Description
This section focuses on configuring the object EnvoyFilter.
Examples
- 01-Envoy-add-response-headers
- 02-envoy-logging
Heads up
On the example 02-envoy-logging, it's a requisite to configure Istio's meshConfig.accessLogFile as /dev/stdout.
During the installation of the cluster itself, can be set with:
istioctl install --set profile=default -y --set meshConfig.accessLogFile=/dev/stdout
On the current scenario, I would recommend purging the Istio installation and reinstalling again, as I assume that you are testing this examples in a sandbox that you are free to "destroy".
Purging Istio
istioctl uninstall --purge
Then proceed with reinstalling Istio using the command from above.
What if I don't want to purge Istio?
Modify the IstioOperator similarly as mentioned here, and populate the object with the following fields:
spec:
profile: minimal
meshConfig:
accessLogFile: /dev/stdout
