# Workflow for deploying ontologies_api to stage/prod systems via capistrano. | |
# This workflow runs after a successeful execution of the unit test workflow and it | |
# can also be triggered manually. | |
# | |
# Required github secrets: | |
# | |
# CONFIG_REPO - github repo containing config and customizations for the API. Format 'author/private_config_repo' | |
# it is used for getting capistrano deployment configuration for stages on the github actions runner and | |
# PRIVATE_CONFIG_REPO env var is constructed from it which is used by capistrano on the remote servers for pulling configs. | |
# | |
# GH_PAT - github Personal Access Token for accessing PRIVATE_CONFIG_REPO | |
# | |
# SSH_JUMPHOST - ssh jump/proxy host though which deployments have to though if app servers are hosted on private network. | |
# | |
# DEPLOY_ENC_KEY - key for decrypting deploymnet ssh key residing in config/deploy_id_rsa_enc (see miloserdow/capistrano-deploy) | |
# this SSH key is used for accessing jump host, UI nodes, and private github repo. | |
