Add Custom Commands

Atmos can be easily extended to support any number of custom CLI commands.

tip

Refer to Atmos Custom Commands for more information about Atmos Custom Commands

Custom commands are defined in the commands section in atmos.yaml CLI configuration file.

In this Quick Start guide, we'll define two custom commands to list the Atmos stacks in the infrastructure and the components in the stacks.

atmos.yaml

# Custom CLI commands
commands:
  - name: list
    description: Execute 'atmos list' commands
    # subcommands
    commands:
      - name: stacks
        description: |
          List all Atmos stacks.
        steps:
          - >
            atmos describe stacks --process-templates=false --sections none | grep -e "^\S" | sed s/://g
      - name: components
        description: |
          List all Atmos components in all stacks or in a single stack.

          Example usage:
            atmos list components
            atmos list components -s plat-ue2-dev
            atmos list components --stack plat-uw2-prod
            atmos list components -s plat-ue2-dev --type abstract
            atmos list components -s plat-ue2-dev -t enabled
            atmos list components -s plat-ue2-dev -t disabled
        flags:
          - name: stack
            shorthand: s
            description: Name of the stack
            required: false
          - name: type
            shorthand: t
            description: Component types - abstract, enabled, or disabled
            required: false
        steps:
          - >
            {{ if .Flags.stack }}
              {{ if eq .Flags.type "enabled" }}
                atmos describe stacks --stack {{ .Flags.stack }} --format json | jq '.[].components.terraform | to_entries[] | select(.value.vars.enabled == true)' | jq -r .key
              {{ else if eq .Flags.type "disabled" }}
                atmos describe stacks --stack {{ .Flags.stack }} --format json | jq '.[].components.terraform | to_entries[] | select(.value.vars.enabled == false)' | jq -r .key
              {{ else if eq .Flags.type "abstract" }}
                atmos describe stacks --stack {{ .Flags.stack }} --format json | jq '.[].components.terraform | to_entries[] | select(.value.metadata.type == "abstract")' | jq -r .key
              {{ else }}
                atmos describe stacks --stack {{ .Flags.stack }} --format json --sections none | jq ".[].components.terraform" | jq -s add | jq -r "keys[]"
              {{ end }}
            {{ else }}
              {{ if eq .Flags.type "enabled" }}
                atmos describe stacks --format json | jq '.[].components.terraform | to_entries[] | select(.value.vars.enabled == true)' | jq -r '[.key]' | jq -s 'add' | jq 'unique | sort' | jq -r "values[]"
              {{ else if eq .Flags.type "disabled" }}
                atmos describe stacks --format json | jq '.[].components.terraform | to_entries[] | select(.value.vars.enabled == false)' | jq -r '[.key]' | jq -s 'add' | jq 'unique | sort' | jq -r "values[]"
              {{ else if eq .Flags.type "abstract" }}
                atmos describe stacks --format json | jq '.[].components.terraform | to_entries[] | select(.value.metadata.type == "abstract")' | jq -r '[.key]' | jq -s 'add' | jq 'unique | sort' | jq -r "values[]"
              {{ else }}
                atmos describe stacks --format json --sections none | jq ".[].components.terraform" | jq -s add | jq -r "keys[]"
              {{ end }}
            {{ end }}

Run the following Atmos command to list all stacks in the infrastructure:

atmos list stacks

plat-gbl-dev
plat-gbl-prod
plat-gbl-staging
plat-ue2-dev
plat-ue2-prod
plat-ue2-staging
plat-uw2-dev
plat-uw2-prod
plat-uw2-staging

Run the following Atmos command to list all components in the stack plat-ue2-dev:

atmos list components -s plat-ue2-dev
