# 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:

| Install type | Supported OS | Section to refer |
|--------------|--------------|------------------|
| Container | Linux or MacOS | [see Installation based on Docker container](#installation-based-on-docker-container) |
| Virtual Machine | Linux, MacOS or Windows | [see Installation based on VirtualBox appliance](#installation-based-on-virtual-machine-appliance) |
| Native | Linux | [see Native installation](#native-installation) |

## Installation based on Docker container

### Docker container prerequisites

Docker is installed on the host machine, please refer to [Docker documentation](https://docs.docker.com/engine/installation/) for more details.

### Get the container

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

```bash
wget -O - http://iot.bzh/download/public/XDS/docker/docker_agl_worker-xds-latest.tar.xz | docker load
```

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

```bash
# List image that we just load
docker images "docker.automotivelinux.org/agl/worker-xds*"

REPOSITORY                                  TAG                 IMAGE ID            CREATED             SIZE
docker.automotivelinux.org/agl/worker-xds   5.0                 877979e534ff        3 hours ago         106MB
```

### Create and start a new container

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

```bash
# Get script
wget -O xds-docker-create-container.sh 'https://gerrit.automotivelinux.org/gerrit/gitweb?p=src/xds/xds-server.git;a=blob_plain;f=scripts/xds-docker-create-container.sh;hb=master'

# Create new XDS worker container
bash ./xds-docker-create-container.sh

# Check that new container is running
docker ps | grep worker-xds
f67079db4339        docker.automotivelinux.org/agl/worker-xds:5.0   "/usr/bin/wait_for..."   About a minute ago   Up 34 seconds       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-HOSTNAME-0-USERNAME
```

This container exposes following ports:

| Port number | Description                                 |
|-------------|---------------------------------------------|
|     8000    | `xds-server`: serve XDS webapp and REST API |
|      69     | TFTP                                        |
|     2222    | ssh                                         |

This container also creates the following volumes (shared folders between
inside and outside docker):

| Directory on host | Directory inside docker | Comment |
|-------------------|-------------------------|---------|
| $HOME/xds-workspace | /home/devel/xds-workspace | XDS projects workspace location|
| $HOME/xds-workspace/.xdt_0 | /xdt | location to store SDKs |
| $USER_VOLUME | $USER_VOLUME | user path, see `--volume` option of `xds-docker-create-container.sh` script |

<!-- note -->
**Note:**

You can add a new shared directory using `--volume` option in order
to use for example with Path-Mapping folder type.

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

You can change docker used port with `-id` option

```bash
# Create new XDS worker container with a different port number
bash ./xds-docker-create-container.sh -id ${ID}

# Check that new container is running
docker ps | grep worker-xds
f67079db4339        docker.automotivelinux.org/agl/worker-xds:5.0   "/usr/bin/wait_for..."   About a minute ago   Up 34 seconds       0.0.0.0:(2222+ID)->22/tcp, 0.0.0.0:(69+ID)->69/udp, 0.0.0.0:(8000+ID)->8000/tcp, 0.0.0.0:(10809+ID)->10809/tcp   agl-xds-HOSTNAME-ID-USERNAME
```

<!-- endnote -->

#### Manually setup docker user id

<!-- note -->
**Note:**

If you used `xds-docker-create-container.sh` script to create XDS
docker container, user uid/gid inside docker has already been changed by this script.
<!-- endnote -->

If you plan to use **path-mapping sharing type for your projects**, you need to
have the same user id and group id inside and outside docker.

By default user and group name inside docker is set `devel` (id `1664`).

Use following commands to replace id `1664` with your user/group id:

```bash
# Set docker container name to use (usually agl-xds-xxx where xxx is USERNAME@MACHINENAME-IDX-NAME)
export CONTAINER_NAME=agl-xds-seb@laptop-0-seb
docker ps | grep -q ${CONTAINER_NAME} || echo "ERROR: No container name \"${CONTAINER_NAME}\" please set a valid CONTAINER_NAME before you continue"

# First kill all processes of devel user (including running xds-server)
docker exec ${CONTAINER_NAME} bash -c "/bin/loginctl kill-user devel"

# Change user and group id inside docker to match your ids
docker exec ${CONTAINER_NAME} bash -c "usermod -u $(id -u) devel"
docker exec ${CONTAINER_NAME} bash -c "groupmod -g $(id -g) devel"

# Update some files ownership
docker exec ${CONTAINER_NAME} bash -c "chown -R devel:devel /home/devel /tmp/xds*"

# Restart devel autologin service
docker exec ${CONTAINER_NAME} bash -c "systemctl restart autologin"

# Restart xds-server as a service (ssh port 2222 may depend on your container ID)
ssh -p 2222 devel@localhost -- "systemctl --user restart xds-server"
```

