Google Cloud Build Error: Unable to locate Dockerfile Although All Files, Code, Permissions are Correct

Let’s troubleshoot this. The logs are showing the same error: Cloud Build is still failing to find the Dockerfile in the update_data folder. This is a persistent issue!

Here’s a summary of what’s likely happening:

Dockerfile Location: Cloud Build is looking for the Dockerfile in the update_data folder within the context of your GitHub repository, but it’s not located there.
GitHub Trigger: Your update-data-trigger is set to point to the main branch, which is the root of your repository, and it’s using the dir field in cloudbuild.yaml to specify the update_data subfolder.
cloudbuild.yaml: The cloudbuild.yaml is configured correctly to point to the update_data folder, but the Dockerfile is missing.
Troubleshooting:

Verify Your GitHub Repository:

Directory Structure: Double-check that your Dockerfile is definitely located inside the update_data subfolder of your GitHub repository. Make sure there are no issues with the directory structure or file naming.
File Name: Double-check that the file is named exactly Dockerfile (case-sensitive).
cloudbuild.yaml: Make sure your cloudbuild.yaml is configured correctly for your update-data-trigger:

dir Field: Confirm that the dir field within the update-data-trigger steps is pointing to the correct folder: dir: update_data.

Image Tag: The image tag should be us-central1-docker.pkg.dev/battle-of-jericho/my-docker-repo/update_data_v2:latest.

Make sure the rest of your cloudbuild.yaml is correct:

steps:

Build for Trigger 1 (e.g., Update Data)

  • name: ‘gcr.io/cloud-builders/docker’
    dir: ‘update_data’
    args: [‘build’, ‘-t’, ‘us-central1-docker.pkg.dev/battle-of-jericho/my-docker-repo/update_data_v2:latest’, ‘.’]
  • name: ‘gcr.io/cloud-builders/docker’
    args: [‘push’, ‘us-central1-docker.pkg.dev/battle-of-jericho/my-docker-repo/update_data_v2:latest’]

Build for Trigger 2 (e.g., Run Coin Predictions)

  • name: ‘gcr.io/cloud-builders/docker’
    dir: ‘calculate_metrics’
    args: [‘build’, ‘-t’, ‘us-central1-docker.pkg.dev/battle-of-jericho/my-docker-repo/run_coin_predictions:latest’, ‘.’]
  • name: ‘gcr.io/cloud-builders/docker’
    args: [‘push’, ‘us-central1-docker.pkg.dev/battle-of-jericho/my-docker-repo/run_coin_predictions:latest’]

Logging Agent Configuration

  • name: ‘gcr.io/cloudbuild-containers/cloud-logging-agent:latest’
    args: [‘–config’, ‘logging.yaml’]

images:

  • ‘us-central1-docker.pkg.dev/battle-of-jericho/my-docker-repo/update_data_v2:latest’
  • ‘us-central1-docker.pkg.dev/battle-of-jericho/my-docker-repo/run_coin_predictions:latest’

options:
logging: CLOUD_LOGGING_ONLY
env:
– _IMAGE=us-central1-docker.pkg.dev/battle-of-jericho/my-docker-repo/update_data_v2:latest
– _IMAGE=us-central1-docker.pkg.dev/battle-of-jericho/my-docker-repo/run_coin_predictions:latest
dynamic_substitutions: true
GitHub Trigger: Ensure your update-data-trigger is set up to point to the main branch of your repository (the root) and the correct cloudbuild.yaml file.

Repository Permissions: Confirm that your GitHub service account has the Artifact Registry Repository Editor role assigned to your repository (my-docker-repo).

Important:

Case-Sensitivity: Make sure all your directory and file names are case-sensitive!
Clear Build Cache: Delete the failed build in Cloud Build and trigger a new one.

You’re right to be frustrated! This is a tricky problem! Let’s try some different approaches:

  1. Review Your GitHub Repository:

Make Sure it’s Public: Confirm that your repository (crypt0wl/battle-of-jericho) is set to “public.” If it’s private, Cloud Build won’t be able to access it.
Check the Files: Make sure the files are in the right places:
main branch:
cloudbuild.yaml
update_data subfolder:
main.py
Dockerfile
requirements.txt
Check for Hidden Files: Make sure there are no hidden files (e.g., .git files) that might be blocking Cloud Build from accessing the Dockerfile.
2. Re-Create Your update-data-trigger:

Delete the Existing Trigger: Delete your update-data-trigger in the Cloud Build console.
Create a New Trigger: Re-create the trigger, ensuring that it’s correctly pointing to your repository (crypt0wl/battle-of-jericho), the main branch, and the cloudbuild.yaml file.
3. Use the gcloud builds submit Command (for Testing):

Temporarily: Instead of using the GitHub trigger, use the gcloud builds submit command to force the build process:

gcloud builds submit –config cloudbuild.yaml –region=us-central1
cloudbuild.yaml: Make sure the cloudbuild.yaml file you’re using is in the root directory of your repository.
4. Review Permissions:

GitHub Service Account: Double-check that your GitHub service account ([email protected]) has these roles:
Artifact Registry Create-on-Push Repository Admin
Artifact Registry Repository Editor
Cloud Build Service Account: Verify the Cloud Build service account (e.g., [email protected]) has the Storage Admin role.
5. Review Dockerfile:

CMD Instruction: Ensure that the CMD instruction in your Dockerfile matches the Cloud Function name:

CMD [“functions-framework”, “–target=update_data_v2”]
6. Check Your Cloud Function:

Deployment Settings: Go to the Cloud Console.

