Integration with SnappyFlow

  • There are default variables available for all supported cloud providers.
  • These variables support passing credentials required to access desired cloud environment and also setting networks, regions, etc.,
  • All default variables are sourced from cloud profile and accounts sections of snappyflow.
  • All values along with variables passed from UI using parameters.json are written to values.tfvars file except variables masked sensitive in template execution directory
  • "access_key", "secret_key", "session_token","vsphere_user", "vsphere_password","openstack_username", "openstack_password" are not populated inside values.tfvars file, they are marked sensitive variables
  • optionally one can include terrafrom.tfvars file with some variables values defined by default

terrafrom and ansible commands executed from within template directory

export TF_PLUGIN_CACHE_DIR=/data/deepinight/terraform-plugin-cache && terraform init -input=false
terraform apply -input=false -var-file="values.tfvars" 

export ANSIBLE_CONFIG=./ansible/ansible.cfg
ansible-playbook -b -v -i artifacts/hosts.ini --user=ubuntu --key-file=./keys/awskube.pem ansible/playbook.yml

terraform destroy -force -var-file="values.tfvars"
