Questions tagged [consul-template]

Consul template renders Go templates based on data queried from HashiCorp Consul.

Consul template is a simple, yet powerful tool. When initiated, it reads one or more template files and queries Consul for all data needed to render them. Typically, you run consul-template as a daemon which will fetch the initial values and then continue to watch for updates, re-rendering the template whenever there are relevant changes in the cluster.

The tag should be used for tool specific questions like daemon setup or usage of provided template functions. More general Go template questions should be tagged with instead.
