Hello! I have an issue with running "ubi7-init" based container. When I base mine container on "fedora", it works fine: $ cat Containerfile FROM fedora RUN dnf -y install httpd; dnf clean all; systemctl enable httpd EXPOSE 80 CMD [ "/sbin/init" ] and then: $ sudo podman build -f Containerfile $ sudo podman run -ti -p 80:80 20185593d0f96c4dee56e351eae4754cdd429679c1b645dae1b6f24880ce33fc systemd v246.6-3.fc33 running in system mode.

I have these versions: $ rpm -q fedora-release-common podman fedora-release-common-33-3.noarch podman-2.2.1-1.fc33.x86_64 $ sudo podman version Version: 2.2.1 API Version: 2.1.0 Go Version: go1.15.5 Built: Tue Dec 8 15:37:50 2020 OS/Arch: linux/amd64 Running very similar container on RHEL7 with docker-1.10.3-59.el7.x86_64 (there is 1.13.1 available, but have not tried) works fine. Please, any idea on what I'm doing wrong? Thank you in advance and happy new year! Regards, Jan -- Jan Hutar Performance Engineering jhutar@redhat.com Red Hat, Inc.
