How to create FreeNAS Jails with iocage

by

Here are the steps to create a FreeNAS jail using iocage:

  1. Install iocage: iocage is included in FreeNAS 11.3 and later versions. To verify that iocage is installed, run the following command:
    iocage --version
  2. Create a Jail: To create a jail, run the following command:
    iocage create -r 11.3-RELEASE ip4_addr="em0|192.168.1.100/24" host_hostname="jail1"

    This will create a jail with the IP address 192.168.1.100 and hostname jail1 running the 11.3-RELEASE version of FreeBSD. Replace em0 with the name of the network interface you want to assign the jail IP address to.

  3. Start the Jail: After the jail is created, start it using the following command:
    iocage start jail1
  4. Login to the Jail: To login to the jail, run the following command:
    iocage console jail1
  5. Install Packages: You can install packages in the jail using the standard package management tools, such as pkg or portsnap.

These are the basic steps to create a FreeNAS jail using iocage. You can use iocage to manage multiple jails on a FreeNAS system, each running a different version of FreeBSD with its own set of packages and configuration.
