make build

macOS notes:

GO111MODULE=on go build -ldflags "-w"

For detailed instructions please consult the documentation.

Basic usage examples

Before learning more about ops it is a good idea to see some basic usage examples. Below are links to simple examples using various programming platforms:

Let's run your first unikernel right now.

Throw this into hi.js:

const http = require('http');
http.createServer((req, res) => {
    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.end('Hello World\n');
}).listen(8083, "0.0.0.0");
console.log('Server running at http://127.0.0.1:8083/');

Then you can run it like so:

ops pkg load node_v11.5.0 -p 8083 -f -n -a hi.js

Apple M1 Users

The Apple M1 and M2 are ARM based. OPS is built for users primarily deploying to x86 based servers. While you can certainly run ARM builds with Nanos and OPS be aware that if you are trying to run x86 builds (the default) on ARM based M1s you won't be able to use hardware acceleration.

Build a bootable image

ops build <app>

Package and run

ops run <app>
# or
ops run -p <port> <app>

Using a config file

ops run -p <port> -c <file> <app>

Example config file

ops config files are plain JSON, below is an example

{
  "Args":["one","two"],
  "Dirs":["myapp/static"]
}

Setup networking

New users wishing to play around in a dev environment are encouraged to use the default user-mode networking. Other production users are encouraged to utilize native cloud builds such as Google Cloud which handle networking for you.

Only advanced/power users should use the bridge networking option.

Reporting Bugs

Feel free to open up a pull request. It's helpful to have your OPS version and the release channel you are using.

Also - if it doesn't work on the main release you can try the nightly - the main release can tail the nightly by many weeks sometimes.

ops version

if you are using a package, get the package hash:

jq '."gnatsd_1.4.1"' ~/.ops/packages/manifest.json

Pull Requests

If you have an idea for a new feature and it might take longer than a few hours or days to do it's worth opening a feature request tkt to ideate it first before jumping into code. There might be someone already working on the feature or plans to do something entirely different.
