tarantool - 如何自动配置 Tarantool Cartridge 集群？

Question

我有一个在 Tarantool Cartridge 上开发的应用程序。我的集群由 12 个 Tarantool 实例组成，分为 4 个副本集（一些是路由器，一些是存储）。现在开始从头开始设置这个集群，我在 Web UI 管理应用程序上手动配置这个集群：创建副本集、引导存储、配置故障转移模式。如何自动进行此配置？什么是最好的方法？

Answer 1

有这样的工具：

• Ansible 角色：https ://github.com/tarantool/ansible-cartridge
• Kubernetes 算子：https ://github.com/tarantool/tarantool-operator

Answer 2

您可以启动应该包含在集群中的所有 tarantool 实例，通过 tarantoolctl 连接到其中一个并执行确定集群拓扑的脚本，通过 vshard 初始化分片，并配置故障转移模式（在示例中，通过 etcd）。

cartridge = require('cartridge')
replicasets = { {
                    alias = 'router1',
                    roles = { 'router', 'vshard-router', 'failover-coordinator' },
                    join_servers = { { uri = '172.20.0.2:3301' } }
                }, {
                    alias = 'router2',
                    roles = { 'router', 'vshard-router', 'failover-coordinator' },
                    join_servers = { { uri = '172.20.0.3:3301' } }
                }, {
                    alias = 'router3',
                    roles = { 'router', 'vshard-router', 'failover-coordinator' },
                    join_servers = { { uri = '172.20.0.4:3301' } }
                }, {
                    alias = 'storage1',
                    roles = { 'storage', 'vshard-storage' },
                    join_servers = { { uri = '172.20.0.2:3302' },
                                     { uri = '172.20.0.3:3302' },
                                     { uri = '172.20.0.4:3302' } }
                }, {
                    alias = 'storage2',
                    roles = { 'storage', 'vshard-storage' },
                    join_servers = { { uri = '172.20.0.3:3303' },
                                     { uri = '172.20.0.2:3303' },
                                     { uri = '172.20.0.4:3303' } }
                }, {
                    alias = 'storage3',
                    roles = { 'storage', 'vshard-storage' },
                    join_servers = { { uri = '172.20.0.4:3304' },
                                     { uri = '172.20.0.2:3304' },
                                     { uri = '172.20.0.3:3304' } }
                } }

cartridge.admin_edit_topology({ replicasets = replicasets })
cartridge.admin_bootstrap_vshard()
cartridge.failover_set_params({
    mode = 'stateful',
    state_provider = 'etcd2',
    etcd2_params = {
        prefix = '/',
        lock_delay = 10,
        endpoints = { '172.20.0.2:2379', '172.20.0.3:2379', '172.20.0.4:2379' }
    }
})
