Podman pitfalls

Fedora docs are your friend

SELinux might be on

If you are having permission denied errors watch out for SELinux. Check your podman VM and verify /etc/selinux/config . You can consider switching to permissive mode + reboot

Certificate errors

MITM

Some company like to or must inspect their users traffic. Generally this is done by having a transparent proxy which terminates SSL/TLS and uses a self-signed certificate that is owned by the company and can be considered trusted. The default podman VM won´t trust this certificate. You can try the following:

COPY the PEM file to /etc/pki/ca-trust/source/anchors/ and then update the trust:

update-ca-trust force-enable && update-ca-trust extract

Time drift

If the podman VM has time drift this can also break SSL/TLS certificate verification. Just update the time of your VM.

Allow docker in podman

sudo rpm-ostree install podman-docker
