OK, so we’ve confirmed the base image source in our docker files was indeed the issue. Our livepush and general system instability was caused by using : FROM balenalib/raspberrypi3-alpine-python:3.8-latest
When we replaced the base image for all of our 6 containers with the image used in the Balena multi-container example: FROM balenalib/fincm3-python:3-stretch-run, All become well. Very snappy.
Curious about anyone’s thoughts. Note sure if we’re using docker image tags incorrectly which may have caused the issue? Regardless, breath of fresh air to have made progress on this.
Also! We can confirm for our application <1ms response time for requests using Redis as apposed to >30ms using http. We’ll be switching to Redis for sending data between containers from now on. This is a game changer for us and will make working in our 50ms hardware loop cycle much more friendly.
