Based on your description and the error you're encountering, I can provide some insights and potential solutions: 1. Root Cause: The error occurs during the Git clone step of your flow deployment, suggesting that the custom securityContext you're setting is preventing the worker from properly accessing or executing Git operations. This is typically related to file permissions and user contexts in the container. 2. Recommended Solutions: a. Use initContainers Approach: Instead of directly modifying the securityContext, you can use an initContainer to set up the proper permissions. Here's how you might modify your work pool configuration:

yaml
   initContainers:
   - name: init-permissions
     image: busybox
     command: ['sh', '-c', 'chown -R 1000:1000 /opt/prefect']
     volumeMounts:
     - name: prefect-data
       mountPath: /opt/prefect

b. Modify SecurityContext Safely: If you need to use a custom securityContext, ensure it includes the minimum required permissions:

yaml
   securityContext:
     runAsUser: 1000
     runAsGroup: 1000
     fsGroup: 1000
     allowPrivilegeEscalation: false

3. Best Practices: - Keep the Git clone directory writable by the worker process - Ensure the worker has read access to the necessary SSH keys or credentials - Consider using HTTPS instead of SSH for Git operations if possible 4. Debugging Steps: 1. Check the full pod logs for more detailed error messages 2. Verify the permissions on the mounted volumes 3. Confirm that your Git credentials are properly configured and accessible Could you share: 1. The specific securityContext configuration you're trying to use? 2. Are you using SSH or HTTPS for your Git repository access? 3. Are you using any custom volume mounts in your work pool configuration? This information would help me provide more targeted assistance for your specific setup. Also, while the default user works, it's understandable that you might need to run with custom security contexts for compliance or security reasons. We can work on finding a solution that maintains security while allowing the Git clone operation to succeed.

@Marvin 1.66537 2.HTTPS 3.Yes I am using custom volume mounts

You can save the above configuration as a JSON file (e.g.,

updated-job-template.json

) and update your work pool:

bash
prefect work-pool update your-pool-name --base-job-template updated-job-template.json

To help debug if you're still having issues: 1. Can you check the full pod logs and see if there are any permission-related messages before the Git clone error? 2. Are there any specific error messages in the logs about file access or directory permissions? 3. Could you confirm if the Git clone operation is trying to clone into the volume you've mounted, and if that volume has the correct permissions? Also, as a temporary test, you could try setting the securityContext with slightly more permissive settings to isolate whether it's purely a permissions issue:

yaml
securityContext:
  runAsUser: 66537
  runAsGroup: 66537
  fsGroup: 66537
  allowPrivilegeEscalation: false
  runAsNonRoot: true

Let me know if you need any clarification on these steps or if you'd like me to explain any part in more detail.

Thank you for providing the logs. I notice that the error occurs specifically when trying to clone from your internal Git repository (

<http://git.drwholdings.com|git.drwholdings.com>

). The error code 128 from Git typically indicates permission or authentication issues. Let me help you troubleshoot this more specifically. Given that you're using HTTPS and an internal Git repository, here are the most likely issues and their solutions: 1. Git Credentials Access First, let's ensure your Git credentials are properly configured. You'll need to modify your work pool job template to include Git credentials:

yaml
kubernetes:
  # Existing security context
  securityContext:
    runAsUser: 66537
    runAsGroup: 66537
    fsGroup: 66537

  # Add environment variables for Git
  env:
    - name: GIT_CONFIG_GLOBAL
      value: /opt/prefect/git/.gitconfig
    - name: GIT_CREDENTIALS
      valueFrom:
        secretKeyRef:
          name: git-credentials
          key: credentials

  # Mount points for Git configuration
  volumeMounts:
    - name: git-config
      mountPath: /opt/prefect/git
    # Your existing volume mounts...

  volumes:
    - name: git-config
      emptyDir: {}
    # Your existing volumes...

  # Add an init container to set up Git configuration
  initContainers:
    - name: git-init
      image: alpine/git
      command:
        - sh
        - -c
        - |
          mkdir -p /opt/prefect/git
          git config --global --add safe.directory '*'
          git config --global http.sslVerify false  # Only if needed for internal certificates
          echo "https://\${GIT_USERNAME}:\${GIT_PASSWORD}@git.drwholdings.com" > /opt/prefect/git/.git-credentials
          chmod 600 /opt/prefect/git/.git-credentials
          chown -R 66537:66537 /opt/prefect/git
      env:
        - name: GIT_USERNAME
          valueFrom:
            secretKeyRef:
              name: git-credentials
              key: username
        - name: GIT_PASSWORD
          valueFrom:
            secretKeyRef:
              name: git-credentials
              key: password
      volumeMounts:
        - name: git-config
          mountPath: /opt/prefect/git

2. Create the Kubernetes Secret Before applying the above configuration, create a Kubernetes secret with your Git credentials:

bash
kubectl create secret generic git-credentials \
  --from-literal=username=your-username \
  --from-literal=password=your-password \
  --from-literal=credentials="<https://your-username:your-password@git.drwholdings.com>"

3. SSL Certificate Handling If your internal Git server uses custom certificates, you might need to add them:

yaml
kubernetes:
  volumes:
    - name: ca-certificates
      configMap:
        name: custom-ca-certificates
  
  volumeMounts:
    - name: ca-certificates
      mountPath: /etc/ssl/certs/custom-ca.crt
      subPath: ca.crt

  env:
    - name: GIT_SSL_CAINFO
      value: /etc/ssl/certs/custom-ca.crt

4. Debugging Steps To help diagnose issues, add these environment variables to your job template:

yaml
env:
  - name: GIT_TRACE: "1"
  - name: GIT_CURL_VERBOSE: "1"

5. Alternative Approach Using Git Config If the above doesn't work, try this alternative approach:

yaml
initContainers:
  - name: git-setup
    image: alpine/git
    command:
      - sh
      - -c
      - |
        mkdir -p /opt/prefect/git
        git config --global --add safe.directory '*'
        git config --global credential.helper 'store --file=/opt/prefect/git/.git-credentials'
        git config --global http.sslVerify false  # Only if needed
        chown -R 66537:66537 /opt/prefect/git
    volumeMounts:
      - name: git-config
        mountPath: /opt/prefect/git

To implement these changes: 1. Save the modified configuration as a JSON file (e.g.,

updated-job-template.json

) 2. Update your work pool:

bash
prefect work-pool update your-pool-name --base-job-template updated-job-template.json

Questions to help further diagnose:

1. Is your Git repository using self-signed certificates? 2. Do you need to access the repository through a proxy? 3. Are there any specific corporate network policies that might affect HTTPS connections to your internal Git server? Let me know if you need any clarification or if you'd like me to explain any part of the solution in more detail.
