我正在使用Postdock在Postgres主从之间进行负载平衡。 PostDock
我提取了最新版本的github存储库并运行docker-compose -f ./docker-compose/latest.yml up -d pgmaster pgslave1 pgslave2 pgslave3 pgslave4 pgpool backup
首先，pgpool容器处于启动状态，pgmaster和4个从属处于运行状态。但是几分钟后，主服务器关闭，然后其他容器关闭。
您能帮我解决这个问题吗？谢谢！

答案 0 :(得分：0)
我找到了解决方案。需要为每个节点配置环境变量（节点名称，REPLICATION_PRIMARY_HOST。BACKEND）！
