Add RMarkdown Vignette about containerit HOT 6 CLOSED

Initial build failed because of missing unknown pipe-operator.
Solution: added magrittr to packages suggests and to the initial vignette

from containerit.

Second build failed because of the missing method, docker_build.

"Fehler: Verarbeitung der Vignette 'basic.Rmd' mit folgender Diagnose fehlgeschlagen:
konnte Funktion "docker_build" nicht finden"

The method is not implemented in harbor (yet). We could either implement the method ourself or use googleComputeEngineR as a dependency (replaces harbor at the moment, because it is available on CRAN).

---> For now, I added googleComputeEngineR to package suggests and changed the vignette

from containerit.

Code part from the vignette doesn't look logical to me. Docker_build is building an image from a Dockerfile and expects a path to the dockerfolder and a name of the new image. 'container' seems to be misleading as a name here.

What kind of object shall method 'dockerfile' return? Easiest would be the path to the Dockerfile.

container <- dockerfile(sessionInfo(), ls())
docker_build(container) %>% docker_run(localhost)
image <- docker_build(container)

from containerit.

In the case you mentioned I expected dockerfile(..) to return an R object resembling a Dockerfile, so you could also do something like write(x = dockerfile(sessionInfo()), file = "./Dockerfile").

dockerfile(..) could take a path as an argument (default Dockerfile) though.

from containerit.

Basic vignette builds now locally, provided that the pipeline commented out:

#docker_build(container) %>% docker_run(localhost)
#image <- docker_build(container)
#con <- docker_run(image)

edited checklist

from containerit.

The vignette works, ist just must be updated when new features are complete.
