# This file defines a docker image based on Rocky Linux 9 which can be
# used for EMDIS::ECS (Perl ECS).
#
# For additional information about docker, see https://www.docker.com/
#
# Below are brief notes about using this Dockerfile.
#
# 1) Move to the directory containing this Dockerfile.
#
#    cd docker/rockylinux
#
# 2) Build a "perlecs/rockylinux" Docker image based on the Dockerfile.
#
#    docker build -t perlecs/rockylinux:0.50-1 .
#
# 3) Generate a Docker container based on the image, and run an interactive
#    bash shell within the container.
#
#    docker run --rm -it --name=perlecs_rockylinux  perlecs/rockylinux:0.50-1 /bin/bash
#
# 4) Configure Perl ECS within the docker container.  For example, use
#    "ecs_setup" to generate an ecs.cfg configuration file, "ecstool" to
#    set up the node table, "gpg" to configure the GnuPG keyring,
#    "ecs_scan_mail" to start the mail processing daemon, and "ecs_chk_com"
#    to start the communication status daemon.
#
#    For additional information about Perl ECS, try "perldoc EMDIS::ECS",
#    "perldoc EMDIS::ECS::Config", "perldoc ecstool", etc., or see the
#    EMDIS::ECS documentation on CPAN.  For additional information about
#    ECS, refer to the EMDIS and ECS specifications available from
#    http://emdis.net/.

# Note:  The gnupg1 package was removed from the EPEL repository in late
# 2025 (around 2025-11-11, when RHEL 9.7 was released).  However, the EPEL
# archive contains old versions of the gnupg1 RPM package files:
# https://dl.fedoraproject.org/pub/archive/epel/9.6-2025-11-11/
# It is recommended to verify the GPG signature of the RPM package using
# rpm --checksig to ensure its authenticity.
