默认方法启动报错：
'ERROR: [1] bootstrap checks failed
[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

解决方法一
7.0以后官方修改了启动方法：
www.elastic.co/guide/en/el…
获取镜像命令：
docker pull docker.elastic.co/elasticsearch/elasticsearch:7.4.0
启动命令：
docker run -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.4.0
默认名称是随机的可以用下面命令指定名称：
docker run --name [容器名称] -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.4.0
解决方法二
如果使用的是Kitematic操作，可以在设置中指定启动参数
discovery.type single-node
