Deploy stacks

Deploy stacks within the given command path.

Takomo also deploys stacks that the stacks within the command path depend on, even if they are outside the given command path. Takomo arranges the stacks in deployment order by stack dependencies, ensuring that it deploys the stacks in the correct order and in parallel when possible.

Takomo deletes stacks whose creation have failed earlier and then recreates them. Such failed stacks can't be updated, and deleting them is the only possible operation.


tkm stacks deploy [command-path] \
[--ignore-dependencies] \
[--interactive|-i] \
[--expect-no-changes] \
[--output <format>]

Positional arguments

  • command-path
    • Command path to select which stacks to deploy.
    • Optional, by default, Takomo deploys all stacks.


In addition to the common options, this command has the following options.

  • --ignore-dependencies
    • Ignore stack dependencies. By default, when a stack is deployed, its dependencies are deployed first, and then the stack itself. In some exceptional cases, you might want to deploy just one stack and skip its dependencies.
    • Bear in mind that this option is supported only when exactly one stack is deployed. Ignoring dependencies may lead into unexpected results, so you should use this option only in exceptional circumstances.
  • --interactive, -i
    • Choose the command path using autocompleting search.
  • --expect-no-changes
    • Fail the deployment if at least one stack has changes.
  • --output <format>
    • Print the command result using this format
    • Supported values: text, json, yaml

Deploy all stacks:

tkm stacks deploy

Deploy stacks within the given command path:

tkm stacks deploy /prod

Deploy only /dev/vpc.yml stack and its dependencies:

tkm stacks deploy /dev/vpc.yml

The region part must be specified if the stack has more than one region and you want to deploy it to only one region.

tkm stacks deploy /dev/vpc.yml/eu-west-1

Deploy exactly one stack and skip its dependencies:

tkm stacks deploy /cloudtrail.yml --ignore-dependencies
