Create Docker directory

Creates a docker/ directory for a given package. By default, assumes that docker/ should be a subdirectory of the specified package path.

Usage

create_docker_dir(pkg_path = ".", img_path = NULL)

Arguments

pkg_path

Path to the package directory. Default is "." for the current working directory, which assumes developer is working in R package root. However, this can be set to another path as needed.

img_path

Path to the write the docker image definition contents. The default NULL will use docker/ as a subdirectory of the pkg_path.

Value

Invisibly returns a list of package info returned by pkg_info. Primarily called for side-effect to create docker directory.

Details

This function is run as part of use_docker but can be used on its own.

Examples

if (FALSE) {
# Specify path to example package source and copy to tempdir()
# Note that in practice you do not need to copy to a tempdir()
# And in fact it may be easiest to use pracpac relative to your package directory root
ex_pkg_src <- system.file("hellow", package = "pracpac", mustWork = TRUE)
file.copy(from = ex_pkg_src, to = tempdir(), recursive = TRUE)

# Assuming default behavior then docker/ will be created under source root
create_docker_dir(pkg_path = file.path(tempdir(), "hellow"))

# Alternatively you can specify another directory above, below, or beside package source
create_docker_dir(pkg_path = file.path(tempdir(), "hellow"), img_path = file.path(tempdir(), "img"))
