Packer 动态源重复工件

  • 772

以下打包文件应该根据 ubuntu-versions 变量为不同的 ubuntu 版本生成单个或多个 ami。

packer {
  required_plugins {
    amazon = {
      version = ">= 0.0.2"
      source  = "github.com/hashicorp/amazon"
    }
  }
}

variable "region" {
  default     = "us-east-1"
  type        = string
  description = "A region in which to do the build"
}

variable "regions" {
  default     = ["us-east-1"]
  type        = list(string)
  description = "A list of regions to copy the AMI to."
}

variable "ubuntu-versions" {
  default     = ["18.04", "20.04"]
  type        = list(string)
  description = "Ubuntu version"
}


source "amazon-ebs" "ubuntu-generic" {
}

build {
  name = "ami-builds"
  dynamic "source" {
    for_each = var.ubuntu-versions
    labels   = ["amazon-ebs.ubuntu-generic"]
    content {
      name = "${source.value}"
      skip_create_ami         = false
      ami_name                = "Base hvm ${source.value} {{timestamp}}"
      ami_virtualization_type = "hvm"
      ami_regions             = "${var.regions}"
      instance_type = "m5.large"
      region        = "${var.region}"
      source_ami_filter {
        filters = {
          name                = "ubuntu/images/hvm-ssd/ubuntu-*-${source.value}-amd64-server-*"
          root-device-type    = "ebs"
          virtualization-type = "hvm"
        }
        most_recent = true
        owners      = ["099720109477"]
      }
      ssh_username = "ubuntu"
    }
  }

  post-processor "shell-local" {
    inline = ["echo hello"]
  }
}

它按预期运行，但我注意到加壳器重复了由于 shell 本地后处理器而产生的工件数量。打包器输出示例：

ami-builds.amazon-ebs.18.04: output will be in this color.
ami-builds.amazon-ebs.20.04: output will be in this color.

==> Wait completed after 4 minutes 29 seconds

==> Builds finished. The artifacts of successful builds are:
--> ami-builds.amazon-ebs.18.04: AMIs were created:

--> ami-builds.amazon-ebs.18.04: AMIs were created:

--> ami-builds.amazon-ebs.20.04: AMIs were created:

--> ami-builds.amazon-ebs.20.04: AMIs were created:
us-east-1: ami-0ff2caa45b3b4c0dd

如您所见，ami-021f569184d752422 和 ami-0ff2caa45b3b4c0dd 被报告了两次。没有后处理器，就不会有重复。怎么会？

    Apost-processor根据先前的工件创建额外的工件。如果您不需要额外的工件，但确实希望在构建期间在工件内执行 shell 命令，那么您实际上需要该provisioner块：

    provisioner "shell-local" {
  inline = ["echo hello"]
}
