Referencing variable from a file in a template

[alexlykasov]

Hi guys! According to Takomo documentation, or at least as I understood it, we can load variables from a file by specifying --var-file name=FILE argument for the takomo deploy command.
I have variables.yml file with this content

buckets:
  - bucketName: bucket1
    expirationDays: 30
  - bucketName: bucket2
    expirationDays: 60

I have a template where I want to iterate over the buckets list like this:

  {{#each var.buckets}}
  Bucket{{bucketName}}:
    Type: AWS::S3::Bucket
    Properties:
      BucketName: {{bucketName}}
      LifecycleConfiguration:
        Rules:
          - ExpirationInDays: {{expirationDays}}
            Status: Enabled
  {{/each}}

And when I try deploying the stack npx tkm stacks deploy -y /mystack --var-file variables.yml, I'm getting the following error:
Template format error: YAML not well-formed.

Can you provide an example how to do such a thing in a correct way?

Hi, you don't have Resources block in your template. Did you intentionally leave it out from the snippet?

I was able to make it work using this template file:

Resources:
  {{#each var.buckets}}
  Bucket{{bucketName}}:
    Type: AWS::S3::Bucket
    Properties:
      BucketName: {{bucketName}}
      LifecycleConfiguration:
        Rules:
          - ExpirationInDays: {{expirationDays}}
            Status: Enabled
  {{/each}}

You can also adjust the logging level with --log debug or --log trace options to get more information on what actually happens. When using the trace logging level you can see the rendered template files which might help to spot the error.

What Takomo version you are using?

Thanks for the reply!
The template was fine, I just sent a snippet. Apparently, the problem was that I used an old version of Takomo, 2.12.1. I upgraded to the latest version and it works fine now.
In this regard, it would be nice if you started adding notes to new Takomo releases with info about what new features appear in which versions.

Glad to hear the latest version fixed the problem.

The change log can be found from this file https://github.com/takomo-io/takomo/blob/master/CHANGELOG.md

I also need to modify the release pipeline to make it automatically include the release notes to Github releases.
