From 7a1656ecc06d8fc3879b2604314279e0aec0e455 Mon Sep 17 00:00:00 2001 From: Paul Gauthier Date: Wed, 15 May 2024 10:11:11 -0700 Subject: [PATCH] aider: Add health check to Dockerfile for Jekyll server. # Aider chat conversation: USER: $ bash scripts/run.sh ruby 3.1.1p18 (2022-02-18 revision 53f5fc4236) [x86_64-linux-musl] Configuration file: /srv/jekyll/_config.yml Source: /srv/jekyll Destination: /srv/jekyll/_site Incremental build: disabled. Enable with --incremental Generating... done in 56.634 seconds. ASSISTANT: It looks like the Jekyll site is generating successfully. If you need any further changes or encounter any issues, please let me know! USER: how do i see the site? ASSISTANT: To see the site, you need to access it via a web browser. The Jekyll server is running inside the Docker container and is exposed on port 4000. You can access it by navigating to `http://localhost:4000` in your web browser. Here are the steps to follow: 1. Ensure the Docker container is running by executing the `bash scripts/run.sh` command. 2. Open a web browser. 3. Navigate to `http://localhost:4000`. This should display your Jekyll site. If you encounter any issues, please let me know! USER: Safari can't open page ASSISTANT: If Safari can't open the page, it might be due to a few reasons. Let's troubleshoot step-by-step: 1. **Check if the Docker container is running**: Ensure that the Docker container is still running. You can do this by running `docker ps` in your terminal. You should see a container with the name `my-jekyll-site` and the port mapping `0.0.0.0:4000->4000/tcp`. 2. **Check for any errors in the terminal**: Look at the terminal where you ran `bash scripts/run.sh` for any error messages. 3. **Check if the port is correctly exposed**: Ensure that the port 4000 is correctly exposed and mapped to your host machine. 4. **Try accessing the site using a different browser**: Sometimes, browser-specific issues can prevent access. Try using a different browser like Chrome or Firefox. 5. **Check firewall settings**: Ensure that your firewall settings are not blocking port 4000. If everything seems correct and you still can't access the site, let's add a step to the Dockerfile to ensure the server is running correctly. Here is an updated `scripts/Dockerfile` to include a health check: scripts/Dockerfile ```dockerfile <<<<<<< SEARCH # Use the official Jekyll image from Docker Hub FROM jekyll/jekyll:latest # Set the working directory WORKDIR /srv/jekyll # Copy the current directory contents into the container at /srv/jekyll COPY . /srv/jekyll # Install any needed packages specified in Gemfile RUN bundle install # Expose port 4000 to the host EXPOSE 4000 # Run Jekyll server CMD ["jekyll", "serve", "--host", "0.0.0.0"] ======= # Use the official Jekyll image from Docker Hub FROM jekyll/jekyll:latest # Set the working directory WORKDIR /srv/jekyll # Copy the current directory contents into the container at /srv/jekyll COPY . /srv/jekyll # Install any needed packages specified in Gemfile RUN bundle install # Expose port 4000 to the host EXPOSE 4000 # Health check to ensure the server is running HEALTHCHECK --interval=30s --timeout=10s --start-period=5s CMD curl -f http://localhost:4000 || exit 1 # Run Jekyll server CMD ["jekyll", "serve", "--host", "0.0.0.0"] >>>>>>> REPLACE ``` After updating the Dockerfile, rebuild the Docker image and run the container again: ```sh bash scripts/build.sh bash scripts/run.sh ``` Then try accessing `http://localhost:4000` again. If you still encounter issues, please let me know! --- scripts/Dockerfile | 3 +++ 1 file changed, 3 insertions(+) diff --git a/scripts/Dockerfile b/scripts/Dockerfile index 888a811ad..d4f6b6316 100644 --- a/scripts/Dockerfile +++ b/scripts/Dockerfile @@ -13,5 +13,8 @@ RUN bundle install # Expose port 4000 to the host EXPOSE 4000 +# Health check to ensure the server is running +HEALTHCHECK --interval=30s --timeout=10s --start-period=5s CMD curl -f http://localhost:4000 || exit 1 + # Run Jekyll server CMD ["jekyll", "serve", "--host", "0.0.0.0"]
