java.io.FileNotFoundException: file doesn't exist when using -f with docker run

[Basma1912]

I am trying to use the docker image with the -f flag and it keeps saying no (No such file or directory)

If you mean the KafkaProperties file, this will need to be mounted into docker volume and then you can run it using -f flag

I copied kafkaproperties file inside the docker image , but still when i run it , it says (No such file or directory)

Something like this should do the trick:

docker run  -v /Users/omaral-safi/Code/consumer-monitoring.properties:/work/consumer-monitoring.properties -p 9739:9739 --rm omarsmak/kafka-consumer-lag-monitoring:latest -b kafka1:9092,kafka2:9092,kafka3:909 -c "my_awesome_consumer_group_01" -m "prometheus" -i 5000 -p 9739 -f /work/consumer-monitoring.properties

Whereby /Users/omaral-safi/Code/consumer-monitoring.properties is the file in your local machine and /work/consumer-monitoring.properties is the target file in the container and then you supply -f flag with /work/consumer-monitoring.properties because now is mounted into the container

Hello @Basma1912 , did you manage to solve your issue?

[Basma1912]

I did for some reason it didn't like the "-f config.properties" together , so the working Dockerfile looks like below:

# Use the official image as a parent image.
FROM amd64/openjdk:16

# Set the working directory.
WORKDIR /

# Copy the file from your host to your current location.
COPY ./config.properties /config.properties
COPY ./kafka-consumer-lag-monitoring.jar /kafka-consumer-lag-monitoring.jar 

# Add metadata to the image to describe which port the container is listening on at runtime.
EXPOSE 9739

# Run the specified command within the container.
CMD ["java", "-jar", "/kafka-consumer-lag-monitoring.jar", "-b" ,"kafkaserver:9092","--consumer.groups", "xxxxxx", "-f", "config.properties", "-m", "prometheus"]

I see, anyway I am working on major version 0.1.0 which includes the support for configuration via environment variables, hence you don't need to build an image for it, just from docker run directly, e.g:

docker run --rm -e MONiTORING_LAG_prometheus_HTTP_PORT=8080 -p 8080:8080 -e monitoring_lag_logging_rootLogger_appenderRef_stdout_ref=LogToConsole -e monitoring_lag_consumer_groups="test-*" -e kafka_bootstrap_servers=host.docker.internal:9092  2050e45c68bc
