How to query aws AMI from packer?

0 votes

I want to build a golden image with packer for amazon ebs.So I created an AWS AMI user on the console to get the access_key and secret_key. If I add these values in the application-server.json and start the command using:

packer build -only=amazon-ebs application-server.json

This error comes up:

Error querying AMI: AuthFailure: Credential must have exactly 5 slash-delimited elements, e.g. keyid/date/region/service/term, got 'my_key'

status code: 401, request id: d8e8359a-dfa4-47da-bf05-81c957849a6c

How do I split the key? Do I create a new instance manually before using the packer command?

How can I split the key? Should I create an instance manually before launching the packer command?

Update #1: application-server.json

Update #2: Earlier the problem was an empty space in the access_key. But Now I've got a new problem:

amazon-ebs: Error cleaning up keypair. Please delete the key manually: Build 'amazon-ebs' errored: Error creating temporary keypair: UnauthorizedOperation: You are not authorized to perform this operation. status code: 403, request id: ee8cd02a-bdd8-4987-a798-00dc1f94e8e7

To solve the keypair error I just added the user group in aws IAM and then added the policy found on packer docs:

{

  "Version": "2012-10-17",
  "Statement": [{
      "Effect": "Allow",
      "Action" : [
        "ec2:AttachVolume",
        "ec2:AuthorizeSecurityGroupIngress",
        "ec2:CopyImage",
        "ec2:CreateImage",
        "ec2:CreateKeypair",
        "ec2:CreateSecurityGroup",
        "ec2:CreateSnapshot",
        "ec2:CreateTags",
        "ec2:CreateVolume",
        "ec2:DeleteKeypair",
        "ec2:DeleteSecurityGroup",
        "ec2:DeleteSnapshot",
        "ec2:DeleteVolume",
        "ec2:DeregisterImage",
        "ec2:DescribeImageAttribute",
        "ec2:DescribeImages",
        "ec2:DescribeInstances",
        "ec2:DescribeRegions",
        "ec2:DescribeSecurityGroups",
        "ec2:DescribeSnapshots",
        "ec2:DescribeSubnets",
        "ec2:DescribeTags",
        "ec2:DescribeVolumes",
        "ec2:DetachVolume",
        "ec2:GetPasswordData",
        "ec2:ModifyImageAttribute",
        "ec2:ModifyInstanceAttribute",
        "ec2:ModifySnapshotAttribute",
        "ec2:RegisterImage",
        "ec2:RunInstances",
        "ec2:StopInstances",
        "ec2:TerminateInstances"
      ],
      "Resource" : "*"
  }]
}

This seemed to have worked for me
