Use docker to pull Elasticsearch to retrieve the image

Install the latest Elasticsearch

docker pull elasticsearch

Because elasticsearch is written in java, it occupies 2G of memory space when started by default, so we need to configure the running memory before starting

docker run -e ES_JAVA_OPTS="-Xms256m -Xmx256m"
 -d -p 9200:9200 -p 9300:9300  --name ES01 id

Where id is the IMAGE ID, check

whether the startup is successful through docker images query

docker ps

As follows (i.e. success)
