+# 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 goal is to keep application sources locally (on user's machine).
+ - Make it compatible with existing IT policies (e.g. corporate backup or SCM).
+ - Let user to continue to work as usual.
+ - Use his favorite editor.
+ - keep performance while editing/browsing sources.
+ - Avoids manual operation
+
+This powerful and portable webserver (written in [Go](https://golang.org))
+exposes a REST interface over HTTP.
+
+`xds-server` uses [Syncthing](https://syncthing.net/) tool to synchronize
+projects files from user machine to build server machine or container.
+
+`xds-server` is commonly running on a build server (within a container or not)
+and [xds-agent](../2_xds-agent/0_abstract.html) must run on the developer/user machine in order
+to setup the following connection chain:
+
+```schema
+ developer/user machine | build server or container
+ ---------------------------|-----------------------------
+ xds-cli <---> xds-agent <-|-> xds-server
+```
+
+**SEE ALSO**: [xds-cli](https://gerrit.automotivelinux.org/gerrit/gitweb?p=src/xds/xds-cli.git),
+a command-line tool that allows you to send commands to `xds-agent / xds-server`
+and for example build your application from command-line or from your favorite
+IDE (such as Netbeans or Visual Studio Code) through `xds-agent <=> xds-server`.

+# Configuration
+
+`xds-server` configuration is driven by a JSON config file (`server-config.json`).
+
+Here is the logic to determine which `server-config.json` file will be used:
+
+1. from command line option: `--config myConfig.json`
+1. `$HOME/.xds/server/server-config.json` file
+1. `/etc/xds/server/server-config.json` file
+1. `<xds-server executable dir>/server-config.json` file
+
+Supported fields in configuration file are:
+
+- **httpPort** : HTTP port of client webapp/REST API
+- **webAppDir** : location of client web application (default: webapp/dist)
+- **shareRootDir** : root directory where projects will be copied
+- **logsDir** : directory to store logs (eg. syncthing output)
+- **sdkScriptsDir** : directory where scripts, used to managed SDKs, are installed
+- **syncthing.binDir** : syncthing binaries directory (default: executable directory)
+- **syncthing.home"** : syncthing home directory (usually .../syncthing-config)
+- **syncthing.gui-address** : syncthing gui url (default <http://localhost:8385>)
+- **syncthing.gui-apikey** : syncthing api-key to use (default auto-generated)
+
+All fields are optional and example below corresponds to the default values.
+
+```json
+{
+ "httpPort": 8000,
+ "webAppDir": "webapp/dist",
+ "shareRootDir": "${HOME}/.xds/server/projects",
+ "logsDir": "/tmp/logs",
+ "sdkScriptsDir": "${EXEPATH}/scripts/sdks",
+ "syncthing": {
+ "binDir": "./bin",
+ "home": "${HOME}/.xds/server/syncthing-config",
+ "gui-address": "http://localhost:8385",
+ "gui-apikey": "123456789",
+ }
+}
+```
+
+>**Notes:**
+>
+>Environment variables are supported by using `${MY_VAR}` syntax.
+>
+
+When `xds-server` is started as a systemd service, default environment variables
+are set into `/etc/default/xds-server` file.
+
+`xds-server` configuration is also driven by a JSON config file (`server-config.json`),
+and default JSON config is `/etc/xds/server/server-config.json`.
+
+<!-- note -->
+**Note:**
+You can use your own JSON config by settings `APP_CONFIG` variable of
+`/etc/default/xds-server` file to your file, for example `/home/MYUSER/.xds/server/server-config.json`
+<!-- endnote -->
+
+## Disable syncthing
+
+`CloudSync` synchronization type based on `syncthing` tool can be disabled by
+simply removing (or renaming) `"syncthing"` key in configuration file.
+Here is a JSON configuration file example where syncthing key as been renamed:
+
+```json
+{
+ "httpPort": 8000,
+ "webAppDir": "webapp/dist",
+ "shareRootDir": "${HOME}/.xds/server/projects",
+ "logsDir": "/tmp/logs",
+ "sdkScriptsDir": "${EXEPATH}/scripts/sdks",
+ "syncthing_DISABLE": {
+ "binDir": "./bin",
+ "home": "${HOME}/.xds/server/syncthing-config",
+ }
+}
+```
+
+On benefit to do that is to increase XDS-Server startup time.
+
+<!-- note -->
+**Note:**
+
+- `CloudSync` (AKA syncthing) synchronization type can also be disabled when `"syncthing"` key is not defined in JSON configuration file.
+

