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:
var http = require('http');
http.createServer(function (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 load node_v11.5.0 -p 8083 -f -n -a hi.js

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
get the release channel (or nightly)
ls .ops/
if using a package
get the package hash:
cat .ops/packages/manifest.json| jq '."gnatsd_1.4.1"'
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.
Security
Feel free to email security at.
