Draft blog post announcing mirai's HTTP launcher — target publish date: Tues 21 July

What this covers

  • mirai's HTTP launcher (introduced in 2.6.0) and the new headers argument in 2.7.1, now the primary way to authenticate.
  • Zero-config launching on Posit Workbench (2026.01+).
  • A worked Kubernetes Jobs recipe: build a Job manifest, POST it to the in-cluster API with the service-account bearer token, and let daemons dial back to host_url().
  • Notes on credentials-as-functions and TLS for untrusted networks.

Verification

The Kubernetes example was reproduced end-to-end against a local kind cluster (built an R+mirai image, RBAC + in-cluster driver pod, ran the exact recipe): 4 daemon Jobs were created via the API, all 4 daemons connected, and mirai_map() distributed work across the 4 daemon pods. Frontmatter passes scripts/validate-blog-posts.py.

Covers mirai's HTTP launcher (2.6.0) and the new `headers` argument in
2.7.1: zero-config on Posit Workbench, plus a worked Kubernetes Jobs
recipe. The Kubernetes example was verified end-to-end against a local
kind cluster.
