The conditional can then be placed on the module definition instead of polluting each resource definition. For example, if you had several … Terraform: module for conditional include of related resources
The output of a Terraform child module is not shown by the root configuration/module. In order to have the child module output shown, you must explicitly define a root level output for it.

Unfortunately, with_fileglob only works on files local to the Ansible orchestrator host. It will not build a list of files from the remote directory, even if you use something like the copy module that has ‘remote_source: true’.

In a previous article, I showed how to manually setup Alternatives so that different versions of a binary could co-exist on a target machine. In that step-by-step example, we used the Terraform binary as an example, and placed two independent versions in /usr/local/bin, and then set the priority so that terraform14 was preferred. To do … Ansible: Ubuntu alternatives using the community.general collection

My aws-common-funcs.sh script provides a set of Bash functions … AWS: Bash helper functions for common AWS CLI calls
