docker commands will produce binary in the local bin directory.

Build for your Image using Multi-Stage build

With multi-stage builds you can keep the whole process contained in your Dockerfile using:

FROM golang:1.9-alpine as confd

ARG CONFD_VERSION=0.16.0

ADD https://github.com/kelseyhightower/confd/archive/v${CONFD_VERSION}.tar.gz /tmp/

RUN apk add --no-cache \
    bzip2 \
    make && \
  mkdir -p /go/src/github.com/kelseyhightower/confd && \
  cd /go/src/github.com/kelseyhightower/confd && \
  tar --strip-components=1 -zxf /tmp/v${CONFD_VERSION}.tar.gz && \
  go install github.com/kelseyhightower/confd && \
  rm -rf /tmp/v${CONFD_VERSION}.tar.gz

FROM tomcat:8.5.15-jre8-alpine

COPY --from=confd /go/bin/confd /usr/local/bin/confd
