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.
