I have that image (based on alpine)
otel/opentelemetry-collector-contrib:0.90.0
And try to open sh by some of that commands:
docker exec -it container_name /bin/bash
docker exec -it container_name /bin/ash
docker exec -it container_name /bin/sh
docker exec -it container_name ash
docker exec -it container_name sh
And no of these commands working for me...
How can I open terminal for that image?
If we run the image:
docker run -it --rm --name otel otel/opentelemetry-collector-contrib:0.90.0
And then get the container pid:
pid=$(docker container inspect otel --format '{{ .State.Pid }}')
We can inspect the container root filesystem like this:
sudo ls -l /proc/$pid/root/
Which shows us that the image contains only a single binary:
total 220580

(And a smattering of files in /etc).
There is no shell available in the container.
