Help! My Docker build is failing
I’m trying to set up a Dockerfile for a project using Puppeteer. But I’m running into a problem during the build process. Here’s what’s happening:
ERROR [4/5] COPY puppeteer-latest.tgz /home/pptruser/puppeteer-latest.tgz
failed to solve: failed to compute cache key: "/puppeteer-latest.tgz" not found: not found
It looks like the build can’t find the puppeteer-latest.tgz file. I’m pretty sure I’m following the official Dockerfile example, but something’s not working right.
Has anyone run into this before? Any ideas on how to fix it? I’m kind of stuck and would really appreciate some help!
hey there! i had a similar issue. try adding this to ur dockerfile:
RUN apt-get update && apt-get install -y wget
RUN wget https://github.com/puppeteer/puppeteer/releases/latest/download/puppeteer-latest.tgz
this should download the file during build. hope it helps!
I’ve faced this exact problem before. The issue likely stems from the puppeteer-latest.tgz file not being in the correct location relative to your Dockerfile. Double-check your project structure and make sure the file is in the same directory as your Dockerfile.
If that doesn’t solve it, consider switching to installing Puppeteer via npm directly in your Dockerfile. This approach is often more reliable and easier to maintain. You can do this by adding a line like:
RUN npm install puppeteer
This ensures you always get the latest version and eliminates the need for manual file management. Just remember to include the necessary dependencies for Puppeteer to run in a Docker environment.
I’ve encountered similar issues before and found that the error usually arises because the puppeteer-latest.tgz file isn’t being placed where Docker expects it during the build process. You might want to ensure that the file is actually available in your build context, or reconsider how you’re installing Puppeteer in your container. A workaround that has worked for me is to install Puppeteer directly inside the Docker container (for instance, using RUN npm install puppeteer) rather than copying a local tarball file. This method can streamline your build process and avoid path issues.
