Hello!
I have 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

But when I try the same with ubi7-init based container (or rhel7-init):
$ cat Containerfile
FROM registry.access.redhat.com/ubi7/ubi-init
RUN echo -e
"[repo1]\nname=repo1\nbaseurl=http://repos.example.com/RHEL-7/7.9/Server/x86_64/os/\ngpgcheck=0\nenabled=1"
>/etc/yum.repos.d/repo1.repo; yum -y install httpd; yum clean all; systemctl enable
httpd
EXPOSE 80
CMD [ "/sbin/init" ]
it fails:
$ sudo podman run -ti -p 80:80
d872b16b8d0f9718c60420e3569cb4d5ddd16053fb72903e70d7b62ba3f34964
Failed to mount cgroup at /sys/fs/cgroup/systemd: Operation not permitted
[!!!!!!] Failed to mount API filesystems, freezing.
And same with privileged:
$ sudo podman run -ti -p 80:80 --privileged=true
d872b16b8d0f9718c60420e3569cb4d5ddd16053fb72903e70d7b62ba3f34964
Failed to mount cgroup at /sys/fs/cgroup/systemd: Operation not permitted
[!!!!!!] Failed to mount API filesystems, freezing.
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
Please, any idea on what I'm doing wrong?
Thank you in advance and happy new year!
Regards,
Jan
