OS containers will require more than just the application you want sandboxed. This is true for Solaris Zones, FreeBSD Jail, Linux OpenVZ or LXC (Linux Containers). And that&#x27;s fine because the concept is akin to running a VM across a shared kernel rather than abstracting the hardware via a hypervisor. So you&#x27;re effectively chrooting a sub-OS inside the host.<p>As for your comments regarding Solaris, I was using Solaris Zones about a decade ago and, inversely to your experience, I found the whole process really easy. In fact it was on Solaris where I first learned about OS containers and which really convinced me to adopt them to many other projects over the years since.<p>To be honest, it is really weird reading your comment as my experiences couldn&#x27;t differ more. If your memory is up to the job, I&#x27;d be curious to read more detail about the issues you had.
