/help

ChatOPS built in help:

Currently supported commands include:

• /sca - run all SCA tests via pre-commit
• /validate - run terraform validate
• /plan - plan the infrastructure (only examples)
• /apply - deploy the infrastructure and destroy afterwards (only examples)
• /idempotence - test idempotence: deploy, plan and destroy afterwards (only examples).

The 1^st command does not take arguments, the remaining take two:

• paths - a space delimitied list of module paths
• tf_version - (optional, defaults to the latest available) a space delimited list of Terraform versions to test the infrastrucure against.

Examples:

# run idempotence tests on listed modules with Terraform versions: 1.2 (latest patch available), 1.4 (latest patch available), 1.5.4.
/idempotence paths="examples/common_vmseries examples/panorama_standalone" tf_version="1.2 1.4 1.5.4"

# run validation tests with the latest available Terraform version on listed modules.
/validate paths="modules/vmseries modules/vnet examples/dedicated_vmseries"

Looks good to me, great work! Let's just confirm with Migara if we're OK with leaving "0.0.0.0/0" as the default behaviour.

P.S. Good catch on the random password generation. :)
