# Dynamo docs build and publish workflow
# Build:
# - Builds documentation using Docker container
# - Creates artifact for downstream use
# - Runs on: main, release/*, tags, PRs (docs changes only), manual dispatch
#
# Publish:
# - Main branch: publish to S3 under 'dev' (development docs)
# - Tagged commits: publish to S3 under 'archive/X.Y.Z' AND update 'latest' to match the release
# - Manual dispatch: publish specified version to archive (does NOT update 'latest')
# - PRs: no S3 publish (only internal preview deployment if targeting release branch)
# - Version manifest: automatically updated in S3 when publishing new versions (versions1.json)
# - Akamai: flushes cache for the target path after publish (when DOCS_AKAMAI_ENABLED=true)
#
# Required Configuration:
# - Repository variable: DOCS_PUBLISH_S3_TARGET_PATH (prefix under S3 bucket, e.g., "dynamo")
# - Repository variable: DOCS_BASE_URL (base URL for docs site, e.g., "https://docs.nvidia.com/dynamo")
# - Secrets: AWS credentials (DOCS_AWS_ACCESS_KEY_ID, DOCS_AWS_SECRET_ACCESS_KEY, DOCS_AWS_S3_BUCKET, DOCS_AWS_REGION)
# - Secrets: DOCS_TOKEN (GitHub PAT for PR preview deployment to external repo)
# - Secrets (optional): DOCS_AWS_IAM_STS_ROLE (for OIDC authentication instead of IAM keys)
# - Secrets (optional): DOCS_AKAMAI_* EdgeGrid credentials for cache flush
# - Variable (optional): DOCS_AKAMAI_ENABLED (set to 'true' to enable Akamai cache flush)
#
# Commit message flags:
# - '/skip-dev': skip publishing 'dev' on main branch
# - '/not-latest': publish version to archive but don't update 'latest'
