2.错误原因分析

2-1 启动ES容器命令

docker run -d \
    --name es \
    -e "ES_JAVA_OPTS=-Xms1024m -Xmx1024m" \
    -e "discovery.type=single-node" \
    -v es-data:/usr/share/elasticsearch/data \
    -v es-plugins:/usr/share/elasticsearch/plugins \
    --privileged \
    --network es-net \
    -p 9200:9200 \
    -p 9300:9300 \
elasticsearch:7.16.1

2-2 错误分析（使用gpt3.5查询分析的，如果错误，恳请指正）

1.errno=12：错误码为12，表示内存不足（OOM）

2."ES_JAVA_OPTS=-Xms1024m -Xmx1024m"分析该命令：
ES_JAVA_OPTS环境变量可以用来设置JVM的参数，以便控制JVM在容器中使用的内存量。该命令中 -Xms1024m指定JVM堆的最小内存量为1024MB， -Xmx1024m指定JVM堆的最大内存量为1024MB。
这样设置JVM堆内存可以避免Elasticsearch使用太多内存导致OOM（Out of Memory）错误。如果Elasticsearch需要更多的内存来执行操作，JVM内存将会自动增长到最大值，但是如果超过最大值，将会抛出OOM错误

3.也就是说JVM占用内存过多，减少JVM占用内存即可，-Xms1024m指定JVM堆的最小内存量为1024MB，通过将设置的JVM最小内存量调整为512M来减少JVM占用的内存，将问题得以解决

3.解决

 docker run -d \
    --name es \
    -e "ES_JAVA_OPTS=-Xms512m -Xmx1024m" \
    -e "discovery.type=single-node" \
    -v es-data:/usr/share/elasticsearch/data \
    -v es-plugins:/usr/share/elasticsearch/plugins \
    --privileged \
    --network es-net \
    -p 9200:9200 \
    -p 9300:9300 \
elasticsearch:7.16.1

运行容器成功：
