请问docker环境下如何修改内存比例system_memory_high_watermark_ratio

[Maverick]

• nebula 版本：2.5
• 部署方式：docker

docke环境下，我修改了system_memory_high_watermark_ratio为0.95后，重启了docker-compose又恢复为0.8了。请问我该如何操作呢？docker实在苦手

您好，在 compose 的yaml里，找到 graphd 的 command: 加上一行 --system_memory_high_watermark_ratio=0.95 哈

老铁，修改完了该怎么重启服务啊？啥命令？我用docker compose down和up ，结果这个值又变回0.8了

[wey]

这个例子我只改了一个 graphd，实际上应该改三个，再执行 docker-compose up -d 就好了

$ vim docker-compose.yaml
$ git diff | cat
diff --git a/docker-compose.yaml b/docker-compose.yaml
index b706435..8e945a3 100644

Compose does not use swarm mode to deploy services to multiple nodes in a swarm. All containers will be scheduled on the current node.

To deploy your application across the swarm, use `docker stack deploy`.

原来docker-compose down不需要执行啊

[wey]

嗯嗯，是的哈。
