As certain cloud environments enforce the tagging of resources, DKP platform users have inquired about whether it is possible to add custom tags on an AMI that was built with Konvoy Image Builder (KIB). Currently, adding a custom tag as an attribute to the AMI is only possible by modifying the packer.json file.

In order to add a tag, perform the commands below: 

  1. Generate manifest files for KIB by executing the following command. In this example, we're building a CentOS 7.9 image:

    ./konvoy-image build images/ami/centos-79.yaml
    CODE

  2. Send SIGINT to the process to kill it after seeing the output ...writing new packer configuration to work/centos-7-xxxxxxx-yyyyy. During the attempt to build the AMI a packer.json is generated under the path work/centos-7-xxxxxxx-yyyyy/packer.json.

  3.  Edit the packer.json file by adding the parameter "run_tags" to the packer.json file as seen in the example below:

     "builders": [
{
"name": "{{(user `distribution`) | lower}}-{{user `distribution_version`}}{{user `build_name_extra`}}",
"type": "amazon-ebs",
"run_tags": {"my_custom_tag": "tag"},
"instance_type": "{{user `aws_instance_type`}}",
"source_ami_filter": {
"filters": {
"virtualization-type": "hvm",
"name": "{{user `ami_filter_name`}}",
"root-device-type": "ebs",
"architecture": "x86_64"
},
    CODE

  4. Use the packer manifest option to build the AMI:

    ./konvoy-image build aws images/ami/centos-79.yaml --packer-manifest=work/centos-7-1658174984-TycMM/packer.json
2022/09/07 18:23:33 writing new packer configuration to work/centos-7-1662575013-zJUhP
2022/09/07 18:23:33 starting packer build
centos-7.9: output will be in this color.

    Now that your tags have been added to the AMI, you can continue to Advanced Configuration for AWS and finish building your clusters.
