使用 docker 的 7.7 上的 Elasticsearch 集群问题

Question

EC2 实例 1：

sudo docker run -d -p 9200:9200 -p 9300:9300 \
        -e "bootstrap.memory_lock=true" \
        -e "node.name=es01" \
        -e "network.host=172.31.139.34" \
        -e "cluster.name=docker-cluster-test" \
        -e "cluster.routing.allocation.disk.threshold_enabled=false" \
        -e "discovery.seed_hosts=172.31.135.140" \
        -e "cluster.initial_master_nodes=es01,es02" \
        -e "ES_JAVA_OPTS=-XX:UseAVX=2 -Xms1g -Xmx1g" \
        --name=elasticsearch770 \
        --ulimit nofile=65535:65535 \
        --ulimit memlock=-1:-1 \
        docker.elastic.co/elasticsearch/elasticsearch:7.7.0

EC2 实例 2：

sudo docker run -d -p 9200:9200 -p 9300:9300 \
        -e "bootstrap.memory_lock=true" \
        -e "node.name=es02" \
        -e "network.host=172.31.135.140" \
        -e "cluster.name=docker-cluster-test" \
        -e "cluster.routing.allocation.disk.threshold_enabled=false" \
        -e "discovery.seed_hosts=172.31.139.34" \
        -e "cluster.initial_master_nodes=es01,es02" \
        -e "ES_JAVA_OPTS=-XX:UseAVX=2 -Xms1g -Xmx1g" \
        --name=elasticsearch770 \
        --ulimit nofile=65535:65535 \
        --ulimit memlock=-1:-1 \
        docker.elastic.co/elasticsearch/elasticsearch:7.7.0

我遇到了问题

BindTransportException[Failed to bind to 172.31.139.34:[9300-9400]]; nested: BindException[Cannot assign requested address];

如果我设置了就不要设置network.host=172.31.135.140，继续搜索

我已通过在两个 EC2 实例的 docker 命令中添加 --network=host 来修复

sudo docker run -d -p 9200:9200 -p 9300:9300 \
        -e "bootstrap.memory_lock=true" \
        -e "node.name=es02" \
        -e "network.host=172.31.135.140" \
        -e "cluster.name=docker-cluster-test" \
        -e "cluster.routing.allocation.disk.threshold_enabled=false" \
        -e "discovery.seed_hosts=172.31.139.34" \
        -e "cluster.initial_master_nodes=es01,es02" \
        -e "ES_JAVA_OPTS=-XX:UseAVX=2 -Xms1g -Xmx1g" \
        --name=elasticsearch770 --network=host \
        --ulimit nofile=65535:65535 \
        --ulimit memlock=-1:-1 \
