In degauss-org/dht: A Collection of Functions to Assist Building DeGAUSS Containers

get DeGAUSS metadata online or from a Dockerfile

)

get_degauss_env_online(name = "fortunes")

Arguments

dockerfile_path	path to Dockerfile
name	name of DeGAUSS container to download Dockerfile from

It is assumed that each ENV instruction is on its own line and defines only one environment variable.

Value

named vector of DeGAUSS metatdata

get_degauss_env_dockerfile()["degauss_version"]

## End(Not run)
