如何将安全组应用到 aws_elasticache_replication_group
how to apply security groups to aws_elasticache_replication_group
我的 terraform 脚本如下: VPC 中的所有内容
resource "aws_security_group" "cacheSecurityGroup" {
name = "${var.devname}-${var.namespace}-${var.stage}-RedisCache-SecurityGroup"
vpc_id = var.vpc.vpc_id
tags = var.default_tags
ingress {
protocol = "tcp"
from_port = 6379
to_port = 6379
cidr_blocks = ["0.0.0.0/0"]
ipv6_cidr_blocks = ["::/0"]
}
egress {
protocol = "-1"
from_port = 0
to_port = 0
cidr_blocks = ["0.0.0.0/0"]
ipv6_cidr_blocks = ["::/0"]
}
}
resource "aws_elasticache_parameter_group" "usagemonitorCacheParameterGroup" {
name = "${var.devname}${var.namespace}${var.stage}-usagemonitor-cache-parameterGroup"
family = "redis6.x"
}
resource "aws_elasticache_subnet_group" "redis_subnet_group" {
name = "${var.devname}${var.namespace}${var.stage}-usagemonitor-cache-subnetGroup"
subnet_ids = var.vpc.database_subnets
}
resource "aws_elasticache_replication_group" "replication_group_usagemonitor" {
replication_group_id = "${var.devname}${var.namespace}${var.stage}-usagemonitor-cache"
replication_group_description = "Replication group for Usagemonitor"
node_type = "cache.t2.micro"
number_cache_clusters = 2
parameter_group_name = aws_elasticache_parameter_group.usagemonitorCacheParameterGroup.name
subnet_group_name = aws_elasticache_subnet_group.redis_subnet_group.name
#security_group_names = [aws_elasticache_security_group.bar.name]
automatic_failover_enabled = true
at_rest_encryption_enabled = true
port = 6379
}
如果我取消注释该行
#security_group_names = [aws_elasticache_security_group.bar.name]

我收到以下错误:
Error: Error creating Elasticache Replication Group: InvalidParameterCombination: Use of cache security groups is not permitted along with cache subnet group and/or security group Ids.
status code: 400, request id: 4e70e86d-b868-45b3-a1d2-88ab652dc85e
我读到如果所有资源都在 VPC 中,我们不必使用 aws_elasticache_security_group。将安全组分配给 aws_elasticache_replication_group 的正确方法是什么??? usinf 子网???怎么样???
我这样做了,我相信这是分配所需配置的最佳方式:
resource "aws_security_group" "redis" {
name_prefix = "${var.name_prefix}-redis-"
vpc_id = var.vpc_id
lifecycle {
create_before_destroy = true
}
}
resource "aws_elasticache_replication_group" "redis" {
...
engine = "redis"
subnet_group_name = aws_elasticache_subnet_group.redis.name
security_group_ids = concat(var.security_group_ids, [aws_security_group.redis.id])
}
您的子网组基本上包括所有私有或 public 来自将要创建 elasticache 复制组的 VPC 的子网。
一般情况下,使用安全组 ID 而不是名称。
我已经编写了一个绝对有效的 terraform 模块,如果您有兴趣,可以在示例 https://github.com/umotif-public/terraform-aws-elasticache-redis.
