# Base Image

This project creates a container image that provides purpose agnostic functionality to all extending images.

## Features

### Tools

The following tools are available.

- `curl`

### Extensible `ENTRYPOINT`

This image provides an entrypoint script that executes other entrypoint scripts, before executing the `CMD` (if provided).  It will execute any executable `.sh` scripts added to the path described by the `CONTAINERD_ENTRYPOINT_PATH` environment variable.  It will execute them in default sort order, so the use of numerical prefixes (`00_first.sh` or `99_last.sh`) may be wise.

You may also provide an `ENTRYPOINT_EXEC` to prefix all `CMD` executions in the entrypoint.  For instance, you could use `ENTRYPOINT_EXEC=java` so container executions would always be executing `java`.

### Extensible Certificate Authority

This image detects files in the path described by the `CACERT_INSTALL_PATH` environment variable.  If a file is found, it will treat it as a certificate and add it to the trusted certificates in all supported contexts.
