How to Add Third-party Software into CageFS June 5, 2025

In this article, we explain how to add third-party software to CageFS because, by default, CageFS does not include third-party software.

To include it, follow these steps:

1. Create a new configuration file at:

   /etc/cagefs/conf.d/SOFTWARE_NAME.cfg

   Example: openssh-clients.cfg
   [openssh-clients]
   comment=OpenSSH Clients
   paths=/etc/ssh/ssh_config, /bin/hostname, /usr/bin/scp, /usr/bin/sftp, 
   /usr/bin/slogin, /usr/bin/ssh, /usr/bin/ssh-add, /usr/bin/ssh-agent, 
   /usr/bin/ssh-copy-id, /usr/bin/.ssh.hmac, /usr/bin/ssh-keyscan, 
   /usr/libexec/openssh/sftp-server, /etc/environment, 
   /etc/security/pam_env.conf
   devices=/dev/ptmx

2. If needed, you can customise the configuration by including additional files, users, groups, or devices.
3. Run the following commands to add the software and update CageFS:

   cagefsctl --addrpm SOFTWARE_RPM_NAME
   cagefsctl –update

In this way, you can successfully include third-party software in CageFS by creating a custom configuration and updating the environment accordingly.
