Summary

  • Default images now use posit/connect on Docker Hub instead of ghcr.io/rstudio/rstudio-connect
  • Image tag format changed from {os}{version} (e.g. ubuntu2204-2026.03.1) to {version}-{os} (e.g. 2026.03.1-ubuntu-24.04)
  • image.tagPrefix replaced by image.os; launcher.defaultInitContainer.tagPrefix replaced by launcher.defaultInitContainer.os
  • Default content runtime images updated to posit/connect-content with current R, Python, and Quarto versions

Breaking changes

Old value New value
image.repository: ghcr.io/rstudio/rstudio-connect image.repository: posit/connect
image.tagPrefix: ubuntu2204- image.os: "ubuntu-24.04"
launcher.defaultInitContainer.repository: ghcr.io/rstudio/rstudio-connect-content-init launcher.defaultInitContainer.repository: posit/connect-content-init
launcher.defaultInitContainer.tagPrefix: ubuntu2204- launcher.defaultInitContainer.os: "ubuntu-24.04"

Chart version: 0.20.0

Test plan

  • make lint passes in charts/rstudio-connect
  • helm template renders correctly with default values
  • Verify posit/connect:2026.03.1-ubuntu-24.04 image exists on Docker Hub
  • Verify content runtime images exist in posit/connect-content

Migrate the rstudio-connect Helm chart from legacy ghcr.io/rstudio/
and rstudio/ registries to ghcr.io/posit-dev/. The image tag format
changes from {os}{version} to {version}-{os}, and tagPrefix is
replaced by os in both image and launcher.defaultInitContainer
configs. Default content runtime images updated to current R, Python,
and Quarto versions.
The grep pattern matched `rstudio-connect` which no longer
appears in the rendered image reference (`posit/connect`).
Python 3.14.3 and Quarto 1.9.36 match what's installed in
the posit/connect:2026.03.1-ubuntu-24.04 image.
The new posit/connect images define their own CMD and do not
include tini or /scripts/prestart.bash. Remove the hardcoded
command/args fallback when launcher is enabled, letting the
container use its default entrypoint.
prestart.bash is provided by the chart via ConfigMap, not the
container image. Keep the args fallback so it runs before
startup.sh when the launcher is enabled.
