Hi all,
An update: I have upgraded the version to 2.8.0-SNAPSHOT.
With these version, I started to deploy a side-car container by using the property deployer.appl.kubernetes.additional-containers .
With these approach, the side-car container should be deployed before the application container. The application container should be started after side-car container is in ready state.
I considered to trigger a task by adding initContainer property, but in this case an image which I did not want would be deployed.
How can I sort the deployments of these containers?
The recommended way to do this is using Lifecycle Hooks https://kubernetes.io/docs/tasks/configure-pod-container/attach-handler-lifecycle-event/. I am working on an enhancement to expose postStart
and preStop
exec
handlers. httpGet
and tcpSocket
will be deferred for now.
Hi @dturanski,
I read the documentation you referenced and it seems that 'postStart' handler will fix my issue.
But there is one thing I wanted to ask. I am using 'shell' as entry point style. Will I be able to use 'shell' entry point style with these hooks?

I expect it to work. LMK if you have any issues.
Hi all,
I am triggering a task over scdf dashboard by using deployer properties. I want to execute a shell command right after the pod creation, before the application initialization.
I looked at the spring-cloud-dataflow-docs/configuration-kubernetes, but I could not find a proper property. Is it possible to execute a shell command as I mentioned?
the version of spring-cloud-data-flow 2.5.0.
Thanks :)
