如何使用Terraform在多个可用区域中创建ef

Question

我已经在两个可用区中启动了两个ec2实例，我需要使用terraform在两个实例中安装ef。

resource "aws_efs_file_system" "magento-efs" {
   creation_token = "efs-demo"
   performance_mode = "generalPurpose"
   throughput_mode = "bursting"
   encrypted = "true"
 tags = {
     Name = "Magento-EFS"
   }
 }

resource "aws_efs_mount_target" "efs-mount" {
   file_system_id  = "${aws_efs_file_system.magento-efs.id}"
   subnet_id = "${aws_subnet.public_subnet.0.id}"
   security_groups = ["${aws_security_group.efs-sg.id}"]
}

使用上述代码，我可以在us-east-1a中创建efs。我需要同时在us-east-1a和us-east-1b中提供

Answer 1

您只需要在AZ us-east-1b的子网中添加另一个安装目标：

git merge

更优雅（使用resource "aws_efs_mount_target" "efs-mount-b" { file_system_id = "${aws_efs_file_system.magento-efs.id}" subnet_id = "${aws_subnet.public_subnet.1.id}" security_groups = ["${aws_security_group.efs-sg.id}"] } 取决于子网数）：

count

Answer 2

我使用 terraform 版本 0.14.10。这会奏效。

resource "aws_efs_mount_target" "efs-mount-a" {
   file_system_id  = aws_efs_file_system.magento-efs.id
   subnet_id = aws_subnet.public_subnet.0.id
   security_groups = [aws_security_group.efs-sg.id]
}

resource "aws_efs_mount_target" "efs-mount-b" {
   file_system_id  = aws_efs_file_system.magento-efs.id
   subnet_id = aws_subnet.public_subnet.1.id
   security_groups = [aws_security_group.efs-sg.id]
}
