Ops is a tool for creating and running a [Nanos](https://github.com/nanovms/nanos) unikernel. It is used to

package, create, and run your application as a [nanos](https://github.com/nanovms/nanos) unikernel instance.

# Installation



Most users should just download the binary from the website:



## Binary install



```sh

curl https://ops.city/get.sh -sSfL | sh

```



If you don't like this option you can also download pre-made packages

for various systems [here](https://ops.city/downloads) and you can also

build from source.



## Desktop applications



Operating System | Download

---|---

macOS | Get it on macOS

Windows | Get it on Windows



## MacOS via Homebrew

Add the repo & install:

```sh

brew tap nanovms/homebrew-ops

```



```sh

brew install nanovms/ops/ops

```

See the [formula file](https://github.com/nanovms/homebrew-ops/blob/master/Formula/ops.rb) for details.

 

## Debian / Redhat:



Add a deb src:



```

sudo vi /etc/apt/sources.list.d/fury.list

```



```

deb [trusted=yes] https://apt.fury.io/nanovms/ /

```



Update your sources && install:



```

sudo apt-get update && sudo apt-get install ops

```



## Build and Install from source



Building from source is easy if you have used Go before.



This program requires GO Version 1.13.x or greater.



Installing from source follows these general steps:



Install dependencies:



```sh

make deps

```



Build:



```sh

make build

```



macOS notes:



```sh

GO111MODULE=on go build -ldflags "-w"

```



For protobufs/grpc we use https://buf.build/ .



To generate protobufs (but do not check in to vcs):



```

make generate

```



For [detailed instructions](https://nanovms.gitbook.io/ops/developer/prerequisites), please consult the documentation.



# Hello World



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.



[![asciicast](https://asciinema.org/a/256914.svg)](https://asciinema.org/a/256914)



Throw this into hi.js:



```javascript

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:



```sh

ops pkg load eyberg/node:v16.5.0 -p 8083 -n -a hi.js

```



Note: Since the node package is inside the unikernel you do not need to

install node locally to use it.



# Cloud



Want to push your app out to the cloud? No complex orchestration like

K8S is necessary. OPS pushes all the orchestration onto the cloud

provider of choice so you don't need to manage anything. Be sure to try

this out as the next step after running a hello world locally as it will

answer many questions you might have.

You can find many more pre-made packages at the public repo:

Or via the shell:



```sh

ops pkg list

```



You can also upload your own with a free account.



Languages:



Various langauge examples can be found at

[https://github.com/nanovms/ops-examples](https://github.com/nanovms/ops-examples).

In general [https://nanos.org](Nanos) supports any languages and is not

language specific.

## Daemon



OPS started out as a daemon-less cli tool to build and run unikernels

locally and to also interact with the various clouds. We will keep that

functionality as-is, however, ops can also run as a daemon locally for

software that is a composition of multiple services. The daemon expects

to have elevated privileges (currently via suid bit) in order to place

the various programs on their class c network (vs relying on user-mode).

This is not necessary for 'ops run', 'ops pkg load' or 'ops instance

create' but only for multipl services ran locally that expect to

communicate to each other vs just the host.



For now the daemon and 'ops instance create' share metadata but that is

expected to change in the future.



## Apple M1/M2 Users



The Apple M1 and M2 are ARM based. OPS is built for users primarily

deploying to x86 based servers. We now have full support for running

native ARM applications (ELFs) on M1 and M2s natively. That means

without relying on Rosetta and with full hardware acceleration.



Be aware that if you wish to deploy your applications to x86 servers

you'll need to re-build your images as x86 versus the default of arm64.



# Build a bootable image

`ops build `



# Package and run

```sh

ops run 

# or

ops run -p  

```



# Using a config file

```sh

ops run -p  -c  

```



# Use golang string interoplation in config files

To enable set `ops_render_config` to `true`. Both `${ENV_VAR}` and `$ENV_VAR` are supported.



## Example Command

```sh

ops_render_config=true ops run -p  -c  

# or

export ops_render_config=true

ops run -p  -c  

```



## Example config

```JSON

{

  "Args":[

    "--user",

    "${USER}",

    "--password",

    "$PASSWORD"

  ],

  "Dirs":["myapp/static"]

}

```



# Example config file



OPS config files are plain JSON, below is an example.



```JSON

{

  "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](https://nanovms.gitbook.io/ops/google_cloud) which

handle networking for you.



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



## Useful Ops Environment Variables



The following environment variables are available to you



* `ops_render_config` - Set to `true` to use Golang ENV var interpolation to render your JSON configs.



## 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, then you can try the nightly.

The main release can tail the nightly by many weeks sometimes.



```sh

ops version

```



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



```sh

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 complete, then it's worth opening a feature request ticket to

ideate it first before jumping into code. There might be someone already

working on the feature or plans to do something entirely different.

# Support



If you are having trouble running a particular application please feel

free to open an issue and we can take a look. In general we'll only want

to support the latest release from a given application/project, however,

if you really want/need support for something older there are paid

support plans available - contact the folks at https://nanovms.com.



If you need email support you will need to sign up for a support plan.
