configuration using Docker image under Ubuntu ElasticSearch, cannot be started

Environment:
Ubuntu Server 16.04.1 LTS 32-bit
java version "1.8.0mm 172"

docker pull elasticsearch:5.3.1

command to get elasticsearch image,

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx265m" -d -p 9200:9200 -p 9300:9300 --name ES_5.3.1_01 elasticsearch:5.3.1

command to run the container, start the log:

standard_init_linux.go:178: exec user process caused "exec format error"

I wonder if 32-bit Ubuntu systems are not supported