### Check if xds-server is running (open XDS webapp)

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

If the container is running on your localhost, you can access to a basic web
application:

```bash
xdg-open http://localhost:8000
```

If needed you can status / stop / start  it manually using following commands:

```bash
# Status XDS server:
ssh -p 2222 devel@localhost systemctl --user status xds-server.service

# Stop XDS server
ssh -p 2222 devel@localhost systemctl --user stop xds-server.service

# Start XDS server
ssh -p 2222 devel@localhost systemctl --user start xds-server.service

# Get XDS server logs
ssh -p 2222 devel@localhost journalctl --user --unit=xds-server.service --output=cat
```

`xds-server` is now up and running, you can now install AGL SDKs, please refer
to next chapter named [Installing AGL SDKs](3_install-sdks.html#installing-agl-sdks)

<!-- note -->
Please refer to [part 2 - xds-server](../part-2/1_xds-server.html#sdk-cross-toolchain-management) documentation
for additional info.
<!-- endnote -->

## Installation based on Virtual Machine appliance

### Virtual Machine appliance prerequisites

> VirtualBox is installed on the host machine

please refer to [VirtualBox documentation](https://www.virtualbox.org/wiki/Downloads) for more details.

### Get the appliance

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

```bash
wget http://iot.bzh/download/public/XDS/appliance/xds-vm-debian9_latest.ova
```

### Clean old appliance

You must have one and one xds appliance only.

So, first remove the oldest xds appliance if needed.

```bash
# Get the virtual machine name
VDS_VMNAME=$(VBoxManage list vms | grep xds-vm-debian | cut -d "\"" -f2)
echo ${VDS_VMNAME}

# Remove old XDS appliance
[ -n ${VDS_VMNAME} ] && VBoxManage controlvm ${VDS_VMNAME} poweroff
[ -n ${VDS_VMNAME} ] && VBoxManage unregistervm ${VDS_VMNAME} --delete
```

### Create and start a new appliance

Used provided script to create a new appliance or you can use VirtualBox GUI:

```bash
# Import image into VirtualBox
VBoxManage import ./xds-vm-debian9_latest.ova

# Check import result
VDS_VMNAME=$(VBoxManage list vms | grep xds-vm-debian | cut -d "\"" -f2)
echo ${VDS_VMNAME}

# Start XDS appliance
[ -n ${VDS_VMNAME} ] && VBoxManage startvm ${VDS_VMNAME}
```

**Mandatory**:

Add share folder to appliance, to allow files sharing using pathmap method:

```bash
# Create local share folder
mkdir -p $HOME/xds-workspace

#Add share folder to appliance
vboxmanage sharedfolder add ${VDS_VMNAME} --name XDS-workspace --hostpath $HOME/xds-workspace
```

### Appliance settings

This image exposes following network ports (NAT mode):

- 8000 : `xds-server` to serve XDS basic web page
- 69   : TFTP
- 2222 : ssh

## 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 basic web page that gives you some instructions:

```bash
# if container/appliance is running on your local host
# (else replace localhost by the name or the ip of the machine running the container)
xdg-open http://localhost:8000
```

`xds-server` is now up and running, you can now install AGL SDKs, please refer
to next chapter named [Installing AGL SDKs](3_install-sdks.html#installing-agl-sdks)

## Native installation

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

### Install packages for debian distro type

```bash
# 'DISTRO' can be set to { xUbuntu_16.04, xUbuntu_16.10, xUbuntu_17.04, Debian_8.0, Debian_9.0}
export DISTRO="xUbuntu_16.04"

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

sudo apt-get update
sudo apt-get install agl-xds-server
```

### Install packages for openSUSE distro type

```bash
# DISTRO can be set to {openSUSE_Leap_42.2, openSUSE_Leap_42.3, openSUSE_Tumbleweed}
export DISTRO="openSUSE_Leap_42.2"

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

sudo zypper ref
sudo zypper install agl-xds-server
```

### Configure xds-server

<!-- note -->
**Optional step**: skip this chapter if you plan to use default settings
<!-- endnote -->

Please refer to [Configuration chapter of xds-server](../part-2/1_xds-server.html#configuration)
documentation for more details about JSON configuration file.

### Start/Stop xds-server

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

```bash
# Status XDS server:
systemctl --user status xds-server.service

# Stop XDS server
systemctl --user stop xds-server.service

# Start XDS server
systemctl --user start xds-server.service

# Get XDS server logs
systemctl --user --unit=xds-server.service --output=cat
```

To check if xds-server is correctly install and running, you can access the web
interface, using a web browser :

```bash
xdg-open http://localhost:8000
```

or get the current version using the following curl command:

```bash
curl http://localhost:8000/api/v1/version
```
