# 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 There are several way to install xds-server and start-up depend of installation type: | Installation type | Supported
host OS | Start-up | Install instructions | |-------------------|-------------------------|---------------------------------------------------|----------------------| | Docker container | Linux or MacOS | Automatic based on systemd user service | [see Installation based on Docker container](../../part-1/2-1_install-xds-server-docker.html) | | Virtual Machine | Linux, MacOS or Windows | Automatic based on systemd user service | [see Installation based on VirtualBox appliance](../../part-1/2-2_install-xds-server-vm.html) | | Native | Linux | Automatic based on systemd user service or manual | [see Native installation](../../part-1/2-3_install-xds-server-native.html) | | Native | MacOS or Windows | Manually | [see Native installation](../../part-1/2-3_install-xds-server-native.html) | ### Automatic start-up based on systemd user service XDS server is started as a user service by Systemd. ```bash /usr/lib/systemd/user/xds-server.service ``` Use well-known systemd commands to control `xds-server.service` service. ```bash # Enter in docker container or VM # (optional, depending on installation type) ssh -p 2222 devel@localhost # Status XDS server: systemctl --user status xds-server # Restart XDS server systemctl --user restart xds-server ``` 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" ``` ### Manual start-up On **Linux or MacOS**, simply execute `xds-server` executable: ```bash /opt/AGL/bin/xds-server ``` On **Windows**, simply execute `xds-server` executable: ```batch C:\AGL\bin\xds-server.exe ``` **Note:** Invoke `xds-server --help` to get more details about possible options that allow for example to change logging level or select another configuration file. ## SDK cross-toolchain Management ### Setup to add support of a new SDK family **Optional step**: read this chapter only if you plan to add a new SDK family. `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-update` to update database (only when `SdkDbUpdate` is set to ̀`startup`, see [Configuration chapter](1_config.html) for more details) - `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 List of available SDKs: ID NAME STATUS VERSION ARCH ec15afe0 AGL-release-eel-4.99.4-raspberrypi3 Not Installed 4.99.4 armv7vehf-neon-vfpv4 944d2d5a AGL-snapshots-master-latest-intel-corei7-64 Not Installed 4.99.3+snapshot corei7-64 cf3a4365 AGL-release-dab-4.0.2-qemux86-64 Not Installed 4.0.2 corei7-64 d65fe750 AGL-release-eel-latest-qemux86-64 Not Installed 4.99.3 corei7-64 a0ae663d poky-agl-corei7-64-3.99.1+snapshot Installed 3.99.1+snapshot corei7-64 87f0400b AGL-release-dab-3.99.3-m3ulcb-nogfx Installed 3.99.3 aarch64 8c2f2841 AGL-release-dab-4.0.2-dragonboard-410c Not Installed 4.0.2 aarch64 ... # Install a SDK (downloaded + install) xds-cli sdks install d65fe750 Installation of 'AGL-release-eel-latest-qemux86-64' SDK successfully started.

Each time you wish to use the SDK in a new shell session, you need to source the environment setup script e.g. $ . /xdt/sdk/poky-agl/5.0.0/corei7-64/environment-setup-corei7-64-agl-linux SDK ID d65fe750-d3a7-38f5-83d8-3d3806054f8d successfully installed. # Abort an installation that is in progress xds-cli sdks abort -id d65fe750 # Install a SDK (using a local SDK package/file) xds-cli sdks install --file $HOME/xds-workspace/sdks/poky-agl-glibc-x86_64-agl-demo-platform-crosssdk-corei7-64-toolchain-5.0.0.sh ``` Installation based on a local SDK package is only supported when SDK file package is located in `$HOME/xds-workspace/sdks` directory ### Install a new SDK from XDS Dashboard Open XDS-Dashboard in web-browser and select `SDKs` entry in left side menu. Then switch to `SDKs MANAGEMENT` view : ![](../part-1/pictures/xds-dashboard-sdks-mgt.png){:: style="margin:auto; display:flex"} Use filter boxes to find the SDK you want to install and then click on plus icon (Actions column) to start installation. SDK download and installation process may take several minutes and output of installation script (output of `add` script mentioned in above chapter). ![](../part-1/pictures/xds-dashboard-sdks-install.png){:: style="margin:auto; display:flex"} Note that you can abort installation by clicking on `CANCEL` button. ### Un-install a SDK from command line Used `sdks` command of `xds-cli` tool to managed SDKs. ```bash # List installed SDKs xds-cli sdks ls List of installed SDKs: ID NAME STATUS VERSION ARCH c39e5998 poky-agl_aarch64_4.0.1 Installed 4.0.1 aarch64 d610bfbf poky-agl-aarch64.current_on_iotbzh_download-3.99.1+snapshot Installed 3.99.1+snapshot aarch64.current_on_iotbzh_download a0ae663d poky-agl-corei7-64-3.99.1+snapshot Installed 3.99.1+snapshot corei7-64 87f0400b AGL-release-dab-3.99.3-m3ulcb-nogfx Installed 3.99.3 aarch64 352c0584 poky-agl-corei7-64-3.99.2+snapshot Installed 3.99.2+snapshot corei7-64 d65fe750 AGL-release-eel-latest-qemux86-64 Installed 4.99.5 corei7-64 # Un-install a SDK xds-cli sdks uninstall d65fe750 SDK ID d65fe750-d3a7-38f5-83d8-3d3806054f8d successfully deleted. ``` ### 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.
