AWS ECS MongoDB Error: Node primary did not become available

Question

错误：

Node mongodb-primary.ecs.endpoint did not become available

详情：

我已经使用 https://github.com/bitnami/bitnami-docker-mongodb 作为具有副本集功能的 Docker 映像在 AWS ECS 上部署了 MongoDB，这意味着我在同一个服务器上还有 2 个服务运行除了主实例之外的 EC2 实例是次要实例和仲裁实例。

部署后，所有 3 个服务都会启动它们的任务，并且主要服务的任务保持运行成功，而次要服务和仲裁服务的任务失败。

这是日志：

有人知道如何解决这个问题吗？

Answer 1

问题：

缺少副本集配置。

解法：

为了解决这个问题，我使用 MongoDB Compass 登录到主实例，然后使用 mongosh 到运行以下命令：rs.initiate()。一分钟之内，其他节点（辅助节点和仲裁节点）将自己注册到副本集中，主节点成为主节点。

输出：

下面是 rs.status() 命令的日志：

结论：

在 AWS ECS 上创建 MongoDB 集群后，使用默认或具有所有节点端点的自定义配置启动副本集。
