ops
currently support?A: Currently, nanos can run on both qemu and xen . We are obviously open to adding more support for other various hypervisors but there are considerations to be had.
Also - Nanos runs on Google Cloud && AWS.
A: We track latest qemu in homebrew as we have found issues before. The latest qemu release is currently 6.0.X. If you don't have that release try to install from brew:
A: Sure! We accept pull requests and if you have prior kernel experience please get in touch with NanoVMs - they might even want to pay you.
ops
produce?A: ops
builds a disk image artifact that you can find in ~/.ops/images. . You can get a list of all your images via:
This disk image is ran by qemu
to execute your application.
ops
inside a container?A: Yes, it is possible to run ops
within a container such as docker. Although, it is NOT recommended to do so, especially for production environments. You will likely run into performance related issues.
A: We consider this an anti-pattern of software development and a scourge on the software ecosystem. It is advised to utilize your native language API and libraries to achieve the task instead.
A: Nanos currently makes use of the TFS filesystem and can run databases and other things through the POSIX api you all know.
ops
on a cloud provider with bridged networking?A: We do not suggest running ops on a cloud provider on top of linux. We suggest using the native way of provisioning your unikernels so they run by themselves standalone and you won't have do any network configuration.
Please see the following cloud documentation for whichever cloud provider you wish to run on:
ops net setup
A: This is only necessary if you wish to create your own bridges and attach tap interfaces to them. It's not a task we suggest most people do though.
A: This can work with kubernetes but kubernetes is a container orchestrator and is typically deployed on top of an existing virtual machine whereas the intention for these are to run as virtual machines. Further, kubernetes has very serious security issues that should be considered such as sharing a kernel amongst multiple tenants.
You can use the Uname syscall and extract the sysname from it:
Please see for running Nanos under kubernetes.
Yes, if you are coding in Go you can use the API found at .
If you are looking for a web-accessible API has you covered.
