I have a problem when in frontend dockerization, I face to this error when I run the code: content not from webpack is served from /app/public. And the container will Exited, do you know how can I solve the problem?
Thanks
I cloned a fresh copy of the repo and was able to build and run the app without error. Since
frontendis mostly Create React App boilerplate, which handles all the Webpack configuration, the source of the problem is hidden under all of CRA's magic.Assuming you didn't eject CRA or move files into or out of
public, it's possible that old packages are causing problems, as I haven't updated any of them since writing the post. Try updating CRA to the latest version.issues/8688
This issue started with the v3.4.1 upgrade, I listed 5-6 ways from this thread on how to fix it, from pinning to the 3.4.0 version, changing
docker-compose uptodocker-compose run.. for now I've settled adding a terminal to my compose file, but someone else pointed out the reason they closed the terminal is it could be a security risk. Ultimately the issue is when docker has the server running it thinks it's completed the job and exits.Hey Craig, fantastic tutorial here! I've used it as an inspiration for a cookiecutter that other people might find useful, let me know what you think: cookiecutter-react-django
That's really cool! When I get a minute, I'll update the post to link to your project as well. I imagine it will be a bit more convenient than cloning specific branches in the repo for the tutorial.
Hi Craig
Thank you for the tutorial. It scratches my back happily~. Appreciate it!
I have an issue while following your instructions. I installed axios in success and then after editing App.js according to the code in the end and tried to build as follows
I got this error
Do you have any ideas about what's wrong and what I'm missing?
Thank you and I look forward to your feedback soon~
Never mind. I forgot to uncomment lines in Dockerfile within frontend.
Afterward, it works.

That error is due to the frontend files not being in the expected folder after running
yarn build. I wasn't able to recreate that specific error, but I was unable to deploy to Heroku due to some mysterious error while trying to install Yarn in theDockerfile. I've updated dependencies inmasterand have since been able to build and deploy the app without problem. Trying pullingmasterand redeploying.Nice men, it's really helpfull. Good work!
This is great. I've often wondered whether docker would be a good fit for data viz.
Hi, excellent tutorial, everything worked like a charm. Just one question, why one-way volumes? Exactly how do they work and how to make good use of them? (Well, 3 actually)
Thanks!
Thanks. The only time I use on-way volumes is for managing the
node_modulesdirectory. I don't know the internals well, but with a two-way volume, when you rundocker-compose up, docker takes the files on your machine and inserts them in the newly-started container, overwriting any equivalent files that were in your image. This is usually what you want, so you don't have to rebuild the image every time you change your code, but the whole point of installing dependencies in an image is that they are independent of the machine running the container. Using a one-way volume prevents thenode_modulesdirectory on your computer from replacing the one in your docker image.Iam getting an error after running docker-compose up: Post unix/filesharing/share: net/http: request canceled (Client.Timeout exceeded while awaiting headers)
I just did a fresh, no-cache build on the
developmentbranch of the repo and I was able to load the page without error. The timeout error that you're getting suggests internet connection problems, but without more information, I'm not sure what the cause could be.Yes i managed to solve it by stopping my firewall.
