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<br> host OS | Start-up | Install instructions | +|-------------------|-------------------------|---------------------------------------------------|----------------------| +| Docker container | Linux or MacOS | Automatic based on systemd user service | [see Installation based on Docker container](../../part-1/1-1_install-xds-server-docker.html) | +| Virtual Machine | Linux, MacOS or Windows | Automatic based on systemd user service | [see Installation based on VirtualBox appliance](../../part-1/1-2_install-xds-server-vm.html) | +| Native | Linux | Automatic based on systemd user service or manual | [see Native installation](../../part-1/1-3_install-xds-server-native.html) | +| Native | MacOS or Windows | Manually | [see Native installation](../../part-1/1-3_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 +``` + +<!-- section-note --> +**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. + +<!-- end-section-note --> + +## 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. + +## SDK cross-toolchain Management + +### Setup to add support of a new SDK family + +<!-- section-note --> +**Optional step**: read this chapter only if you plan to add a new SDK family. +<!-- end-section-note --> + +`xds-server` dynamically detects supported SDKs by scanning sub-directories of +`sdkScriptsDir` directory (see [Configuration chapter](2_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](2_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 + +Please refer to [Installing AGL SDKs](../../part-1/3_install-sdks.html) chapter. + +### 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
