Hello, I am trying to achive the IPC socket communication between containers on rcar h3 bboard. I have created crosscompile containers using buildx. When I try running it containers created but communication not happening. here is the dockerfile : client: FROM alpine RUN apk add build-base WOR…

Hi @ bluepuma77 , I have created a bridge “mybridge” and attaching the container while running it. by passing --network=mybridge. by checking docker inspect mybridge it shows container2 i.e server is attached to bridge: root@h3ulcb:~# docker inspect mybridge [ { "Name": "mybridge", …

If the containers should be able to talk to each other, you should attach both to the Docker network. It seems only one is attached. For logs you can use docker logs -f <container-name> ( doc ).

Hi, Actually communication was happening but I was expecting the printf on console which didn’t happen. Later I ran containers in such a way that docker logs are written into a file. Later on inspecting the file I saw the clear communication logs. Below is the run command :slight_smile: docker ru…

docker logs should work, you should not need to mess with internal Docker files. One issue might be that you need to flush the output in your program, sometimes small output is stored in memory before being written to disk. In Python you would use something like: print("Hello, world!", flush=True…

ok. will check that option too.
