QUESTION
I have a docker image felipeogutierrez/tpch-dbgen
that I build using docker-compose
and I push it to docker-hub registry using travis-CI
.
ANSWER
Answered 2020-Sep-22 at 11:28Docker has an unusual feature where, under some specific circumstances, it will populate a newly created volume from the image. You should not rely on this functionality, since it completely ignores updates in the underlying images and it doesn't work on Kubernetes.
In your Kubernetes setup, you create a new empty PersistentVolumeClaim, and then mount this over your actual data in both the init and main containers. As with all Unix mounts, this hides the data that was previously in that directory. Nothing causes data to get copied into that volume. This works the same way as every other kind of mount, except the Docker named-volume mount: you'll see the same behavior if you change your Compose setup to do a host bind mount, or if you play around with your local development system using a USB drive as a "volume".
You need to make your init container (or something else) explicitly copy data into the directory. For example:

I have a flink JobManager with only one TaskManager running on top of Kubernetes. For this I use a Service

instead of Deployment
. With this I can set the Pod IP to be stateful. Something that was not clear is that I had to set the Service
to use clusterIP: None
instead of type: ClusterIP
. So here is my service:
QUESTION
I created an image with Docker using this Dockerfile

ANSWER
Answered 2020-Sep-23 at 08:11The container in your pod exited with status 0
which means that the command in your container has successfully finished. You have not specified any restartPolicy
for your container so the default is Always
. Since your container finished - it will be restarted due to it's restart policy (actually you cannot even change that when using a deployment - it is always Always
.
The deployment should be used when you have some long running processes and you want to make sure that all instances of those processees are up and can be rolled out to new versions if needed.
For one hit processes that do something and then quit - you might better use Jobs.
