what

  • Add local search to atmos docs
  • Add atmos describe affected CLI command
  • Update docs website

why

  • Quickly search through documentation

  • The command atmos describe affected produces a list of the affected Atmos components and stacks given two Git commits. The command compares the final component sections (after all imports and deep-merging) for all Atmos components in all stacks, and produces a list of affected (changed) components in the stacks. The command also checks the changed files b/w the two commits and checks if the Terraform/Helmfile component folders are changed.

For the first commit, the command assumes that the repo root is a Git checkout (and throws an error if the repo is not a Git repository, does not have .git folder).

The second commit is specified on the command line using the --ref and --sha flags.
The --ref flag supports all standard Git References (https://git-scm.com/book/en/v2/Git-Internals-Git-References).

the ref will be the default branch (e.g. main) and the commit SHA will point to the HEAD of the branch.

test

If the current local branch changes a component (vars or env section) in any YAML stack config files that defines configuration for the component (either inline or via imports), the command shows all the affected components/stacks and the affected section:

atmos describe affected --ref refs/heads/main
[
   {
      "stack": "tenant2-ue2-staging",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.vars"
   },
   {
      "stack": "tenant2-ue2-prod",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.vars"
   },
   {
      "stack": "tenant2-ue2-dev",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.vars"
   },
   {
      "stack": "tenant1-ue2-staging",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.vars"
   },
   {
      "stack": "tenant1-ue2-dev",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.vars"
   },
   {
      "stack": "tenant1-ue2-test-1",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.vars"
   },
   {
      "stack": "tenant1-ue2-prod",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.vars"
   }
]

If the current local branch changes any base component (including the abstract ones), the command shows all the affected real components including all the components derived from the changed base component. For example, if we changed the variables for the test/test-component (which is a base for many derived components), the command shows the affected base and all the derived components:

atmos describe affected --ref refs/heads/main
[
  {
      "stack": "tenant1-ue2-dev",
      "component_type": "terraform",
      "component": "test/test-component",
      "affected": "stack.vars"
   },
   {
      "stack": "tenant1-ue2-dev",
      "component_type": "terraform",
      "component": "test/test-component-override",
      "affected": "stack.vars"
   },
   {
      "stack": "tenant1-ue2-dev",
      "component_type": "terraform",
      "component": "test/test-component-override-2",
      "affected": "stack.vars"
   },
   {
      "stack": "tenant1-ue2-dev",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.vars"
   }
]

If the current local branch changes the env section (ENV vars) for any base or derived components, the command shows the affected real components with the affected_section: "env":

atmos describe affected --ref refs/heads/main
[
  {
      "stack": "tenant1-ue2-dev",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.env"
   },
   {
      "stack": "tenant2-ue2-dev",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.env"
   },
   {
      "stack": "tenant2-ue2-staging",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.env"
   },
   {
      "stack": "tenant1-ue2-staging",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.env"
   },
   {
      "stack": "tenant2-ue2-prod",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.env"
   },
   {
      "stack": "tenant1-ue2-prod",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.env"
   },
   {
      "stack": "tenant1-ue2-test-1",
      "component_type": "terraform",
      "component": "test/test-component-override-3",
      "affected": "stack.env"
   }
]

If the current local branch changes a Terraform or Helmfile component (in components/terraform and components/helmfile folders), the command shows all the affected Atmos components/stacks and in the affected attribute it shows "affected": "terraform" if the Terraform code for the component has been changed, or "affected": "helmfile" if the Helmfile code for the component has been changed. For example, if we change the examples/complete/components/terraform/infra/vpc/main.tffile, it will affect all the Atmos components that provision the thevpc` Terraform component:
