README
# packer-provisioner-deno
Run Deno scripts to provision stuff with Packer.
This plugin installs deno on the target machine, runs `deno bundle` locally,
uploads the bundled scripts onto the target machine, and executes them.
## Installation
This provisioner is a Packer plugin. [See the docs for an overview](https://www.packer.io/docs/extending/plugins.html#installing-plugins).
Build or download this plugin and place in
```
$HOME/.packer.d/plugins
```
You may need to create the plugins directory.
## Provisioner Configuration
You must specify `"type": "deno"` in a provisioners stanza to use this plugin.
The following provisioner config keys are supported. See also the **examples** directory.
* `local_deno_bin` (string) - A fully qualified path to a local deno executable. This
binary will be used for local bundling and uploaded to the target `remote_folder`.
Useful if you are building deno from source. Other version specifiers ignored.
* `target_deno_version` (string) - a version passed to the deno installer script.
Must match a git tag from deno's [releases](https://github.com/denoland/deno/releases).
* `remote_folder` (string) - The target directory where `scripts` will be uploaded.
* `skip_install` (boolean) - If `true`, do not install Deno on the target machine, but
assume it is already present.
* `scripts` (array of string) - A list of paths to TypeScript files that will be
passed to `deno run -A`, one by one, in order. These are your provisioning scripts.
Currently, these must be standalone scripts with no path-based dependencies.
## Development and Tests
You will need Go 1.13 or later. **$GOPATH/bin** should be on your PATH.
If you want to hack, make a symlink from **$GOPATH/bin/packer-provisioner-deno**
to the packer plugins directory. Something like this should work, after an
initial `go install`:
```
ln -s $GOPATH/bin/packer-provisioner-deno $HOME/.packer.d/plugins/packer-provisioner-deno
```
After that, run the test script
```
./test.sh
```
A test build will run in a Docker container.
## TODO
We want to accomplish the following
- [x] Install deno onto target system
- [x] Upload individual deno scripts
- [x] Execute individual deno scripts as root
- [x] Add a DigitalOcean cloud builder test
- [x] Allow uploading local deno builds easily (for testing local dev builds)
- [x] Manually bundle scripts locally and upload those.
- [ ] Execute scripts as non-root user
- [ ] Specify sandboxing flags in the packer config (`--allow-net` and friends; we run with `-A` right now)
- [ ] Global system install of deno outside any user's HOME
- [ ] Add a Vagrant builder test
- [ ] Specify alternative install command (for test deno builds fetchable from network)
