Your user profile can be used to override every roles defaults values. For example, adding:
terraform_version : "0.9.6"
will install that specific version of terraform, instead of the default values.
If you want to see what you can override for a given role, check roles/{ROLE_NAME}/defaults/main.yml
If you want to see what you can override across all roles, you can try the following:
for dir in $(find . -type d -name "defaults"); do grep -vE "^---" ${dir}/main.yml ; done
Every role contains tags that you can specifically execute instead of running a full playbook.
There is a standard behind the tags naming, so if you just want to install intellij, which exists in developer/ide/intellij you can run either -t developer, -t ide or -t intellij.
The sections below cover install and build steps to get a full functioning linux box meeting whatever requirements you have.
