# XDS - X(cross) Development System Server XDS-server is a web server that allows user to remotely cross build applications. The first goal is to provide a multi-platform cross development tool with near-zero installation. The second goals is to keep application sources locally (on user's machine) to make it compatible with existing IT policies (e.g. corporate backup or SCM). This powerful webserver (written in [Go](https://golang.org)) exposes a REST interface over HTTP and also provides a Web dashboard to configure projects and execute only _(for now)_ basics commands. XDS-server also uses [Syncthing](https://syncthing.net/) tool to synchronize projects files from user machine to build server machine or container. > **NOTE**: For now, only Syncthing sharing method is supported to synchronize projects files. > **SEE ALSO**: [xds-make](https://github.com/iotbzh/xds-make), a wrapper on `make` command that allows you to build your application from command-line through xds-server. ## How to build ### Dependencies - Install and setup [Go](https://golang.org/doc/install) version 1.7 or higher to compile this tool. - Install [npm](https://www.npmjs.com/) : `sudo apt install npm` - Install [gulp](http://gulpjs.com/) : `sudo npm install -g gulp-cli` ### Building Clone this repo into your `$GOPATH/src/github.com/iotbzh` and use delivered Makefile: ```bash mkdir -p $GOPATH/src/github.com/iotbzh cd $GOPATH/src/github.com/iotbzh git clone https://github.com/iotbzh/xds-server.git cd xds-server make all ``` And to install xds-server in /usr/local/bin: ```bash make install ``` ## How to run ## Configuration xds-server configuration is driven by a JSON config file (`config.json`). Here is the logic to determine which `config.json` file will be used: 1. from command line option: `--config myConfig.json` 2. `$HOME/.xds/config.json` file 3. `<current dir>/config.json` file 4. `<xds-server executable dir>/config.json` file Supported fields in configuration file are: ```json { "webAppDir": "location of client dashboard (default: webapp/dist)", "shareRootDir": "root directory where projects will be copied", "logsDir": "directory to store logs (eg. syncthing output)", "sdkRootDir": "root directory where cross SDKs are installed", "syncthing": { "binDir": "syncthing binaries directory (default: executable directory)", "home": "syncthing home directory (usually .../syncthing-config)", "gui-address": "syncthing gui url (default http://localhost:8384)", "gui-apikey": "syncthing api-key to use (default auto-generated)" } } ``` >**NOTE:** environment variables are supported by using `${MY_VAR}` syntax. ## Start-up Use `xds-server-start.sh` script to start all requested tools ```bash /usr/local/bin/xds-server-start.sh ``` >**NOTE** you can define some environment variables to setup for example config file `XDS_CONFFILE` or change logs directory `LOGDIR`. See head section of `xds-server-start.sh` file to see all configurable variables. ## Install XDS-server in AGL SDK docker container XDS-server has been designed to easily cross compile [AGL](https://www.automotivelinux.org/) applications. That's why XDS-server is integrated in AGL SDK docker container. >**NOTE** For more info about AGL SDK docker container, please refer to [AGL SDK Quick Setup](http://docs.automotivelinux.org/docs/getting_started/en/dev/reference/setup-sdk-environment.html) ### Create XDS AGL docker worker container You can either load a pre-build docker image or rebuild this image with latest source code. * load pre-build docker image: ```bash wget http://iot.bzh/download/public/2017/XDS/docker/docker_agl_worker-xds-3.2.tar.xz | docker load ``` * OR execute following commands to rebuild docker image: ```bash git clone https://git.automotivelinux.org/AGL/docker-worker-generator cd docker-worker-generator make build FLAVOUR=xds ``` You should get `docker.automotivelinux.org/agl/worker-xds:X.Y` image ```bash docker images REPOSITORY TAG IMAGE ID CREATED SIZE docker.automotivelinux.org/agl/worker-xds 3.2 786d65b2792c 6 days ago 602MB ``` ### Start XDS AGL docker worker container Use provided script to create a new docker image and start a new container: ```bash > ./docker-worker-generator/contrib/create_container 0 docker.automotivelinux.org/agl/worker-xds:3.2 > docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES b985d81af40c docker.automotivelinux.org/agl/worker-xds:3.2 "/usr/bin/wait_for..." 6 days ago Up 4 hours 0.0.0.0:8000->8000/tcp, 0.0.0.0:69->69/udp, 0.0.0.0:10809->10809/tcp, 0.0.0.0:2222->22/tcp agl-worker-seb-laptop-0-seb ``` This container exposes following ports: - 8000 : XDS-server to serve XDS Dashboard - 69 : TFTP - 2222 : ssh Now start xds-server inside this container: ```bash > ssh -p 2222 devel@localhost [15:59:58] devel@agl-worker-seb-laptop-0-seb:~$ /usr/local/bin/xds-server-start.sh ### Configuration in config.json: { "webAppDir": "/usr/local/bin/www-xds-server", "shareRootDir": "/home/devel/.xds/share", "logsDir": "/tmp/xds-server/logs", "sdkRootDir": "/xdt/sdk", "syncthing": { "binDir": "/usr/local/bin", "home": "/home/devel/.xds/syncthing-config", "gui-address": "http://localhost:8384", "gui-apikey": "1234abcezam" } } ### Start XDS server nohup /usr/local/bin/xds-server --config /home/devel/.xds/config.json -log warn > /tmp/xds-server/logs/xds-server.log 2>&1 pid=22379 ``` You can now connect your browser to XDS-server (running by default on port 8000): [http://localhost:8000](http://localhost:8000) ## Debugging ### XDS server architecture The server part is written in *Go* and web app / dashboard (client part) in *Angular2*. ``` | +-- bin/ where xds-server binary file will be built | +-- config.json.in example of config.json file | +-- glide.yaml Go package dependency file | +-- lib/ sources of server part (Go) | +-- main.go main entry point of of Web server (Go) | +-- Makefile makefile including | +-- README.md this readme | +-- scripts/ hold various scripts used for installation or startup | +-- tools/ temporary directory to hold development tools (like glide) | +-- vendor/ temporary directory to hold Go dependencies packages | +-- webapp/ source client dashboard (Angular2 app) ``` Visual Studio Code launcher settings can be found into `.vscode/launch.json`. ## TODO: - replace makefile by build.go to make Windows build support easier - add more tests - add more documentation - add authentication / login (oauth) + HTTPS - enable syncthing user/password + HTTPS
