fgreg opened a new pull request #11: SDAP-133 Allow image to start with random
port
URL: https://github.com/apache/incubator-sdap-ningester/pull/11
Related to https://github.com/apache/incubator-sdap-ningesterpy/pull/9
This PR adds an option to the docker image to pick a random port for
internal communication during application startup.
This docker container contains 2 processes that communicate via a port. The
ningesterpy process listens on a port (default 5000) for communication from the
java process.
A problem was noticed when deploying this to AWS Batch. Namely that AWS
Batch runs containers in `network=host` mode instead of using a bridge network.
This causes port conflicts when AWS tries to run multiple instances of the
ningester container on the same host (because every ningesterpy instance is
trying to bind to port 5000 of the host).
The solution in this PR uses the feature added
https://github.com/apache/incubator-sdap-ningesterpy/pull/9 that allows
ningesterpy to select a random available port to bind to during startup so that
multiple instances of the ningester container can run on the same host at the
same time when using host networking.
