Docker Consul (Alpine)

This is a Dockerfile to set up "Hashicorp Consul" - (https://www.consul.io/).

Docker Hub

The built image is also hosted at Docker Hub - (https://hub.docker.com/r/cryptout/consul/). If you don't want to customize the container you can run it directly by typing the following commands.

export VOL_DATA="/Volumes/shares/docker/data/consul/data"
export VOL_CONFIG="/Volumes/shares/docker/config/consul/config"

docker run -d -h $(hostname) \
    -p 8300:8300 \
    -p 8301:8301 \
    -p 8301:8301/udp \
    -p 8302:8302 \
    -p 8302:8302/udp \
    -p 8400:8400 \
    -p 8500:8500 \
    -p 8600:8600 \
    -p 8600:8600/udp \
    -v ${VOL_DATA}:/consul/data \
    -v ${VOL_CONFIG}:/consul/config \
    -v /etc/localtime:/etc/timezone \
    -e PUID=1000 \
    -e PGID=1000 \
    --name=consul --restart=always cryptout/consul

Notes

I'm still learning Docker and use these private (pet)projects to develop my skills. While I use these containers myself they are by no means perfect and are always prone to error or change. That said, even if only one person copies a snippet of code or learns something from my projects I feel I've contributed a little bit to the Open-source cause...
