Planning block

Go to working directory: cd <live working dir>/<environment>/<block>

Terragrunt plan will pickup latest model revision from the git repository configured on terraform.tfvars within the block directory. It will then initialize terraform environment and show desired infrastructures changes. Run terragrunt plan to start planning. Run with --terragrunt-source-updateto force sources update to latest available revision.

Local testing, iterating

When testing local version of model (aka module) You need to set specific flags to inform terragrunt of the source relative path pointing to the git local working directory.

Assuming your home dir contains "live" and "modules" repositories:

~ |- live |- modules

To plan infrastructure enter live directory, environment, block:

cd <live working dir>/<environment>/<block>

i.e. cd live/prod/common

Run terragrunt plan specifying the relative path to reach module sources for the block:

terragrunt plan --terragrunt-source ../../../modules/<block>

i.e. terragrunt plan --terragrunt-source ../../../modules/common

Run with --terragrunt-source-updateto force sources update to latest available revision.

Planning all infrastructure block at once

Terragrunt plan-all will pickup latest revision of each infrastructure block, then initialize terraform environment and show desired infrastructures changes. Change to live working directory cd live

Run terragrunt plan-all to start planning. Run with --terragrunt-source-updateto force sources update to latest available revision from the associated git repository.

Local testing, iterating

Set source relative path to the git local working directory for module.

Assuming your home dir contains "live" and "modules" repositories:

~ |- live |- modules

To plan-all infrastructure at once enter live directory, environment:

cd <live working dir>/<environment>

i.e. cd live/prod

Run terragrunt plan-all and set the relative path to the module sources :

terragrunt plan-all --terragrunt-source ../../../modules

Run with --terragrunt-source-updateto force sources update to latest available revision.

Applying

Single block - latest revision from git module repository ( branch master)

Enter live directory, environment, block:

cd <live working dir>/<environment>/<block>

i.e. cd live/prod/common

Run terragrunt apply

Single block - Local testing, iterating

Enter live directory, environment, block:

cd <live working dir>/<environment>/<block>

i.e. cd live/prod/common

Run terragrunt apply --terragrunt-source ../../../modules/<block>

i.e. terragrunt apply --terragrunt-source ../../../modules/common

Run with --terragrunt-source-updateto force sources update to latest available revision.

All blocks at once - latest revision from git module repository ( branch master)

Enter live directory, environment, block:

cd <live working dir>/<environment>/<block>

i.e. cd live/prod/common

Run terragrunt apply-all. Run with --terragrunt-source-updateto force sources update to latest available revision.

All blocks at once - Local testing, iterating

Enter live directory, environment:

cd <live working dir>/<environment>

i.e. cd live/prod

Run terragrunt apply-all --terragrunt-source ../../../modules Run with --terragrunt-source-update flag to force sources update to the latest available revision.
