jaeger-all-in-one docker-compose.yaml configurations to store traces to postgresql

Question

Currently, I am using docker-compose.yaml file with a collector-gateway.yaml file as the otel collector for the traces to be sent up to jaeger. What i am trying to achieve is data persistence with postgresql and i am trying to make use of this github repo: text. However, i keep meeting this error upon starting up the docker container with docker-compose up.

Error Log:

jaeger-postgresql-jaeger-all-in-one-1  | {"level":"fatal","ts":1696996008.1216166,"caller":"./main.go:110","msg":"Failed to init storage factory","error":"grpc-plugin builder failed to create a store: error attempting to connect to plugin rpc client: fork/exec /etc/cmd/jaeger-pg-store: exec format error","stacktrace":"main.main.func1\n\t./main.go:110\ngithub.com/spf13/cobra.(*Command).execute\n\tgithub.com/spf13/[email protected]/command.go:940\ngithub.com/spf13/cobra.(*Command).ExecuteC\n\tgithub.com/spf13/[email protected]/command.go:1068\ngithub.com/spf13/cobra.(*Command).Execute\n\tgithub.com/spf13/[email protected]/command.go:992\nmain.main\n\t./main.go:243\nruntime.main\n\truntime/proc.go:267"}

For more context about my code docker-compose.yaml:

version: "3"

I have tried building the jaeger-plugin-store with CGO_ENABLED=0 GOARCH=amd64 GOOS=darwin since im on a mac system. Im still relatively new to go in general.

Weirdly enough, when i followed the normal instructions in their readme which was running jaeger-all-in-one as an executable from their binary and not through docker-compose it works but just cannot detect my postgres database. However, i preferably would want to run it with my docker-compose file instead.

The pertinent error is

fork/exec /etc/cmd/jaeger-pg-store: exec format error

This suggests incompatible binary format. When you're running from within a Docker container, your binary has a different view of the operating system than on your local machine, i.e. the Docker image you're using is built for Linux, but you're trying to point it to a plugin binary built for MacOS. You would need to build the plugin binary for Linux as well.
