Create a Dockerfile for your App

Build a container containing your Shiny App. add_dockerfile() and add_dockerfile_with_renv() and add_dockerfile_with_renv() creates a generic Dockerfile, while add_dockerfile_shinyproxy(), add_dockerfile_with_renv_shinyproxy() , add_dockerfile_with_renv_shinyproxy() and add_dockerfile_heroku() creates platform specific Dockerfile.

Usage

add_dockerfile(
  path = "DESCRIPTION",
  output = "Dockerfile",
  pkg = get_golem_wd(),
  from = paste0("rocker/verse:", R.Version()$major, ".", R.Version()$minor),

FROM rocker/verse

without renv.lock file passed
`R.Version()$major`.`R.Version()$minor` is used as tag

expand

boolean. If TRUE each system requirement will have its own RUN line.

open

boolean. Should the Dockerfile/README/README be open after creation? Default is TRUE.

update_tar_gz

boolean. If TRUE and build_golem_from_source is also TRUE, an updated tar.gz is created.

build_golem_from_source

boolean. If TRUE no tar.gz is created and the Dockerfile directly mount the source folder.

extra_sysreqs

character vector. Extra debian system requirements.

source_folder

path to the Package/golem source folder to deploy. default is retrieved via get_golem_wd().

lockfile

path to the renv.lock file to use. default is NULL.
