Split off cli into separate binaries (#37)
* 🎨 Split off cli into separate binaries This commit splits off the cli into 3 binaries: - agent - cli - provider The provider now is a separate component that can be tested by itself and have its own lifecycle. This paves the way to a ligher c3os variant, HA support and other features that can be provided on runtime. This is working, but still there are low hanging fruit to care about. Fixes #14 * 🤖 Add provider bin to releases * ⚙️ Handle signals * ⚙️ Reduce buildsize footprint * 🎨 Scan for providers also in /system/providers * 🤖 Run goreleaser * 🎨 Refactoring

Description: `

Bootstraps a node which is started in pairing mode. It can send over a configuration file used to install the c3os node.
|
||||
|
||||
For example:
|
||||
$ c3os register --config config.yaml --device /dev/sda ~/Downloads/screenshot.png
|
||||
|
||||
will decode the QR code from ~/Downloads/screenshot.png and bootstrap the node remotely.
|
||||
|
||||
If the image is omitted, a screenshot will be taken and used to decode the QR code.
|
||||
|
||||
See also https://docs.c3os.io/installation/device_pairing/ for documentation.

Usage: "Connect to a c3os VPN network",
|

Description: `
|
||||
Starts a bridge with a c3os network or a node.
|
||||
|
||||
# With a network
|
||||
|
||||
By default, "bridge" will create a VPN network connection to the node with the token supplied, thus it requires elevated permissions in order to work.
|
||||
|
||||
For example:
|
||||
|
||||
$ sudo c3os bridge --network-token <TOKEN>
|
||||
|
||||
Will start a VPN, which local ip is fixed to 10.1.0.254 (tweakable with --address).
|
||||
|
||||
The API will also be accessible at http://127.0.0.1:8080
|
||||
|
||||
# With a node
|
||||
|
||||
"c3os bridge" can be used also to connect over to a node in recovery mode. When operating in this modality c3os bridge requires no specific permissions, indeed a tunnel
|
||||
will be created locally to connect to the machine remotely.
|
||||
|
||||
For example:
|
||||
|
||||
$ c3os bridge --qr-code-image /path/to/image.png
|
||||
|
||||
Will scan the QR code in the image and connect over. Further instructions on how to connect over will be printed out to the screen.
