Consul Template powered Nginx container.
This container is not intended to be used by itself. You have to create a container which inherits this. E.g., with a configuration template app.conf.ctmpl Dockerfile would be:
FROM yanana/nginx-consul-template
ADD app.conf.ctmpl /etc/consul-templates/app.conf.ctmpl
CMD ["my_init"]
And the template:
upstream app {
least_conn;
{{range service "some-cool-app"}}server {{.Address}}:{{.Port}} max_fails=3 fail_timeout=60 weight=1;
{{else}}server 127.0.0.1:65535; # force a 502{{end}}
}
And given running docker-consul container named 'consul':
docker run -d \
-v /somewhere/to/put/logs:/var/log/nginx:rw \
--link consul:consul \
-p port-to-publish-nginx:80 \
--name container-name \
-e "SERVICE_NAME=service-name-to-register-to-consul" \
-e "SERVICE_TAGS=tag1,tag2,tag3" \
