Installing XDS server

Depending of your configuration, this step is necessary or not.

In other words you are a developer and plan to use/connect to an existing xds-server running on your local network (On-Premise config) or in the Cloud (SaaS config), you don’t need to install the server part and you can skip this step.

For others (standalone config or administrators that want to install an On-Premise solution) xds-server must be installed.

Several installation types are supported :

Installation based on Docker container

Prerequisites

Docker is installed on the host machine, please refer to Docker documentation for more details.

Get the container

Load the pre-build AGL SDK docker image including xds-server:

seb@laptop ~$ wget -O - http://iot.bzh/download/public/2017/XDS/docker/docker_agl_worker-xds-latest.tar.xz | docker load

You should get docker.automotivelinux.org/agl/worker-xds:X.Y image

# List image that we just load
seb@laptop ~$ docker images "docker.automotivelinux.org/agl/worker-xds*"

docker.automotivelinux.org/agl/worker-xds       4.0              786d65b2792c        6 days ago          654MB

Create and start a new container

Use provided script to create a new docker container and start it:

# Get script
seb@laptop ~$ wget https://raw.githubusercontent.com/iotbzh/xds-server/master/scripts/xds-docker-create-container.sh

# Create new XDS worker container
seb@laptop ~$ bash ./xds-docker-create-container.sh

# Check that new container is running
seb@laptop ~$ docker ps | grep worker-xds

b985d81af40c        docker.automotivelinux.org/agl/worker-xds:3.99.1       "/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-xds-seb@laptop-0-seb

Note that you can also add a new shared directory using --volume option in order to use for example with Path-Mapping folder type.

# Create new XDS worker container and share extra '$HOME/my-workspace' directory
seb@laptop ~$ bash ./xds-docker-create-container.sh --volume /my-workspace:$HOME/my-workspace

Check if xds-server is running

xds-server is automatically started as a service on container startup.

To check if xds-server is correctly install and running, you can access the web interface, what we call the “Dashboard”, using a web browser :

# if container is running on your local host
# (else replace localhost by the name or the ip of the machine running the container)
seb@laptop ~$ xdg-open http://localhost:8000

xds-server is now up and running, you can now install AGL SDKs, please refer to chapter named “Installing AGL SDKs”

Container settings

This container (ID=0) exposes following ports:

• 8000 : xds-server to serve XDS Dashboard
• 69 : TFTP
• 2222 : ssh

This container also creates the following volumes (sharing directories between inside and outside docker):

Please refer to part 2 - xds-server documentation for additional info.

Installation based on VirtualBox appliance

coming soon …

Native installation

You can chose to install xds-server ‘natively’ instead of within a docker container but only Linux host OSes are supported and tested for native installation !

Install packages for debian distro type

# 'DISTRO' can be set to { xUbuntu_16.04, xUbuntu_16.10, xUbuntu_17.04, Debian_8.0, Debian_9.0}
seb@laptop ~$  export DISTRO="xUbuntu_16.04"

seb@laptop ~$  wget -O - http://download.opensuse.org/repositories/isv:/LinuxAutomotive:/app-Development/${DISTRO}/Release.key | sudo apt-key add -
seb@laptop ~$  sudo bash -c "cat >> /etc/apt/sources.list.d/AGL.list <<EOF
deb http://download.opensuse.org/repositories/isv:/LinuxAutomotive:/app-Development/${DISTRO}/ ./
EOF"

seb@laptop ~$  sudo apt-get update
seb@laptop ~$  sudo apt-get install agl-xds-server

Install packages for openSUSE distro type

# DISTRO can be set to {openSUSE_Leap_42.2, openSUSE_Leap_42.3, openSUSE_Tumbleweed}
seb@laptop ~$  export DISTRO="openSUSE_Leap_42.2"

seb@laptop ~$  sudo zypper ar http://download.opensuse.org/repositories/isv:/LinuxAutomotive:/app-Development/${DISTRO}/isv:LinuxAutomotive:app-Development.repo

seb@laptop ~$  sudo zypper ref
seb@laptop ~$  sudo zypper install agl-xds-server

Configure xds-server

Optional step: nothing to do if you keep default settings

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 (config.json), and default JSON config is /etc/xds-server/config.json.

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/config.json

Supported fields in JSON configuration file are :

• httpPort : HTTP port of client webapp / dashboard
• 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)
• 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:

{
    "httpPort": 8000,
    "webAppDir": "webapp/dist",
    "shareRootDir": "${HOME}/.xds-server/projects",
    "logsDir": "/tmp/logs",
    "sdkRootDir": "/xdt/sdk",
    "syncthing": {
        "binDir": "./bin",
        "home": "${HOME}/.xds-server/syncthing-config",
        "gui-address": "http://localhost:8385",
        "gui-apikey": "123456789",
    }
}

Note: environment variables are supported by using ${MY_VAR} syntax.

Start/Stop xds-server

xds-server can be managed as a systemd service with the following commands:

# Status XDS server:
seb@laptop ~$ systemctl --user status xds-server.service

# Stop XDS server
seb@laptop ~$ systemctl --user stop xds-server.service

# Start XDS server
seb@laptop ~$ systemctl --user start xds-server.service

# Get XDS server logs
seb@laptop ~$ systemctl --user --unit=xds-server.service --output=cat

To check if xds-server is correctly install and running, you can access the web interface, what we call the “Dashboard”, using a web browser :

seb@laptop ~$ xdg-open http://localhost:8000
