I want to play with Docker but need to get some fundamentals down straight. A couple of reasons, I want to utilize Shiny Studio and I would also like to use Continuous Development functions from Gitlab.
Here are some fundamental Docker commands that I took from this tutoral by rOpenSci Labs
The first FROM
The docker image you want to use.
FROM rocker/verse:3.3.2
The RUN command executes shell commands. Common usage would include install required packages.
RUN R -e "install.packages('gapminder', repos = 'http://cran.us.r-project.org')"
The ADD command allows you to add files
ADD analysis.R /home/rstudio/
Build the image
docker build -t my-r-image .
Launch the image.
docker run --rm -p 8787:8787 my-r-image
The period
Below is a .gitlab-cy.yml file; it seems there are some similarities between the Docker commands above.
image: rocker/verse:3.4.1
pages:
stage: deploy
script:
- Rscript -e "bookdown::render_book('index.Rmd', 'all', output_dir = 'public')"
artifacts:
paths:
- public
only:
- master
I tried these steps on my Linux box and was getting a permission denied error. An extra step of creating a user group is required.
The video in this tutorial is what helped me figure it out.
I will save for another post on why in the world you would want to do these things!
