@Marvin how to deploy prefect flow in a custom build docker from private gitlab docker registry?

To deploy a Prefect flow in a custom-built Docker image from a private GitLab Docker registry, you should follow these general steps. The specific commands and configurations will depend on your private registry and setup: 1. Create a Dockerfile: You need a Dockerfile that installs Prefect and includes your flow. You can base your image off of one of the provided

prefecthq/prefect

images or build your own image from scratch.

Dockerfile
FROM prefecthq/prefect:2-latest
RUN pip install your-dependencies
COPY your-flow.py /some/directory

2. Build the Docker Image: Build the Docker image and tag it appropriately for your private GitLab Docker registry.

sh
docker build -t <http://registry.gitlab.com/your-namespace/your-repo:your-tag|registry.gitlab.com/your-namespace/your-repo:your-tag> .

3. Push the Docker Image: Log in to your private GitLab registry and push your built image.

sh
docker login <http://registry.gitlab.com|registry.gitlab.com>
docker push <http://registry.gitlab.com/your-namespace/your-repo:your-tag|registry.gitlab.com/your-namespace/your-repo:your-tag>

4. Use the image in a work pool: When you specify a work pool for your Prefect deployments, you can specify the Docker image to use. This image can come from your private registry. Please ensure you configure your execution environment (Kubernetes, Docker daemon, etc.) to have access to your private GitLab registry. For more detailed information, you can refer to the Prefect Docker deployment guide here: Prefect Docker Guide. If you're using Kubernetes, make sure to create a secret to hold your GitLab registry credentials and update your deployment to use that secret. If you need more specific guidance or run into issues, searching the documentation with exact requirements or checking GitHub for related issues would be the next step.
