#atmos-dev - July 2026

@Andriy Knysh (Cloud Posse) kubernetes components are ready for review. github.com/cloudposse/atmos/pull/2607

after this, the last PR is github.com/cloudposse/atmos/pull/2667 which needs to be rebased on main after merging 2607

@Andriy Knysh (Cloud Posse) Improve the mobile responsiveness of the new site theme

github.com/cloudposse/atmos/pull/2673

@Andriy Knysh (Cloud Posse) native support for atmos emulators + terraform test.
github.com/cloudposse/atmos/pull/2663

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2667 is passing now

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2683

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2681
This fixes some bugs in 1.222

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2678 this makes it easier to separate or to read the help because we separate custom commands from the built-in ones. Also cleans up our output of errors for displaying hints and explanations. Hints were frequently used in place of explanations.

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2687 a slight redesign of the Atmos CI badge.

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2268

@Andriy Knysh (Cloud Posse) support dot-notion in stack config.

github.com/cloudposse/atmos/pull/2139

components:
  terraform:
    vpc:
      metadata.component: vpc-base
      metadata.owner: platform
      vars:
        tags:
          environment: prod
          team: network

@Andriy Knysh (Cloud Posse) This adds support for CEL expressions on when conditions
github.com/cloudposse/atmos/pull/2689

workflows:
  deploy:
    steps:
      - name: plan-prod
        type: shell
        command: terraform plan
        when: !cel 'ci && stack == "prod" && status == "success"'

@Andriy Knysh (Cloud Posse) this replaces all make with atmos custom commands.

github.com/cloudposse/atmos/pull/2677

e.g. instead of make build, now we run:

atmos build --target linux

# or just this for the default.
atmos build

@Andriy Knysh (Cloud Posse) this ensures --profile works with custom commands
github.com/cloudposse/atmos/pull/2190

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2685

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/1515

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2669

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2696

this reduces the amount of output when running atmos --help ; we now support atmos --help=full or atmos --help=usage

Can you confirm if this is a bug with interactive workflows and custom commands? Should the new interactive step types (eg, choose, input, etc support non-tty? I think it should. It would mean a single workflow could work for local and ci usage.

Example:

workflows:
  build-manifests:
    dependencies:
      tools:
        kustomize: v5.0.3
    steps:
      - name: account
        type: choose
        prompt: "Account"
        options: [dev, prod]
        default: !env STACK_ACCOUNT dev
      - name: region
        type: choose
        prompt: "Region"
        options: [use1, euc1]
        default: !env STACK_REGION use1
      - name: tag
        type: input
        prompt: "Release tag"
        default: !env RELEASE_TAG latest
      - command: atmos kube build "{{ .steps.account.value }}-{{ .steps.region.value }}/tao" --tag "{{ .steps.tag.value }}" --env "{{ .steps.account.value }}" --output ".argocd/manifests/common-tao/kustomized.yaml"
        type: shell
      - command: atmos kube build "{{ .steps.account.value }}-{{ .steps.region.value }}/zen" --tag "{{ .steps.tag.value }}" --env "{{ .steps.account.value }}" --output ".argocd/manifests/common-zen/kustomized.yaml"
        type: shell

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2692 this is the foundational work that will be used to record ascii casts (videos) of every feature. The work was actually part of another branch, but I refactored it out into it's PR.

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2664 includes github.com/cloudposse/atmos/pull/2688
• after merging these going to focus on recording the demo casts and polishing off the documentation. Then we'll be ready for the next release.

@Andriy Knysh (Cloud Posse) this adds demos for almost every example: (PR is too big to review, but it's all .cast files and YAML workflows to generate the demos).
github.com/cloudposse/atmos/pull/2672

Instead, what makes more sense to review is the output: view the demos.

I see that pkg/auth/integrations/github/sts.go is locked to Atmos Pro. I have been using (self-hosted) version of ChainGuard's octo-sts for the past year. Is this something want to keep locked Atmos Pro?

@Andriy Knysh (Cloud Posse) this introduces a loop skill that is activated by /pr-maintenance-loop And when activated we'll periodically wake up, rebase, address the Code Rabbit review comments, ensure test coverage is over 85%, fix ci failures, and keep the PR title and description up to date, and then announce the PR is ready for final review.github.com/cloudposse/atmos/pull/2718

@Andriy Knysh (Cloud Posse) I gave atmos AI and atmos MCP a facelift. Improved the DX, cleaned up the UX, introduced more tools into the MCP so it can manage toolchains, vendor configs, set/get operations, as well has HCL editing. The docs also got a makeover.

We can now just run atmos mcp install and it will install by default the atmos MCP, as well as specifying presets defined in atmos.yaml. Added uninstall command too, support for http transports, and more.

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2749 this consolidates the stack schemas

QQs. If tools are defined at the project root level (eg, .tool-version), should custom commands have access to those tools defined at the project? Should it behave differently if a custom command defines dependencies.tools or does not define any?

Any opinion on choice options being determined at runtime? I would like to populate the options for choice in earlier step prior to reaching the step.

Related, any opinion on markdown not being pre-render before any steps: [] are executed? I would like to render .steps.<name>.output in markdown using markdown type.

Hey 👋 ,

Dropping the RDS IAM auth PRs here (full context in discussions #121):
- token — atmos aws rds token, ready for review → github.com/cloudposse/atmos/pull/2817
- connect — atmos aws rds connect + aws/rds integration, draft follow-on → github.com/cloudposse/atmos/pull/2818

Token's self-contained; connect builds on it and has a couple of open design Qs (embedding the Amazon RDS CA bundle vs fetch-on-demand / --ca-bundle, and the psql/mysql client-binary prereq) — kept it draft pending direction there. Happy to reshape either.

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2808

@Andriy Knysh (Cloud Posse) github.com/cloudposse/atmos/pull/2798

@Andriy Knysh (Cloud Posse) this one warrants a closer look and is an area you've spent the most time on over the years.
github.com/cloudposse/atmos/pull/2787

I don't know when it stopped working, but this formalizes and adds regression tests to ensure a "parent stack" can be decomposed into smaller files. It preserves the idea that component instances are unique, while allowing them to be split across multiple files.

Couple DX feedback:
1. I love spin type. It makes it feel like a native atmos command. However, it hide error messages. It needs a way to surface an error on non-zero exits.
a. Adding the ability to pass state (eg, outputs) that can be used by another step would be a bonus.
2. Support for GitHub Action style if: condition for steps would be useful.
a. Not really needed for shell or spin type steps, but it would be useful for choice types. It would allow for similar interactive experience that atmos provides when running commands that required stack or component inputs. eg, custom command that has flag marked optional (but really is required) could prompt user to select a option when flag value is a empty value.
3. Support for dynamic options for choice
a. We already discussed this. I just haven't spent time on solving it yet. Probably will start this evening.