+# How to run
+
+`xds-server` has been designed to easily compile and debug
+[AGL](https://www.automotivelinux.org/) applications. That's why `xds-server` has
+been integrated into 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)
+
+## Start xds-server within the container
+
+See [Installation based on Docker container](../../part-1/2-1_install-xds-server-docker.html)
+chapter.
+
+## Manually Start XDS server
+
+XDS server is started as a service by Systemd.
+
+```bash
+/lib/systemd/system/xds-server.service
+```
+
+This Systemd service starts a bash script
+
+```bash
+/opt/AGL/xds/server/xds-server-start.sh
+```
+
+If needed you can change default setting by defining specific environment
+variables file
+
+```bash
+ssh -t -p 2222 devel@localhost vim /etc/default/xds-server
+```
+
+For example to control log level, just set LOG_LEVEL env variable.
+
+knowing that supported *level* are:
+
+- panic
+- fatal
+- error
+- warn
+- info
+- debug
+
+```bash
+docker exec ${CONTAINER_NAME} bash -c "echo 'LOG_LEVEL=debug' >> /etc/default/xds-server"
+ssh -p 2222 devel@localhost -- "systemctl --user restart xds-server"
+```
+
+## SDK cross-toolchain Management
+
+### Setup to add support of a new SDK family
+
+<!-- note -->
+**Optional step**: read this chapter only if you plan to add a new SDK family.
+<!-- endnote -->
+
+`xds-server` dynamically detects supported SDKs by scanning sub-directories of
+`sdkScriptsDir` directory (see [Configuration chapter](1_config.html)).
+
+Each sub-directory (usually name is the same as the SDK family) of `sdkScriptsDir`
+must contain a set of scripts that will be called by `xds-server` to managed SDKs
+of a specific family.
+
+These scripts are:
+
+- `add`: used to add/install a new SDK
+- `db-dump`: returned the list of available and installed SDKs (JSON format)
+- `db-update`: update SDKs database
+- `get-family-config`: returned SDK family configuration structure (JSON format)
+- `get-sdk-info`: extract SDK info (JSON format) from a SDK file/tarball
+- `remove`: used to remove an existing SDK
+
+For example, here 2 SDKs family (`agl` and `zephyr`) are defined:
+
+```bash
+# > tree ./sdks/
+./sdks/
+├── agl
+│ ├── add
+│ ├── db-dump
+│ ├── db-update
+│ ├── get-family-config
+│ ├── get-sdk-info
+│ └── remove
+├── README.md
+└── zephyr
+ ├── add
+│ ├── db-dump
+│ ├── db-update
+│ ├── get-family-config
+│ ├── get-sdk-info
+ └── remove
+```
+
+On startup `xds-server` will call in order:
+
+- `sdks/*/get-family-config` to get configuration of each SDK family.
+- `sdks/*/db-dump` scripts to get the initial list of available and installed SDKs.
+
+Please refer to `sdks/README.md` for more information about scripts definition
+and to understand how to add support of a new SDK family.
+
+### Install a new SDK from command line
+
+Used `sdks` command of `xds-cli` tool to managed SDKs.
+
+```bash
+# List all available SDKs
+xds-cli sdks ls -a

+### Un-install a SDK from XDS Dashboard
+
+Open XDS-Dashboard in web-browser and select `SDKs` entry in left side menu.
+
+If needed, switch to `BASIC SDKS VIEW` view and click on trash icon located
+in the top-right corner of SDK card.
+
+## XDS server REST API and Web application
+
+`xds-server` exposes a REST API and serves a basic web-application.
+
+REST API based url is `http://localhost:8000/api/v1/` when XDS server is
+running on your host (localhost) and basic web-application is available at
+[http://localhost:8000](http://localhost:8000).
+
+Just replace `localhost` by the host name or ip when `xds-server` is running
+on another host.
+
+```bash
+# Get version using REST API
+curl http://localhost:8000/api/v1/version
+
+# Open browser and local xds-server web-application
+xdg-open http://localhost:8000
+```
+
+Then follow instructions provided on this page to install and start `xds-agent`
+that must run locally on your machine.
+
+See also [xds-agent documentation](../2_xds-agent/0_abstract.html) for more details.

+# Build xds-server from scratch
+
+## Dependencies
+
+Install [Go](https://golang.org/doc/install), [npm](https://www.npmjs.com/),
+[nodejs](https://nodejs.org/en/) and some other tools.
+
+Refer to [Prerequisites chapter](../1_Prerequisites.html) for more details.
+
+## Building
+
+### Native build
+
+Create a GOPATH variable(must be a full path):
+
+```bash
+export GOPATH=$(realpath ~/workspace_go)
+```
+
+Clone this repo into your `$GOPATH/src/gerrit.automotivelinux.org/gerrit/src/xds` and use delivered Makefile:
+
+```bash
+export GOPATH=${GOPATH}:${ROOTDIR}
+
+mkdir -p $ROOTDIR/src/gerrit.automotivelinux.org/gerrit/src/xds
+cd $ROOTDIR/src/gerrit.automotivelinux.org/gerrit/src/xds
+git clone https://gerrit.automotivelinux.org/gerrit/src/xds/xds-server
+# or git clone ssh://YOUR_USERNAME@gerrit.automotivelinux.org:29418/src/xds/xds-server
+cd xds-server
+make all
+```
+
+And to install `xds-server` (by default in `/opt/AGL/xds/server`):
+
+```bash
+make install
+```
+
+<!-- warning -->
+**Warning:**
+
+Makefile install rule and default values in configuration file are set
+to fit the docker setup.
+
+So you may need to adapt some settings when you want to install xds-server natively.
+<!-- endwarning -->
+
+<!-- note -->
+**Note:**
+
+Used `DESTDIR` to specify another install directory
+
+```bash
+make install DESTDIR=$HOME/opt/xds-server
+```
+
+<!-- endnote -->
+
+### XDS docker image
+
+As an alternative to a pre-build image, you can rebuild the container from scratch.
+
+`xds-server` has been integrated as a flavour of AGL SDK docker image.
+
+So to rebuild docker image just execute following commands:
+
+```bash
+# Clone docker-worker-generator git repo
+git clone https://git.automotivelinux.org/AGL/docker-worker-generator
+# Start build that will create a docker image
+cd docker-worker-generator
+make build FLAVOUR=xds
