v0.40.0 Unstable Pre-Release

We are revising and standardizing our handling of security groups and security group rules across all our Terraform modules. This is an early attempt with significant breaking changes. We will make further breaking changes soon, so using this version is not recommended.

BREAKING CHANGES

If there is something not documented here, please let us know by filing a ticket.

• var.allowed_security_groups is removed in favor of the security group module's var.security_group_rules which can contain a single source_security_group_id per rule

• var.allowed_cidr_blocks is removed in favor of the security group module's var.security_group_rules which can contain a cidr_blocks

• var.use_existing_security_groups is replaced with var.security_group_enabled (note that if the former was true, the latter should be false)

• var.existing_security_groups is replaced with var.security_groups

• security group has moved

  terraform state mv \
    "module.redis.aws_security_group.default[0]" \
    "module.redis.module.security_group.aws_security_group.default[0]"

• default security_group_rules does not allow ingress but this can be added manually.

  Note: The list must have the same json keys per index

  security_group_rules = [
    {
      type                     = "egress"
      from_port                = 0
      to_port                  = 65535
      protocol                 = "-1"
      cidr_blocks              = ["0.0.0.0/0"]
      source_security_group_id = null
      description              = "Allow all outbound traffic"
    },
    {
      type                     = "ingress"
      from_port                = 6379
      to_port                  = 6379
      protocol                 = "tcp"
      cidr_blocks              = []
      source_security_group_id = local.security_group_id # provide existing security group or comment out this rule
      description              = "Allow inbound traffic from existing Security Groups"
    },
    {
      type                     = "ingress"
      from_port                = 6379
      to_port                  = 6379
      protocol                 = "tcp"
      cidr_blocks              = [] # provide cidr blocks or comment out this rule
      source_security_group_id = null
      description              = "Allow inbound traffic from CIDR blocks"
    }
  ]

• security group rules have been moved

  Note: since the new security group rule names are generated upon a plan, the plan will need to be run first to generate the new names in order to move the rules. Replace someguid with the appropriate value.

  terraform state mv \
    'module.redis.aws_security_group_rule.egress[0]' \
    'module.redis.module.security_group.aws_security_group_rule.default["egress--1-0-65535-someguid"]'
  terraform state mv \
    'module.redis.aws_security_group_rule.ingress_security_groups[0]' \
    'module.redis.module.security_group.aws_security_group_rule.default["ingress-tcp-6379-6379-someguid"]'
  terraform state mv \
    'module.redis.aws_security_group_rule.ingress_cidr_blocks[0]' \
    'module.redis.module.security_group.aws_security_group_rule.default["ingress-tcp-6379-6379-someguid"]'
