For the wide range of CentOS compatible setups with dnf and rpm as buzzwords, we now have CentOS support for such a client added.
First setup a link to the download repository:
dnf config-manager --add-repo https://nexus.myocastor.de/repository/bintra_rpm/bintra.repo
If the command config-manager is not known you have to install some dnf plugins first and try again:
dnf install dnf-plugins-core
With that new repo added you can install the latest bintra CentOS client:
dnf --nogpgcheck install bintra
PS: The package is already gpg signed, adding the public key to your local system first will be better.
Configuring the personal JWT token is then mandatory and is done in /etc/dnf/plugins/bintra.conf which is created on installation.
