Change to ENTRYPOINT + CMD & exec "${@}" mechanism

[niek-sidn]

Change to ENTRYPOINT + CMD & exec "${@}" mechanism in dockerfiles and entrypoints.

e.g.
Dockerfile:

COPY --chmod=755 entrypoints/entrypoint_bind.sh /entrypoint.sh
ENTRYPOINT ["/entrypoint.sh"]
CMD ["/usr/sbin/named","-c","/etc/bind/named.conf","-f","-g"]

Entrypoint:

#!/usr/bin/env bash
exec "${@}"

Looks like this is the best way to prevent:

• Data corruption during shutdown
• Unnecessary delay in stopping containers
• Incomplete cleanup operations
