Get IP address for docker session of RStudio

[joepowers16]

Trying to use RStudio within docker.

The github guide to rocker says that you can use RStudio in a browser after you build the docker container for RStudio via

sudo docker run -d -p 8787:8787 -e PASSWORD=<password> --name rstudio rocker/rstudio

This creates a container, but the recommended method of retrieving the url (i.e., Docker Toolbox) is deprecated.

I have tried using this method from Stack to get the URL but no RStudio session appeared when I entered the output in the form of http://172.17.0.3:8787 in my browser.

docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_name_or_id

[joepowers16]

The correct url was http://localhost:8787/

Well done figuring that out!

If your question's been answered (even by you!), would you mind choosing a solution? It helps other people see which questions still need help, or find solutions if they have similar problems. Here’s how to do it:

FAQ: How do I mark a solution?

If your question has been answered, don't forget to mark the solution! How do I mark a solution? Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. Click the one that looks like a box with a checkmark in it: [image] Hovering over the mark solution button shows the label, "Select if this reply solves the problem". If you don't see the mark solution button, try clicking the three dots button ( ••• ) to expand the full set of options. When a solution is chosen, the icon turns green and the hover label changes to: "Unselect if this reply no longer solves the problem". Success! [solution_reply_author] …

As an additional tidbit here, the -p 8787:8787 is responsible for this. It says "map my local port 8787 to port 8787 on the container". For instance, if you used -p 8888:8787, then you would access the browser at http://localhost:8888

Also, docker inspect container_name is a handy way to get lots of information about the container The IP doesn't help a bunch in this case because often the docker network is a different one than your browser is using (of course, that is all configurable, but is complicated).

In any case, suffice it to say that -p someport:serviceport is your friend when you need to access a service running in docker locally!

If you are interested in developing a R project inside RStudio server in a Docker container, maybe package {devindocker} can interest you. This allows to launch a Docker for a specific project and you can manage libraries installation persistently using {renv}.
