this is taking a bit of different approach:

  • Processes are responsible for mounting data. The exact interface is flexible, but over time this has felt more and more necessary. This is the first two commits, which could be independently merged into master if necessary.
  • Tries exposing ports on temporal server so the sync worker doesn't need to run on a separate pod (done but definitely needs more testing)
  • Tries to expose / mount the files by doing copies. This is super hacky at the moment, but seems like a more flexible and safer alternative to using the API.

Remaining:

  • properly wait for init containers to be ready for copy
  • wait to terminate the init container until all files are copied over
  • handle the mount naming / location / working directory properly

@jrhizor this is all done except for some normalisation tests that are failing. brain is fried so will look tmrw. see the KubePodProcess class for how we are detecting files + waiting for the init pod. Plenty of comments + clean up so should be pretty straightforward.

my plan today:

  • run e2e sync locally using this fixed version
  • increase limits for waiting for init containers
  • fix normalization tests
  • try to get this (and the parent PR) merged
  • e2e kube tests

* Use CDK to generate source that can be configured to emit a certain number of records and always works.

* Checkpoint: socat works from inside the docker container.

* Override the entry point.

* Clean up and add ReadMe.

* Clean up socat.

* Checkpoint: connect to Kube cluster and list all the pods.

* Checkpoint: Sync worker pod is able to send output to the destination pod.

* Checkpoint: Sync worker creates Dest pod if none existed previously. It also waits for the pod to be ready before doing anything else. Sync worker will also remove the pod on termination.

* update readme

* Checkpoint: Dest pod does nott restart after finishing. Comment out delete command in Sync worker.

* working towards named pipes

* named pipes working

* update readme

* WIP named pipe / socat sidecar kube port forwarding (#3518)

* nearly working sources

* update

* stdin example

* move all kube testing yamls into the airbyte-workers directories. sort the airbyte-workers resource folder; place all the poc yamls together.

* Format.

* Put back the original KubeProcessBuilderFactory.

* Fix slight errors.

* Checkpoint: Worker pod knows its own IP. Successfully starts and writes to Dest pod after refactor.

* remove unused file and update readme

* Dest pod loops back into worker pod. However, the right messages do not seem to be passing in.

* Switch back to worker ip.

* SWEET VICTORY!.

* wrap kube pod in process (#3540)

also clean up kubernetes deploys.

* More clean up. (#3586)

The first 6 points of #3464.

The only interesting thing about this PR is the kube pod shutdown. For whatever reason, the OkHttpPool isn't respecting the evictAll call and 1 idle thread remains. So instead of shutting down immediately, the worker pod shuts down after 5 mins when the idle thread id reaped. There isn't an easy way to modify the pool's idle reap configuration now. I do not think this issue is blocking since it's relatively benign, so I vote we create a ticket and come back to this once we do an e2e test.

* Implements redirecting standard error as well. (#3623)

* Clean up before next implementation.

* kube process launching (#3790)

* processes must handle file mounting

* remove comment

* default to base entrypoint

* use process builder factory / select stdin / use a pool of ports

* fix up

* add super hacky copying example

* Checkpoint: Works end to end!

* Checkpoint: Use API to make sure init container is ready instead of blind sleep. Propagate exception in DefaultCheckConnectionWorker.

* Refactor KubePodProcess. Checked to make sure everything still works.

* Format.

* Clean up code. Begin putting this into variables and breaking up long constructor function.

* Add comments to explain what is happening.

* fix normalization test

* increase timeout for initcontainer
