|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|

represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain

separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.

|
||||
this License, each Contributor hereby grants to You a perpetual,

|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|

||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You

||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work

|
||||
|
||||
WebVM is a server-less virtual environment running fully client-side in HTML5/WebAssembly. It's designed to be Linux ABI-compatible. It runs an unmodified Debian distribution including many native development toolchains.
|
||||
|
||||
WebVM is powered by the CheerpX virtualization engine, and enables safe, sandboxed client-side execution of x86 binaries on any browser. CheerpX includes an x86-to-WebAssembly JIT compiler, a virtual block-based file system, and a Linux syscall emulator.
|
||||
|
||||
# Enable networking
|
||||
# How to: general usage
|
||||
|
||||
Modern browsers do not provide APIs to directly use TCP or UDP. WebVM provides networking support by integrating with Tailscale, a VPN network that supports WebSockets as a transport layer.
|
||||
- go to [https://webvm.io](https://webvm.io)
|
||||
- use the provided terminal environment
|
||||
- have fun!
|
||||
|
||||
- Open the "Networking" panel from the side-bar
|
||||
- Click "Connect to Tailscale" from the panel
|
||||
- Log in to Tailscale (create an account if you don't have one)
|
||||
- Click "Connect" when prompted by Tailscale
|
||||
- If you are unfamiliar with Tailscale or would like additional information see [WebVM and Tailscale](/docs/Tailscale.md).
|
||||
# How to: enable networking
|
||||
|
||||
# Fork, deploy, customize
|
||||
- go to [https://webvm.io](https://webvm.io)
|
||||
- click "Tailscale Login" in the top right corner
|
||||
- log in to Tailscale (create an accout if you don't have one)
|
||||
- if you want to access the public internet, you need an Exit Node. See [here](https://tailscale.com/kb/1103/exit-nodes/) for how to set one up. If you just want to access a machine in your Tailscale Network, you don't need it
|
||||
- depending on your network speed, you may need to wait a few moments for the Tailscale Wasm module to be downloaded
|
||||
- log in with your Tailscale credentials
|
||||
- go back to the WebVM tab. You will see your IP address in the top right
|
||||
- start firing network requests!

# How to: login to Tailscale with an Auth key
|
||||
|
||||
- Fork the repository.
|
||||
- Enable Github pages in settings.
|
||||
- Click on `Settings`.
|
||||
- Go to the `Pages` section.
|
||||
- Select `Github Actions` as the source.
|
||||
- If you are using a custom domain, ensure `Enforce HTTPS` is enabled.
|
||||
- Run the workflow.
|
||||
- Click on `Actions`.
|
||||
- Accept the prompt. This is required only once to enable Actions for your fork.
|
||||
- Click on the workflow named `Deploy`.
|
||||
- Click `Run workflow` and then once more `Run workflow` in the menu.
|
||||
- After a few seconds a new `Deploy` workflow will start, click on it to see details.
|
||||
- After the workflow completes, which takes a few minutes, it will show the URL below the `deploy_to_github_pages` job.
|
||||
- Add `#authKey=<your-key>` at the end of the URL
|
||||
- Done. You don't need to manually log in anymore
|
||||
|
||||
<img src="/assets/result.png" width="70%" >
|
||||
It is recommended to use an ephemeral key.
|
||||
|
||||
You can now customize `dockerfiles/debian_mini` to suit your needs, or make a new Dockerfile from scratch. Use the `Path to Dockerfile` workflow parameter to select it.

|
||||
# Local deployment
|
||||
|
||||
From a local `git clone`
|
||||
|
||||
- Download the `debian_mini` Ext2 image from [https://github.com/leaningtech/webvm/releases/](https://github.com/leaningtech/webvm/releases/)
|
||||
- You can also build your own by selecting the "Upload GitHub release" workflow option
|
||||
- Place the image in the repository root folder
|
||||
- Edit `config_github_terminal.js`
|
||||
- Uncomment the default values for `CMD`, `ARGS`, `ENV` and `CWD`
|
||||
- Replace `IMAGE_URL` with the URL (absolute or relative) for the Ext2 image. For example `"/debian_mini_20230519_5022088024.ext2"`
|
||||
- Build WebVM using `npm`, output will be placed in the `build` directory
|
||||
- `npm install`
|
||||
- `npm run build`
|
||||
- Start NGINX, it automatically points to the `build` directory just created
|
||||
- `nginx -p . -c nginx.conf`
|
||||
- Visit `http://127.0.0.1:8081` and enjoy your local WebVM
|
||||
|
||||
# Example customization: Python3 REPL
|
||||
|
||||
The `Deploy` workflow takes into account the `CMD` specified in the Dockerfile. To build a REPL you can simply apply this patch and deploy.

||||
|
||||
```diff
|
||||

# Enable networking
|
||||
|
||||
- In order to access the public internet, you will need an Exit Node. See [Tailscale Exit Nodes](https://tailscale.com/kb/1103/exit-nodes/) for detailed instructions.
|
||||
- ***Note:*** This is not required to access machines in your own Tailscale Network.
|
||||
- Depending on your network speed, you may need to wait a few moments for the Tailscale Wasm module to be downloaded.
|
||||
|
||||
**When all set:**
|
||||
- Log in with your Tailscale credentials.
|
||||
- Go back to the WebVM tab.
|
||||
- The `Connect to Tailscale` button in the Networking side-panel should be replaced by your IP address.
|
||||
|
||||
# Log in to Tailscale with an Auth key
|
||||
|
||||
- Add `#authKey=<your-key>` at the end of the URL.
|
||||
- Done, you don't need to manually log in anymore.
|
||||
|
||||
It is recommended to use an ephemeral key.
|
||||
|
||||
# Log in to a self-hosted Tailscale network (Headscale)
|
||||
|
||||
- Add `#controlUrl=<your-control-url>` at the end of the URL.
|
||||
- You can combine this option with `authKey` with a `&`: `#controlUrl=<url>&authKey=<key>`.
