# we define an environment variable with the location of our Consul cluster. By default, it will try to resolve to
# consul:8500 which would be the behavior if we have Consul running as a container in the same host and we link it to this
# KairosDB container (with the alias consul, of course). But this environment variable can also be overridden when we run the
# container if we want to point somewhere else.

ENV        CONSUL_URL consul:8500

# download the latest version of Consul Template and we put it on /usr/local/bin

ADD        https://releases.hashicorp.com/consul-template/${CONSUL_TEMPLATE_VERSION}/consul-template_${CONSUL_TEMPLATE_VERSION}_linux_amd64.zip /usr/bin/

# we define a volume /templates, which is where we will mount our template files from the host. This way we can reuse
# the same image for different services and templates.

VOLUME     /templates

# our container will expose ports 4242 and 8080, where KairosDB will be running
