# 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..."

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 user 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) Please refer to [xds-server configuration](../part-2/1_xds-server/1_config.html) chapter for additional info about xds-server settings.
