#!/bin/bash ########################################## # WARNING WARNING WARNING WARNING # # This script is an example to start a new AGL XDS container # # You should customize it to fit your environment and in particular # adjust the paths and permissions where needed. # # Note that sharing volumes with host system is not mandatory: it # was just added for performances reasons: building from a SSD is # just faster than using the container filesystem: that's why /xdt is # mounted from there. Same applies to ~/mirror and ~/share, which are # just 2 convenient folders to store reference build caches (used in prepare_meta script) # ########################################## CURDIR=$(cd $(dirname $0) && pwd -P) REGISTRY=docker.automotivelinux.org REPO=agl NAME=worker FLAVOUR=xds VERSION=4.0 # --------------------------------------------------- # --- computed - don't touch ! # --------------------------------------------------- DOCKER_USER=devel DEFIMAGE=$REGISTRY/$REPO/$NAME-$FLAVOUR:$VERSION function usage() { echo "Usage: $(basename $0) [-h] [-fr] [-v] <instance ID> [image name]" >&2 echo "Instance ID must be 0 or a positive integer (1,2,...)" >&2 echo "Image name is optional: 'make show-image' is used by default to get image" >&2 echo "Default image: $DEFIMAGE" >&2 echo "" echo "Options:" echo " -fr | --force-restart Force restart of xds-server service" echo " -nuu | --no-uid-update Don't update user/group id within docker" echo " -v | --volume Additional docker volume to bind, syntax is -v /InDockerPath:/HostPath " exit 1 } ID="" IMAGE="" FORCE_RESTART=false UPDATE_UID=true USER_VOLUME_OPTION="" while [ $# -ne 0 ]; do case $1 in -h|--help|"") usage ;; -fr|--force-restart) FORCE_RESTART=true ;; -nuu|--no-uid-update) UPDATE_UID=false ;; -v|--volume) shift if [[ "$1" =~ .*:.* ]]; then USER_VOLUME_OPTION="-v $1" else echo "Invalid volume option, format must be /InDockerPath:/hostPath" exit 1 fi ;; *) if [[ "$1" =~ ^[0-9]+$ ]]; then ID=$1 else IMAGE=$1 fi ;; esac shift done [ "$ID" = "" ] && ID=0 # Dynamically retrieve image name if [ "$IMAGE" = "" ]; then VER_NUM=`docker images $REGISTRY/$REPO/$NAME-$FLAVOUR:* --format {{.Tag}} | wc -l` if [ $VER_NUM -gt 1 ]; then echo "ERROR: more than one xds image found, please set explicitly the image to use !" exit 1 elif [ $VER_NUM -lt 1 ]; then echo "ERROR: cannot automatically retrieve image tag for $REGISTRY/$REPO/$NAME-$FLAVOUR" exit 1 fi VERSION=`docker images $REGISTRY/$REPO/$NAME-$FLAVOUR:* --format {{.Tag}}` if [ "$VERSION" = "" ]; then echo "ERROR: cannot automatically retrieve image tag for $REGISTRY/$REPO/$NAME-$FLAVOUR" usage exit 1 fi IMAGE=$REGISTRY/$REPO/$NAME-$FLAVOUR:$VERSION fi USER=$(id -un) echo "Using instance ID #$ID (user $(id -un))" NAME=agl-xds-$(hostname|cut -f1 -d'.')-$ID-$USER docker ps -a |grep "$NAME" > /dev/null [ "$?" = "0" ] && { echo "Image name already exist !
