AzureAppService

az_webapp

Examples

# login
# the equivalent of (interactive) az_login is run outside of R

# subscription
# the azure login action automatically retrieves the enabled subscriptions GitHub Actions

# resource group
az_configure(resource_group = "hoad")
# you can also pass this argument to shiny_deploy_az for the one-call deployment
# you can also set this once and commit the resulting .azure/config
# but this is not easily available during testing, so it's set from R here
# because several apps are deployed below, `name` is set for each of them

# plan
plan <- "hoad"
# there's no way to set a plan default

# deploy shiny app using rocker image
az_configure(name = "hello-shiny")
az_webapp(
  # this image actually includes *more* than necessary
  # for example, it includes shinyserver, but just shiny would suffice
  deployment_container_image_name = "rocker/shiny:4.0.2",
  # above image has no `ENTRYPOINT` and/or `CMD` to start shiny by default.
  # so this `[COMMAND]` must be appended to `docker run`

    "Rscript",
    # setting shiny options for azure manually
    # equivalent to running shinycaas::shiny_opts_az()

    # remove getOption call https://github.com/subugoe/shinycaas/issues/37
    "-e shiny::runExample('01_hello',port=getOption('shiny.port'))"
  ),

# deploy shiny app using private image, here from muggle package
# below env vars and secrets are only available on github actions

  # for an easier way to set these arguments, see the {muggle} package
