Currently confd ships binaries for OS X and Linux 64bit systems. You can download the latest release from GitHub
$ wget https://github.com/bacongobbler/confd/releases/download/v0.12.1/confd-0.12.1-darwin-amd64
$ wget https://github.com/bacongobbler/confd/releases/download/v0.12.1/confd-0.12.1-linux-amd64
$ ./build
$ sudo ./install
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 ./build
The above docker commands will produce binary in the local bin directory.
Get up and running with the Quick Start Guide.