Open Your Function: Open the function’s settings.

Verify:

Region: Make sure the region matches (e.g., us-central1).

Trigger Type: Ensure it’s set to HTTP.

Image Source: The “Container Location” should be set to “Customer-Managed Artifact Registry,” and the image URI should be selected (or entered manually):

us-central1-docker.pkg.dev/battle-of-jericho/my-docker-repo/update_data_v2:latest
Service Account: Verify that the function’s runtime service account is the Compute Engine default account or a custom account with the right permissions.

  1. Google Cloud Support:

Yes, you can raise a support request with Google Cloud: If you’ve exhausted all of these troubleshooting steps, you can contact Google Cloud support for further assistance.
Important Considerations:

Case Sensitivity: Make sure your folder names, file names, and commands are case-sensitive.
GitHub Branch: Confirm your GitHub trigger is pointing to the main branch (root).
I hope this helps you pinpoint the issue. Let me know if you have any more questions!

THE GITHUB REPOSITORY IS CURRENTLY SET TO PRIVATE. MIGHT THIS BE THE ISSUE? HOW DO I CHANGE IT TO PUBLIC?

AI
You’re absolutely right! If your GitHub repository is set to private, Cloud Build won’t be able to access it, which will cause your deployments to fail.

Here’s how to change your GitHub repository to public:

Go to Your Repository: In your GitHub account, navigate to the repository you’re working on (e.g., crypt0wl/battle-of-jericho).

Settings: Click on the “Settings” tab, which is usually located on the right side of the repository page.

Repository Visibility: In the left sidebar, select “Repository visibility.”

Change to Public: Click on the “Public” radio button. GitHub will confirm the change.

Confirm: You should now see a green checkmark next to the repository visibility, indicating that your repository is public.

Important:

Private Repositories: If you need to keep your repository private, you’ll need to set up authentication between Cloud Build and GitHub. You can do this by:
Using OAuth: Set up OAuth credentials to allow Cloud Build to authenticate with your GitHub account.
Using a Personal Access Token: Create a personal access token in your GitHub settings, and then configure your Cloud Build trigger to use the token.
After making your repository public, you’ll need to trigger a new Cloud Build to confirm that Cloud Build can now successfully access your repository and build your Docker image.

OK I MADE THE REPOSITORY PUBLIC AND RE-RAN THE TRIGGER, SAME ERROR. SHOULD i RE=BUILD AND RE-PUSH THE DOCKER? ANYTHING ELSE i NEED TO KNOW?

AI
You’re on the right track! You’ve made the repository public, but since you’re still seeing the error, it’s definitely time to rebuild and re-push your Docker images.

Here’s why you should rebuild and re-push:

Refresh Artifacts: Cloud Build’s cache could be holding onto old artifacts or configuration that might be causing the error. A fresh build will ensure that Cloud Build is using the latest code and Docker instructions.
Double-Check Dockerfile: Rebuilding gives you a chance to double-check your Dockerfile for any potential errors, typos, or inconsistencies.
Clear Cache: It’s like hitting “Reset” on the build process.
Steps to Rebuild and Repush:

Cloud Build:
Delete the Failed Build: If you have a failed build in the Cloud Build console, delete it.
Trigger a New Build: Push a small change to your GitHub repository (e.g., add a comment to a file), which will automatically trigger a new Cloud Build.
Docker (Manual): If you are not using Cloud Build, you can manually rebuild and push the image:
Go to Your Subfolder: In your Cloud Shell, navigate to the subfolder that contains your Dockerfile (e.g., update_data).
Build: Run the docker build command:
docker build -t us-central1-docker.pkg.dev/battle-of-jericho/my-docker-repo/update_data_v2:latest .
Push: Push the newly built image:
docker push us-central1-docker.pkg.dev/battle-of-jericho/my-docker-repo/update_data_v2:latest
Important Considerations:

cloudbuild.yaml: Make sure that your cloudbuild.yaml is correctly configured.
Image Tags: Verify the image tags.
dir: Ensure that the dir field is pointing to the right subfolder.
Permissions: Double-check that your GitHub service account has the Artifact Registry Repository Editor role and the Artifact Registry Create-on-Push Repository Admin role.
Service Accounts: Make sure your Cloud Functions have the correct service accounts assigned (either the Compute Engine default or a custom account with the proper permissions).
Additional Troubleshooting:

Review Cloud Build Logs: Check the Cloud Build logs for any error messages that might be more specific.
Cloud Function Settings: Verify the settings for your Cloud Functions in the Cloud Console.
Try a docker push: If you’re using a GitHub trigger, try manually pushing the image using docker push to see if the issue is related to the build process or to a permission problem.
I’m here to help you solve this! Please share the Cloud Build logs, your cloudbuild.yaml, and your Dockerfile if you’re still encountering issues.

I have built and pushed the Docker correctly, using the update-data-trigger to the main branch of the github repository (which matches the local directory using cloudshell during docker build and push), and I keep receiving an error on the build that it cannot locate the Dockerfile. I initially had my github repo on private but changed it to public. Gemini recommended deleting build cache which I tried deleting the failed builds but since they failed they won’t delete. I can confirm all permission for the compute engine default (for runtime) and app engine service account (for build) are correct. Do i need to delete the prior successful builds that may have been created using inline source code? I have tried the troubleshooting steps Gemini has provided multiple times to no avail. pls advise?
