09/14/2021, 7:19 PMHey Kevin, prefect server starts the UI correctly, but how can I connect to my K8S deployment with external postgresql as in earlier versions?

I think you edit this to point to another postgres db. The agent contacts Prefect Cloud by default. To point it to server, you need to do
prefect backend serverr

1. prefect backend server
2. prefect server start
3. prefect local agent start

09/14/2021, 7:48 PMGreat and what would be the recommend way to switch from local agent to our K8s deployed server?
Raed Shabbir
09/14/2021, 8:37 PMWould it be just adding the following lines into the flow file?
Copy code
# comment out
# flow.executor = LocalExecutor()
#! For using kube
flow.executor = DaskExecutor()
# flow.run_config = KubernetesRun(
# image=<path to docker image>
# env={
# "PREFECT__CONTEXT__SECRETS__BITBUCKET_CLOUD_USERNAME": os.environ[
# "BITBUCKET_CLOUD_USERNAME"
# ],
# "PREFECT__CONTEXT__SECRETS__BITBUCKET_CLOUD_APP_PASSWORD": os.environ[
# "BITBUCKET_ACCESS_TOKEN"
# ],
# "PREFECT__LOGGING__LEVEL": "DEBUG",
# },
# image_pull_policy="Always",
# )k

prefect backend server✅ 1
