# Using the Container
We chose Alpine as a lightweight base with a reasonably small surface area for security concerns, but with enough functionality for development, interactive debugging, and useful health, watch, and exec scripts running under Consul in the container.
We chose Alpine as a lightweight base with a reasonably small surface area for security concerns, but with enough functionality for development, interactive debugging, and useful health, watch, and exec scripts running under Consul in the container. As of Consul 0.7, the image also includes `curl` since it is so commonly used for health checks.
Consul always runs under [dumb-init](https://github.com/Yelp/dumb-init), which handles reaping zombie processes and forwards signals on to all processes running in the container. We also use [gosu](https://github.com/tianon/gosu) to run Consul as a non-root "consul" user for better security. These binaries are all built by HashiCorp and signed with our [GPG key](https://www.hashicorp.com/security.html), so you can verify the signed package used to build a given base image.
